[jBPM Users] - Re: Is there any kind of variable in JBPM4 like 'transient v
by npirard
well, jBPM3 had a nice idea, IMO :-)
especially if the transient data has to be used at several parts of the process, so that it is overall better than mine.
here is what I did, I pass the data when signalling the Custom that uses them with method
ExecutionService.signalExecutionById(String, String, Map<String, ?>)
JPDL :
| <?xml version="1.0" encoding="UTF-8"?>
|
| <process name="CustomParameters" xmlns="http://jbpm.org/4.0/jpdl">
| <start g="161,71,48,48" name="start1">
| <transition g="-30,-37" name="to input_some_info" to="input_some_info"/>
| </start>
| <state g="301,129,209,52" name="input_some_info">
| <transition g="-68,-18" name="to exclusive1" to="exclusive1"/>
| </state>
| <decision g="381,222,48,48" name="exclusive1">
| <handler class="org.jbpm.npi.Exclusive1Handler" />
| <transition g="-58,-18" name="to custom1" to="custom1"/>
| </decision>
| <custom class="org.jbpm.npi.MyCustom" g="361,319,92,52" name="custom1">
| <transition name="to exclusive2" to="exclusive2" g="-68,-18"/>
| </custom>
| <decision g="384,416,48,48" name="exclusive2">
| <handler class="org.jbpm.npi.Exclusive2Handler" />
| <transition name="to wait2" to="wait2" g="-44,-18"/>
| </decision>
| <end g="569,500,48,48" name="end1"/>
| <state name="wait2" g="350,479,92,52">
| <transition name="to end1" to="end1" g="-42,-18"/>
| </state>
| </process>
|
two simple DecisionHandlers :
| package org.jbpm.npi;
|
| import org.jbpm.api.jpdl.DecisionHandler;
| import org.jbpm.api.model.OpenExecution;
|
| public class Exclusive1Handler implements DecisionHandler {
|
| @Override
| public String decide(OpenExecution arg0) {
| return "to custom1";
| }
| }
|
| package org.jbpm.npi;
|
| import org.jbpm.api.jpdl.DecisionHandler;
| import org.jbpm.api.model.OpenExecution;
|
| public class Exclusive2Handler implements DecisionHandler {
|
| @Override
| public String decide(OpenExecution arg0) {
| return "to wait2";
| }
| }
|
|
my Custom :
| package org.jbpm.npi;
|
| import java.util.Map;
|
| import org.jbpm.api.activity.ActivityExecution;
| import org.jbpm.api.activity.ExternalActivityBehaviour;
|
| public class MyCustom implements ExternalActivityBehaviour {
|
| @Override
| public void signal(ActivityExecution activityExecution, String signal, Map<String, ?> parameters) throws Exception {
| System.out.println("signal() - ring the Kremlin !! " + parameters.get("putinPhoneNumber"));
|
| activityExecution.takeDefaultTransition();
| }
|
| @Override
| public void execute(ActivityExecution activityExecution) throws Exception {
| System.out.println("MyCustom.execute()");
| activityExecution.waitForSignal();
| }
|
| }
|
the test class
| package org.jbpm.npi;
|
| import java.util.HashMap;
| import java.util.Map;
|
| import org.jbpm.api.Execution;
| import org.jbpm.api.ProcessInstance;
| import org.jbpm.test.JbpmTestCase;
|
| /**
| * test the possibility to inject parameters at some point of a process without
| * persisting them
| *
| * @author npirard
| */
| public class CustomParametersTest extends JbpmTestCase {
|
| String deploymentId;
|
| @Override
| protected void setUp() throws Exception {
| super.setUp();
|
| deploymentId = repositoryService.createDeployment().addResourceFromClasspath("org/jbpm/npi/CustomParameters.jpdl.xml").deploy();
| }
|
| @Override
| protected void tearDown() throws Exception {
| repositoryService.deleteDeploymentCascade(deploymentId);
|
| super.tearDown();
| }
|
| public void testProcess(){
| Map<String, Object> variables = new HashMap<String, Object>();
|
| //this is a variable that can be persisted without problem
| variables.put("publicInfo", "this is not really secret");
| ProcessInstance processInstance = executionService.startProcessInstanceByKey("CustomParameters", variables);
|
| Execution executionInA = processInstance.findActiveExecutionIn("input_some_info");
| assertNotNull(executionInA);
|
| processInstance = executionService.signalExecutionById(executionInA.getId());
|
| Execution executionInCustom = processInstance.findActiveExecutionIn("custom1");
| Map<String, String> parameters = new HashMap<String, String>();
|
| //this is really secret matter
| parameters.put("putinPhoneNumber", "+7123456789");
| processInstance = executionService.signalExecutionById(executionInCustom.getId(), "mySignal", parameters);
|
| Execution executionInWait2 = processInstance.findActiveExecutionIn("wait2");
|
| assertNotNull(executionInWait2);// breakpoint A
|
| processInstance = executionService.signalExecutionById(executionInWait2.getId());
|
| assertTrue(processInstance.isEnded());// breakpoint B
| }
| }
|
I executed it in debug ; at breakpoint A I found "publicInfo" in table JBPM4_VARIABLE, but not "putinPhoneNumber"
at breakpoint B I do not find anything in JBPM4_VARIABLE. By the way, I would have expected "publicInfo" in JBPM4_HIST_VAR, but it is not. Maybe I have not understood the purpose of this latter table : it is not supposed to record the variables of past executions?

[jBPM Users] - Question about signavio jbpmeditor
by remiel512
Dears, I have a question about deploy signavio jbpmeditor. I follow the userguide to deploy signavio jbpmeditor. When I use [ant start.jboss] command to start up jboss server, signavio worked, BUT start jboss server by using [run.bat] the server shows deploy failed. Check log and I find an error below.
Could anyone tell me what is the problem? Thank you!
