Hi,
We are in a web based development effort where we are using J2EE,JSP, EJBs and Weblogic.
We observe that the initial invoke of a JSP takes some considerable time to process. (to convert from JSP to Servlet). From the next invocation it is reasonably faster.
We are using JDK1.2.2.
Is there a way we can fast up the inital JSP processing. I am wondering if moving to a later JDK will help it etc.
KIshore.

You can precompile the JSPs as they are deployed into weblogic. You need to add the following to your weblogic.xml file within you web application:
<jsp-descriptor>
<jsp-param>
<param-name>precompile</param-name>
<param-value>true</param-value>
</jsp-param>
</jsp-descriptor>
That will precompile them on deployment, obviously with an extra time hit at deployment time.
