static variable in actionhandler

[ajanz]

i got a simple actionhandler with a static int var. this should be a counter, so every time the actionhandler is called the counter should be incremented.

but it remains zero. is the class completely unloaded after calling?

code is

public class MyHandler implements ActionHandler {

 static int counter=0;

 public void execute(ExecutionContext arg0) throws Exception {
 counter++;
 System.out.println("Counter:" + counter);
 }
}

Hmm... I would expect so, since they are related to processinstances (versioning is related to them). Not that it could be changed I guess, but the behaviour you see is not weird to me

ah ok. i understand.

i also got an rulesactionhandler and i want the rules to be loaded only once...

do you have an idea how to do this?

Well,

I use the spring jbpm integration stuff and configur a handler in spring for
this purpose.

Perhaps the Singleton design pattern would do the trick. See any design patterns book for how to implement and use.

thats what i already did

i use

public class MySingleton{

 static MySingletoninstance = new MySingleton();

 static long count =0;

 public static MySingletongetInstance(){
 return instance;
 }
