I need to upload files upto 10 MB.I used the following .In my struts.xml i configured like as follows.
<action name="doUpload" class="com.example.UploadAction">
<interceptor-ref name="fileUpload">
<param name="maximumSize">20971520</param>
</interceptor-ref>
</action>
I did not configured any where other than this.I am getting the following error.
the request was rejected because its size (2102840) exceeds the configured maximum (2097152)
Can any one suggest me what might be the reason.Thanks in advance.
Put this in your struts.xml file
<constant name="struts.multipart.maxSize" value="30000000" />
See http://struts.apache.org/2.x/docs/file-upload.html#FileUpload-AdvancedConfiguration.
Updated link -
https://struts.apache.org/core-developers/file-upload.html#file-size-limits
Also check your container configuration. Tomcat itself, for example, has a maxPostSize parameter which, if not set defaults to 2097152 (2Mb)
put this code on your strtus.xml:
<constant name="struts.multipart.maxSize" value="50000000" />
where value denotes your file size limit . if you want to extend the limit you can change the value as well . hope it helps

I'm working with a Struts 2 webapp with the following action mapping:
<action name="something_*" class="foo.whatever.MyAction" method="{1}">
<result>blah/myJsp.jsp</result>
...
</action>
So if I load the URL /something_load.action, it calls to MyAction.load(), and so on. Piece of cake. What puzzles me is that loading /something.action does work too (I guess it's invoking the execute() method). How is it possible? My action mapping is supposed to match "something_", but there is no underescore in my URL. It should give me an error! Shouldn't it?
I've double checked that there isn't another mapping for "something.action" in the struts config files. I also checked the web.xml file, just in case...
The only explanation that I can imagine is that the underscore is ignored in Struts if I use wildcard mappings. But then it would make no difference to load /something_load.action, /some_thing_lo_ad.action... and that's not true.
I'm aware that this must be a very noobish question, but I've been unable to solve the mistery, neither looking through Stackoverflow questions nor the Struts documentation.
This is the main struts.xml file:
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="false" />
<constant name="struts.freemarker.templatesCache" value="true" />
<package name="default" extends="struts-default">
<!-- interceptors ... -->
<!-- global results for error pages -->
</package>
<!-- lots of includes -->
</struts>
It appears that wildcards are matched loosely in order to support some legacy syntax. So the issue isn't with underscore but with loose matching pattern.
From the javadocs:
Patterns can optionally be matched "loosely". When the end of the pattern matches \*[^*]\*$ (wildcard, no wildcard, wildcard), if the pattern fails, it is also matched as if the last two characters didn't exist. The goal is to support the legacy "*!*" syntax, where the "!*" is optional.
In struts2, is it possible to have an action name with a space?
I'm using the RegexPatternMatcher
<constant name="struts.patternMatcher" value="regex"/>
<constant name="struts.enable.SlashesInActionNames" value="true"/>
<constant name="struts.mapper.alwaysSelectFullNamespace" value="false"/>
My action is defined as
<action name="/users/{username}"
method="execute"
class="com.test.UserAction">
<result name="success" type="tiles">.test.user</result>
</action>
When I try a url like, http://localhost:8080/users/a%20space
The a%20space is set as aspace in the model. The %20 is not escaped and is just removed. I've also tried http://localhost:8080/users/a+space and the same thing happens.
Environment
Struts2 version, 2.3.15.1
You can allow spaces in action names by setting the parameter in the struts configuration,
struts.allowed.action.names
The default is
[a-zA-Z0-9._!/\-]*
The DefaultActionMapper uses this regex to validate the action name. If it doesn't match, it'll try to clean it up.
So modifying the setting to
<constant name="struts.allowed.action.names" value="[ a-zA-Z0-9._!/\-]*"/>
allows spaces
I have all the jsp pages (ex: index.jsp) in the WebContent folder and my application is working smoothly.
Now, I created a folder "pages" inside WebContent, where I transferred all my jsp pages.
And I added the following line inside the <struts> tags:
<constant name="struts.convention.result.path" value="/pages" />
But still, its not searching for jsp inside the "pages" folder.
I am getting:
HTTP Status 404 - /MyApplicationName/index.jsp
Where am I doing a mistake?
