the package of complex parameters needs to be specified per java package within a package-info.java file: see http://www.jboss.com/index.html?module=bb&op=viewtopic&t=103352 JBossWS 1.2.x generates buggy wsdl files, though unless http://jira.jboss.com/jira/secure/ManageAttachments.jspa?id=12335583 is fixed (scheduled for version 2.0.0 now). Although the wsdl files are not correct, clients generated with .net 2.0 and axis 1.4 tend towork at least when the parameter typ names are unique without looking at their package names. The client stub generators are intelligent enough to remember the correct package names then. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045790#...
