1: Search BETTER: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=70723 (just by using the term webservice)
2: Yes it is. What is calling a webservice different then clling some java code (besides transactions, reliability etc)
Thanks alot Ronald, It did help, although I am now facing an error when calling the ws :)
I dont know how you search, because even if I search with a string like 'Invoking a web service', it came back with more than 100 pages, I browsed through 5 to 6 of them but to no avail.
