This is a JSP issue and there is a forum dedicated for JSP in the Web Development section.

Anyways the problem is quite simple, you are encountering a NullPointerException in your OnWebBeanErrorPage.jsp page.

The line number mentioned in the Exception is the line number from the corresponding servlet generated for your JSP by your web server. In case the point at which is the NullPointerException is thrown is not appared you can locate the "OnWebBeanErrorPage_jsp.java" file inside the "work" folder of your tomcat installation and check what is it that exactly happens at that line and trace that back to your JSP page.
