Hi,
I am trying to use Struts and have not been able to make it work in my
environment. I am running Visual Age for Java 3.5.3 (JSP 1.1 & Servlet
2.2). I followed the instructions for setup and have double checked them.
I am getting the following error in my browser when I invoke a jsp. I was
hoping someone might have a clue as to where the problem might be OR where
I might look to find more info.
Error 500
An error has occured while processing
request:http://localhost:8080/employeelist/jsp/employeeSearch.jsp
Message: Server caught unhandled exception from servlet [jsp]: cant remove Attributes
from request scope
Target Servlet: jsp
StackTrace:
--------------------------------------------------------------------------------
Root Error-1: cant remove Attributes from request scope
java.lang.IllegalArgumentException: cant remove Attributes from request scope
java.lang.Throwable(java.lang.String)
java.lang.Exception(java.lang.String)
java.lang.RuntimeException(java.lang.String)
java.lang.IllegalArgumentException(java.lang.String)
void org.apache.jasper.runtime.PageContextImpl.removeAttribute(java.lang.String,
int)
int org.apache.struts.taglib.html.FormTag.doEndTag()
void jsp._employeeSearch_xjsp._jspService(javax.servlet.http.HttpServletRequest,
javax.servlet.http.HttpServletResponse)
.....(more)....
I've traced the generated java code for the jsp and the exception happens at the
doEndTag() method (as the stack trace shows above) for the
</html:form> tag.
The simple jsp I'm invoking is shown below.
<%@taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<html:html locale="false">
<html:errors/>
<html:form action="processEmployeeSearch.do">
Name: <html:text property="name"/><BR>
Find All: <html:checkbox property="findAll"/><BR>
<html:submit/>
</html:form>
<A HREF="http://localhost:8080/employeelist/jsp/employeeEdit.jsp";>Add an Employee</A>
</html:html>
The action servlet shouldn't even be invoked yet since I'm calling the jsp
and it won't even display. I'm sure it's something simple but I can't find
it. Does this mean anything to anyone? I've been struggling with this for
a while and am out of ideas.
Thanks,
Ken
