If you have a workflow process definition and create multiple instances of the
process, is there a way to get a list of all the processes that you have
started?
Let's say we have a method to start processes as follows, with a static
jbpmConfiguration member visible somewhere and using hibernate for persistence:
| public long startProcess(String orgNumber, String suborgNumber) throws
RMSException{
| long processID = -1;
| log.info("Entering startEfileDestructionProcess");
|
| //Check if the jbpmConfiguration has been setup
| if( jbpmConfiguration == null ){
| //retrieve it
| log.info("JBPMConfiguration was null, creating
instance.");
| jbpmConfiguration = JbpmConfiguration.getInstance();
| }
|
| //Doing a try and catch for all so the RMSException can contain
the relevant info
| // Lookup the pojo persistence context-builder that is configured
above
| JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
| log.info("Retrieved jbpmContext.");
| try {
|
|
| //GraphSession graphSession =
jbpmContext.getGraphSession();
|
| //ProcessDefinition processDefinition =
| log.info("Creating process");
|
| // With the processDefinition that we retrieved from
the database, we
| // can create an execution of the process definition
just like in the
| // hello world example (which was without persistence).
| ProcessInstance processInstance =
jbpmContext.newProcessInstance("JBPMEfileProcess");
| log.info("Created process");
| processID = processInstance.getId();
| log.info("ProcessID is ["+processID+"]");
|
| //Set the key variables
|
processInstance.getContextInstance().createVariable("OrgNumber",orgNumber);
|
| log.info("Set Org Number");
|
processInstance.getContextInstance().createVariable("SubOrgNumber",suborgNumber);
| log.info("Set SubOrg Number");
|
| // Now the processInstance is saved in the database.
So the
| // current state of the execution of the process is
stored in the
| // database.
| //Connection myConnect = jbpmContext.getConnection();
| //PreparedStatement myStatement =
myConnect.prepareStatement("SET IDENTITY_INSERT JBPM_PROCESSINSTANCE OFF");
| //myStatement.execute();
| //myStatement.close();
| processInstance.signal();
| jbpmContext.save(processInstance);
| log.info("Saved New Process");
| }catch(Exception e){
| String message = "Error creating new RMS
process["+e.getMessage()+"]";
| e.printStackTrace();
| throw new RMSException(1,message);
| }
| finally {
| // Tear down the pojo persistence context.
| jbpmContext.close();
| }
|
| log.info("Exiting startEfileDestructionProcess, created
processID["+processID+"]");
| return processID;
| }
|
Is there a way to get a list of all the processes, short of saving the process
ids myself somewhere?
