Hi brijesh,

What you could do is use camel route in order to transform and split
the incoming xml message.

I would do something like the following, create an abstract class so i
can also easily do some unit testing:

public abstract class AbstractRouteBuilder() extends RouteBuilder {

    protected final String DIRECT_SPLIT = "direct:split";
    protected final String DIRECT_OUT = "direct:out";
    protected final String DIRECT_AGG = "direct:agg";
    protected final String DIRECT_CLIENT = "direct:client";

    private static final DefaultNamespaceContext CONTEXT = new
DefaultNamespaceContext();
	static {
		CONTEXT.add("tag", "http://yourscheme/");
    }


     public void configure() {

      XPathBuilder<?> yourSplitter = "tag/tag:yourtag";
      yourSplitter.setNamespaceContext(CONTEXT);

      //xslt transfo + split
        from(DIRECT_SPLIT)
            .to("xslt:yourxslt.xsl")
            .splitter(yourSplitter)
            .to(DIRECT_OUT);

      //aggregator with xpath expression
       from(DIRECT_AGG)
            .aggregate()
            .xpath("yourxpathexpression", String.class)
            .to(DIRECT_CLIENT);
       }

}

public class JbiRoute() extends AbstractRouteBuilder {

  from("yourendpoint").to(DIRECT_SPLIT);
  from(DIRECT_OUT).to("yourinwebservice");
  from("youroutwebservice").to(DIRECT_AGG);
  from(DIRECT_CLIENT).to("yourserviceclient");

}
