Subject Re: RE : active mq on tomcat (configuration)
Date Tue, 14 Aug 2007 06:58:29 GMT

Hi Suchitha Koneru,

First, thanks you for your reply ! You give me a very good explanation.
I post an other message in this list "Using ActiveMQ into Tomcat".
Could you read it and reply me if it's possible or not ?

I will try to play with your instruction below, and give feed back.
Regards,

Denez
