Re: Re: Re: Deploying AXIS2 (1.5) on JOnAS 5.1.5

Nice to know that you finally had your app working on JOnAS 5.1 :)

As a side note, I will add that <java2-delegation-model> is *not* a 
magic solution for avoiding classloader conflicts.
It's only way to express that you prefer to load your libs from your app 
first (and then from system) or reverse.
In some cases it can work, and for others not.

BTW, I think that, generally speaking, APIs should be avoided in the 
application.
