Take a look on struts-default.xml, you have to define bean and then constant

where to set 'struts.multipart.parser' property in struts2?

2010-01-12 Thread Stephen Ince 
Hi,
  I am using struts2 version 2.1.8.1 and I am trying to set the
struts.multipart.parser property. I can't seem to set it. I have tried
every where, one place at a time.
This is what I have tried.

WEB-INF/classes/struts.xml


WEB-INF/classes/struts.properties

struts.multipart.parser=org.apache.struts2.dispatcher.multipart.JakartaMultiPartRequestx

WEB-INF/classes/loadgeneral.xml 

10240
org.apache.struts2.dispatcher.multipart.JakartaMultiPartRequestx
/.deleted


I have also tried setting 'struts.multipart.saveDir' but that is not
being set either.
I am getting the follwing warning:
INFO: Unable to find 'struts.multipart.saveDir' property setting. Defaulting to
javax.servlet.context.tempdir

Question:
  Does any have an idea of what could be the problem or where I should
set the 'struts.multipart.parser' property?
  Any help would be greatly appreciated?

Steve

Struts 1.1 EL error moving to Servlet 2.4

2010-01-12 Thread Jim Kennedy 
I've had quite a few issues with EL moving from Servlet 2.3 to 2.4 (JBOSS
4.0 to 4.2).  I have worked out my straight JSTL issues by changing my
taglib definitions, but my struts tags that use EL are not working
correctly.  This project started out using Struts 1.1 then I added the
struts-el.jar to allow for EL in my struts tags.  This all worked great
until my recent upgrade.  I get the infamous message:
 
According to TLD or attribute directive in tag file, attribute value does
not accept any expressions.
 
More specifically I get:
 
According to TLD or attribute directive in tag file, attribute arg0 does not
accept any expressions.  I get this for the following code:


The details of the above don't really matter, but it is obvious that the new
version of the servlet spec I am running does not like the use of
expressions.

The old version ran under Servlet 2.3, JSTL 1.0 and JSP 1.2

The new version runs under Servlet 2.4, JSTL 1.1 and JSP 2.0

Any advice would be great.  I'm hoping not to have to change my struts libs
as I am concerned about moving from 1.1 to 1.3.

Thanks

Distinguish between request parameters and struts.xml parameters in Struts2

 Distinguish between request parameters and struts.xml parameters in Struts2

Hi all,
  I'm trying to distinguish the parameters that come from the request from
those that come from the params defined in the struts.xml. For example, I
have the following mapping in my struts.xml


my resource
/example/Login.jsp
Menu


The call to that action will have a variable number of parameters, so I want
to distinguish between them and the parameter defined in the struts.xml. How
can I do that? In Struts 1 I was able to use the tag , and
since the action was separated from the form, there was no problem, but in
Struts2 that is no longer possible. Any ideas?

Thanks

Re: [S2] Does global exception mapping work with interceptor?

2010-01-12 Thread Gabriel Belingueres 
Is your custom interceptor _before_ the exception interceptor in your
interceptor stack? If that's the case, then the exception interceptor
is not "catching" exceptions from your interceptor because it executes
after.

Re: [S2] Iterate over sessions

2010-01-12 Thread Lukasz Lenart 
You can create a class that implements HttpSessionListener [1] and
there register active user session in some global variable (bad idea).
Or create custom interceptor that will all the time verify if given
user is locked and forward him to appropriated page.

[S2] Iterate over sessions

2010-01-12 Thread Gustavo Felisberto 
Hello All,

 

I have a Web application where I handle the logged in status with some
variable in the session. I have some actions for the Administrator where we
can control if a particular user account is locked or not. My problem is
that if a user loges in and after that the admin locks the account the user
can continue to use the application until he logs out and tries to login
again.

 

I did not want to have to go to the database each time the user performs an
action. So when the Admin locks a user I would like to iterate over all
sessions to see if that user is logged in and force a logout.

 

So my question is how can I access all created sessions?

Re: Define Global Timeout [S2]

2010-01-12 Thread Gabriel Belingueres 
I don't know if you can make this work.

IIRC, interceptor instances are created one by interceptor stack, so
the same instance is shared by all requests that go through that
stack. This makes the interceptor (at best) serialize all requests in
its wait-notify cycle. However, I think it is buggy since the notify()
can wake up any other waiting thread, not the one that created the 2
worker threads: you may assign a unique value to each interceptor call
to associate to the 2 workers for identifying who need to wake and who
need to go to sleep again.

Java monitors uses signal and continue semantics, so you need to
precede the wait with a while loop:
while (justAwakedThreadId != currentId) { wait() }

Also, I think you can safely replace the watchdog thread with just a
call to wait(milliseconds).

One last point to consider is what to do with the generated response,
you may want to implement certain logic inside a PreResultListener to
determine what to do?

Re: Define Global Timeout [S2]

2010-01-12 Thread Jorge Sousa 

Hi,

I can´t change the Tomcat, and i don´t think that change the Tomcat will 
help me to accomplish the feature that i want.


My action does several call's to a external API, and i want to ensure 
that all the call's won't exceed the time that i defined in the timeout.
Changing the Tomcat, will only works for each request, instead of the 
total time of the execution of the action.


I hope this extra information is usefull to help everyone helping me :)

Thanks.

Jorge

If you're using Tomcat via the Tomcat connector, take a look at reply

If you're not using Tomcat, I'm sure there are similar options in other app
