1. Re: Obtaining a newly added POJO in TreeCacheAop
ben.wang Nov 7, 2005 6:54 PM (in response to motormind)Can't getObject do the trick. It is only read lock on one paticular node and it is quick (since it will just return the object instance).

No. When I try a getObject(), I get a stacktrace like this:javax.transaction.RollbackException at org.jboss.cache.transaction.DummyTransaction.commit(DummyTransaction.java:67) at org.jboss.cache.transaction.DummyBaseTransactionManager.commit(DummyBaseTransactionManager.java:60) at org.jboss.cache.aop.TreeCacheAop.endTransaction(TreeCacheAop.java:483) at org.jboss.cache.aop.TreeCacheAop.putObject(TreeCacheAop.java:373) at nl.motormind.server.TblServerRmt.initialize(TblServerRmt.java:407) at nl.motormind.server.TblServerRmt.<init>(TblServerRmt.java:209) at nl.motormind.server.TblServer.main(TblServer.java:18) at nl.motormind.test.StartAll.main(Unknown Source)11:44:51,468 Feed node created: /feeds, object null [ Thread-32] INFO titaan.tbl.server.TblServerRmt 08 Nov 2005 11:44:51,468 org.jboss.util.NestedRuntimeException: TreeCacheAop.endTransaction(): ; - nested throwable: (javax.transaction.RollbackException) at org.jboss.cache.aop.TreeCacheAop.endTransaction(TreeCacheAop.java:490) at org.jboss.cache.aop.TreeCacheAop.putObject(TreeCacheAop.java:373) at nl.motormind.server.TblServerRmt.initialize(TblServerRmt.java:407) at nl.motormind.server.TblServerRmt.<init>(TblServerRmt.java:209) at nl.motormind.server.TblServer.main(TblServer.java:18) at nl.motormind.test.StartAll.main(Unknown Source) Caused by: javax.transaction.RollbackException at org.jboss.cache.transaction.DummyTransaction.commit(DummyTransaction.java:67) at org.jboss.cache.transaction.DummyBaseTransactionManager.commit(DummyBaseTransactionManager.java:60) at org.jboss.cache.aop.TreeCacheAop.endTransaction(TreeCacheAop.java:483) ... 5 more

motormind Nov 8, 2005 8:58 AM (in response to motormind)I tried to postpone reading the object until I get the first Modification-event, but then I get this stacktrace:

4. Re: Obtaining a newly added POJO in TreeCacheAop
motormind Nov 10, 2005 6:48 AM (in response to motormind)Does anyone at JBOSS have a clue about what is going wrong? I have been reporting these kinds of issues for months now and am really starting to get pressed for time, since my project needs to get finished... so any kind of input would be appreciated!

5. Re: Obtaining a newly added POJO in TreeCacheAop
ben.wang Nov 10, 2005 10:29 PM (in response to motormind)Sorry, I'd like to help but I don't have a clue unless you can give me a sample test case to run.
Like I mentioned, we have numerous junit test cases that test getObject call. You can verify it yourslef from our 1.2.4 distro.

brian.stansberry Nov 11, 2005 12:27 AM (in response to motormind)Ben,
Sorry, at this time of night I'm being lazy and just posting instead of looking at the code, but is the problem possibly that he's getting the notification early in the process of breaking down the object into tree nodes, and calling getObject() at that point is interfering with the process? -
7. Re: Obtaining a newly added POJO in TreeCacheAop
ben.wang Nov 15, 2005 1:07 AM (in response to motormind)Yes, that is possible. But I need a use case to see this otherwise it is difficult for me to troubleshoot.
Motormind, can't you cook up a dummy use case?
