Publish SOA Composite application as EJB to be invoked from Java applications using EJB Binding

With the recent (April 2010) SOA Suite 11g R1 Patch Set 2 (11.1.1.3.0), several new capabilities have been added to the SOA Suite. One these is the EJB Binding. Or rather, an enhanced version of this binding. In previous releases, this binding was available to provide interaction with SDO enabled EJBs – based on a WSDL interface and XML messages. The PS2 release added full Java support to the EJB binding. This means that we do not have to concern ourselves with WSDL and XSD that maps to the Java interface we want to invoke or expose, nor with sending a XML based payload when we invoke the composite service. All we need is the Java interface that describes either the EJB that we want to invoke (for an EJB Binding Reference) or that we want to expose (for an EJB Binding Service).

Steps:

1. Create Composite like always

2. Create a Java Interface (and possibly Java domain classes or bean types describing the structure of the input and ouput of the methods on the EJB (that should correspond with the operations available in the Composite application)

package nl.amis.utilities; public interface FilterAndTranslate { public String translate(String input); }

Publishing Java based WebServices using JAX-WS in JDeveloper 11g

Recently I have been doing quite some work with WebServices – calling them and implementing them, from and in both PL/SQL and Java. And in conjunction with BPEL and ESB. Today, I did some quick tests using JDeveloper 11g (TP4) and more specifically JAX-WS. It turns out to be very simple to publish (and test) a Java based WebService – a matter of minutes.

This article will very briefly demonstrate how to get a WebService up and running, based on a simple Java Class. (more…)
