Hi Bruno, Two hints: 1. Did you modify file src/config/jbpm.cfg.xml? It should look like this: <jbpm-configuration> | | <jbpm-context> | <service name="persistence" factory="org.jbpm.bpel.persistence.db.DbPersistenceServiceFactory" /> | <service name="message" factory="org.jbpm.msg.db.DbMessageServiceFactory" /> | <service name="scheduler" factory="org.jbpm.scheduler.db.DbSchedulerServiceFactory" /> | <service name="logging" factory="org.jbpm.logging.db.DbLoggingServiceFactory" /> | <service name="authentication" factory="org.jbpm.security.authentication.DefaultAuthenticationServiceFactory" /> | <service name="integration"> | <factory> | <bean class="org.jbpm.bpel.integration.jms.JmsIntegrationServiceFactory"> | <field name="defaultDestinationName"> | <string>queue/testQueue</string> | </field> | <field name="defaultConnectionFactoryName"> | <string>java:ConnectionFactory</string> | </field> | </bean> | </factory> | </service> | </jbpm-context> | | <!-- hibernate configuration resources --> | <string name="resource.hibernate.cfg.xml" value="hibernate.cfg.xml" /> | | <!-- configuration resources in jbpm-{version}.jar --> | <string name="resource.business.calendar" value="org/jbpm/calendar/jbpm.business.calendar.properties" /> | <string name="resource.converter" value="org/jbpm/db/hibernate/jbpm.converter.properties" /> | <string name="resource.action.types" value="org/jbpm/graph/action/action.types.xml" /> | <string name="resource.node.types" value="org/jbpm/graph/node/node.types.xml" /> | | <!-- configuration resources in jbpm-bpel-{version}.jar --> | <string name="resource.default.modules" value="org/jbpm/bpel/def/modules.properties" /> | <string name="resource.parsers" value="org/jbpm/bpel/par/parsers.xml" /> | <string name="resource.varmapping" value="org/jbpm/bpel/variable/exe/varmapping.xml" /> | <string name="resource.activity.readers" value="org/jbpm/bpel/xml/activity.readers.xml"/> | <string name="resource.catalog.readers" value="org/jbpm/bpel/xml/catalog.readers.xml" /> | <string name="resource.endpoint.factories" value="org/jbpm/bpel/integration/exe/endpoint.factories.xml" /> | | </jbpm-configuration> 2. Notice the jbpm-configuration/jbpm-context/service[@name='integration']/factory/bean/field[@name='defaultDestinationName'] element in the configuration above. It specifies the JNDI name of the default JMS queue to use for handling incoming web service requests. Did you delete this queue or otherwise modified your JBoss AS installation? jBPM BPEL 1.1.Beta2 was tested under JBoss AS 4.0.3.SP1 and 4.0.4.GA in the default server configuration.
