One integration point for our system is that we have an event bus from which state change and other interesting events about system activities can be received. One of these events is called a "Discharge" and contains some info about a person and an event that happened at a point it time.
We need to launch a workflow instance on reception of this event. In the future we may need to launch two or more different workflows from this same event or other events available in the system.
So when I introduce a new workflow (via guvnor I suppose) the workflow needs to register itself somehow so that new instances are created when events matching specified criteria are received.
* Is there a mechanism for doing something like this or is it up to me to implement it.
* Where would this "workflow launch" metadata live, it should be packaged with the workflow.
* Can I query guvnor for which workflows are available and get metadata from them so i can setup the JMS filter
ok, I'm out of my depth now. Not sure of the correct approach.

[jBPM] - jBPM5 snapshot

Hi all, Kris,
First of all - I want to say, that I really like the design and appreciate your work! The application is amazing!
Now to my question - I'm testing the latest snapshot of jBPM5 with guvnor integration. My usecase is as follows:
- create simple process (start - user task - end)
- deploy it using eclipse guvnor plugin along with forms and image (similar to screencast by Kris)
- start the new process using jBPM console
It sort of works, but I have several issues I'm unable to sort out by myself.
- when I delete entry from KB (using eclipse), it disapears from the web interface (Guvnor repository), but I'm unable to put it back - eclipse says it already exists in the defaultPackage,
- when I update process and rebuild the package, the changes in the process doesn't seem to go thru to the console, the console shows version 0 next to the process and the process seems to be unchanged,
I'm not sure if I'm using it correctly, if I should fill bugreport or if it has been simply still working on...
Any feedback is welcome, Thank you!

We are experiencing the same issue with before/after lightweight advices inside container, JBoss AS 5.1.0, with both xml and annotation configuration
AOP version 2.1.6.GA_CP01
Xml Configuration
<?xml version="1.0" encoding="UTF-8"?>
<aop xmlns="urn:jboss:aop-beans:1.0">
<aspect class="com.intuit.cg.services.ds.aop.DocTypeResourceAspect"
scope="PER_VM" />
<bind
pointcut="execution(* com.intuit.cg.services.ds.docstore.service.resource.DocTypeResourceImpl->*(..))">
<before name="beforeAdvice" aspect="com.intuit.cg.services.ds.aop.DocTypeResourceAspect" />
</bind>
</aop>
Aspect class
public class DocTypeResourceAspect {
@Override
public void beforeAdvice(@JoinPoint JoinPointBean joinPointBean)
{
super.beforeAdvice(joinPointBean);
getLogger().info("beforeInvoke:" + joinPointBean);
}
}
Exception we are getting:
org.jboss.aop.advice.NoMatchingAdviceException: No matching around advice called 'beforeAdvice' could be found in com.intuit.cg.services.ds.aop.DocTypeResourceAspect for joinpoint Method[method=public javax.ws.rs.core.Response com.intuit.cg.services.ds.docstore.service.resource.DocTypeResourceImpl.getDocTypes()]

Classical around advices and interceptor work just fine, we even tried to modify aop.xml to explicitly use
<property name="instrumentor">org.jboss.aop.instrument.GeneratedAdvisorInstrumentor</property>
even that it's supposed to be default instrumentor, but it didn't help.
What version of container supports lightweight advices?

[JBoss Web Services] - Webservice deployment and namespace containing # character

Hello,
While developping a webservise with JBossWS, I've encountered the following problem. One of the namespace in the WSDL contains a '#'. Let's call it http://mynamespace.com/# http://mynamespace.com/# . As I'm not the author of the WSDL, I can't really change these namespaces.
When JBoss try to deploy my Webservice, an error occurs because Jboss is looking for a file called .../server/default/tmp/jbossws/mynamespace.com#.xsd ... but this is not even a valid file system name (even if the file exists).
I think this is related to http://lists.jboss.org/pipermail/jbossws-users/2008-April/005280.html http://lists.jboss.org/pipermail/jbossws-users/2008-April/005280.html
If i look inside org/jboss/ws/metadata/wsdl/xsd/SchemaUtils.java/ on http://grepcode.com/file/repository.jboss.com/maven2/org.jboss.ws.native/... http://grepcode.com/file/repository.jboss.com/maven2/org.jboss.ws.native/..., there is actually a fix that replace all '?', ':' and '/', but nothing about '#'.
I'm using JBoss 4.2.2 and this is quite annoying. Is there any fix or workaround (I just can't modify the wsdl, so at the end, these elements should be belonging to the http://mynamespace.com/# http://mynamespace.com/# namespave, and not http://mynamespace.com/ http://mynamespace.com/
Thank you,
Aurélien Lansmanne.

Hi,
After some digging around the information spread over the web, I have found the solution:
* Enable load time weaving in the file JBOSS_HOME\server\production\deploy\*jboss-aop-jdk50.deployer\META-INF\jboss-service.xml*
* Copy JBOSS_HOME\server\production\deploy\jboss-aop-jdk50.deployer\pluggable-instrumentor.jar to JBOSS_HOME\lib\endorsed folder
* Enable the agent in run.bat adding the following line:
set JAVA_OPTS=%JAVA_OPTS% -javaagent:%JBOSS_ENDORSED_DIRS%\pluggable-instrumentor.jar
*Be sure you have:*
- Your aspects deployed in the "*deploy*" folder either a .jar or .aop file
- In case of .jar: You must have a <filename>*-aop*.xml in the "*deploy*" folder (preferred, more flexible)
- In case of .aop: Only be sure there is *META-INF/jboss-aop.xml* containing the aspect definition in your package
Cheers,
Bruno
