Dear all, According to the EJB specification using threads inside EJB applications is disallowed because Thread management should be managed by the EJB container. Please find the reference below: http://java.sun.com/blueprints/qanda/ejb_tier/restrictions.html What about Web Services? Can we use threads inside Web Services? Should we do it? Is there any kind of restrictions regarding the use of threads inside web services? Thanks, Joshua View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4170590#...
