      Someone see anything that could be wrong?

      Instanciation code:

       JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
       try {

       processInstance.signal();
      
       jbpmContext.save(processInstance);
      
       }
       catch (Exception e) {
       e.printStackTrace();
       }
       finally {
       jbpmContext.close();

      Help!

        • 1. Re: new instance
          Ronald van Kuijk Master

          I normally do

           ProcessInstance pi = new ProcessInstance( pd );
           pi.signal();
          


          to start a process, but that should not make a difference...

          Turn on debug logging and see what happens

            Thanks for the quick reply kukeltje. I'm really getting nuts with this. Here's the log, please let me know if is enough for you.

            By the way, i've tried the code the same way than I, and the result was the same.

              I just tried your code and it worked for me.

              What is strange is in your logs there is no NODE_ assigned in the insert statement for JBPM_TOKEN:

              13:37:06,750 DEBUG [LongType] binding null to parameter: 11


              I wonder if your process deployed properly? Can you check in your db if you have the nodes for this processdefinition (id=15 according to the logs):

              SELECT * FROM jbpm_node j where PROCESSDEFINITION_ = 15


              This should return three rows for the nodes 'start', 'first', 'end'.

                Hello Martin, thanks for your feedback.

                Regarding your post, you got the rabbit! I get no rows for that query. In fact I only get rows for the first two process that I deployed, and I going on 15th.

                The code i'm using to deploy is this:

                JbpmConfiguration jbpmConfiguration = JbpmConfiguration.getInstance();
                 JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
                 try {
                 ProcessDefinition p = new ProcessDefinition("myprocess");
                
                 p.parseParZipInputStream(new ZipInputStream(new FileInputStream("c:\\myprocess.par")));
                
                 jbpmContext.deployProcessDefinition(p);
                
                
                 }
                 catch (Exception e) {
                 e.printStackTrace();
                 }
                 finally {
                 jbpmContext.close();
                 }

                  You shouldn't create a new ProcessDefinition object by calling

                  ProcessDefinition p = new ProcessDefinition("myprocess");

                  first.

                  Instead, create it like this:
                  ZipInputStream zipInputStream = new ZipInputStream(new FileInputStream("c:\\myprocess.par"));
                  ProcessDefinition processDefinition = ProcessDefinition.parseParZipInputStream(zipInputStream);
                  jbpmContext.deployProcessDefinition(processDefinition);
                  zipInputStream.close();
