[JBoss AOP] - Re: ATOMIC aspect weaving ?
by flavia.rainone＠jboss.com
JBoss AOP applies the optimal solution according to the specific case. This means that:
- at compile, it checks class by class, verifying all bindings and aspect that apply to that class, and weaving its code. In this case, weaving on a per aspect basis would be costly, because it would force JBoss AOP to weave a single class more than once.
- at load time, it also checks the classes as they become loaded in the jvm. This is also the best solution because, as in the previous case, doing it the other way would force JBoss AOP to process a class more than once. And trying to figure out all classes afected by a specific class would force the load of all classes, which is not what we want
- at runtime (hotswap), JBossAOP weaves at a per dynamic operation basis. This means that, if you add one or more Binding on a single dynamic aop operation, JBoss AOP will first define all join points affected, and, only after this, perform the weaving of the affected classes. Plus, on JBoss AOP there is no flag involved, so, you won't have the unsetting flag cost if you use JBoss AOP in this case.
- at runtime (without hotswap) in this case, the class code has already been weaved, so JBoss AOP just adds the advices to the appropriete advice stacks

[JBoss jBPM] - Signaling Process causes never ending Loop
by Becka
I have currently some Problems with one of my Actionhandlers.
I want to Signal a Process automaticly from within an other.
To now that worked without Problems.
But since i added a Second Transition to the Task, that should be Signaled the Server gets into a never Ending loop due to Leaving and Entering the same Task without any Stop.
This is the Result of a "normal" Signal, just with .signal();
I thought the Name of the Transition in the Signal might help, but the Result is the Same.
The Signaled Task is "waiting for change ...".
It has 2 leaving Transitions "(POSITIVE)" and "(NEGATIVE)"
Here is a Part of the Log:
| 11:56:56,467 INFO [STDOUT] transitionVariableValue = (NEGATIVE)
| 11:56:56,467 INFO [STDOUT] Signaling -> (NEGATIVE)
| 11:56:56,498 DEBUG [GraphElement] event 'before-signal' on 'State(waiting for change ...)' for 'Token(/)'
| 11:56:56,498 DEBUG [GraphElement] event 'node-leave' on 'State(waiting for change ...)' for 'Token(/)'
| 11:56:56,608 DEBUG [GraphElement] executing action 'action[calculate priority]'
| 11:56:56,608 DEBUG [GraphElement] executing action 'action[set status]'
| 11:56:56,608 INFO [STDOUT] Sending signal() in Node State(waiting for change ...)
| 11:56:56,608 DEBUG [GraphElement] event 'before-signal' on 'State(waiting for change ...)' for 'Token(/)'

| 11:56:56,655 DEBUG [GraphElement] executing action 'action[set status]'
| 11:56:56,655 INFO [STDOUT] Sending signal() in Node State(waiting for change ...)
|
And some code:
System.out.println("Signaling -> " + transitionName);
| ciProcessInstance.signal(transitionName);

xmlns:core="http://jboss.com/products/seam/core">
<core:init jndi-name="roc-web-seam/#{reportoperationsSeam}/local"/>
>From the jboss log file I can see that component list is not found.

[Beginners Corner] - NoSuchMethodError when calling from a Schedulable
by realberen
Hello,
I've made a ScheduleService that implements Schedulable and to start with I want it to be my cron-substitute. The function I call is:
public String importCSV(int limit) {
importCSV i = new importCSV();
i.importFromDB(limit);
return "OK";
}
where importCSV is found through
import saers.util.*;
importCSV.importFromDB() is defined as:
public void importFromDB(int limit)
I've set up an mbean for SchedulerService and one based on org.jboss.varia.scheduler.Scheduler. When it is called I get the exception listed under in the logs. The main problem seems to be:
Caused by: java.lang.NoSuchMethodError: saers.util.importCSV.importFromDB(I)V
but as I mentioned, it is already defined:
public void importFromDB(int limit)
so that seems correct, it takes an integer and returns void. Why am I getting a NoSuchMethodError??
Here is the complete log:
