[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Servlet transport problem

[gaohoward]

Hi, I can't get the servlet transport working. I configured a new connection factory that using servlet transport, like:


  |    <connection-factory name="ServletConnectionFactory">
  |       <connector-ref connector-name="netty-servlet"/>
  |       <entry name="ServletConnectionFactory"/>
  |       <entry name="/ServletConnectionFactory"/>
  |       <entry name="/XAServletConnectionFactory"/>
  |       <entry name="java:/ServletConnectionFactory"/>
  |       <entry name="java:/ServletConnectionFactory"/>
  |    </connection-factory>
  | 

and the netty-servlet configuration is like


  |       <connector name="netty-servlet">
  |          <factory-class>org.jboss.messaging.integration.transports.netty.NettyConnectorFactory</factory-class>
  |          <param key="jbm.remoting.netty.host" value="localhost" type="String"/>
  |          <param key="jbm.remoting.netty.port" value="8080" type="Integer"/>
  |          <param key="jbm.remoting.netty.useservlet" value="true" type="Boolean"/>
  |          <param key="jbm.remoting.netty.servletpath" value="/jms-servlet/JBMServlet" type="String"/>
  |       </connector>
  | 

After I deployed the war that contains the servlet (web.xml), I run my simple example, and it got exception in create connection, here is the output:

  |      [java] ------------uri: http://localhost:8080/jms-servlet/JBMServlet

Looks like a netty problem, I have no idea so far. Anybody can give a hint? thanks.
