I have the following folder structure which is located on D partition and it is outside of MVC application:
D:\item\html_file.html
D:\item\content\style.css
D:\item\js\site.js
the html_file.html has reference to js and css like:
<link href="content/style.css" ... />
<script src='js/site.js'>
And in MVC action I have something like:
[HttpGet]
public ActionResult GetItem(string id)
{
if (string.IsNullOrWhiteSpace(id)) {
throw new HttpException((int) HttpStatusCode.NotFound, "The id doesn't exist");
}
// get/verify user's rights and permissions
try {
string file = #"D:\item\html_file.html";
return File(file, MimeMapping.GetMimeMapping(file));
} catch (Exception e) {
// return 404
}
}
But that no CSS and JS files were loaded (it gave me 404, trying to access www.blabla.com/myCtrl/getitem/content/style.css).
My question: how to load those css and js which are outside of MVC application ?
Thanks
You assume that your server's current position is inside the item folder:
<link href="content/style.css" ... />
<script src='js/site.js'>
However, it might be not the case. If you add a slash to the paths
<link href="/content/style.css" ... />
<script src='/js/site.js'>
then they will be searched inside the root folder of your application. If the item folder happens to be that, then this will solve your problem. If not, then you will need to add a prefix to this, containing their path starting from the root, just remember to start the paths with slash.
I'm trying to upload a file using PrimeFaces, but the fileUploadListener method isn't being invoked after the upload finishes.
Here is the view:
<h:form>
<p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
And the bean:
#ManagedBean
#RequestScoped
public class FileUploadController {
public void handleFileUpload(FileUploadEvent event) {
FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
I've placed a breakpoint on the method, but it's never called. When using mode="simple" and ajax="false", it is been invoked, but I want it to work in the advanced mode. I'm using Netbeans and Glassfish 3.1.
How to configure and troubleshoot <p:fileUpload> depends on PrimeFaces and JSF version.
All PrimeFaces versions
The below requirements apply to all PrimeFaces versions:
The enctype attribute of the <h:form> needs to be set to multipart/form-data. When this is absent, the ajax upload may just work, but the general browser behavior is unspecified and dependent on form composition and webbrowser make/version. Just always specify it to be on the safe side.
When using mode="advanced" (i.e. ajax upload, this is the default), then make sure that you've a <h:head> in the (master) template. This will ensure that the necessary JavaScript files are properly included. This is not required for mode="simple" (non-ajax upload), but this would break look'n'feel and functionality of all other PrimeFaces components, so you don't want to miss that anyway.
When using mode="simple" (i.e. non-ajax upload), then ajax must be disabled on any PrimeFaces command buttons/links by ajax="false", and you must use <p:fileUpload value> with <p:commandButton action> instead of <p:fileUpload listener>.
So, if you want (auto) file upload with ajax support (mind the <h:head>!):
<h:form enctype="multipart/form-data">
<p:fileUpload listener="#{bean.upload}" auto="true" /> // For PrimeFaces version older than 8.x this should be fileUploadListener instead of listener.
</h:form>
public void upload(FileUploadEvent event) {
UploadedFile uploadedFile = event.getFile();
String fileName = uploadedFile.getFileName();
String contentType = uploadedFile.getContentType();
byte[] contents = uploadedFile.getContents(); // Or getInputStream()
// ... Save it, now!
}
Or if you want non-ajax file upload:
<h:form enctype="multipart/form-data">
<p:fileUpload mode="simple" value="#{bean.uploadedFile}" />
<p:commandButton value="Upload" action="#{bean.upload}" ajax="false" />
</h:form>
private transient UploadedFile uploadedFile; // +getter+setter
public void upload() {
String fileName = uploadedFile.getFileName();
String contentType = uploadedFile.getContentType();
byte[] contents = uploadedFile.getContents(); // Or getInputStream()
// ... Save it, now!
}
Do note that ajax-related attributes such as auto, allowTypes, update, onstart, oncomplete, etc are ignored in mode="simple". So it's needless to specify them in such case.
Also note that the UploadedFile property is declared transient just to raise awareness that this is absolutely not serializable. The whole thing should be placed in a request scoped bean instead of a view or even session scoped one. If this is the case, then you can safely remove the transient attribute.
Also note that you should immediately read and save the file contents inside the abovementioned methods and not in a different bean method invoked by a later HTTP request. This is because technically speaking the uploaded file contents is request scoped and thus unavailable in a later/different HTTP request. Any attempt to read it in a later request will most likely end up with java.io.FileNotFoundException on the temporary file and only cause confusion.
