I have a same problem as posted by you. My JSP with Tomcat are giving me tough time.
I would request if you have a solution for:
"javax.servlet.ServletException: Cannot find ActionMappings or ActionFormBeans collection"
Would appriciate your reply.
Regards.

Well, the google search found a thread with the exact problem i am having... but unfortunately there is no answer.
I have tried to run struts on tomcat 4.1.12 and get the same exception listed above.
Has anyone had this problem and then solved it?
Thanks.

Hi,
I am facing the same problem.Any help would be appreciated.
Thanks,

This problem happens when the server is not able to find mapping for the parameter you are passing as action.
for ex. if your JSP has

your struts-config.xml should have mapping for action parameter i.e. "/login"
something like

and you should have Action (LoginAction) and ActionForm (LoginFormBean) inside WEB-INF/classes folder.
Even after doing this if you are not getting the page try to
give a mapping for login page in struts-config.xml like this

and forward the request to login page from LoginAction.

in the browser call login.do instead of login.jsp
( i.e. here you are calling the Action class which forwards the request to JSP )

I had similar problem when I used Tomcat 4.1.12, Apache Struts 1.1 w/ JDK 1.4.1 -- It has been very frustrating to figure out the root cause of this error -- my problem was fixed when I changed JRE that runs Tomcat back to 1.3.1_06.

Add the following tab in web.xml for action servlet, I had the sdame problem, now it works fine.
<load-on-startup>0</load-on-startup>

Ok, I spent 2 days, 2days!!! searching for this problem. The thing is that this error can be caused, from what I understand by a lot of things. Anything from mistyped closing tag in .xml file, to simply screweing up on a "/" in the root. However, after 2 days all this was fixed and I was still getting this error. And finally FINALLY, not gonna go into how(long trial and error process), I found whats wrong, so for examples sake lets say your webapplication under Tomcat is called Engine and it resides in Engine directory, I added this to Tomcats main server.xml that is in /conf directory:
<Context path="/Engine" docBase="Engine" debug="0" privileged="true"/>
And than it worked, and I rested

of course I tried taking it out and it stopped working so that was it. I have no idea why, any light that you guys can shine on this issue, would be greatly appreciated.

Hi,
Thanks Anand Shivdas. Your nugget worked!. Could you please elaborate a little if possible as to why is it necessary to add the like in the Action Servlet.
Many Thanks

The main problem lies somewhere else. Please check that you have all the jar files required for struts in your web-inf/lib folder. I got this error solved when I copied the files there. In my VSS we had only those files which we were using and we were getting this error. But it seems that struts internally uses some of its own files. So its better to have ALL files in lib instead of having only the ones you are using.
For version 1.1 there are 6 files in total.

Long due for moving to the Struts forum.

I have this problem also.
I use: JBoss 3.2.2, Struts 1.1
I have no problem for a number of trials, it gets fail after several times.
I have tried all solutions above but useless. The solution is just restart JBoss.
However, I am sorry that I don't know the reason at all.

Always remember the rule of thumb that whenever you make modifications to the .xml file, check to see if everything is o.k by opening it in the browser because you might have forgot to close the tags or complete the quotes and so on. Once you are sure this is o.k and still does not work then try suggestions that other people have recommended in this thread because there is no one definite answer for this and it is getting difficult to nail this sucker down.

Hi Friends,

And one thing more I am using my action class as "DisptachAction"...

please help me , by then I can step a head...

Bye...waiting for ur replies

From the stack trace you've shown us, the problem is clearly the fact that the Struts ActionServlet is unable to parse your struts-config.xml file. I don't see the problem from what you've posted, but here's what I'd recommend:

1-Make a copy of your struts-config.xml file
2-Since it's the <action> tag that the message refers to, remove everything between the <action> and </action> tags.
3-Restart your Application and see if you still get the error message.
4-If you don't get the error message, re-type the <action> tag and try restarting again.
5-If you do get an error message, keep removing items until you no longer get an error message. The last thing you removed is what's causing the problem.
6-Once you've identified the portion of the xml that has the problem, fix it.

Hi,

I am very much Thankful to you for your response.

I have only one "action" tag in <action-mappings> and i placed like this after ur suggestion.

<action-mappings>
<action>
</action>
</action-mappings>

But still the same error in the Stack is occuring...

and also this...

javax.servlet.ServletException: Cannot find ActionMappings or ActionFormBeans collection

What can I do my dear friend...

Bye..

If you'll click on the email icon at the top of this post (the second from the left) you can email me directly. If you'll send your struts-config.xml file as an attachment, I'll see if I can help you find the problem.
