    Description

      With a bean config like this:

      <session>
<ejb-name>HelloBean</ejb-name>
<remote-binding>
<jndi-name>HelloBean/http</jndi-name>
<client-bind-url>
          http://${jboss.bind.address}:8080/unified-invoker/Ejb3ServerInvokerServlet/?return-exception=true
</client-bind-url>
</remote-binding>
<remote-binding>
<jndi-name>HelloBean/https</jndi-name>
<client-bind-url>
          https://${jboss.bind.address}:8443/unified-invoker/SSLEjb3ServerInvokerServlet/?return-exception=true
</client-bind-url>
</remote-binding>
</session>

      and client code like this:

           51     Properties p = new Properties();
     52     p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.HttpNamingContextFactory");
     53     p.put(Context.PROVIDER_URL, "http://localhost:8080/unified-invoker/JNDIFactory/?return-exception=true");
     54     p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
     55     Context ctx = new InitialContext(p);
     56 
     57     //Hello bean = (Hello) ctx.lookup("ProxyFactory/helloWorld/HelloBean/HelloBean/http");
     58     Object o = ctx.lookup("HelloBean/http");

      there is sometimes an attempt to connect via the HTTPS URL, which indicates the clustered proxy sees the https binding as a 2nd target.

      Stack trace showing the attempt to use HTTPS:

      test:

          relates to

          Bug - A problem that impairs or prevents the functions of the product. JBPAPP-11155 Clustered stateful EJB proxy confusing with multiple remote bindings

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
