Precompiling JSPs fails

2005-04-27 Thread Bud Bach 
Hi, I’m using Tomcat 5.5.9 and JDK 1.5.0_02.  I’m trying to precompile the
Liferay Pro Portal 3.2 JSPs using the ant build script found on the apache
web site:

http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jasper-howto.html#Web%20Appl
ication%20Compilation

modified to add jars placed in common/lib/ext.  JAVA_HOME is set to
/usr/java/jdk1.5.0_02.

When I run the ant script, I get a NullPointerException.  Below is the
script I am using and the output from the ant command.  Any idea what I
might be doing wrong?

Thanks.  -- Bud

JSPs slow to compile?

2005-04-27 Thread Bud Bach 
I am running Liferay Portal Pro 3.3 under tomcat 5.5.9 on fedora fc3 
running on a 1.2ghz p4 w/ 3gb ram.  Initial page loads are taking on the 
order of 30 seconds.  After the initial page load, it takes just a 
second to reload.  30 seconds seems like a long time to initially 
compile the page and load it.  Do I potentially have something 
misconfigured? 

Also, I've tried to precompile the pages with the script in the docs on 
the tomcat website but the script fails with a NullPointerException.  
Has anyone else successfully precompiled JSPs under 5.5 with the script 
on this page:

 http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jasper-howto.html
?  Thanks.  -- Bud

Hummm...  Just changed the jasper init parameter development to false 
in conf/web.xml and now pages load in a couple of seconds or less.  Why 
the huge difference?  Any tips to make it even faster?
