JBoss 4.0.4 appears to re-compile JSPs every time the server starts up
regardless whether the JSPs have changed or not. In 4.0.3SP1 and previous
versions, JSPs would only pre-compile (per our web.xml settings) if they were
changed.
The result is an extra 2 to 3 minutes added to server startup time.
I have searched forums and Wiki for any hint of a possible configuration change
that would cause this but didn't find anything. I just wonder if there is there
something new in 4.0.4...
This behavior hurts most in our development environments where JBoss restarts
can be very frequent.
Here is a snippet of our web.xml showing our pre-compilation settings for a few
JSPs:
<!-- Precompile jsps -->
<!-- root directory -->
<servlet-name>aboutus</servlet-name>
<jsp-file>/aboutus.jsp</jsp-file>
<load-on-startup>20</load-on-startup>
<servlet-name>address</servlet-name>
<jsp-file>/address.jsp</jsp-file>
<load-on-startup>20</load-on-startup>
<servlet-name>addressRefine</servlet-name>
<jsp-file>/addressRefine.jsp</jsp-file>
<load-on-startup>20</load-on-startup>
<servlet-name>allMachineParts</servlet-name>
<jsp-file>/allMachineParts.jsp</jsp-file>
<load-on-startup>20</load-on-startup>
Our web app is fairly straightforward in its use of JavaEE features: stateless
session beans (EJB2.1), JSP/Struts, a couple of MDBs, JNDI (no O/R framework)
to the database. Our development environments work from an exploded ear/war
deployment where we have pointed JBoss to a separate deployment directory, with
deployment directory scanning disabled.
I could certainly have missed something... Any advice would be greatly
appreciated.
Thanks.
