I'm currently working on a xCP 2.0 project with Documentum 7.0 and I'm trying to run a Java Service inside a workflow. The Java Service works alright when the function I use does no more than return a "some_string" String. But as soon as I try the actual thing and use documentum specific Objects like:
IDfSession mySession = getSession();
I get these exceptions right here:
java.lang.RuntimeException: Could not invoke the method 'test' from interface 'class com.gemp1.Test' from BOF module 'gemp1_xCPJava' in Process Template: 'Peticion de Nuevo Producto v2' - Activity: 'Execute Java Service'.

My Java class:
package com.gemp1;
import com.documentum.fc.client.*;
import com.documentum.fc.common.DfException;
public class Test extends DfSingleDocbaseModule {
public String test() {
String result = "Hello12345";
return result;
}
public String[] getUsers() throws DfException {
String docbaseUsers[] = new String[200];
IDfCollection coll = null;
IDfSession mySession = getSession();
String myQuery = "select user_name from dm_user";
IDfQuery myDFQuery = new DfQuery(myQuery);
coll = myDFQuery.execute(mySession, IDfQuery.DF_QUERY);
int i=0;
while (coll.next()) {
docbaseUsers[i] = coll.getString("user_name");
i++;
}
return docbaseUsers;
}
}
And finally my javamodule file:
<?xml version="1.0" encoding="UTF-8"?>
<nsJavaModule:JavaModule xmlns:nsJavaModule="http://xcp.emc.com/javamodule" urn="urn:gemp1:com.emc.xcp.artifact.javamodule.category:Artifacts/Java Modules/xCPJava.javamodule" categoryId="com.emc.xcp.artifact.javamodule.category" name="xCPJava" label="xCPJava" implementationClass="com.gemp1.Test">
<implementationJars contentPath="content/modules/xCPJava.jar"/>
<implementationJars contentPath="content/modules/dfc.jar"/>
</nsJavaModule:JavaModule>
Am I missing something?
