Classpath problems(?)

First some code:

This is my build.xml. Sorry for posting all of it, but I want to make sure that nothing is missing. This build.xml belongs to a project I set up in Eclipse 3.2.1 to learn Hibernate (+ Hibernate tools). Everytime I try to run "codegen" I get:

Buildfile: C:\Java\Eigene Projekte\Hibernate\build.xml
[hibernatetool] Executing Hibernate Tool with a Standard Configuration
[hibernatetool] 1. task: hbm2java (Generates a set of .java files)

java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

Total time: 1 second

This happens when starting from Eclipse and externally with a local Ant install. All external libraries reside in a lib folder next to the build.xml. commons-logging-1.0.4.jar IS in lib, it seems like it is not included in the classpath, but I think <path id="project.class.path"> etc... is correct.

What am I missing here? Is there a way to see the classpath Ant is using?

I think it's <echo message="classpath = ${class.path}"/>. In other words, Ant's a Java program and it passes on the JVM properties from the java.lang.System class.

Customer surveys are for companies who didn't pay proper attention to begin with.

you are just missing some jar files in "toolslib" , look at below, you won't miss it!

<path id="toolslib">
<path location="lib/hibernate-tools.jar"/>
<path location="lib/hibernate3.jar"/>
<path location="lib/freemarker.jar" />
....... add your jar here ............... like commons-logging-xx.jar
I agree. Here's the link:
