How to invoke an EJB running on a current JBoss EAP / JDK from a legacy application running on an old JDK

Solution Unverified - Updated -

Issue

  • We have the legacy system which is using Jboss 4.2.2 and client on java 1.5. And we're using jnp protocol for communicating between client and ejb on jboss 4.2.2. Now we're upgrading our application to be able to run on JBoss EAP 7.1. Unfortunately, jnp is no longer available on EAP 7.1, and we cannot upgrade java version on client environment.

  • We tried to use org.wildfly.naming.client.WildFlyInitialContextFactory from a client on JDK 1.5 but both is getting bad version

  • Is there a way to invoke EJB remotely from client which is running on Java 1.5 environment?
