Hi, As per my last posting in the forum http://www.jboss.com/index.html?module=bb&op=viewtopic&t=110155 , I followed the document as posted in the forum. I refered the following doc http://wiki.jboss.org/wiki/Wiki.jsp?page=ExternalWebserviceConsumption and I looked into the the following few lines | <action name="soapui-client-action" class="org.jboss.soa.esb.actions.soap.SOAPClient"> | <property name="wsdl" value="http://localhost:18080/acme/services/RetailerCallback?wsdl"/> | <property name="operation" value="SendSalesOrderNotification"/> | </action> | When I modeified in the jboss-esb.xml file and I called an external esb having somethin?wlsdl, I found the exception that class not found. When I tried to look into the several jar file that I did not find the class SOAPClient.java. But this java file is present in your source code. You can have a look. Please help me how to call an external web service using ESB. I will send one soap message(ie an xml file) and I will get a different soap response(ie an .xml file).
