Rest Plugin + IndexController and disabling content types
Hi All, I have 2 questions regarding the struts-rest plugin ( 2.1.3-snapshot) 1) How can I write a controller that will handle the request on / ( i.e http://www.myhost.com )? 2) As I understand, the rest plugin by default handles XML and JSON extensions too ( http://struts.apache.org/2.x/docs/rest-plugin.html ) . Is there a way to disable these extensions ? ( Other than overriding struts.rest.handlerOverride.EXTENSION and providing a dummy implementation ) Thanks! -- View this message in context: http://www.nabble.com/Rest-Plugin-%2B-IndexController-and-disabling-content-types-tp19235492p19235492.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Result Annotations
Hi,
I am using Result annotations in the following manner ( static way )
@Results({
@Result(name = index, value = /jsp/en_US/help.jsp)
})
How can I pass a dynamic value to the result annotation, so that I can
achieve something like this
@Results({
@Result(name = index, value = /jsp/${locale}/help.jsp),
@Result(name = show, value = ${show} )
})
public class HelpController {
private String locale;
private String show;
...
}
Thanks!

By either (a) providing getLocale()/getShow() methods or making
locale/show public.
The other response saying it wasn't possible is incorrect; while it's true
that the annotations are scanned on startup, the value is evaluated at
runtime. See [1] for more information; annotations share the same ability.

Re: Struts 2 Rest + Prevent Session creation
Found the issue. I had missed adding %@ page contentType=text/html; charset=UTF-8 session=false pageEncoding=UTF-8% in the JSP page ( by default session is true ). Now no session is created ( and so no JSESSIONID cookie is set ) Thanks! Jeromy Evans - Blue Sky Minds wrote: rakeshxp wrote: But this does not seem to work.

Struts 2 + Rest URLs
Hi All, I am migrating from struts 2.0.10 to 2.1.2 ( for need of restful URLs). Could someone help me understand the following ? 1) Is it better to use Annotations or Codebehind for Restful URLs? ( I some how like the annotations more than assuming some standard for resources) 2) I am stuck at running the restful URLs using codebehind plugin. Here are the details: In web.xml, I have actionPackages = com.struts.example.action and I have the following package struture: com.struts.example.action - No files com.struts.example.action.account - AccountController com.struts.example.action.help - HelpController expecting that, I will get the following URLs: http://localhost:8080/myapp/account http://localhost:8080/myapp/help But this does not work. Could someone help me in figure out what is happening ? Going forward, I wanted URLs of the following format http://localhost:8080/myapp/account http://localhost:8080/myapp/account/logout http://localhost:8080/myapp/help http://localhost:8080/myapp/displayname ( so if it is not account or help, then it would be a displayname and hence I want to process it specifically ).

Re: Struts 2 + Rest URLs
Excellent. Thanks! So now, I have the following
com.struts.example.action.AccountController
com.struts.example.action.account.LogoutController
When I hit, http://localhost:8080/myapp/account/logout , then I get the
following exception
No result defined for action
com.struts.example.action.account.LogoutController and result index
The LogoutController looks like this:
public HttpHeaders index() {
return new DefaultHttpHeaders(index).disableCaching();
}
I have a logout-index.jsp directly under the webapp folder ( along with
account-show.jsp, help-show.jsp etc ). So is it the proper name structure ?
Also,
1) How to specify the location of the JSPs ?
I wanted to have custom folders like this
i18n/en_US/help/index.jsp
i18n/en_US/help/show.jsp
i18n/en_US/account/show.jsp
i18n/en_US/account/logout.jsp etc
So that I can problematically serve the appropriate locale JSPs ( When using
struts 2.0.10, in the action XML, I was using something like this result
name=success/jsp/i18n/${userLocale}/account/show.jsp/result )
2) The reason I wanted /displayname is something like this
http://localhost/myapp/help - help pages
some more static pages
anything which does not match the above, could potentially be a profile page
which has the url http://localhost/myapp/username. So I wanted something
like catch all , so that I can check if it happens to be a username.
3) Just curious, when running the above code, while tomcat was starting, I
was getting
class:class com.struts.example.action.AccountController parent:null
current:com.struts.example.action.
class:class com.struts.example.action.account.LogoutController parent:null
current:com.struts.example.action.account
what does parent property mean ?
Thanks!

