i want to embed a xml file to a resource file in my project,whenever i need the file i must get it from resource and use it,how to do this and i want to modify the contents of the xml file depending upon my requirements.how to do this
If you add the XML file to a Visual Studio project and, in the Property window for it, select Build Action: Embedded resource, the file will be embedded into the build output artifact for that project.
To access it from code, use something like:
string resourceName = "Namespace.Prefix.FileName.xml";
Assembly someAssembly = LoadYourAssemblyContainingTheResource();
XmlDocument xml = new XmlDocument();
using (Stream resourceStream = someAssembly.GetManifestResourceStream(resourceName))
{
xml.Load(resourceStream);
}
// The embedded XML resource is now available in: xml
If the resource you're loading is embedded in your own assembly, you can do something like Assembly.GetExecutingAssembly() to achieve what I listed as LoadYourAssemblyContainingTheResource() above, or possibly typeof(SomeTypeInYourResourceAssembly).Assembly
It's unclear what you mean by "want to modify the contents" - you cannot modify the resource inside the assembly at run-time, but whenever you change the XML file and recompile, the new version will be embedded.

I am trying to create HTML files using XSLT, I have used xml file and xsl files to create HTML file. Here some other xsl files which are located in same location are included in xsl file by using <xsl:include href="temp.xsl"/>.
Here Xsl files are located in "D:/XSL_Folder/" path.
I am running Main.java file which is located in D:/Workspace/Webapp_Project/ path.
When i try to create HTML files by using passing "D:/XSL_Folder/root.xsl" and "D:/XML_Folder/data.xml" files to Main.java as arguments, I am getting following error while creating Templates.
Templates lTemplates = TransformerFactory.newInstance().newTemplates(new StreamSource(new FileInputStream(lFileXSL)));
ERROR: 'D:\Workspace\Webapp_Project\temp.xsl (The system cannot find the file specified)'
FATAL ERROR: 'Could not compile stylesheet'
12:20:07 ERROR f.s.t.v.v2.dao.impl.DocUnitDaoImpl - Error while creating a new XslTransformerGetter. The path to the XSL may be wrong.
javax.xml.transform.TransformerConfigurationException: Could not compile stylesheet
at com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl.newTemplates(TransformerFactoryImpl.java:885) ~[na:1.7.0_13]
In error report we can see that parser is checking included xsl file in project path (D:\Workspace\Webapp_Project), not in the path where root.xsl file is located (D:/XSL_Folder/).
Can anyone suggest me why parser searching xsl file in project folder in the path where root.xsl file is located and how to fix this problem?
Code I'm using to create HTML file by using XSL and XML file :
public static void simpleTransform(InputStream lXmlFileStream, File lXSLFile,
StreamResult lHtmlResult, Map<String, String> lArguments) {
TransformerFactory tFactory = TransformerFactory.newInstance();
try {
Transformer transformer =
tFactory.newTransformer(new StreamSource(lXSLFile));
for (Entry<String, String> lEntrie : lArguments.entrySet()) {
transformer.setParameter(lEntrie.getKey(), lEntrie.getValue());
}
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
transformer.transform(new StreamSource(lXmlFileStream), lHtmlResult);
}
catch (Exception e) {
e.printStackTrace();
}
}
You have tagged the question "saxon", and you have said you are using XSLT 2.0, but the error messages show that you are using Xalan. If you specifically want to use Saxon then the best way is to avoid using the JAXP classpath search and instantiate Saxon directly - in place of TransformerFactory.newInstance(), use new net.sf.saxon.TransformerFactory().
Supplying a File as the argument to StreamSource ought to be OK; but I would like to see how the File lXSLFile object is created. My suspicion would be that you have done something like new File ("root.xsl") and it has been resolved relative to the current directory.
You may try to use <xsl:include href="resolve-uri('temp.xsl')"/> instead of <xsl:include href="temp.xsl"/> to avoid this problem.
I want to read file from "res" folder on blackberry. The file that i used is a file javascript.
I used this code InputStream in = classs.getResourceAsStream("file.js");. But i get "could not find this path" and I use also
String srcFile = "/res/ressourcesWeb/file.js";
FileConnection srcConn = (FileConnection) Connector.open(srcFile, Connector.READ);
InputStream in = srcConn.openInputStream();
but i got an exception.
Can any one help me to read the file and give me the right path that should I use?
Your res folder has to be inside src folder to be accessed from your code.
src folder is the root folder of your project package. And all folders outside of src folder are invisible for the code at runtime.
Check this post for more details: Blackberry runtime error: FRIDG: could not find img/logo.png
There's file location principle described.
You actually do not need to put your resources under the src folder for them to be accessible from your code.
That is one way to do it, but I don't think it's the best way. Files under the src folder should really be source code, not images, or other resources. For JavaScript resources, it's debatable whether those should be under src or not. Most projects I've seen have used the src folder for only Java source code.
In any case, if you would like to keep your file (or other resources, like images) outside the src folder, you can do so. The BlackBerry plugin for Eclipse actually sets it up like this by default, when you create a new project. There is a res folder at the top level, next to (not under) src.
