As far as I can remember, yes I did, but I just checked the build.xml file, seems it should be copied whatever version of JBoss AS. Anyway, this can be a mistake on my part. I used the JBoss 1.2 SP1 and seems the wsrunclient.bat is there now. Btw, stax-api.jar and wstx.jar are not present in JBoss 4.0.5 and JBoss 4.2 CR1. anonymous wrote : 2.) What exactly does castor send? Why don't you use a JBossWS client in conjunction with the Dispatch API? The actual xml string. OK, will check dispatch. anonymous wrote : The last point is a JAXB issue. Make yourself familiar with the way JAXB works. Ah yes, JAXB 2.0 is really something, that is why I wanted to use it. But in this case, seems JBoss should have handled unmarshalling and marshalling properly. I just followed the guide and was able to send messages properly. Problem was that they were not unmarshalled properly on receiving end and not marshalled properly on response side. Btw, I turned on logging in debug mode, and didn't see any problems. Well actually, no errors were thrown. anonymous wrote : Please keep in mind that community support is delivered at free will and should actually be driven by JBossWS users. Yes, you have a good point there. Maybe I will take a look at the source if I had time. Anyway, using axis right now since I really need to make it work. Will migrate to jboss if I finally solve the problem. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027589#...
