Question

I have an old struts 1 app that has always been built using Ant, which I\'m converting to use Maven instead. The structure of my app is modular, with dependency management i

Answer 1

I also lost a half of day trying to fix this.

It appeared that root was my project pom.xml file with dependency:

    
        javax.servlet.jsp
        jsp-api
        2.1
        provided
    

Other members of the team had no problems. At the end it appeared, that I got newer tomcat which has different version of jsp-api provided (in tomcat 7.0.60 and above it will be jsp-api 2.2).

So in this case, options would be:

a) installing different (older/newer) tomcat like (Exactly what I did, because team is on older version)
b) changing dependency scope to 'compile'
c) update whole project dependencies to the actual version of Tomcat/lib provided APIs
d) put matching version of the jsp-api.jar in {tomcat folder}/lib
