Subject RE: Tomcat 5.5.7 deployer ExceptionInInitializer error in Struts getMessageResources
Date Tue, 15 Feb 2005 22:37:56 GMT
Oops, great apologies. I just checked my XP configuration. As that is a
development machine, we had the "<jasper2" task commented out. When
running jasper we also get an exception, albeit it a slightly different
one.

"ant compile" works great on jakarta-tomcat-5.0.28, but will not compile
on jakarta-tomcat-5.5.7. This is for both XP and Linux (SuSE Linux
Enterprise Server 9), though the jasper errors are slightly different.

Any suggestions at all on how to better diagnose this?

Thank you - Richard

Here's the XP error:

Subject: RE: Tomcat 5.5.7 deployer ExceptionInInitializer error in
Struts getMessageResources


Sven,

Sorry I was unclear. I should have said that under Windows XP it
"compiles" fine. Same version of Tomcat (5.5.7), Ant (1.6.2) and similar
versions of Java:
XP:
 c:\EclipseProjects\workspace\stars>java -version
 java version "1.5.0_01"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)
  Java HotSpot(TM) Client VM (build 1.5.0_01-b08, mixed mode, sharing)
SuSE Linux
  user1:~/tc55-deployer> java -version
  java version "1.5.0_01"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_01-b08)
  Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_01-b08, mixed mode)
  user1:~/tc55-deployer>

What is even weirder (which probably means it is just a config issue
somewhere) is that when I set up a log4j.properties file to see if that
will illuminate the problem in jasper, I get a different exception
(NPE).

I've attached two runs below that show where this happens.

Thank you - Richard

Hi,
   What do you mean by "Under Windows XP it deploys
fine." ?  I thought your problem is compiling?  This
deployer (manager webapps) compiles okay in XP and not
in SuSE?
