    how to integrate commandservicebean

    Sascha Janz Master

      hi,

      i installed jbpm suite 3.2.3

      i want to use the commandservicebean for my application, but i can't find it.

      what must i do to install the commandservicebean?

          You must use jbpm-enterprise.ear..

            thats what i did.

            i copied the jbpm-enterprise.ear to the deploy directory

            but i got the following error

            10:06:33,316 WARN [ServiceController] Problem starting service jboss.j2ee:service=EjbModule, module=jbpm-enterprise.jar
            org.jboss.deployment.DeploymentException: type-mapping is not initialized: java:
            JbpmDS was not deployed or type-mapping was not configured.
            at org.jboss.ejb.plugins.cmp.jdbc.metadata.JDBCEntityMetaData.getTypeMap
            ping(JDBCEntityMetaData.java:1103)

            but in the logs appears

            10:05:59,410 INFO [ConnectionFactoryBindingService] Bound ConnectionManager 'jboss.jca:service = DataSourceBinding, name=JbpmDS' to JNDI name 'java:JbpmDS'

            where is the error?

              Check your datasource configuration file, it must have a section for the type-mapping:

              <metadata><type-mapping>Hypersonic SQL</type-mapping></metadata>
              

              where the value matches one of the entries in server/jbpm/conf/standardjbosscmp-jdbc.xml.

                ok. added type mapping to the jbpm-ds

                and datasource mapping in the jbosscmp-jdbc.xml

                <jbosscmp-jdbc>
                 <defaults>
                 <datasource>java:JbpmDS</datasource>
                 <datasource-mapping>Oracle9i</datasource-mapping>
                 <create-table>false</create-table>
                 <remove-table>false</remove-table>
                 <pk-constraint>false</pk-constraint>
                 </defaults>
                 <enterprise-beans>
                 <entity>
                 <ejb-name>TimerEntityBean</ejb-name>
                 <table-name>JBPM_JOB</table-name>
                 <cmp-field>
                 <field-name>timerId</field-name>
                 <column-name>ID_</column-name>
                 </cmp-field>
                 <cmp-field>
                 <field-name>name</field-name>
                 <column-name>NAME_</column-name>
                 </cmp-field>
                 <cmp-field>
                 <field-name>tokenId</field-name>
                 <column-name>TOKEN_</column-name>
                 </cmp-field>
                 <cmp-field>
                 <field-name>processInstanceId</field-name>
                 <column-name>PROCESSINSTANCE_</column-name>
                 </cmp-field>
                 </entity>
                 </enterprise-beans>
                 </jbosscmp-jdbc>
                
                


                but now when i execute the following code
                
                
                 Object returnValue;
                 try {
                 GetProcessDefinitionsCommand cmd = new GetProcessDefinitionsCommand();
                 InitialContext initialContext = new InitialContext();
                 LocalCommandServiceHome localCommandServiceHome = (LocalCommandServiceHome) initialContext
                 .lookup("java:ejb/CommandServiceBean");
                 LocalCommandService localCommandService = localCommandServiceHome
                 .create();
                 returnValue = localCommandService.execute(cmd);
                 localCommandService.remove();
                 } catch (Exception e) {
                 e.printStackTrace();
                 throw new RuntimeException("couldn't execute command", e);
                 }
                



                i got

                13:53:20,598 ERROR [LogInterceptor] RuntimeException in method: public abstract java.lang.Object org.jbpm.command.CommandService.execute(org.jbpm.command.Command):
                org.jbpm.JbpmException: couldn't start JTA transaction

                what is now missing?

                it's now nearly two days trying to get it work.......

                  ok finally made it

                  in the jbpm.cfg.xml was jta defined...dont know why or from where i got this file

                  changing it to

                  <jbpm-configuration>
                  
                   <jbpm-context>
                   <factory>
                   <service name="persistence">
                   <factory>
                  
                   <bean class="org.jbpm.persistence.db.DbPersistenceServiceFactory">
                   <field name="isCurrentSessionEnabled"><true /></field>
                   <field name="isTransactionEnabled"><false /></field>
                   </bean>
                   </factory>
                   </service>
                  


                  solved the problem...


                  really a lot things to configure....
