[jira] Created: (WW-2995) NullPointerException on ComponentTagSupport.doStartTag using jsp:include or s:include

NullPointerException on ComponentTagSupport.doStartTag using jsp:include or s:include
-------------------------------------------------------------------------------------

                 Key: WW-2995
                 URL: https://issues.apache.org/struts/browse/WW-2995
             Project: Struts 2
          Issue Type: Bug
          Components: Plugin - Tags
    Affects Versions: 2.0.14
         Environment: Windows Vista 32-bit and Red Hat 4 WebLogic 10.3
            Reporter: Nestor Boscan
         Attachments: MyAction.rar

When using jsp:include or s:include in a JSP page the next Struts 2 tags will throw:

java.lang.NullPointerException
	at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:50)

This happens with WebLogic 10.3 but doesn't happen in OC4J 10.1.3.4.

Sam S. Wang commented on WW-2995:
---------------------------------

Problem solved!!
Struts version: 2.0.14
WebLogic: 9.2

It was caused by lacking of namespace declared in web.xml and that's required by WebLogic.
Please check your web.xml and fill in the namespaces for web-app as following:

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
..............................
..............................
..............................

This worked for me. Good luck!

Dave Newton commented on WW-2995:
---------------------------------

I don't know anything about how WebLogic deals w/ service or maintenance packs, but I know they have them, because the place I know that uses it has them and has applied them. Since this is almost certainly a WebLogic-specific issue you'll most likely need to make sure your version is up-to-date. I'll ask my friend for a maintenance pack version/release/however WL does it.

-----------------------------------

If you're refiering to the Operating System is Windows Vista Service Pack 1. But it also reproduces on Red Hat 4, so it looks it's not attached to a particular operating system. I even tried to use Sun JDK instead of JRockit and the problem persists.

---------------------------------

No, I'm referring to the WebLogic service pack, because WebLogic is where the issue is. I asked a friend and he said they'd had some issues with JSTL include (I think he meant JSP) but that it was fixed in a service pack.

---------------------------------

I don't see any source--I'm not particularly fond of running random Java code on my machine just to see what happens, and I don't have a VM installed on the box I'm running right now (and I don't have WebLogic anyway). I also have no idea what libraries you have installed with the app. Also don't know how you're accessing the page, although I'm assuming /myaction.action.

It's weird the container would get blown away, though.

The code is in the rar file. I used Struts 2.0.14 libraries. The page I'm trying to access is /myaction.action. Been trying to figure out what's the problem for two months now. I know that the problem is that when the tag library tries to get the Struts 2 dispatcher it comes null and it generates the NullPointerException.

I come from the Oracle side of things. In the last months I checked Oracle's support site to see if there was a patch but couldn't find one. So I'm testing over the 10.3 installation. And they still don't have a patch on their support site for 10.3.
