Hi,
I am using Struts1.1. The development env is Websphere(WSAD5.1) on WinXP.
Here is a strange thing.
When I click on submit on a page, which used to work earlier, I get a
HTTP 500 Internal Server error.
No other link/function in the application gives me this error. The
strange thing is that this worked twice(for 5 minutes) after I added
back into web.xml the following.
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
I had removed everything but the first entry in the list. I dont know
why this error disappeared after I added it back in.???
Anyway, the error appeared again, without me having to do anything.
this appears to be the core of the error
[11/29/04 9:57:08:668 EST] 25de1e06 ActionServlet E
org.apache.struts.action.ActionServlet
javax.servlet.UnavailableException: Cannot initialize RequestProcessor
of class com.web.reqprocessor.CareRequestProcessor:
java.lang.ClassNotFoundException:
com.web.reqprocessor.CareRequestProcessor
where CareRequestProcessor is my application's custom controller.
I am attaching the log SystemOut.log , the web.xml, the
struts-config.xml(parts of it which shows the actionmapping)
I could not find anything on this error. If this is a problem of my
server not being able to find the class in its build path, why is this
error happening only for a single functionality?
Please help with your comments/suggestions.
Thankyou,
Rosemary
