The server does not support version 3.0 of the J2EE web module specification

Question

The server does not support version 3.0 of the J2EE web module specification.

I am getting this error when I execute an application in Eclipse IDE. What is the reason for this?

Answer 1

right click on your project -> Properties --> project Facets then you must change Dynamic Web Module from 3 to 2.5

Answer 2

The error message is quite understandable - you are attempting to execute an application that requires the server to support Servlet Spec 3.0 when it doesn't. You must therefore run the application on a server that complies with that version of the Servlet Specification.

As far as I know you have the following options at your disposal, at the time of writing this:

• Apache Tomcat 7.0
• Glassfish 3.1
• IBM WebSphere 8
• JBoss 6 and 7
• Resin 4
