Look in your JRun/lib/ext directory and check if you have jaxp.jar and
parser.jar. Try removing them if you do. Also make sure that the struts jar
and tlds are accessible to JRun.

Subject: At wits end, questions JRun, Oracle9ias
Strutsters,
I've been playing around with struts on my local machine here at work
under Tomcat and everything is fine. In another local environment I've
been using JRun for some applications and I'd like to get the sample
app I was working under Tomcat to work under JRun. I'm not having any
luck. I've been searching these archives and whatever I could find but
I'm still stuck.
Here's the deal. I have a really really watered down basic app in a
directory called 'utilities' in the tomcat webapps folder. I now took
this whole directory and copied it into the default path for where I
have other JRun apps. ( I configured JRun to point to this new
application and even configured the servlet mapping). If I try to go
right to the page 'payrollChangeForm.jsp' I get an error that others
have gotten (not necessarily with JRun):
Exception thrown processing JSP page.
javax.servlet.jsp.JspException: Cannot find ActionMappings or
ActionFormBeans collection
at org.apache.struts.taglib.html.FormTag.lookup(FormTag.java:781)
at org.apache.struts.taglib.html.FormTag.doStartTag(FormTag.java:481
....{cut}...
Now, I'm not sure what cause this error since the same files are
working fine under Tomcat. Another thing messed up which might help
some of you debug is I also have an index page with a simple link on
it that calls the action :
<action path="/payrollChanges"
forward="/formsStruts/test.jsp">
</action>
When this link is hit, I get a nice 500 Internal Error page with:
null
java.lang.NoSuchMethodError
at org.apache.commons.digester.Digester.parse(Digester.java:859)
at
org.apache.struts.action.ActionServlet.initMapping(ActionServlet.java:1274)
at
org.apache.struts.action.ActionServlet.init(ActionServlet.java:461)
What else do I need to get this running successfully under JRun? The
installation instructions with Struts mention the taglib issues but I
don't think this is really related to that. Couple comments: JRun is
pointing to the directory for this application on another network
directory. This means my local classpath that points to some XML xerces
stuff I have on my local classpath won't be valid so I put the
following files in my applications lib directory xmlParserAPIs.jar and
xercesImpl.jar. Somehow I think this is a parser issue or something because
if I
remove this file and then click on the link I'll get:
org/xml/sax/helpers/DefaultHandler
java.lang.NoClassDefFoundError: org/xml/sax/helpers/DefaultHandler
at java.lang.ClassLoader.defineClass0(Native Method)
I'm just guessing here but if the parsing isn't taking place correctly
that might explain the first problem of when I try to go straight to
the form.jsp page and get the "Cannot find ActionMappings or
ActionFormBean collections' error, since maybe it can't parse the
struts-config.xml?
Any ideas what is wrong? I'm also concerned because I want to push for
using struts here at work but I know they'll have issues if it's going
to be hard to configure it to get it to work under Oracle9ias as well.
Are struts apps easy to configure under Oracle9ias as well? I didn't
think I'd have this problem with JRun so once I tackle that hurdle I
hope tackling the next one won't be as bad.
Thanks for any help.

take my little nephew to Disneyland, but instead I drove him to an old
burned-out warehouse. 'Oh, no,' I said. 'Disneyland burned down.' He
cried and cried, but I think that deep down, he thought it was a
pretty good joke. I started to drive over to the real Disneyland, but
it was getting pretty late."
