Have you taken a look at parameters in configuration results?

http://struts.apache.org/2.0.11.2/docs/parameters-in-configuration-results.h
tml

You could pass in the redirectURL from your calling web app. I've never
tried this but it seems like it would work. It's worth a shot.

Struts 2 actions are intended to be request scoped, not session scoped.
You should re-work your action to store data you wish to persist across
requests in the session, rather than storing the action itself in the
session.

L.

Well, I've put this line just below the tags <s:actionerror /> and
<s:fielderror />:

<%((ActionSupport)
ActionContext.getContext().getActionInvocation().getAction()).clearErrorsAndMessages();%>

I don't like putting Java code on JSPs and I'm sure there is a better
way to do it, but so far it's working.

Diego.

Those can safely be ignored but feel free to register a JIRA issue so
we can see if we can do something to prevent these messages to appear
in the log. One way to do it is to filter them with your logging
configuration.

hi Nils,

just want to say good job on your s2 portlet jetty-pluto plugin =)
because it boosted my productivity during my portlet development.

in fact, i've written a short tutorial for portlet project management
using struts2, spring, and your plugin =)
i have attached the tutorial here for reference.

i've successfully deployed 2 portlets (in Liferay 5.x) that used a
datasource to display tabular data.

keep up the good work!

regards,
/kits

Hi,

I'm working on struts2 + qi4j plugin. One of the feature that we want
to support is for struts 2 to understand qi4j property and
associations.
IIUC, I would need to register my own PropertyAccessor for all objects.

When I tried to do this, by declaring:
<bean type="ognl.PropertyAccessor" name="java.lang.Object"
    class="org.qi4j.library.struts2.internal.util.Qi4jPropertyAccessor"/>

This error occured:
Caused by: com.opensymphony.xwork2.inject.DependencyException:
Dependency mapping for [type=ognl.PropertyAccessor,
name='java.lang.Object'] already exists.

And if I tried to override both:
o ConfigurationManager#addContainerProvider
Make sure when container provider is an instance of
StrutsXmlConfigurationProvider, and sets
[ThrowExceptionOnDuplicateBean] property to [false]; and
o Configuration#reloadContainer and Configuration#createBootstrapContainer
Sets ContainerBuilder#setAllowDuplicates to [true]
to allow duplications, This would enable duplicate declarations for
any factory and aliases. Not just my [PropertyAccessor].

Is there a better way to do this? Ideally, I only want to allow
duplicate for [PropertyAccessor] declarations without creating my own
Qi4jFilterDispatcher, Configuration and ConfigurationManager.

Edward Yakop

If I set it to anything else, my property accessor won't be handling
all java objects
anymore.

Hi,
I'd like to overriding the default TextProvider to use my own
implementation (labels come from a database).
I have configured in my struts.properties :
struts.xworkTextProvider=fqcn of my TextProvider implementation.
But at the end it doesn't works :-(.

I have found some jira issues some says it's fixed some says no.
Is-it possible ? (maybe with an Interceptor and how ?)

Thanks in advance,
--
Olivier

Sorry for noise.
It looks overriding methods from ActionSupport (as it implements
TextProvider) helps me.

Thanks,

Assuming you have a file named "test.txt" at the root of your webapp, you can get the absolute path name to the file with the following code snippet in ur interceptor.
    ActionContext context = actionInvocation.getInvocationContext();
    HttpServletRequest request = (HttpServletRequest) context.get("com.opensymphony.xwork2.dispatcher.HttpServletRequest");
    String completeFilename = request.getSession().getServletContext().getRealPath("test.txt");

Vasyl,

The attempt is very iffy. Some things you need to know:

1) No Servlet API provides the path to your files.

2) If running in a WAR file that is never expanded, there will be no
such file directory that will exist.

3) You can use the classloader of the web context to get the root of
your web application, but that assumes #2 is false. You must be on a
file system for it to work.

I think Paul's point was that if you're deploying a WAR/EAR that won't work, hence when possible it's best to avoid such things.

It's also cleaner to get the request via ActionContext. Cleaner still by implementing ServletRequestAware as then being tied to the servlet spec is stated explicitly.

(I'm also always nervous about using a string literal to identify an attribute when there's a defined String for it already.)

If the goal is to load a file then putting it on the classpath and loading it as a resource is cleaner and safer. If it's for writing then I'd be nervous about that too; seems like it'd be a better idea to write to somewhere outside of the webapp :/

Hi
I'm working on struts2 interceptors, which inherits WebWork.
My requirement at one interceptor:

----->request------->Bread Interceptor : before invocation.invoke()
------------->Action
<------response<---Bread Interceptor : after invocation.invoke()
<------------------|

1)Interceptor will process the steps before invocation.invoke()
2)Then in action invocation Action will execute
3)After that interceptor will get executed for remaining steps

But in step 3) the response is getting dispatched to the browser,then
response is not in sync with post interceptor execution.

Please suggest me , how to make sync the response with the post interceptor
execution.

thanks

You may need to perform your post-processing inside a
PreResultListener [1], that is, just before the result is executed.

See the thread in struts-user started on 3 August 08 titled "Issue with

Hi XML

You can write your own ActionMapper.

Look:
http://struts.apache.org/2.x/docs/actionmapper.html

I used debuger and I watched DefaultActionMapper. It help me.

Hi,
We are using struts2 2.0.6 and now we have a requirement to have some Access Control into it,

That is we got some functions points and each ROLE got different access rigts
against each function, if someone login to the System the UI will be presented based on these configurations.

What I want to know is within Struts 2, How can I achieve this kind of functionality. Are there any better integration TAG libs or somthing like that.

Note : We do not have any big Application Servers as such just that apache/tomcat

Thanks

we implement this, and we create our own Interceptor, and we inject it
using Spring, and run well (with Hibernate as the Model)

take a look in the SVN of our project http://www.sf.net/projects/cimande

the package name org.blueoxygen.debus

hope this can help you to get the example

try the 1.3SDK, the ACL build inside

Hi,
I have an action class which implements preparable . It works fine but i
noticed that the prepare method inside the action class gets invoked twice
before getting to the intended method.In first invocation the variables
inside the action class are all null , However in second invocation they all
are prefilled from the page.Can anyone explain why it gets invoked twice ?.

If you implemented only prepare() method, it will be called each time
before any call to action's method of this class. If you have methods:
input() and update(), prepare() will be called before input() and
update(). If you want to call it only before input() add
prepareInput() or prepareDoInput() method [1]

It can be also issue with Ajax TabbedPanel, try to search in group archive.

Thanks Lukasz for quick reply.But the action class that has the prepare
method has four methods .

Just leave prepare() empty (you can also setup interceptor to don't
call prepare() method) and implement prepare<YourMethod>()

The salient point was that prepare() will be called before any method in the class, regardless of how many methods the class has.

If you're calling a single method (like during a typical action request) and prepare() is being called multiple times then something has gone wrong, but without more information (action configuration, interceptor stack configuration, relevant action code, etc.) it will be difficult to help.
