I am sorry, I don't think I am explaining well. My english
comprehension is still new, so I am doing a poor job. I have jsp page
login.jsp in <CATALINA_HOME>/webapps/ChargeCard (let's call it
<APP_HOME>). I have moved my servlets from
<CATALINA_HOME>/webapps/ROOT/WEB-INF/classes to
<APP_HOME>/WEB-INF/classes. So my question is twofold:
1) from my jsp, how do I invoke the servlet in it's new location?
Prior I was using:
<form method="POST" name=mainform
action="servlet/com.gcc.creditcard/CCLogin"> but that no longer works,
and it doesn't work without the servlet prefix either.
2) Once I am sucessfully able to invoke CCLogin, how do I dispatch to
my second jsp (keeping my session variables)? I think Yoav answered
this for me though - now that the servlets are in same context, I
should be able to use
RequestDispatcher rd =
getServletContext().getRequestDispatcher("/CCEntry.jsp");
But I can't test this theory until first issue is resolved. I thank
everyone (especially Yoav, who is my new java superhero) for your
patience with me! Tomcat user list is the best!
