I am using Jboss 4.0.4RC1 and have created a simple stateless session bean
using ejb3. Remote access using the default socket transport works fine but I
cannot get servlet trandport working.
I have added this to ejb3.deployer/META-INF/jboss-service.xml
| <mbean code="org.jboss.remoting.transport.Connector"
| xmbean-dd="org/jboss/remoting/transport/Connector.xml"
|
name="jboss.remoting:type=Connector,transport=servlet,name=Servlet,handler=ejb3">
| <depends>jboss.aop:service=AspectDeployer</depends>
| <attribute
name="InvokerLocator">servlet://${jboss.bind.address}:8080/servlet-invoker/ServerInvokerServlet</attribute>
| <attribute name="Configuration">
| <handlers>
| <handler
subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler>
| </handlers>
| </attribute>
| </mbean>
|
I have added servlet-invoker.war to the deploy directory. This contains the
following META_INF/web.xml file
| <?xml version="1.0" encoding="UTF-8"?>
| <!DOCTYPE web-app PUBLIC
| "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
| "http://java.sun.com/dtd/web-app_2_3.dtd";>
|
| <!-- The the JBossRemoting server invoker servlet web.xml descriptor
| $Id: web.xml,v 1.1 2005/06/16 21:12:48 telrod Exp $

| <web-app>
| <servlet>
| <servlet-name>ServerInvokerServlet</servlet-name>
| <description>The ServerInvokerServlet receives requests via HTTP

| </init-param>
| <load-on-startup>1</load-on-startup>
| </servlet>
| <servlet-mapping>
| <servlet-name>ServerInvokerServlet</servlet-name>
| <url-pattern>/ServerInvokerServlet/*</url-pattern>
| </servlet-mapping>
| </web-app>
|
|
My session bean is declared as:
|
@RemoteBinding(clientBindUrl="http://localhost:8080/servlet-invoker/ServerInvokerServlet";,
jndiBinding="mailserver.TestStatelessEJB.servlet")
|
The client program is:
| Properties p = new Properties();
| p.put(
Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
| p.put( Context.URL_PKG_PREFIXES,
"org.jboss.naming:org.jnp.interfaces" );
| p.put("java.naming.provider.url", "localhost");
| ctx = new InitialContext(p);
| TestStatelessRemote r = (TestStatelessRemote)
ctx.lookup("mailserver.TestStatelessEJB.servlet");
| r.remove(10);
| r.create(10,"hello from testEJB");
| System.out.println(r.getText(10));
| .....
|
|
JNDI lookup works ok but when r.remove is executed the following exception is
thrown:
| org.jboss.remoting.CannotConnectException: Can not connect http client
invoker.
