Hi, there

I’m having problems with web application using Weblogic 8.1 and struts 1.1. I’ve configured Weblogic 8.1 from ME 5.1 and I can start Weblogic from ME. I think the configuration is OK. However, after I deploy and start the application (a very simple struts web app), I get errors as follows:

The same application works FINE on both JBoss 4.0 and Tomcat 5.5. Do I need a specific deployment file, such as weblogic.xml for struts web applications? If yes, how to generate it from ME 5.1?

Thanks for any help.

Looks like you are trying to deploy Java 5 code to run inside of a Java 1.4 VM . Go back to your project and make sure you set the compiler settings to 1.4 compliance, and not Java 5 (default).
