Currently we are patching JBoss 4.0.5 with the EJB 3.0 RC6 PFD patch found here: http://sourceforge.net/project/showfiles.php?group_id=22866&package_i... I would then like to make sure we can leverage JAX-WS, so I'm following the install guide of jbossWS at http://jbws.dyndns.org/mediawiki/index.php/Install_JBossWS One of things I noticed is that the first patch removes the jbossws14.sar and adds a file (not a dir) of "jbossws.sar." Then the jbossws ant install for jboss4.0 tries to remove either of the dirs "jbossws.sar" or "jbossws14.sar" and replace it with it's version of the jbossws.sar. The install fails here since the first patch added a file not a dir - an easy fix to the install.xml of the jbossws with the added line fixes this.. <delete file="${jboss40.home}/server/${jboss.server.instance}/deploy/jbossws.sar" /> I'm wondering is there are any other issues to be aware of following this procedure of patching 4.0.5 with the EJB3.0 patch and then installing jbossws? I guess we could just be safer and use the jems installation of 4.0.5 and then install jbossws. (I just know we had things working pretty well with the patched version, so I'm not wanting to change too much at once.)
