I'm trying to code with low coupling to anything .. but here's what I'm using.
JBoss 3.0.2 w/Strits 1.1 with MS SQL 2000 as a back-end. The code I'm asking for would having nothing to do with this. Just a snippet from the sturts-config.xml and the jsp that utilizes LookupDispatchAction. -----Original Message----- From: kiuma [mailto:[EMAIL PROTECTED]] Sent: September 20, 2002 9:45 AM To: Struts Users Mailing List Subject: Re: [kiuma ] LookupDispatchAction ... Do u use jboss + struts + postgres , under linux. If so I could share my code with you. I'm planning to do this. Part deploy undere lgpl (or similar) as a case study, Part as a commercial app (not yet implemented. Would you like to use jboss I can help you to start if you are not familiar with.
