Problem integrating Axis WF-XML Service

Hi!

I am trying to integrate the Shark Wf-XML Service into an own ant-script, 
which basicly starts the same classes as the shark axis server does. 
however I get an exception.

my antscript looks like this:

        <!-- 
================================================================== -->
        <!-- Start Shark Axis Webservice at Port 8081               -->
        <!-- 
================================================================== -->

        <target name="sharkaxis" depends="_prepareConfFile">
               <java classname="org.enhydra.shark.wfxml.SharkServiceImpl"
                        fork="true" 
dir="${basedir}/WebRoot/WEB-INF/classes">
                 <arg value="${basedir}/setup/conf/Shark.conf"/>
                 <arg value="-p"/>
                 <arg value="8081"/>

                 <classpath>
                   <pathelement 
location="${basedir}/WebRoot/WEB-INF/classes"/>
                                <fileset 
dir="${basedir}/WebRoot/WEB-INF/lib">
                                        <include name="*.jar" />
                                </fileset>
 
                                <fileset dir="${shark-lib}">
                                        <include name="*.jar" />
                                </fileset> 
 
                        <fileset dir="${jdbc-lib}">
                                        <include name="*.jar" />
                                </fileset> 
                                <fileset dir="${csh-lib}">
                                        <include name="*.jar" />
                                </fileset>
                 </classpath>
               </java>
        </target>

the exception I get (after shark itself successfully started) is:
