Subject java.lang.NoClassDefFoundError after adding <permissions> element to a java task
Date Tue, 08 Jan 2008 19:11:38 GMT
I have the following ant task :

    <target name="run">
        <java classname="helloworld.BPELClient">
            <classpath>
                <pathelement location="target/classes"/>
                <pathelement location="target/database"/>
                <fileset refid="tuscany.jars"/>
                <fileset refid="3rdparty.jars"/>
            </classpath>
        </java>
    </target>


When I run this, everything goes ok, but when trying to exit I get the
following exception :

   [java] java.security.AccessControlException: access denied

   [java]     at

After I fix the security problem by adding the permissions element to
the java task

            <permissions>
	        <grant class="java.security.AllPermission"/>
	    </permissions>


I start getting NoClassDefFoundError exceptions and the application
does not even get started ...
