    Migration from Jetty to Tomcat 5.5 issue: precompiled jsp er

    Vladyslav Kosulin Newbie

      We migrate from JBoss 3.2.3/jetty to JBoss 4.0.3SP1/Tomcat 5.5
      Our ear deploys fine, but when i try to open main page in a browser, I am getting an Exception:
      11:37:45,193 ERROR [error_jsp]] Servlet.service() for servlet com.wsc.taxgard.jsp.error_jsp threw exception
      java.lang.NullPointerException
      at org.apache.jasper.runtime.TagHandlerPool.get(TagHandlerPool.java:108)
      at com.wsc.taxgard.jsp.error_jsp._jspx_meth_c_if_0(error_jsp.java:103)
      at com.wsc.taxgard.jsp.error_jsp._jspService(error_jsp.java:73)

      My main page redirects to error.jsp, and this is fine, but it looks like there is an issue with Tomcat loading/handling of JSTL 1.0 in use by our application.

      Any ideas how to fix this?

      Thanks.

          Tomcat 5.5 requires use of it's own Jasper JspC compiler for pre-compilation of JSP.
          The use of default JspC task from ANT 1.6.5 caused the issue.

            Thanks, well said, I have been looking into this issue for a while.
            This is part of my build file and this fixed my problem
