Beginner question: form bean executing but action class not
Hi,
I have gotten my first extremely simple (2 web pages) Struts application
working and am slowly adding features to it. In first page, you enter data
into a form and click the submit button. This takes you to the second page,
which displays the data from the form; and clicking the submit button on
this page takes you back to the first page--very simple.
My problem is that for the first page (entryPage.jsp), its form bean,
EntryForm.java seems to be executing, but the corresponding action class,
EntryAction.java does not. I have checked two very good books and have
checked my code against sample code, but i can't figure out what's different.
Below, I've listed the struts-config.xml and EntryAction.java files. I know
I must be overlooking something incredibly simple. Thanks for your help.

Re: Struts 1.1 on Tomcat 5.0.18?
Posted by Steve Hill <st...@finelineco.com>.
I had sent a previous message to this list with a complete error listing,
but I'll clarify. I downloaded and installed a new installation of Tomcat
5.0.18. I then downloaded and installed a new installation of struts 1.1,
copying the documentation and example application war files into Tomcat's
Webapps directory, and restarting Tomcat.
Running the http://localhost:808/struts-documentation works fine. Running
http://localhost:808/struts-example gives the following error message. I
followed the other instructions (XML parser, JDBC2, xalan-j) as specified in
v1.16 of the Struts readme file. The exception report I get when running
struts-example is:
description The server encountered an internal error () that prevented it
from fulfilling this request.

Specific suggestions welcome, else I will just start over if Struts 1.1 is
normally known to work successfully on Tomcat 5.0.18. It looks like
something is missing but if the Struts readme docs are correct it should
work. This particular error is a known Sun issue in a previous Tomcat
version. Thanks.

Yes, probably hundreds of people. When do you get that error? Without
more details it's impossible to say what you need to do.

Struts 1.1 on Tomcat 5.0.18?
Posted by Steve Hill <st...@finelineco.com>.
Is anyone here successfully using Struts 1.1 on Tomcat 5.0.18? I am getting
"java.lang.IllegalStateException: zip file closed errors" with any
struts-using code and am wondering if this is a bug and I should go back to
an earlier version of one or the other. Thanks.