PrimeFaces 8.x or newer
Configuration is identical to the 5.x version info below, but if your listener is not called, check if the method attribute is called listener and not fileUploadListener like as in versions before 8.x.
PrimeFaces 5.x
This does not require any additional configuration if you're using at least JSF 2.2 and your faces-config.xml is also declared conform at least JSF 2.2 version. You do not need the PrimeFaces file upload filter at all and you also do not need the primefaces.UPLOADER context parameter in web.xml. In case it's unclear to you how to properly install and configure JSF depending on the target server used, head to How to properly install and configure JSF libraries via Maven? and "Installing JSF" section of our JSF wiki page.
If you're however not using JSF 2.2 yet and you can't upgrade JSF 2.0/2.1 to 2.2 yet (should be effortless though when already on a Servlet 3.0 compatible container), then you need to manually register the below PrimeFaces file upload filter in web.xml (it will parse the multi part request and fill the regular request parameter map so that FacesServlet can continue working as usual):
<filter>
<filter-name>primeFacesFileUploadFilter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>primeFacesFileUploadFilter</filter-name>
<servlet-name>facesServlet</servlet-name>
</filter-mapping>
The <servlet-name> value of facesServlet must match exactly the value in the <servlet> entry of the javax.faces.webapp.FacesServlet in the same web.xml. So if it's e.g. Faces Servlet, then you need to edit it accordingly to match.
PrimeFaces 4.x
The same story as PrimeFaces 5.x applies on 4.x as well.
There's only a potential problem in getting the uploaded file content by UploadedFile#getContents(). This will return null when native API is used instead of Apache Commons FileUpload. You need to use UploadedFile#getInputStream() instead. See also How to insert uploaded image from p:fileUpload as BLOB in MySQL?
Another potential problem with native API will manifest is when the upload component is present in a form on which a different "regular" ajax request is fired which does not process the upload component. See also File upload doesn't work with AJAX in PrimeFaces 4.0/JSF 2.2.x - javax.servlet.ServletException: The request content-type is not a multipart/form-data.
Both problems can also be solved by switching to Apache Commons FileUpload. See PrimeFaces 3.x section for detail.
PrimeFaces 3.x
This version does not support JSF 2.2 / Servlet 3.0 native file upload. You need to manually install Apache Commons FileUpload and explicitly register the file upload filter in web.xml.
You need the following libraries:
commons-fileupload.jar
commons-io.jar
Those must be present in the webapp's runtime classpath. When using Maven, make sure they are at least runtime scoped (default scope of compile is also good). When manually carrying around JARs, make sure they end up in /WEB-INF/lib folder.
The file upload filter registration detail can be found in PrimeFaces 5.x section here above. In case you're using PrimeFaces 4+ and you'd like to explicitly use Apache Commons FileUpload instead of JSF 2.2 / Servlet 3.0 native file upload, then you need next to the mentioned libraries and filter also the below context param in web.xml:
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>commons</param-value><!-- Allowed values: auto, native and commons. -->
</context-param>
Troubleshooting
In case it still doesn't work, here are another possible causes unrelated to PrimeFaces configuration:
Only if you're using the PrimeFaces file upload filter: There's another Filter in your webapp which runs before the PrimeFaces file upload filter and has already consumed the request body by e.g. calling getParameter(), getParameterMap(), getReader(), etcetera. A request body can be parsed only once. When you call one of those methods before the file upload filter does its job, then the file upload filter will get an empty request body.
To fix this, you'd need to put the <filter-mapping> of the file upload filter before the other filter in web.xml. If the request is not a multipart/form-data request, then the file upload filter will just continue as if nothing happened. If you use filters that are automagically added because they use annotations (e.g. PrettyFaces), you might need to add explicit ordering via web.xml. See How to define servlet filter order of execution using annotations in WAR
Only if you're using the PrimeFaces file upload filter: There's another Filter in your webapp which runs before the PrimeFaces file upload filter and has performed a RequestDispatcher#forward() call. Usually, URL rewrite filters such as PrettyFaces do this. This triggers the FORWARD dispatcher, but filters listen by default on REQUEST dispatcher only.
To fix this, you'd need to either put the PrimeFaces file upload filter before the forwarding filter, or to reconfigure the PrimeFaces file upload filter to listen on FORWARD dispatcher too:
<filter-mapping>
<filter-name>primeFacesFileUploadFilter</filter-name>
<servlet-name>facesServlet</servlet-name>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
There's a nested <h:form>. This is illegal in HTML and the browser behavior is unspecified. More than often, the browser won't send the expected data on submit. Make sure that you are not nesting <h:form>. This is completely regardless of the form's enctype. Just do not nest forms at all.