EDIT: The current structure of my application is as follows:
The welcome page is an action instead of a jsp page. The result page of this action is index.jsp. This action populates the dropdown menu and some other fields in index.jsp. Now, I want to keep index.jsp along with other jsp pages in the folder "WebContent/pages". I have over 30 jsp pages in my application, and I don't want to mention the full path of every jsp in the result-tag. Thats why I want to make use of the struts2 constant "struts.convention.result.path"
My question is, why the code I have mentioned above is not working?
Accessing index.jsp directly bypasses all S2 request handling.
There's no S2 or S2 Convention plugin involved, you're just accessing a JSP page.
If index.jsp is first page of your application then you need to change its path to /pages/index.jsp in <welcome-file> tag of web.xml. And for rest I agree with #Dave Newton :)
Probably your mistake was in struts.xml.
When you create a new-Folder under web-content make with the same name (folder-name) of
xml file under src and include it in struts.xml file it will work fine.
For eg: suppose you created example folder under web-content, now create example.xml file
under src folder and in struts.xml file include example.xml
example.xml:
<struts>
<package name="example" namespace="/example" extends="default">
<action name="your action name" class="your class" method="your method">
</action>
</package>
</struts>
struts.xml:
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="false" />
<action name="" class="" method="">
</action>
</package>
<include file="example.xml"/>
I have struts.devMode=true in my struts.properties. Which will cause resource bundle to reload each time. But every time when it try to reload it throws exception below. My application is running on websphere 7. Any help will be appriciated.
com.opensymphony.xwork2.util.logging.commons.CommonsLogger error Could not reload resource bundles
java.lang.NoSuchFieldException: cacheList
You can't work with Struts 2 in devMode and Websphere. There isn't many information on the Internet (in French) but what I can understand with my limited French knowledge is that you have to put the server with production settings.
I mean that your struts.xml must be like this to make Struts2 work on Websphere:
<struts>
<constant name="struts.devMode" value="false" />
<constant name="struts.i18n.reload" value="false" />
<constant name="struts.configuration.xml.reload" value="false" />
...
</struts>
The reason that why is this happening is not very clear. The blog explains that maybe is for a different JVM implementation by IBM and maybe it differs in the implementation of the ResourceBundle class that has no private field cacheList and then raises an error when it reloads the i18n labels.
the follow solution worked for me in Tomcat 7 and WebSphere Application Server 7.
LocalizedTextUtil.reset();
ResourceBundle.clearCache(LocalizedTextUtil.class.getClassLoader());
This will clear the ResourceBundle cache.
*devMode and i18n.reload must be false.

In struts2 I am writing an app where I need to make sure that the url redirection works the same whether or not there is a trailing slash at the end.
E.g. example.com/app should behave same way as if user entered example.com/app/. Currently I changed mapping in struts.xml like so -
<struts>
<package name="default" namespace="/" extends="secure">
<interceptors> ... <interceptors>
<action name="app">
<result type="redirectAction">/app/</result>
</action>
</package>
</struts>
and
<struts>
<package name="app" namespace="/app" extends="secure">
<interceptors> ... <interceptors>
<action name="" class="com.example.action.app.LoginAction" method="display">
<interceptor-ref name="store">
<param name="operationMode">RETRIEVE</param>
</interceptor-ref>
<interceptor-ref name="basic" />
<result type="redirectAction">home</result>
<result name="display">/jsp/base/content/login/loginForm.jsp</result>
</action>
</package>
</struts>
But this seems hackish since if I go to example.com/app it will show example.com//app/.html in the URL.
Any help appreciated.
Answer was derived in comments under the answer.
Quaternion:
Personally I would write all my urls with out the trailing slash...
and then I would use something external to the application to rewrite
urls as appropriate, perhaps iptables could determine if there is a
trailing slash and if so always strip it.
Mohana Rao SV:
As suggested above follow without tailing slash. And override
StrutsPrepareAndExecuteFilter one of the filter job is from the url it
has to identify the namespace and action name and invoke respective
action. So here remove tailing slash from url.
Quaternion:
In namespace "/" you have an action called app. That is all there is
to it to invoke CONTEXT_ROOT/app (that is what struts2 expects), you
don't ever expect to see a "/" on the end of the url, so you want to
find a method that parses the url before struts2 resolves the mapping.
What you have described only requires something to remove a trailing
"/" if it exists. I'd look to iptables because I've used it before or
some other url rewriter... Mahana would keep it all part of the web
app and use a filter, methods differ but the effect is the same.
