I'm trying to run the example application in MyEclipse Reports Tutorial - The Basics. On startup Tomcat gives the following messages:

SEVERE: Error configuring application listener of class org.eclipse.birt.report.listener.ViewerHttpSessionListener
java.lang.ClassNotFoundException: org.eclipse.birt.report.listener.ViewerHttpSessionListener

and

SEVERE: Error configuring application listener of class org.eclipse.birt.report.listener.ViewerServletContextListener
java.lang.ClassNotFoundException: org.eclipse.birt.report.listener.ViewerServletContextListener

So it seems Tomcat can't find the listener classes. Where should these classes be located? How can I correct this problem?

Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Were you able to setup the MyEclipse Reports update successfully after installing MyEclipse ?

There were no problems setting up the MyEclipse Reports.

dipp,
Do you see the MyEclipse Reports libraries in your build path for your project? If so, can you open you project properties, go to the Java Build Path and then the Libraries tab and expand the library group there and make sure none of the JARs are marked with warning or error markers?

You can also click the "Browse" button when you have your deployment selected and drill down to your WEB-INF/lib directory of the deployed app and make sure all the reports libraries are getting there correctly... if they aren't, then we might need to restore the default build path contents... this might just be a config goof.

Thank you for your help.

I did a clean install of MyEclipse but the problem still exists.

The report libraries are on the build path (see screenshot at http://www.saunalahti.fi/tkot/libraries.jpg ) and none of them are marked with a warning or an error. I browsed to WEB-INF\lib and it's empty! How can I restore the default build path contents?

dipp,
Thank you for the screenshot. You need to browse to WEB-INF/lib for your *deployed* app, not for the project iself... the libraries are not copied into the /lib directory until deployment time.

From the deployment manager, you can select the deployment and click "Browse" to jump right to the deployed directory and check it.

I am having this same problem. The WEB-INF/lib folder is either missing or empty in the deployed folders. I have tried following the tutorial, creating my own project, and downloading the Examples On Demand project. Deployments to WLS 9, and ME Tomcat behave the same -- no lib files and listener exceptions.

In the project, the "Report Web Libraries" library in the project all points to jars in MyEclipse 7.5/configuration subfolders. For some reason they are not getting copied to the deployment folders. I tried checking "Report Web Libraries" in the "Order and Export" tab of the build path dialog, but it made no difference.

Just found a solution. In the projects Properties->MyEclipse->Web, Deployment tab. Under Library Deployment Policies, unchecked workbench default and checked JARs from User Libraries. When I redeployed, I got the jars into the lib folder, and the app worked.

cbattis,
Good to know that you are all set and thank you for posting your findings.
