Re: [jboss-user] [Beginner's Corner] - Error while booting Jboss 5.0.1. Can anybody help?

To view the discussion, visit: http://community.jboss.org/message/559557#559557 -------------------------------------------------------------- Hi, you have an ear file "1.ear", which contains a whole lot of EJB jars, one for each bean, I assume? It seems you have some kind of dependency beetween the beans, but JBoss cannot detect the correct deploy order, because they are split beetween jar files. Why this? You can place all EJBs in one single EJB jar file, and this will avoid this dependency problem. If this is not possible, you might take a look at the JBoss specific "@Depends" annotation, but I fear this one will not work cyclic dependencies.

Re: [jboss-user] [jBPM Development] - History details

I think the comma separation is enough for fork and forkeach, because these outgoing transitions will be created at the same time. But for the JoinActivity, if we want to record full information about when each of transition arriaved on it. We have to record each record per transition. What do you think about it? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/559540#559540] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Only question is how/what shall be saved. The issue is that we have multiple transition names to be saved for both fork and for each and multiple transition names reaching join. So there are few options: 1. we save one record for the activity saying when it happened and number of transitions taken 2. we save one record for the activity saying when it happened and names of the transitions as comma separated values 3. we save one record per transition taken for fork and for each, for join we save one record for each incoming transition 4. introduce new table for transition names that will be joined with history for activities Comments, ideas? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/559531#559531] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

HuiSheng Xu [http://community.jboss.org/people/rebody] replied to the discussion "History details" To view the discussion, visit: http://community.jboss.org/message/559529#559529 -------------------------------------------------------------- Hi Maciej, In my opinion, it would be better to save all of informations about fork and join, whatever which branches are chosen to contien or which branches reached it or complete join to continue. Because we want to use history records to display the route of the proces instance as video or annimation or something just like these. Now we have to guest when the fork or join reached. It is really hard to guest these information without history records. I think it is maybe a little hard to achieve these features on current PVM. Just after we support dynamic fork with foreach and M of N fork, and join with multiplicity attribute. What are you thinking about it? Regards. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/559529#559529] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

I have some doubts about our dear Jboss ESB, i´ll be very grateful if you could answer them: * What kind of signaling protocol is used? is it based on IP-Multicast? or does it have other kind of protocol? * What about discovery? is it based, as well, on IP multicast? does it use a predefined peer list? or another mecanism? and what is more important, can i connect more nodes without stopping the other nodes? Thank U beforehand!
