Try moving from org.jbpm.bpel.ant.ServiceGeneratorTask to org.jbpm.bpel.tools.ant.WsdlServiceTask (in jbpm-bpel-tools.jar). The interface is largely similar, although the tool has been upgraded to generate bpel-deployment.xml along with the WSDL documents. Apart from that, several things had to change between the last beta and the GA version to allow the latter to be stable. It might be best to keep the current versions of your processes on your Beta3 installation and deploy new versions on a GA installation. Also, you should consider migrating to the new deployment procedure as it will put much less burden on what your own module has to do.
