@Id
@GeneratedValue(strategy = SEQUENCE, generator = "SEQ_ACE_ACTIVE_CI")
@SequenceGenerator(name = "SEQ_ACE_ACTIVE_CI", sequenceName = "SEQ_ACE_ACTIVE_CI", allocationSize = 500)
I'm running on JBOSS 4.2.3.GA for java 6
in my entities I connect between a real DB sequence and the Id field in the following way
@Id
@GeneratedValue(strategy = SEQUENCE, generator = "SEQ_NAME")
@SequenceGenerator(name = "SEQ_NAME", sequenceName = "SEQ_NAME", allocationSize = 500)
I put the allocation size as 500 since after some performance tests i run i saw that prevents it from going to the DB for each insert and doing
select seq.nextval from dual
- I'm using Oracle , and the above is probably not the exact syntax, just the general idea.
the thing is that although my sequence is defined with an initial value of 1000 in the DB is see that all my generated entities start with id 500000 and each time I restart my server it jumps in 500 and in the meanwhile if I look at my sequences I see that the don't progress above the initial value of 1000.
I feel stupid just asking this question, but if you can just explain to me what's missing in my understanding or point me to where this was already discussed I'll be grateful, since I couldn't find the explanation on my own. :-/

Hi Deepak,
Did you get your answer about creating sample web application and using JBPM4 in it?
I'm using user doc from jboss jbpm4 and able to run jbpm-console application but they have target to create user-webapp in build.xml file under >install
directory and I'm able to build sample user-weapp which creates user-webapp under \jbpm-4.4\install\generated\user-webapp .But not sure how to deploy on jboss5.1.0 and i've noticed that user-webapp folder doesn't have web.xml.So that could be the reason ,it's not deploying on jboss properly.
If you have done this sample user-webapp deployment successfully or any other sample web app using jbpm4 in it then please let me know.
Thanks,
Anand

[JBoss Tools] - JBoss tools 3.2B1 sometimes doesn't deploy classes in web module

--------------------------------------------------------------
Hi,
I'm using JBoss Tools 3.2 beta 1 with Eclipse 3.6.1 on Ubuntu 10.10 (64 bits) on JDK6U21. I have an EAR project that is deployed to JBoss AS 5.1. This initially works correctly, but after I stop the server, make some changes to my files, pull in new changes from Mercurial etc I restart the server.
I then get class not found errors, and when I inspect the deployment in JBoss AS it seems that there are most classes are missing in the web module's WEB-INF directory. Strangely however, there are some classes that are deployed and for some classes that are missing, the package folder is there but it's empty.
The "Server Log" view for the JBoss 5.1 Runtime Server mentions under the Publishing node:
1 files modified in module my_main_ejb 31 minutes, 2 seconds ago
81 files modified in module my_main_web 31 minutes, 2 seconds ago
The 31 minutes exactly corresponds with the time I started the server and the classes where missing. The Modified time of the files that are present in the WEB-INF/classes also corresponds with this.
I did notice that there are some suspect events in the log, but these are dated a couple of hours back where the deploy did work. It is:
No publisher found for module DeletedModule[saxon9.jar,org.eclipse.jst.jee.server:/binary:/home/myuser/workspace/my_main/libraries/saxon9.jar.
This did happen a couple of time before, and I could fix it by closing and re-opening the EAR and it's associated web and EJB projects and cleaning, restarting, etc (don't know exactly in which order). I remember a very similar bug in JBoss tools 3.1 where sometimes only the most recently touched files where deployed.

[JBoss Remoting] - Encrypt SSL KeyStorePassword in remoting-sslbisocket-service.xml

"Encrypt SSL KeyStorePassword in remoting-sslbisocket-service.xml"

--------------------------------------------------------------
Hello,
I am using jboss 5.1 GA.
I would like to encrypt the ssl keystore password in the remoting-sslbisocket-service.xml of jboss messaging. This xml contains the following mbean configuration. This xml of jboss messaging is using the org.jboss.remoting.securirity.SSLSocketBuilder mbean of jboss remoting. From what I can see here http://docs.jboss.org/jbosasremoting/docs/api/org/jboss/remoting/security... http://docs.jboss.org/jbosasremoting/docs/api/org/jboss/remoting/security... there is no way to encrypt the keystore, trustsore passwords. Am I correct? Has anyone tried extending the SSLSocketBuilder class to provide such functionality? I am considering doing this myself.
Thanks,
Nikos.

[jBPM] - JBPM 4.4 - exception recovery

"JBPM 4.4 - exception recovery"

--------------------------------------------------------------
I have a Spring based web application with JBPM embeded.
I defined a workflow, that have a task followed by 3 custom activities:
activity1 - calls webservice
activity2 - sends email
activity3 - sends JMS message
At some point my application calls taskService.finishTask, and those activities will be executed.
What I need, is in a case of error (let say SMTPserver is unreachable or web service is not up):
1. Activity should be retried until it succeed (I understand that a lot of logic could be suggested around this, like retry count, notifications, etc, but I am simplifying this on purpose)
2. Activities that succeeded should not be repeated, i.e. if activity2 fails, activity1 should not be executed again (and this is what happens now if any of those activities throws an exception - I guess it has to do with transaction being rolled back)
So my question is - Is there an easy or at least standard way of doing this in JBPM?