If you're still having problems, well, debug the HTTP traffic. Open the webbrowser's developer toolset (press F12 in Chrome/Firebug23+/IE9+) and check the Net/Network section. If the HTTP part looks fine, then debug the JSF code. Put a breakpoint on FileUploadRenderer#decode() and advance from there.
Saving uploaded file
After you finally got it to work, your next question shall probably be like "How/where do I save the uploaded file?". Well, continue here: How to save uploaded file in JSF.
You are using prettyfaces too? Then set dispatcher to FORWARD:
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
One point I noticed with Primefaces 3.4 and Netbeans 7.2:
Remove the Netbeans auto-filled parameters for function handleFileUpload i.e. (event) otherwise event could be null.
<h:form>
<p:fileUpload fileUploadListener="#{fileUploadController.handleFileUpload(event)}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
Looks like javax.faces.SEPARATOR_CHAR must not be equal to _
Putting p:fileUpload inside a h:form solved the problem at my case.
I had same issue with primefaces 5.3 and I went through all the points described by BalusC with no result. I followed his advice of debugging FileUploadRenderer#decode() and I discovered that my web.xml was unproperly set
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>auto|native|commons</param-value>
</context-param>
The param-value must be 1 of these 3 values but not all of them!! The whole context-param section can be removed and the default will be auto
bean.xhtml
<h:form enctype="multipart/form-data">
<p:outputLabel value="Choose your file" for="submissionFile" />
<p:fileUpload id="submissionFile"
value="#{bean.file}"
fileUploadListener="#{bean.uploadFile}" mode="advanced"
auto="true" dragDropSupport="false" update="messages"
sizeLimit="100000" fileLimit="1" allowTypes="/(\.|\/)(pdf)$/" />
</h:form>
Bean.java
#ManagedBean
#ViewScoped
public class Submission implements Serializable {
private UploadedFile file;
//Gets
//Sets
public void uploadFasta(FileUploadEvent event) throws FileNotFoundException, IOException, InterruptedException {
String content = IOUtils.toString(event.getFile().getInputstream(), "UTF-8");
String filePath = PATH + "resources/submissions/" + nameOfMyFile + ".pdf";
MyFileWriter.writeFile(filePath, content);
FacesMessage message = new FacesMessage(FacesMessage.SEVERITY_INFO,
event.getFile().getFileName() + " is uploaded.", null);
FacesContext.getCurrentInstance().addMessage(null, message);
}
}
web.xml
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.xhtml</url-pattern>
</servlet-mapping>
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
Neither of the suggestions here were helpful for me. So I had to debug primefaces and found the reason of the problem was:
java.lang.IllegalStateException: No multipart config for servlet fileUpload
Then I have added section into my faces servlet in the web.xml. So that has fixed the problem:
<servlet>
<servlet-name>main</servlet-name>
<servlet-class>org.apache.myfaces.webapp.MyFacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
<multipart-config>
<location>/tmp</location>
<max-file-size>20848820</max-file-size>
<max-request-size>418018841</max-request-size>
<file-size-threshold>1048576</file-size-threshold>
</multipart-config>
</servlet>
For people using Tomee or Tomcat and can't get it working, try to create context.xml in META-INF and add allowCasualMultipartParsing="true"
<?xml version="1.0" encoding="UTF-8"?>
<Context allowCasualMultipartParsing="true">
<!-- empty or not depending your project -->
</Context>
With JBoss 7.2(Undertow) and PrimeFaces 6.0 org.primefaces.webapp.filter.FileUploadFilter should be removed from web.xml and context param file uploader should be set to native:
<context-param>
<param-name>primefaces.UPLOADER</param-name>
<param-value>native</param-value>
</context-param>
I had the same issue, due to the fact that I had all the configuration that describe in this post, but in my case was because I had two jQuery imports (one of them was PrimeFaces's bundled jQuery) which caused conflicts to upload files.
Manually adding / loading jQuery with PrimeFaces results in Uncaught TypeErrors
As I have already mentioned in topic, I have a MVC site and I need to disable loading it into IFrame.
I have created simple page for testing purpose and I try to load into two IFrames my site and Google.com. I can see that my site is loaded but Google isn't. It means that it's necessary to change something in my MVC site.
<!DOCTYPE html>
<html>
<body>
<iframe src="http://localhost:61831/" width="1200" height="800">
<p>Your browser does not support iframes.</p>
</iframe>
<iframe src="http://google.com" width="1200" height="800">
<p>Your browser does not support iframes.</p>
</iframe>
</body>
</html>
So what and where in MVC site I have to write to achieve that?
It is possible to use X-Frame-Options HTTP header attribute to avoid ASP.NET MVC application be opened in IFrame.
