    Jboss jbpm 4.2 integration with spring

    mesa mesa Newbie

      Hi community,

      i have started using jboss jbpm 4.2 and managed to integrate it with spring.

      i am able to deploy the sample process defintion and able to getProcessInstance , but when
      i query for processInstance.getId() it is coming as null.
      i had taken a look at source code and found out that id generation is done within Executionimpl class:
      protected void composeIds() {
      this.id = IdComposer.getIdComposer().createId(processDefinition, parent, this);
      } and id composer is Databaseid composer or memoryIdComposer.

      and default id generator implementation returns null for all process instances.

      i also see <id-generator> in jbpm.cfg.xml and thinks that its value must be overridden somehow.
      database used is mysql.

      thanks
      mayank

          Hi msahai,

          I think you are missing

          <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer" init="eager" />
          


          in your jbpm.cfg.xml

            hi mwohlf,

            i did not get it properly.where i have to add this line.
            do i have to add it within <id-generator> tag.
            can you show me sample cfg , to which you are refering too.

            my sample cfg is:

            <?xml version="1.0" encoding="UTF-8"?>
