To view the discussion, visit: http://community.jboss.org/message/630187#630187 -------------------------------------------------------------- Hi, I was trying to create a new webservice in jboss AS 4.05 and jbossWS-native 2.0.3 for ejb2.1 spec. Sample ejb project made in .ear was created and when tried to deploy the same in jbossAS4.0.5, it shows below error. Any idea what is this and how to resolve? Your help is highly appreciated. Also let me know, if at all new webservices to be created for existing EJB2.0 spec, do we still need Service Interface as End point and need to specify the end-point in ejb-jar.xml?
