Using precompiled JSPs
Hi
I am using tomcat 6.
I compiled my JSPs (using tomcat’s org.apache.jasper.JspC) and located them
at the same place as all my classes in the WAR (WEB-INF/classes).
When running tomcat and browsing to some JSP files, I found out the tomcat
translate the JSPs to servlets and compile them again under the “work”
directory.
What is the reason it doesn’t use the compiled JSP and recompile the JSP
from scratch?
What should be done to use precompiled JSP in tomcat? (I followed the tomcat
instructions)
Thanks in Advance,
Moti
My JSP seetings in the web.xml looks like that:
<servlet-name>JspServlet</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>development</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>reloading</param-name>s
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>classpath</param-name>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>checkInterval</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>classdebuginfo</param-name>
<param-value>true</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>

Thanks, its work.
The jsp mapping wasn't set correctly.

You should be using the one from the Tomcat doc; yours fails to perform a couple of critical steps.

But did you use it when putting your class files under WEB-INF/classes?

Unnecessary and a complete waste of time. It's inclusion of the mappings for the generated servlets that's critical.

That's the correct doc, but since you didn't use the published script, you didn't generate the necessary servlet mappings. Use the correct script, and make sure you perform this part:
"Then, the declarations and mappings for the servlets which were generated during the precompilation must be added to the web application deployment descriptor. Insert the ${webapp.path}/WEB-INF/generated_web.xml at the right place inside the ${webapp.path}/WEB-INF/web.xml file."

1. see my ant script below
2. I didn’t change the jasper’s package name hierarchy (e.g org.apache.jsp)
3. I did update my war’s web.xml with the jspservet mapping with *.jsp
4. I have assisted by

<target name="compile.jsp">

Did you use the suggested ant script, or did you roll your own mechanism?

Under the proper package name hierarchy?

You likely did not update your WEB-INF/web.xml with the servlet mappings.

Exactly which instructions did you follow?
