    JMXInvokerServlet invoked by a standalone program

    msadoun Newbie

      Hi,

      I've been searching in different forums, i can?t found anybody who already met the following issue:

      I got connection refused when i invoke the JMXInvokerServlet remotely from a standalone application in JBoss/Tomcat bundle 4.0.5 behind Apache 2.0 using mod_jk 1.2.20.

      I need to access JBoss ejb tier through http avoiding rmi calls. The following tests j've made run locally on Windows xp environment , and remotely on Redhat Lunix.

      The application is downloaded and deployed through java Web Start and uses JNDI over http provided by http-invoker.sar to access the server. Within jnlp file, all resources come from the same server.

      I?m using mod_jk configuration exactly as described at http://www.jboss.org/wiki/Wiki.jsp?page=UsingMod_jk1.2WithJBoss and my uriworkermap.properties contains:

      /invoker=loadbalancer
      /invoker/*=loadbalancer


      The application works fine on the localhost with the following jndi.properties:

      java.naming.factory.initial=org.jboss.naming.HttpNamingContextFactory
      java.naming.provider.url=http://localhost/invoker/JNDIFactory
      java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

      and with the jboss-service configuration snippet code of the HTTP invoker service:

      <attribute name=InvokerURLPrefix>http:// < /attribute>
      <attribute name=InvokerURLSuffix>/invoker/JMXInvokerServlet < /attribute>

      Also, every thing goes well when accessing directly and remotely JBoss/Tomcat by shunting Apache+mod_jk using:
      - java.naming.provider.url=http://www.mydomain.com:8080/invoker/JNDIFactory
      and
      - <attribute name=InvokerURLSuffix>:8080/invoker/JMXInvokerServlet < /attribute>

      But i got connection refused when accessing JBoss/Tomcat remotely through Apache, and mod_jk with the following:
      - java.naming.provider.url=http://lwww.mydomain.com/invoker/JNDIFactory
      and
      - <attribute name=InvokerURLSuffix>/invoker/JMXInvokerServlet < /attribute>

      see message below.

      I can't figure out what's wrong or missing, any help will greatly be appreciated.

      Thanks.
      Alain
