Did anyone try the instruction given at http://www.jboss.org/community/docs/DOC-9632 to invoke EJB over HTTP using JBOSS AS5? I am getting ServiceUnavailable Exception when following the steps below. Server Side Setup Step 1. Grab a copy of JBoss AS 4.2.x+ or JBoss EAP 4.2.x/4.3.x+ and create a new server configuration (based on /default). Step 2. Go to deploy/http-invoker.sar/invoker.war/WEB-INF/classes/ directory and ZIP up the classes into a JAR called jboss-http-naming.jar. Put this jar in the server's lib directory so that both the legacy and unified http invoker share these classes. Step 3. Follow instructions in SSLSetup to generate the necessary SSL certificates depending on your security requirements and enable HTTPS connector. Step 4. Take the attached http-uinvoker-v1.sar.zip file and unzip it in the deploy/ directory: View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4202997#...