There are several different way to insert this attribute to HTTP header:
1.Configure IIS to add this attribute to all HTTP responses
2.Set this attribute in every necessary action method of every controller
public class HomeController : Controller
{
public ActionResult Index()
{
Response.AppendHeader("X-Frame-Options", "SAMEORIGIN");
return View();
}
}
3.Create C# attribute in a way described here and apply it to action methods and controllers
[HttpHeader("X-Frame-Options", "SAMEORIGIN")]
public class HomeController : Controller
{
public ActionResult Index()
{
}
}
4.Set this attribute in Global.asax file
public class MvcApplication : HttpApplication
{
protected void Application_Start()
{
...
}
protected void Application_PreSendRequestHeaders(object sender, EventArgs e)
{
Response.AppendHeader("X-Frame-Options", "SAMEORIGIN");
}
}
Simple and quick Solution is to add following in Global.asax -
protected void Application_PreSendRequestHeaders(object sender, EventArgs e)
{
Response.AddHeader("X-Frame-Options", "SAMEORIGIN");
}
Then give a try with iframe. Pages will not open in iframes. HTH.
You can also add an entry in web.config:
<system.webServer>
...
<httpProtocol>
<customHeaders>
<add name="X-Frame-Options" value="SAMEORIGIN" />
</customHeaders>
</httpProtocol>
...
</system.webServer>
You can configure IIS to always append the X-Frame-Options SAMEORIGIN header in it's responses.
From IIS Management Console, select your application.
In the main panel, double click Http Response Headers.
Click Add from the upper right pane.
Set the name to X-Frame-Options and the value to SAMEORIGIN then
click OK.
This should prevent your site from being loaded into an iframe on a different host, without using any javascript or any extra code.
See developper.mozilla.org for the header documentation and technet.microsoft.com for IIS' configuration.
As DrewMan suggested, you want to use X-Frame-Options header.
I would suggest you to download Nuget Package NWebsec and there's MVC specific package. Also check out the configuration part.
I have for example theme test. How to set this theme using Java code in Primefaces ? I don't want to use context param primefaces.THEME and i don't want to use <p:themeSwitcher>.
One more way to do this: include stylesheet to your pages template:
<h:body>
<h:outputStylesheet library="primefaces-#{themesBean.theme}" name="theme.css" />
</h:body>
Where #{themesBean.theme} variable reffers to name of your theme.
P.S. tested in PF5
Same answer on similar question https://stackoverflow.com/a/24092773/2993327
This is what you need to do (untested, but should give you an indication how it should work)
Disable standard theme support (in web.xml):
Code:
<context-param>
<param-name>primefaces.THEME</param-name>
<param-value>none</param-value>
</context-param>
Make a managed bean (CDI or std JSF) that holds the value for the theme.
Code:
#Named #SessionScoped
public class LayoutBean
{
...
private String theme = "test";
...
public String getTheme()
{
return theme;
}
...
}
Add following tag in the head of all your pages (template)
Code:
<link rel="stylesheet" href="#{request.contextPath}/themes/{layoutBean.theme}/skin.css" />
You can find this solution on the following URL how to set a PrimeFaces theme?
In My struts2 application i have a struts2 tag checkboxlist something like this
<s:checkboxlist name="yourSelect" label="Are You Inteterested In"
list="communityList" value="defaultSelect" />
i added the list elements in my action class constuctor
view plaincopy to clipboardprint?
public CustomerAction()
{
communityList = new ArrayList<String>();
communityList.add("WebSpere Consultuing");
communityList.add("Portal Consulting");
communityList.add("SOA/BPM Consulting");
communityList.add("Content Management");
}
public CustomerAction() { communityList = new ArrayList(); communityList.add("WebSpere Consultuing"); communityList.add("Portal Consulting"); communityList.add("SOA/BPM Consulting"); communityList.add("Content Management"); }
and i can very well display it on the jsp page ,
But the problem is when i call the jsp page in the web.xml
<welcome-file-list>
<welcome-file>/pages/Customer.jsp</welcome-file>
</welcome-file-list>
list is not populating , when i request the action name from the struts.xml of the Class whose constructor has the list values then the list is populating
how do i call the action name from the web.xml as a welcome-list-file instead of typing the action name at the url .....
Create a simple JSP with an redirect.
<% response.sendRedirect("myaction.action"); %>
You could create a new welcome jsp or html file with this in its <head>:
<meta http-equiv="Refresh" CONTENT="0; URL = /project/MyAction.action"/>
This will invoke your Struts2 action, which will handle populating the ArrayList and forwarding you to your real welcome page.
This thread has some other tips that may work as well.
