2005-02-24 Thread dragon_jdh
thanks a lot, I will try it immediately.

BTW: is there a way to do RMI tunneling on JBoss? 
I know JProxy can do it, but I want to find other ways. thanks

[JBoss-user] [Persistence CMP/JBoss] - Re: dead lock

2005-01-17 Thread dragon_jdh
I did some modification as following:

1: modify jboss.xml, add one container configuration as following:

container-configurations
container-configuration extends=Instance Per Transaction CMP 2.x 
EntityBean
  container-nameOptimistic CMP EntityBean/container-name
  
locking-policyorg.jboss.ejb.plugins.lock.JDBCOptimisticLock/locking-policy
  commit-optionB/commit-option
/container-configuration
  /container-configurations

then shift the special bean to this configuration.

2: configure locking policy for the special bean in jbosscmp-jdbc.xml.

load-groups
 load-group
   load-group-namewo/load-group-name
   field-namestatusDicId/field-name
   field-nameplannedStartDateTime/field-name
 /load-group
  /load-groups

optimistic-locking 
   group-namewo/group-name  
/optimistic-locking


3: add synchronize in some places which shouldn't be concurrent invoking. 

then my system passed the test of loadrunner.

[JBoss-user] [Persistence CMP/JBoss] - Re: dead lock

2005-01-12 Thread dragon_jdh
I change the bean to 'instance per transaction...',  and add synchronize in 
some place, the deadlock disappear again. but I got following exception:
java.util.ConcurrentModificationException
...

I found the configuration for 'instance per transa..' is nolock, and also I 
change the commit option to A. because in our codes, all update operations are 
done by entity bean.

what shall I do?  thanks.

[JBoss-user] [Persistence CMP/JBoss] - how to configure get find method independently?

2005-01-12 Thread dragon_jdh
May I configure find  get methods to no lock, set methods to pessimistic lock?

in standardjboss.xml, we can configure the locking policy, but it's for all 
ejb. Can I configure for special methods?

[JBoss-user] [Persistence CMP/JBoss] - dead lock

2005-01-10 Thread dragon_jdh
jboss3.2.3  sql server 2000

I have a timertask, run in background regularly. it will visit an entity bean, 
suppose A. 

And also there are other places visit that bean. 

all the methods are 'required' configuration. the isolation level is 
pessimistic 

now I often met deadlock exception. 

How do I resolve this problem?
