Hi,

Its in deploy directory , depending on which database u are using. if its hypersonic the default database then file name is hsqldb-service.xml

u will find the settings in
<mbean code="org.jboss.resource.connectionmanager.JBossManagedConnectionPool" ....

for max,min no. of connections.

Hi,

try again by changing the Criteria attribute in
<mbean code="org.jboss.resource.connectionmanager.JBossManagedConnectionPool" ....

to ByNothing

I just know it has effect on connection pool since it distiguish between diff. connections according to this criteria.

Hiii,
I am using default directory for deploying.But i think the problem is with connection.B'coz the exception in the server is :

2004-10-20 11:48:25,703 ERROR [STDERR] java.sql.SQLException: No operations allowed after connection closed.

Connection was closed explicitly by the application at the following location:

Is it because of not closing the connection properly??

With lots of thanks,
