I have problem to run my apps using Tomcat 7. I got this error:
javax.servlet.error.exception: javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/apache/jasper/runtime/JspSourceImports
But when I run using Tomcat 8, it works fine. I need to use Tomcat 7 because I want to run the Tomcat from Eclipse Helios, and Eclipse Helios does not support Tomcat 8.
I do not know how to fix this. Appreciate your help.
