Yes you can. You can use all comparison operators UEL supports (< > <= >= != ==)

You can use the mail-task without any java-code.

Please read the user guide before asking random questions about stuff you encounter. We have done our very best of explaining everything in the user guide. Sending a mail is explained there…

Hi,

this is my process xml file

<process id="provaJavaDelegate" name="delegateJar">
    <startEvent id="startevent1" name="Start"></startEvent>
    <userTask id="usertask1" name="inserimento dati libro1" activiti:candidateGroups="accountancy"></userTask>
    <userTask id="usertask2" name="verifica disponibilita libro1" activiti:candidateGroups="management"></userTask>
    <serviceTask id="servicetask1" name="javaCode" activiti:class="org.activiti.examples.bpmn.servicetask.BackwardsCompatibleExpressionDelegate">
      <extensionElements>
        <activiti:field name="text">
          <activiti:string>Hello World</activiti:string>
        </activiti:field>
      </extensionElements>
    </serviceTask>
    <endEvent id="endevent1" name="End"></endEvent>
    <sequenceFlow id="flow1" name="" sourceRef="startevent1" targetRef="usertask1"></sequenceFlow>
    <sequenceFlow id="flow2" name="" sourceRef="usertask1" targetRef="usertask2"></sequenceFlow>
    <sequenceFlow id="flow3" name="" sourceRef="usertask2" targetRef="servicetask1"></sequenceFlow>
    <sequenceFlow id="flow4" name="" sourceRef="servicetask1" targetRef="endevent1"></sequenceFlow>
</process>

i used this java class

public class BackwardsCompatibleExpressionDelegate implements JavaDelegate {

@Override
public void execute(DelegateExecution execution) throws Exception {

String var = (String) execution.getVariable("text");
      var = var.toUpperCase();
      execution.setVariable("text", var);

System.out
.println(" I am in BackwardsCompatibleExpressionDelegate….");

}
}

its working fine means the process instance is created.
But i have one doubt, from the java class i have set the value for uppercase ,this value where can i get it while executing the process.
Please clear my doubt.

Thanks,
Valarmathi P

Use the RepositoryService to get variables of a running process, so you can verify the values. If it's finished and history is on, use the HistoryService to get historicVariableUpdates (HistoricDetailQuery) for a finished process-instance

I used the RepositoryService class in the below method,i run the jUnit but i can't get the value.

public void startProcess() throws Exception {
RepositoryService repositoryService = activitiRule.getRepositoryService();
repositoryService.createDeployment().addInputStream("provaJavaDelegate.bpmn20.xml",
new FileInputStream(filename)).deploy();
RuntimeService runtimeService = activitiRule.getRuntimeService();
Map<String, Object> variableMap = new HashMap<String, Object>();
variableMap.put("name", "Activiti");
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("provaJavaDelegate", variableMap);
assertNotNull(processInstance.getId());
System.out.println("id " + processInstance.getId() + " "
+ processInstance.getProcessDefinitionId());
}
}

Seriously, I can't do much with that kind of information.

Please post your junit code. What line goes wrong and what you'd expect there …

What do you mean with 'check'? Get the value?

In this case, the sales group will be set as candidateGroup for your user task.
Put the value in a process variable if you want to 'check' its value, and reference the process variable with an expression in your xml.