If you have
src\
src\com\mycompany\myapp\
res\
res\resourcesWeb\
res\resourcesWeb\file.js
Then, you can open the file like this:
String jsPath = "/resourcesWeb/file.js";
InputStream input = getClass().getResourceAsStream(jsPath);
byte [] content = IOUtilities.streamToBytes(input);
String contentAsString = new String(content);
P.S. You also can probably do this:
String jsPath = "/file.js";
InputStream input = getClass().getResourceAsStream(jsPath);
and not specify the path to the resource. Obviously, this will only work if there are no naming conflicts in your resource folders (e.g. you don't have /res/resourcesWeb/file.js and also /res/otherPath/file.js)
I have an .il file which I can compile without any problems. I can strong name it and so without any issues. But I am not able to set the file version via the attribute as I would expect it. How can I set the FileVersion for an assembly when using ilasm?
If I do a round trip I get always a .res file which does contain only binary data which is not readable. What is inside this res file and can I edit it?
The code does not work
.assembly myAssembly
{
.custom instance void [mscorlib]System.Reflection.AssemblyFileVersionAttribute::.ctor(string) = { string('1.2.3.4') }
The issue can be solved by using the .res file. It is not sufficient to do a round trip with ildasm and ilasm. The IL file does not reference the .res file. I had to add it to the ilasm call manually. The data in the res file seemed to contain the infos which are written into the PE header which is ok for me.
The final command line needed was
ilasm test.il /dll /res:test.res
I still do not know what exactly is inside the res file but I can exhange it with the meta data information of any other assemlby that I create manually and then decompile it to replace the metadata of the original assembly as I need.
It seems not many people are doing such stuff.
I have multimodule project
Project
|--src
|-JavaFile.java
Web-Project
|-Web-Content
|-images
| |-logo.PNG
|-pages
|-WEB-INF
regular java module - contains src with all java files
dynamic web project module - contains all web related stuff
eventually regular java module goes as a jar file in dynamic web module in lib folder
Problem
java file after compilation looks for an image file in c:\ibm\sdp\server completepath\logo.png rather in context. File is defined in java file as below for iText:
Image logo = Image.getInstance("/images/logo.PNG");
Please suggest how can I change my java file to refer to image. I am not allowed to change my project structure.
You need to use ServletContext#getResource() or, better, getResourceAsStream() for that. It returns an URL respectively an InputStream of the resource in the web content.
InputStream input = getServletContext().getResourceAsStream("/images/logo.PNG");
// ...
This way you're not dependent on where (and how!) the webapp is been deployed. Relying on absolute disk file system paths would only end up in portability headache.
See also:
getResourceAsStream() vs FileInputStream
Update: as per the comments, you seem to be using iText (you should have clarified that a bit more in the question, I edited it). You can then use the Image#getInstance() method which takes an URL:
URL url = getServletContext().getResource("/images/logo.PNG");
Image image = Image.getInstance(url);
// ...
Update 2: as per the comments, you turn out to be sitting in the JSF context (you should have clarified that as well in the question). You should use ExternalContext#getResource() instead to get the URL:
URL url = FacesContext.getCurrentInstance().getExternalContext().getResource("/images/logo.PNG");
Image image = Image.getInstance(url);
// ...
How can I programmatically add files to a TFS project that have code behind files. I can say the following to add files. That will only add single files to a project and not the file plus the code behind file. I'm trying to add a resource file and it's code behind that were dynamically generated to a TFS project.
workspace.PendAdd(filesWithPathToEdit, true);
I had to put it in a T4 template to get access to the current Visual Studio DTE otherwise it would randomly work if I tried it outside of a t4. You can use the DTE to get a list of projects from a solution then add a ProjectItem and it contains ProjectItems so you can add your code behind there. ResxContainer is a custom class to just contain all information about my resx file i needed.
EnvDTE.DTE dte = (EnvDTE.DTE)HostServiceProvider.GetService(typeof(EnvDTE.DTE));
//dte = (EnvDTE.DTE) hostServiceProvider.GetService(typeof(EnvDTE.DTE));
//dte = (EnvDTE80.DTE2)Marshal.GetActiveObject("VisualStudio.DTE");
Projects projects = dte.Solution.Projects;
if (projects.Count > 0)
{
IEnumerator enumer = ((IEnumerable)projects).GetEnumerator();
while (enumer.MoveNext())
{
Project proj = (Project)enumer.Current;
if (proj.Name == projectName)
{
foreach (ResxContainer res in items)
{
ProjectItem item = proj.ProjectItems.AddFromFile(res.ResxPath);
item.ProjectItems.AddFromFile(res.CodeBehindPath);
}
}
}
There's no way for it to automatically know if a file depends on another. However, you can decide on your own which files will typically have a code behind file associated with them and add them yourself.
For example:
If you begin to add a file with an .aspx extension, then those files, as we know, typically have a code behind file. That code behind file, we can assume, has the same file name, with .cs appended. So, if we have "Default.aspx", then we can safely assume that there will be a "Default.aspx.cs" and that they are dependent on each other, so we should add both.
The same thing goes with .xaml and .xaml.cs files.
