Set the debug and detail parameters in the web.xml (if you're using 1.0) to
0. If there are none there, add init-param elements with values of 0.

I've seen this solution work very well. When you extend the ActionServlet, you can
override the processPreprocess method to determine if the user has the neccessary
permissions, if the user has a valid session, etc... long before ever getting to the

I'm definitely going to cover some design patterns/strategies related to
Struts and EJB. I've been working on an a Struts/EJB application for over a
year now and have learned a great deal about how to approach this, so this
should be valuable to others. Brian Keeton and I just finished an EJB 2.0
That's sort of what I was saying. In the second action, the one that is called after
the user sees the form data and makes some choices, does the scope equal to request or
session? If you have both of these actions defined as session scope, then I don't
believe a new ActionForm would be
You are absolutely correct. That was my blurry-eyed mistake at 2am. Here's the code
that shows that if nothing is defined, it's session scope:
if (request.equals(mapping.getScope())) {
request.setAttribute(mapping.getAttribute(), instance);
}else{
HttpSession session = request.getSession();
I agree total with you on that. However, I didn't think he was trying to repopulate
from the page. I read it as he wondered why the Vector wasn't still present in the
form on the next go-around. I typically use a Collection for something like the
iterate tag. I don't expect (and wouldn't do it
It seems that maybe you're trying to instantiate a log4j Logger in one of your actions
or ActionServlet like this:
Logger.getInstance( String or class );
and the class (Logger) can't be found by the class loader. Here's a couple of things
to try:
1) Is the log4j.jar in your WEB-INF/lib
Boris is right of course. That's the main reason that I was thinking when I said that.
There's definitely no need for the overhead of synchronization in the case that we
were discussing. Another reason that I was thinking about, but didn't elude to very
well is that you should always try to
Just guessing, but the reason the Vectors are null is probably because the action that
is being called is configured as request scope and not session in the Struts
configuration file. Therefore, after the HTML page is drawn (using the Vectors to
populate the drop-down boxes), the ActionForm is
Not to be a smart aleck about it, but there's a decent set of installation
instructions off the Struts main web site. There might be additional steps that you
need to take based on which version of Tomcat that you're using. Here's the URL:
http://jakarta.apache.org/struts/installation-1.0.html
Here's a code sample that I pulled from one of our actions that does that
very thing. I didn't write, but I know
that it works fine.
