There is a problem with the database pools (at least in the jca version, however I think the same code is used in the XADataSourceLoader version) that lets some requests for a connection wait forever while other requests get processed immediately. I'm not sure if there is an easy way to determine if this is the problem you are having.
I'm working on replacing the pooling code for 3.0. david jencks On 2002.02.12 06:22:51 -0500 Mahesh Agarwal wrote: > Hi All > > I am using JBoss-2.4.1_Tomcat-3.2.3.
