#12 How to use Jump in Ant
Hello!
I'm trying to invoke Jump via an Ant call (from Eclipse).
I'm using this call:
<java classname="Jump">
<arg value="Pme4Palm"/>
<classpath>
<fileset dir="${jump-jar-dir}">
<include name="**/*.jar"/>
</fileset>
</classpath>
</java>
I get following exception:
[java] java.lang.IllegalAccessException: Class
org.apache.tools.ant.taskdefs.ExecuteJava can not
access a member of class Jump with modifiers "public

Please tell me how to invoke Jump correctly.

Hello!
I solved the above problem by invoking jump using following
call:
<exec executable="cmd.exe" os="Windows 2000" dir="$\{basedir\}"> <arg line="/c java -cp${jump-jar-dir}/jump.jar;${basedir}/bin Jump -v
com.dapissarenko.pme4palm.Pme4Palm"/>
</exec>
However, now I'm getting this error:
[exec] Exception encountered while operating on
java/io/ObjectStreamField.offset
[exec] java.lang.NullPointerException
[exec] at StackEntry.<init>(StackEntry.java:83)
[exec] at StackEntry.push(StackEntry.java:135)

[exec] --- Info ---

How can I solve this problem?
TIA
