I have an application that works perfectly fine on Tomcat 6. I have now moved this application to Tomcat 7 and the JSPs are throwing below compilation exception
Mar 21, 2014 12:05:56 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [jsp] in context with path [/core-tool-5.0] threw exception [Unable to compile class for JSP:

I have taken a look at the java files created by jasper for both tomcat versions and there is one major change that I found. For example, Corresponding to error in line no. 22, the getDependants() method in the java file for tomcat 6 has the following signature:
public Object getDependants() {
return _jspx_dependants;
}
Whereas in case of Tomcat 7, this is
public java.util.Map<java.lang.String,java.lang.Long> getDependants() {
return _jspx_dependants;
}
I had raised this issue couple of months ago too. Did not find a resolution so i switched to tomcat but now we need to do a production release for this code on tomcat 7 hence need a concrete solution to this.
It would be great if some one could please help me identify what do i need to correct to have this issue resolved

回答1:
Finally found the conflicting jar. It is org.osgi.foundation-1.2.0.jar. However this jar is required by another dependency that I am using so need to find a way to resolve this issue.
回答2:
This error is typically caused by compiling JSPs on Tomcat 6 and then trying to run them on Tomcat 7.
If you are pre-compiling your JSPs, make sure that all the Tomcat libraries you are using for pre-compilation are from exactly the same version of Tomcat as the JSPs will be running on.
If you are compiling JSPs on the fly, make sure you empty the work directory when switching from Tomcat 6 to Tomcat 7.
Also make sure that your Tomact 7 installation does not contain any stray libraries from a Tomcat 6 installation and that you don't include any Tomcat JARs with your web application.
回答3:
Adding this line to context.xml should resolve this issue.
