I've been working on some minor updates to Struts-EL, to match recent changes
to the base tag library, so I've been running through some tests. I'm using
WebLogic 8.1 for these tests.
I first noticed that the strutsel-exercise-taglib application dies with the
following stack trace:
-----------------
java.lang.NullPointerException
at org.apache.struts.util.RequestUtils.pageURL(RequestUtils.java:1591)
at org.apache.struts.util.RequestUtils.computeURL(RequestUtils.java:536)
at org.apache.struts.util.RequestUtils.computeURL(RequestUtils.java:431)
at org.apache.struts.taglib.html.LinkTag.calculateURL(LinkTag.java:495)
at org.apache.struts.taglib.html.LinkTag.doStartTag(LinkTag.java:353)
at org.apache.strutsel.taglib.html.ELLinkTag.doStartTag(ELLinkTag.java:675)
-----------------
Line 1591 is the following (after I added a couple of debugging lines):
String pagePattern = moduleConfig.getControllerConfig().getPagePattern();
I found that "moduleConfig" is null here, but I don't know why.
Before I submit a bug for this, does anyone have an idea what might be
happening here?
In addition, I also found a problem in the base "struts-exercise-taglib". The
link for the "html:link" page dies with the following stack trace:
-----------------
javax.servlet.jsp.JspException: Cannot find ActionMappings or ActionFormBeans

-----------------
I hope this isn't something that only happens in WebLogic.
