Some things to check or consider if you want to run from a JAR file:
1) Does your manifest.mf file exist in the /meta-inf directory?
2) Does your manifest.mf file contain the entry "Main-Class:
full.path.and.class.Name" ?
3) Try using <arg line="-jar jarfilename" />
4) To my knowledge, passing in the classname attribute to the Java task
won't help you
if you are using the -jar option.
Good luck,

Subject: launch an application stored in a jar
Hi,
I cannot make Ant launch a class that is stored in a jar file.
I tried many variants, but to no avail.
Thanks in advance

The original version where I lauch the class directly (not from a jar) works
fine :
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
- - - - - - run -->
<property name="entry.point.class"
value="cirb.teletest.project.JJJYNet.Test_project_p_JJJYNetDB" />
<target name="run" depends="compile">
<java classname="${entry.point.class}" fork="yes"
failonerror="true"
dir="data">
<classpath refid="libraries.path" />
<classpath path="${build.dir}" />
<arg value="conf.log4j" />
</java>
</target>
--------------------------------------------------
I use the following manifest file :
MANIFEST.MF file contents (2 lines):
---
Manifest-Version: 1.0
Main-Class: cirb.teletest.project.JJJYNet.Test_project_p_JJJYNetDB
---
The following attempt does not work :
<!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
- - - runFromJar -->
<target name="runFromJar" depends="compile">
<java classname="${entry.point.class}" failonerror="true"
dir="data">
<arg value="-jar ${local.CirbJarfile}" />
<classpath refid="libraries.path" />
<classpath >
<pathelement location="${local.CastorJarfile}" />
<pathelement location="${local.CirbJarfile}" />
</classpath >
<arg value="conf.log4j" />
</java>
</target>

--------------------------------------------------
In the build.xml file, I create the jar
<target name="makeCirbjar" depends="compile">
<delete file="${local.CirbJarfile}" />
<jar jarfile="${local.CirbJarfile}"
manifest="./src/META-INF/MANIFEST.MF"
>
<!-- exclude the Test classes *.class for the jar -->
<fileset dir ="${build.dir}" includes="cirb/"
excludes="**/Test*.class" />
</jar>
</target>
When I check the contents of the jar, I can see the manifest is there.
