Here the process:
| ...
| <fork name="fork1">
| <transition to="ibk-df-classifier" name="1"></transition>
| <transition to="bayes-wf-classfier" name="2"></transition>
| <transition to="svm-df-classifier" name="3"></transition>
| </fork>
|
| <node name="node1" async="true">
| <action class="DoHeavyJob1"/>
| <transition to="join1"></transition>
| </node>
|
| <node name="node2" async="true">
| <action class="DoHeavyJob2"/>
| <transition to="join1"></transition>
| </node>
|
| <node name="node3" async="true">
| <action class="DoHeavyJob3"/>
| <transition to="join1"></transition>
| </node>
|
| <join name="join1">
| <transition to="finish"></transition>
| </join>
|
| <node name="finish">
| <action class="Result"/>
| </node>
| ...
|
In have this scene: Intermediate nodes takes long time executing, so I need the
async="true" for their concurrent execution, and I cannot execute the "finish"
node until ALL intermediate nodes had finished.
In the DoHeavyJob1, DoHeavyJob2 and DoHeavyJob3 ActionHandlers, I have coded
the executionContext.leaveNode(); at the end of the execute method.
| class DoHeavyJob1{
| public void execute( ExecutionContext executionContext ) {
| //Time task Simulation
| Thread.sleep ( 100000 );
|
| executionContext.leaveNode();
| }//execute
| }
|
These actions are executed fine with JobExecutor, and I see that are executed
in a concurrent way.
But, the known org.hibernate.StaleObjectStateException occurs when the last
actionHandler makes the leaveNode.
Please, is there any way to implement this issue?
Thanks
