User development, A new message was posted in the thread "JBoss AS WTP server adapter removes deployment module": http://community.jboss.org/message/527150#527150 Author : henk de boer Profile : http://community.jboss.org/people/henk53 Message: --------------------------------------------------------------   Well, it was the TS (Jan) who found the entry in that file. I personally never noticed that file, but did notice that the file I just saved was made a top level deployable artifact once. I'm willing to accept that I might have made a wrong click somewhere, but if I do find how to reproduce this I'll keep you to your promise   To be able to learn for my self and to assist my team members in how to possibly prevent this from occurring I've been trying to reproduce this my self, but so far have been unsuccessful. The only thing I can really contribute is telling that it happened multiple times in just a few weeks and on very different machines. The OS X one is a fairly modest C1D 2Ghz/1.5GB, while the Ubuntu machine is a 2.66Ghz Quad core Nehalem (8 virtual cores) with an Intel X25-M SSD. At first I thought maybe the many virtual cores of the Ubuntu machine were to blame, or some race condition with the SSD, but then it also happened on my old OS X machine.   If I do find anything I'll post it here right away. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/527150#527150
