I am trying to deploy my application but when JBoss SAX Parser try to validate the web.xml it can't access the XSD's and DTD's files. This happens because I am behind a proxy server and I don't known how to configure it in JBoss. I have changed run.bat file to include the following configuration "-Dhttp.proxyHost=<my_proxy_server_url> -Dhttp.proxyPort=<my_proxy_server_port>". After that JBoss found the files but it now throws http 407 error (that means I am not authenticated). As far as I known I have the following choices to solve my problem: a) Find a way to turn off the web.xml validation; b) Change the run.bat file to include the user and pass to authenticate in the proxy server (-Dhttp.proxyUsername and -Dhttp.proxyPassword don't work). c) Or config the proxy server that JBoss should use in somewhere else. I don't known how to do none of the above. Can anyone please help me? I have already found some topics in the forum with the same problem but none of them have any replies. JBoss 5.0.0 beta1 JDK 1.6.0 Thank you! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4007074#...
