[JBoss jBPM] - Help with concurrent subprocess instances!
by kosulin
I am pretty new to jBPM, and tried to find solution in forums and wike without much success.
Here is what I need:
I have a single (reusable) process which processes a single file with a given name.
To be able to run this process I define a superprocess with task node for user to provide the file name and this process as subprocess. This causes no problems.
I also need to create another process which would take all file names from, say, a specified directory, create sub-process instances for every file, wait for all subprocess instances to finish, and report results from every subprocess to a user for further decision. I do not know how many files there are. This sounds like fork and join with variable number of tokens. How can I implement it? And how to pass parameters in this case?
Also, because all these forked instances have the same process definition, I could try to run concurrent instances of a single transition (I found a reference that this is possible), but how to do this?
And is there way to reflect this concurrency in GPD diagram?
Thanks,
Vlad

[JBoss AOP] - AS 4.0.5 Deployment exceptions in 'all' config
by system.out
I followed the instruction in reference manual to install aop in AS 4.0.5. Here is the exception I get upon starting the server:

Here is what I have done:
1. replace jboss-aop.deployer with jboss-aop-jdk50.deployer in /deploy directory.
2. enable Weaving to true
3. copy pluggable-instrument.jar in /bin
4. modify run.bat to add set JAVA_OPTS=%JAVA_OPTS% -Dprogram.name=%PROGNAME% -javaagent:pluggable-instrumentor.jar
