Why WebServiceServlet is not able to load servlets in WLS 8.1?
Hello,
I am implementing the WebService using JAX-RPC model in Weblogic 8.1 SP4. I am facing the problem in load WebServiceServlet, if my WebService extends ServletEndpointSupport class of Spring API.
The code attached here,
Java WebService class:
JaxRpcEBusinessService.java:
public class JaxRpcEBusinessService
extends ServletEndpointSupport
implements EBusinessFacade {
/** the WebMDService instance */
private EBusinessFacade eBusinessFacade = null;
/**
* This is a default constructor
*/
public JaxRpcEBusinessService() {
}
protected void onInit() {
this.eBusinessFacade = (EBusinessFacade) getWebApplicationContext().
getBean("eBusinessFacade");
}
// business methods
}
Configuration files:
web.xml
<?xml version="1.0" encoding="UTF-8"?>
