    Change dynamically the node selector

    Nicolas Nicolas Newbie

      Hello all,

       

      I use a JBoss EAP 6.2. I created a custom DeploymentNodeSelector class which does exactly what I want in 99% of the use cases.

       

      However there is still this 1% and that why I would like to know if it's possible to change the deployment.node.selector value during runtime.

       

      I can get it (EJBClientContext.getCurrent().getEJBClientConfiguration().getDeploymentNodeSelector()) but I didn't find if it's possible to directly modify it.

      I tried to set value during InitialContext Initialization (jndiProperties.put("deployment.node.selector", "foo.bar.MyNodeSelector");) but it does not work...

       

      I assume it's not a good practice, but it's only for any tests which have special needs and I don't want to use it in production.

       

      Any idea?

       

      Thanks in advance.

          Depends on how your client code use the API.

          How the client look like?

          You can find some examples here jboss-as-quickstart/ejb-clients at ejb-clients might be out of date in some examples.

          I suppose you need to have a look to the jboss-api sub-project.

           

          Also you might use a hack and set a ThreadLocal inside the NodeSelector to control the behaviour for tests.

            Thanks for your response,

            The examples are interesting.

             

            In fact, the context is a little bit more complex than I said precendtly.

            Indeed, my JUnit test call a remote SBSL (called EjbTest for example) which has to call another remote SBSL (EjbBusiness).

            The first SBSL can be comparated to a proxy which allows to get the "business SBSL".

             

            Finally, I think the easier solution is to use two differents DeploymentNodeSelector implementations : one in production and the other in test environment.

            The one used in test will be able to manage all cases thanks to a little hack

             

            I just have to manage two jboss-ejb-client.xml files.
