changes to run activiti 5.9 flows in java over 5.8 seeked

[aparneshgaurav]

Using the following code , i was able to run my activiti 5.8 version flows , now the process id and name of the flows are changed,
Now the error is shown the process with the given process id has not been deployed.Moreover , .bpmn files are generated for flows
instead of .activiti files. Please susggest changes to run activiti 5.9 over running flows in 5.8 .




// ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneInMemProcessEngineConfiguration().buildProcessEngine();
      ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration().setJdbcUrl("jdbcostgresql://localhost:5432/postgres").setJdbcDriver("org.postgresql.Driver").setJdbcUsername("postgres").setJdbcPassword("postgres").setJobExecutorActivate(true).setDatabaseSchemaUpdate("true").buildProcessEngine();
      RepositoryService repositoryService = processEngine.getRepositoryService();
      // code to deploy the process
      repositoryService.createDeployment().addClasspathResource("diagrams/MyProcess.bpmn20.xml").deploy(); //DataBaseNodeTest , DataBaseQueryFetchAndForward , SchedulerNodeTest , FtpNodeTest ,
      RuntimeService   runtimeService = processEngine.getRuntimeService();
      // code to run the process instance
      ProcessInstance processInstance = runtimeService.startProcessInstanceById("MyProcess");



Thanks,

runtimeService.startProcessInstanceById("MyProcess");

-> this is wrong. You should use startProcessInstanceByKey("MyProcess"). The ID of the processDefinition is auto-generated. When using the byKey method, you always start the latest version of your process…

Even after i used startProcessInstanceByKey , this is what i got , i have checked by deployment id that my processes are getting deployed correctly. And thanks a lot for replying . If you could suggest anything more.

Also as you can see the xml generated for the flow has process id as "process1" , so i used startProcessByKey or Id using "process1" , this also could not help . Also if you could tell me a guide which shows to execute activiti 5.9 flows.

Thanks.

You shouldn't "generate" or convert the activiti files. You should right-click on your activiti-project in eclipse (with designer plugin) and say "generate deployment resources". Unpack the zip/bar in the deployment-folder and extract the bpmn-file you need.

If the properties-pane in Activiti Designer for the process you designed says "process1", this is the key you should use when starting a process (using startProcessByKey)

[aparneshgaurav]

Thanks , checking that out.

How to extract form .bpmn file from the .bar file in windows , which software to use ?

It would really help if you read the manual BEFORE asking questions on the forum:

http://activiti.org/userguide/index.html#N106B5

To deploy processes, they have to be wrapped in a business archive. A business archive is the unit of deployment to an Activiti Engine. Basically a business archive is equivalent to a zip file. It can contain BPMN 2.0 processes, task forms, rules and any other type of file. In general, a business archive contains a collection of named resources.

It's a zip-file… rename to zip or open with favorite archiving software

Thanks loads , ***************relief********************* , after creating multiple technology nodes , was little nervous why not able to migrate to 5.9 , thanks a lot dude specially for your quick responses.
