configuring jikes for jsp compilation

[adam kramer <ad...@monkey.org>]

I'm trying to get ibm's jikes working for jsp compilation instead of javac
to avoid the memory leak and improve initial compilation performance.
I'm using tomcat 4.0.4 with j2sdk1.4.

I have downloaded and compiled jikes from source and placed the jikes
exectutable in /usr/bin

I have changed the $CATALINA_HOME/conf/web.xml jsp servlet config to:
  <servlet>
    <servlet-name>jsp</servlet-name>
    <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
    <init-param>
      <param-name>logVerbosityLevel</param-name>
      <param-value>WARNING</param-value>
    </init-param>
    <init-param>
      <param-name>jspCompilerPlugin</param-name>
      <param-value>org.apache.jasper.compiler.JikesJavaCompiler</param-value>
    </init-param>
    <load-on-startup>3</load-on-startup>
  </servlet>

and I get this error when trying to run example/ jsp pages:

org.apache.jasper.JasperException: Unable to compile class for JSP
/usr/local/jakarta-tomcat-4.0.4-LE-jdk14/work/Standalone/blah.blah.edu/examples/jsp/include/include$jsp.java:0:0:0:0:

/usr/local/jakarta-tomcat-4.0.4-LE-jdk14/common/lib/naming-resources.jar
                .


Should I be setting a classpath in the web.xml file? There is no example
of how to do this so I wasn't sure of syntax. examples = good.

Thanks,
Adam Kramer
