This
is not a bug in Jboss, you should close your connections
for
them to be released back into in the pool. The javadoc for
java.sql.Connection.close()
says:
"Releases a Connection's database and JDBC resources immediately instead of
waiting for them to be automatically released". automatic release will happen
when the object is garbage collected...
In
general, you should always be careful with your
resources....

Hi! I've discovered the problem. At some point of
view, is a JBoss bug too.
What I'm doing wrong is that I never close
ResultSet, Statement and Connection. At other side, after reaching limits from
my Sybase SQL Server (25 connections), JBoss just freeze in responding any
client (neihter Stateless, Statefull nor Entities)...
Thanks,

Subject: [JBoss-user] Error in
2.4.1
I'm using JBoss 2.4.1 with Tomcat 3.2.3. I've a
simple StatefullSession bean that, in some places acts as stateless
(offering to my pages some services).
I'm using only a method - List
getCustomersByName( String name ) - that returns an ArrayList of javabens
containing some data from my customers. The sequence is Search Page ->
submit -> getCustomersByName -> Results Page. If I go back to Search
Page and repeat process 20 or more times, JBoss giveme following
error:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
javax.transaction.TransactionRolledbackException: Application Error: tried to enter Stateful bean with different transaction context; nested exception is:
