Hi
I have a question regarding locking policy in jboss. I am using an oracle
database. Now what I am doing is, I am updating a set of records from oracle
using normal JDBC Connection (using a datasource of course), from an MDB.The
update operation takes some time since there are a number of records. Meanwhile
i m trying to update the same set of reocords from another thread,(which can be
a java program or a normal sql plus window) but this updation wont happen
unless the transaction in the MDB completes. So for this(since i know the
default locking policy is Pessimistic), i made the locking policy as
Optimistic, and I assume that the above scenario should work.But this does not
work. Can any one explain why this is not working. I have pasted my jboss.xml
below
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.0//EN"
"http://www.jboss.org/j2ee/dtd/jboss_3_2.dtd";>
