My humble guess is that both Jsr168Dispatcher and Dispatcher are cleaning the context; so the last one being called gets a null reference because the previous dispatcher already performed the clean.
As a side note, if you are not able to depoy on jboss, please remove the commons-logging jar from the sample portlet war file.

Wes Wannemacher commented on WW-2509:
-------------------------------------
Which version of the portlet plugin are you using? I couldn't seem to get the line numbers in your stack trace to match up with the code... Plus, I don't see a portlet plugin tagged for version 2.0.11 -

[jira] Commented: (WW-2509) Sample portlet application throws NPE
when undeploying from Jboss
Posted by "Miguel Ping (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/struts/browse/WW-2509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43456#action_43456 ]
Miguel Ping commented on WW-2509:
---------------------------------
Thanks for the reply, guys.
I am also using the portlet support on my own apps, and unfurtonately I use both Jsr168Dispatcher and FilterDispatcher. I use them both because I use the jsr dispatcher for 'plain' portlet dispatching and use the filter dispatcher for servlet dispatching; I intermix both because the servlet is used to support regular ajax calls that come from the portlet.
Is it possible to reopen this bug, or the jsr dispatcher is not supposed to be used in conjunction with the filter dispatcher?

[jira] Commented: (WW-2509) Sample portlet application throws NPE
when undeploying from Jboss
Posted by "Nils-Helge Garli (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/struts/browse/WW-2509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43432#action_43432 ]
Nils-Helge Garli commented on WW-2509:
--------------------------------------
If I have the correct code in my IDE, it looks like the ThreadLocal (the actual ThreadLocal, not it's contained value) in the Dispatcher (line 268: http://svn.apache.org/viewvc/struts/struts2/tags/STRUTS_2_0_11/core/src/main/java/org/apache/struts2/dispatcher/Dispatcher.java?view=annotate) has gone null?.... I have no idea how that's possible (am I looking at the wrong place??)

[jira] Commented: (WW-2509) Sample portlet application throws NPE
when undeploying from Jboss
Posted by "Miguel Ping (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/struts/browse/WW-2509?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=43393#action_43393 ]
Miguel Ping commented on WW-2509:
---------------------------------
I downloaded the "example applications" zip from 2.0.11 release: http://struts.apache.org/download.cgi#struts210 and deployed the portlet application that comes in the apps zip file. By the way, I had to remove the commons-logging jar (commons-logging-1.0.4.jar) file from the portlet application's war file because it was conflicting with my jboss app:
10:36:08,789 ERROR [STDERR] Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy. You have more than one version of 'org.apache.commons.logging.Log' visible, which is not allowed. (Caused by org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy. You have more than one version of 'org.apache.commons.logging.Log' visible, which is not allowed.) (Caused by org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy. You have more than one version of 'org.apache.commons.logging.Log' visible, which is not allowed. (Caused by org.apache.commons.logging.LogConfigurationException: Invalid class loader hierarchy. You have more than one version of 'org.apache.commons.logging.Log' visible, which is not allowed.)).
But you're right, there's no portlet plugin tagged for 2.0.11.
I'm also using struts2+portlet plugin for another application, and the failure to undeploy is causing me a PermGen after 3 or 4 deploys, because each time I try to undeploy an application, I'm guessing the NPE is preventing the app from being fully destroyed.

[jira] Commented: (WW-2509) Sample portlet application throws NPE
when undeploying from Jboss
Posted by "Nils-Helge Garli (JIRA)" <ji...@apache.org>.

Nils-Helge Garli commented on WW-2509:
--------------------------------------
It appears that the cleanup happens twice, once for the FilterDispatcher and once for the Jsr168Dispatcher. The second time around, the ThreadLocal is null. I have no idea why the thread local is null the second time cleanup is invoked, but the simple solution is to remove the filterdispatcher from the sample app, as it's not used anymore.

-------------------------------------
I didn't check in the 'apps,' I'll pull that code down and see if I can fix the NPE tonight.

> My humble guess is that both Jsr168Dispatcher and Dispatcher are cleaning the context; so the last one being called gets a null reference because the previous dispatcher already performed the clean.
> As a side note, if you are not able to depoy on jboss, please remove the commons-logging jar from the sample portlet war file.
