[jboss-user] [MQ] - Is there a max. Message Queue size?
Hello, I hope I have chosen the right forum ... I have a MDB that receives data to process from an external application. Currently this works very well. In rare conditions there can be really a flood of messages, so there may be thousands of messages, waiting to be processed by the MDB. My question now is: Is there a max size of the message queue? Is there a risk that messages might get lost, if there are much more messages than can be processed at the moment? By the way: I am using JBoss 4.2 Thanks in advance for every answer Andreas View the original post : http://www.jboss.org/index.html?module=bbop=viewtopicp=4264273#4264273 Reply to the post : http://www.jboss.org/index.html?module=bbop=postingmode=replyp=4264273 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [jBPM Users] - Re: EventListener questions
I just tried it. I put a breakpoint and used the HSQL's DatabaseManager to have a look at the database. There is no task persisted yet. However I could not find a statement INSERT INTO .. for the task table in the Hibernate debug output before my query for the task. I put an additional breakpoint after the EventListener's notify()-method is completed and then the task is found in the database. So it seems that when the EventListener is notified of the activity's start the task has not been created yet although the activity is already the active one in the execution. Hibernate queries are hard to log in a readable way. I can still post them but if you need them you could easily reproduce them with the supplied unit test. I've got 2 questions in mind: How can I achieve the thing I'm aiming for? Should I change to the activity's end event? But then I would need to use a custom Hibernate Query since I have no criteria to be used for the HistoryTaskQuery. And is this a bug or just a specific behaviour of jBPM? An unwanted or wanted one? If this is unwanted and the task should to be found already in the task could this behaviour be changed?

[jboss-user] [jBPM Users] - Advice regarding complex proccess modeling
Hello, I've pointed out already some questions a few days ago, but our team decided to take it back to the drawing board, because we're a bit confused, so we were wondering if anyone more experienced could help. We are currently trying to implement a document authorization and reviewing system, using jBPM. We are having some trouble defining the flow however. What seems difficult to us is how to: - Control the flow of the document through the organization. The document is read, forwarded to one or several people, then some of those people can forward the document too for further reading and commenting. We're having some trouble defining this flow. - The document can be read by several people at the same time or an order can be defined, meaning that from a group of 3 people, for example, (X, Y and Z), only Y can read the document after X and Z can read after Y. How can we define this flow as well? The main problem is that we can't tell in advance what people will be treating the document and if they will be doing it on a sequential or parallel way. what we now are the activities we want to perform on the document and in which sequence they occur. Modeling all the different routes a document may take, combining all the activities we want to perform, doesn't seem like a good approach to the problem. This would result in a huge process definition or many process definitions creating a maintenance and usability problem. Is there a design pattern to help solve this situation? Could someone more experienced give us some hints? Thank you very much.

If you got issues then just like everyone had to do in the past you have to report the issues with information about what goes wrong - i.e. the stack traces and what part of hibernate tools you are actually using when generating hbm.xml files ? Is it the code generation or the wizards ? The new hbm.xml files wizards have been going through major new features and thus you might see issues if you are using the milestones and nightlies - if you want 100% stable then use the stable releases! But please, give some more details and we will fix them. i.e. I just tried with M4 and I could not trigger a stackoverflow error - so please give some more details. anonymous wrote : | Before some Fan Boys comment back.

I use the tools constantly and sure I know of some issues and I reported them all - but none where stopship issues. If you found some, please take the time to report the issues. Note, i've been on vacation for 2 weeks so maybe you already did report them in jira - if yes, then please post the links here.

[jboss-user] [jBPM Users] - jBPM BeanShell: fail with osgi classpaths
Good day, Currently I'm working on a RCP project with jBPM 3. At this very moment I'm stuck while trying to execute a process. The processDefinition.xml starts executing and at a certain moment, when it reaches a part where a Script object is started, a DelegationException is thrown. Prior to this exception, I noticed that BeanShell did not seem to be able to resolve the OSGi classpath I use where certain source/config files are located. Debugging the code learns that the cause is located somewhere in the integrated BeanShell code (can't tell where exactly, as I don't have the source code available); it seems that BeanShell does not use proper classpaths (confirming OSGi standards), while my RCP based project does. As far as I know, BeanShell does 'something' with the classpaths/classloaders which seemingly affects the process in a negative way. Can anyone suggest a way to make jBPM/BeanShell understand how to use the proper classpaths or other, if the probable cause does not concern the classpaths/OSGi aspects, possibility? Thanks for the effort!

[jboss-user] [jBPM Users] - Re: Running demo.setup.jboss Problems under MySQL
I think there's something wrong with the build.xml. When running ant -Ddatabase=mysql demo.setup.tomcat, during the ant target install.jbpm.to.tomcat, there's a task that set database.driver.destination.dir property, then run target internal copy database driver. But when running demo.setup.tomcat, no such property is set, so the mysql-connector-java.jar is copied to the current directory where ant script running. This leads that no mysql driver is installed to JBoss server, so leads to ClassNotFoundException. So is this a problem with the build.xml script?
