Removed line 22
<property name="s" value="${path.separator}" />
Changed line 23
<property name="ozone.dir" value="../.."/>
to
<property name="ozone.dir" value="../../build"/>
And line 26
<property name="jar.dir" value="${ozone.dir}/bin"/>
to the lib directory
<property name="jar.dir" value="${ozone.dir}/lib"/>
And line 30-32
- <property name="cp"
value="${build.dir}${s}${ozone.dir}${s}${jar.dir}/ozone.jar"/>
- <property name="cp"
value="${cp}${s}${jar.dir}/jndi.jar${s}${jar.dir}/castor.jar${s}${jar.dir}/j
avaclass.jar${s}${jar.dir}/w3c-dom.jar${s}${jar.dir}/xalan.jar${s}${jar.dir}
/xerces.jar"/>
- <property name="classpath"
value="${cp}${s}${jar.dir}/jakarta-regexp.jar${s}${jar.dir}/jsdk.jar${s}${ja
r.dir}/junit.jar${s}${jar.dir}/omquery.jar${s}${jar.dir}/xtdash.jar${s}${jar
.dir}/jta-spec1_0_1.jar"/>
To the cleaner
+ <!--Classpath-->
+ <path id="classpath">
+ <pathelement path="${build.dir}"/>
+ <fileset dir="${jar.dir}">
+ <include name="**/*.jar"/>
+ </fileset>
+ </path>
And line 63
- <target name="classes" depends="prepare">
- <javac srcdir="${src.dir}"
- destdir="${build.dir}"
- classpath="${classpath}"
- includes="*.java"
- />
- </target>
To use the new classpath reference
+ <target name="classes" depends="prepare">
+ <javac srcdir="${src.dir}"
+ destdir="${build.dir}"
+ classpathref="/ozone-dev/08-2001/classpath"
+ includes="*.java"
+ />

Yes it helps a lot. I'll take a look at it tonight and see if I can figure