This is a approach is fine. The annotations are a feature of CodeBehind
in 2.1 (used by CodeBehind to create the configuration)
Note that CodeBehind will be replaced by the ConventionPlugin in 2.2ish
but the annotations won't need to change (much...).
2) I am stuck at running the restful URLs using codebehind plugin. Here
are
the details:
In web.xml, I have actionPackages = com.struts.example.action
and I have the following package struture:
com.struts.example.action - No files
com.struts.example.action.account - AccountController
com.struts.example.action.help - HelpController
expecting that, I will get the following URLs:
http://localhost:8080/myapp/account
Close, but not quite right. It works like this:
com.struts.example.action.AccountController will be at
http://localhost:8080/myapp/account
com.struts.example.action.account.AccountController will be at
http://localhost:8080/myapp/account/account
http://localhost:8080/myapp/help
But this does not work. Could someone help me in figure out what is
happening ? Going forward, I wanted URLs of the following format
http://localhost:8080/myapp/account
http://localhost:8080/myapp/account/logout
http://localhost:8080/myapp/help
http://localhost:8080/myapp/displayname ( so if it is not account or
help, then it would be a displayname and hence I want to process it
specifically ).
CodeBehind itself doesn't include any support for index actions, so you
have to set this as follows:
com.struts.example.action.AccountController -
http://localhost:8080/myapp/account
com.struts.example.action.account.LogoutController -
http://localhost:8080/myapp/account/logout
com.struts.example.action.HelpController -
http://localhost:8080/myapp/help
Not sure what you mean with display need. You probably need this:
com.struts.example.action.DisplayController -
http://localhost:8080/myapp/display/displayname
Where displayname will be set as an ID for the DisplayController
Otherwise you'll need to customize the actionmapper a little.
Hope that helps.

Re: Struts 2 + Rest URLs
I think I am beginning to understand this plugin :) One issue that I am stuck at is that, assuming I have only 1 class com.struts.example.action.AccountController , then http://localhost:8080/myapp/account and http://localhost:8080/myapp/account/1 ( maps to show ) works. But the moment I have a sub controller com.struts.example.action.account.LogoutController , then http://localhost:8080/myapp/account/1 == # There is no Action mapped for namespace /account and action name 1. ( though http://localhost:8080/myapp/account and http://localhost:8080/myapp/account/logout still works ) Thanks!

Yes. The CodeBehind plugin checks for the presence of the annotation when generating the namespace and gives precedence to the annotation. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- View this message in context: http://www.nabble.com/Struts-2-%2B-Rest-URLs-tp19179856p19183626.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Struts 2 Rest + Prevent Session creation
Creating a new post for a new query on struts 2 rest plugin. In my current app ( built on struts 2.0.10), I have a custom interceptor stack ( which is set as default-interceptor-ref ). the code looks like this: package name=mydefault extends=struts-default namespace=/ interceptor-stack name=myStack interceptor-ref name=exception true WARN /interceptor-ref interceptor-ref name=servletConfig / interceptor-ref name=params / interceptor-ref name=conversionError / /interceptor-stack /interceptors default-interceptor-ref name=myStack/ /package This custom stack prevent any http session from being created ( and hence no JSESSIONID cookie is created). I am trying to simulate the same for the newer code that I am writing ( based on struts 2.1.2 and rest plugin). I have the following entry in struts.xml constant name=struts.codebehind.defaultPackage value=mydefault / constant name=struts.configuration.xml.reload value=true / constant name=struts.configuration.classpath.defaultParentPackage value=mydefault / package name=mydefault extends=rest-default namespace=/ interceptor-stack name=myStack interceptor-ref name=exception true WARN /interceptor-ref interceptor-ref name=servletConfig / interceptor-ref name=params / interceptor-ref name=conversionError / /interceptor-stack /interceptors default-interceptor-ref name=myStack/ /package But this does not seem to work. When I hit any restful URL, then there is a JSESSIONID cookie being set. Could someone point out what is wrong with the above config ?

