--------------------------------------------------------------
I am trying to install jBPM 5 using my existing installations for JBoss7 and Eclipse Indigo. I have modified the build.properties file to point at my existing Eclipse installation and removed all mention of JBoss5.
In the installation documentation for jBPM the following instructions are presented:
h3. Installing
In the install dir, run installation script:
+ant install.guvnor.into.jboss+
+ant install.designer.into.jboss+
+ant install.jBPM-gwt-console.into.jboss+
+ant install.jBPM-eclipse.into.eclipse+
+ant install.drools-eclipse.into.eclipse+
The problem is that the last two tasks do not exist in the build.xml file. I have found a task called +install.droolsjbpm-eclipse.into.eclipse+ and another called +install.jBPM.runtime.+ I have run them both, as well as +install.demo.eclipse,+ but still neither the Guvnor or Console are accessible.
It would be great if someone could update the jBPM5 installer documentation. It seems that most people would already have both JBoss and Eclipse installed independently before they choose to install jBPM5. I have tried every flavor of JBPM5 installation--full/comprehensive and pieces parts--but I remain unsuccessful in getting access to the Guvnor and Console.
Ready to give up entirely on jBPM and head over to take a look at Intalio....

[EJB3] - JPA Sequence generated value is different from Oracle sequence nextVal

The default sequence generator of JPA (SequenceHiloGenerator with allocationSize=50 ) generates a sequence value which is different from the corresponding oracle sequence's nextVal.
We have used allocationSize=50 for performance improvement but this creates problem by generating values which are not matching with the corresponding sequence values. In my case if nextVal of the sequence is 250 then the value generated by the JPA is far more than 250. I want the generator behaviour to return database sequence values while giving me performance enhancement by calling database sequence only once for every 50 inserts.
I know setting allocationSize=1 would generate value same as database sequence nextVal but in this case it makes select query for each insert to the table. I want to get rid of the selects for the inserts and thats why I moved on approach for HiliGenerator using allocationSize=50 but in this case facing problem of generated value not having in sync with the database sequence.
I would appreciate if anyone suggest a solution for this problem.
Regards

[JBoss Tools] - Deployment problem with Eclipse + JBoss Tools

Ok, I've been on this for like 10 hours now, and neither Google nor my attempts to find a solution have helped. So here's the problem, I hope somebody can help, or at least tell me whether this should be reported as a bug or not.
I recently installed Eclipse 3.7.2 on Mac OSX 10.7.3 (Lion), together with the latest JBoss Tools package. As I am new to JBoss Tools (and Apache Maven that it's using in my projects) I decided to get familiar with it before going on with something serious. So I created a new JBoss Central/Spring MVC Project. After that I added a server instance (JBoss AS 7.1.1) inside Eclipse, and deployed this unmodified project template using the Project/Run As/Run on server way. This works perfectly! However, if I for some reason decide that I would like to undeploy the project, and then deploy it again (i.e. undeploy using JBoss Management, then delete the exploded war-dirs, restart the server, and finally deploy as described above), I end up with everything being deployed, EXCEPT for everything that is in the webapp directory (the one that's created by default in this project template). As a consequence, the web application won't run anymore.
Now this is what I've tried without any success:
- Restart Eclipse;
- Delete every possible file in the JBoss AS directory, that could have something cached inside it;
- Committed the whole project tree into GIT, in order to check whether Eclipse changes some config setting (it doesn't);
- Various combinations of the above, together with a lot of other not-remembered steps ...
