Hi,

Sorry if asking stupid questions, but I am quite new to Hibernate ...
I tried to use Hibernate 2.1 in some PostgreSql and Eclipse 2.1.2 (on XP, SDK 1.4.1_03, J2EE 1.4 ) test project,
but after getting some NullPointer exceptions on connection I startet back with Examples ...

But he only thing that I can make work there is by using following bat fiile:

> set JDBC_DRIVER=lib/pg74jdbc3.jar
> set CP=lib/ant-1.5.3.jar;lib/ant-optional-1.5.3.jar;lib/junit-3.8.1.jar;lib/xerces-2.4.0.jar;%JAVA_HOME%/lib/tools.jar
> java -cp %CP% org.apache.tools.ant.Main -Ddriver.jar=%JDBC_DRIVER% -f run_eg.xml run_eg

where xpl file is:

<!-- Hibernate ANT Run Script. -->
<project name="Hibernate" default="jar" basedir=".">

<!-- set global properties for this build -->
<property name="src.dir" value="src"/>
<property name="lib.dir" value="lib"/>
<property name="jdbc.dir" value="lib"/>
<property name="egsrc.dir" value="eg"/>
<property name="jar.name" value="hibernate2"/>
<property name="javac.debug" value="on"/>
<property name="javac.optimize" value="off"/>
<target name="run_eg" description="Run simple (eg) example">
<echo message="*** Run eg application"/>
<java
classname="org.hibernate.auction.Main"
fork="true"
failonerror="true">
<classpath>
<fileset dir="${lib.dir}">
<include name="**/*.jar"/>
<include name="**/*.zip"/>
</fileset>
<pathelement path="${jar.name}.jar"/>
<pathelement path="${src.dir}"/> <!-- properties files live here -->
<pathelement path="${egsrc.dir}"/>
</classpath>
</java>
<echo message="for more examples, download the hibernate-examples package"/>
</target>

</project>

Here I get:

C:\AppDevelop\hibernate-2.1>java -cp lib/ant-1.5.3.jar;lib/ant-optional-1.5.3.jar;lib/junit-3.8.1.jar;lib/xerces-2.4.0.j

But when I try to use external Ant (in process I upgraded up to 1.6.1):