Struts2 + Profiling
Hello Everyone, I am using Struts 2.0.9. I want to disable profiling for my application and have the following properties configured to set so In Struts.xml constant name=struts.devMode value=false / The interceptors in my stack are interceptor-ref name=exception / interceptor-ref name=servletConfig / interceptor-ref name=prepare / interceptor-ref name=params / interceptor-ref name=conversionError / The problem is when I was profiling my application using JProfiler, I could see lot of calls to com.opensymphony.xwork2.util.profiling.UtilTimerStack.profile in the call tree. This is weired as I hoped the profiler is disabled due to devMode=false and not having profile interceptor in my stack. Could any one help me understand why I am seeing so many calls to the UtilTimerStack.profile when I have disabled profiler ?

Re: Struts 2 URL parameters lost - final status

JBL wrote: Final answer: we implemented a custom ActionMapper that handles a URL string that doesn't involve a ? to separate the query parameters. Stuck a reference to it in struts.properties: struts.mapper.class=mypackage.MyActionMapper Building a new ActionMapper isn't terribly difficult. It helps to define your expected URLs with a regular expression, then use a precompiled pattern. Ours looks something like: private static String NAMESPACE_REGEX = ...; private static String ACTION_REGEX = ...; private static String METHOD_REGEX = ...; private static String PARAMS_REGEX = ...; private static String URI_REGEX = (concatenate the four above) private static Pattern URI_PATTERN = Pattern.compile(URI_REGEX); Then, in getMapping(), pull out the URI (similar to DefaultActionMapper) and call Matcher m = URI_PATTERN.matcher(uri); If you get a match, create a new ActionMapping and set its components based on the matching groups: mapping.setNamespace(m.group(1)); mapping.setName(m.group(1)); etc. You can parse the parameter section and build a map to pass to mapping.setParams(). Using a precompiled pattern may or may not be the most efficient possible solution, but it helps you define exactly what URIs you expect. I recommend throwing a bunch of possibilities at it in your unit test code with various components present and missing. If you're a little unsure about regular expressions, build some unit tests for those, too. Sun has a decent write-up in their Java documentation: http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/Pattern.html Especially read the Groups and Capturing section, it's a handy tool to have in your portfolio. We may yet discover why we couldn't get query parameters, but this works for now.

Struts2 + Dynamic Forms + File Upload
Hi,
I am trying to create a form which would have dynamic number of file tag (
this would be created by the JS ). I am looking for a way to do so in
struts.
I have created the following class
public class FileDetails {
private File file;
private String contentType;
private String filename;
public void setUpload(File file) {
this.file = file;
}
public void setUploadContentType(String contentType) {
this.contentType = contentType;
}
public void setUploadFileName(String filename) {
this.filename = filename;
}
}
And in my action class I am trying to do
private ListFileDetails beanList = new ArrayListFileDetails();
public ListFileDetails getBeanList() {
return beanList;
}
public void setBeanList(ListFileDetails beanList) {
this.beanList = beanList;
}
And in the JSP,
s:form namespace=/xyz action=doUpload method=post
enctype=multipart/form-data
s:file name=beanList(0).upload value=%{value} /
s:file name=beanList(1).upload value=%{value} /
s:submit/
/s:form
Above method does work as it results in lot of OGNL errors like
[ERROR] XWorkMethodAccessor - An unexpected exception occurred
ognl.OgnlException: Error getting property descriptor:
nullognl.OgnlException: E
rror getting property descriptor: null

at
com.opensymphony.xwork2.util.XWorkMethodAccessor.callMethod(XWorkMethodAccessor.java:61)
Could any one suggest a solution to my problem ?
