Java task - jar woes but classname goes

[Geoff Capper <ge...@ozemail.com.au>]

Hi,

I'm not sure if I'm having a problem with my understanding of java or of 
ant at this stage (or maybe just understanding in general), and I hope 
that someone can point me in the right direction. My problem is as follows:

Background:
Ant: 1.6.1
Java: 1.4.2_04
In my build script I have "compile-app", "run-build" and  "run-app" 
tasks. I am using external jars from Hibernate, so for each of these 
tasks I specify a classpath, for "compile-app" it is simply the main 
Hibernate jar, for the other two it is a fileset of everything within my 
lib/ directory matching *.jar, which includes the main Hibernate jar.

Problem:
If I run "run-build" everything works fine.

If I run "run-app" with a "classname" attribute, having included the 
application jar in the classpath everything works fine.

If I run "run-app" with a "jar" attribute for the application jar 
(jarred using ant with a mainclass manifest element) I get a 
NoClassDefFoundError for one of the Hibernate classes.

I am running with the debug arg, and the output from ant says the jar is 
on the classpath. The classpath isn't changed when I use either 
jar/classname, so to my mind it seems I shouldn't have this problem.

I feel sure I have done something stupid, or misunderstood something 
somewhere, but I cannot figure out what. My apologies if this is the 
same as all the other classpath issues, but I seem to have exhausted all 
of the possibilities presented in other emails on that topic, such as 
duplicate jars etc.

I have included some of the debug stuff below.

Thanks for any help,
Geoff
