    Native Netty based server / Embedded Tomcat

    Eugene Adams Newbie



      I have a custom server which relies heavily on threading(with Netty as IOLayer).  Now this server has run as an independent server as a client of JBoss for a few years, but I am toying around with embedding this server inside JBoss, same as the native Tomcat service.  What do I have to look out for and where do I start?  I have deployed the service as a .sar, but it gives me exceptions like the following after I try to hit the JMX console :


      2010-06-25 09:35:09,401 ERROR [org.apache.coyote.http11.Http11AprProtocol] (http-jmx.my.server.domain%2F192.168.1.100-8080-1) Error reading request, ignored

              at java.nio.DirectByteBuffer.<clinit>(DirectByteBuffer.java:33)
              ... 7 more



      The error is on Bits.java:592 :

      static boolean unaligned() {
          if (unalignedKnown)
              return unaligned;
              PrivilegedAction pa
              = new sun.security.action.GetPropertyAction("os.arch");
              String arch = (String)AccessController.doPrivileged(pa);
          unaligned = arch.equals("i386") || arch.equals("x86") || arch.equals("amd64"); <<<<<<<<<<<<<<<<
          unalignedKnown = true;
          return unaligned;



      How do I configure my service in jboss as a native embedded application and ... why is it giving this error?
