illegalargumentexception - Project running on Netbeans but not on Tomcat as War file

Question

I made a project on Netbeans on my local machine with JDK 1.7 (32-bit) On running the application (using tomcat 8.0 server on netbeans), it works perfectly on http://localhost:8080/WebApplication1.

I copied the war file from the dist directly and transferred it to my Windows VM server with tomcat 8.0 and jdk 1.8 installed (64-bit). Then the war file was uploaded through tomcat's manager web app.

Note: 'localhost:8080/' and 'localhost:8080/manager' ran without any issue.

However, when I go and run the application (http://localhost:8080/WebApplication1) - it throws the following errors.

The <%page import %> I have in my JSPs are 'java.util.*' and 2 java classes which are part of my project. Rest my java classes import some 'java.' packages

Additional info:

I have set 'Path' environment variable to 'C:\Program Files\Java\jdk 1.8\bin'
I have tried including 'org.apache.jasper.jar' to my project (& war) too
jdbc4.jar is also imported in library

What seems to be the problem? I am unable to make out the source of the problem. Is it because of 32-bit vs 64-bit? or jdk 1.7 vs 1.8? or missing environment variable? or problem in tomcat configuration? something else?

Could it be an issue with Tomcat's 'compilerSourceVM' setting? By default Tomcat will compile JSPs using Java 1.6. tomcat.apache.org/tomcat-7.0-doc/jasper-howto.html — Dec 2 '14 at 20:35

Problem was in my import statement, which included:

Original code

 <%@page contentType="text/html" pageEncoding="UTF-8" language="java" import="java.util.*,mypackage.one.*,mypackage.two.*;"%>

The issue was the ; at the end of the import statement!

Corrected code:

 <%@page contentType="text/html" pageEncoding="UTF-8" language="java" import="java.util.*,mypackage.one.*,mypackage.two.*"%>
