[jbosstools-dev] Re: [Soa-tools-list] Example of why consistent jar usage is important

Denny,

Max and I discussed this, and for the time being (this release), we'd
just like to move the ESB cp container ahead of the AS cp container on
the project classpath. This will allow override libs in the ESB
classpath container to be loaded first. 

Is this possible, and, if so, can you take care of this?
