[JBoss jBPM] - Getting comments through command object ?
by lblaauw
Hey all,
Does anybody have any experience in getting the comment entries through the use of a getTaskInstance command or getprocessInstanceCommand ? I am using these through the command EJB and this will throw a lazy init exception since the collection of Comments is lazy getting it wont work through the EJB interface since obviously the connection through hibernate and the DB is allready gone when you receive the taskinstance of processinstance...
We could ofcourse modify the sources so this collection is not lazy, but i would rather have the option, like with variables, to set a switch on the command object to retrieve the comments or not and then have the command EJB deal with it.
Any solutions greatly appreciated...
Thanks and greetings,
Leo de Blaauw

by abhinav_solan
Hi I have been trying to enable clustering on 2 machines on JBoss 3.2.8SP1( I cant move to JBoss 4 as my application is configurable for 3.2.8SP1 only) but the 2 machines are not able to discover each other, other machine is showing.

11:23:10,526 INFO [DefaultPartition] Other members: 0
can some one please help me in this ...
