Hi All,
I want to implement web services in my project which is a j2ee web application
based on JBoss AS 4.0.5.GA and jbossws-1.2.0.GA.
I installed JBoss AS using "jems-installer-1.2.0.GA.jar" on RedHat Linux RHEL4
(using "all" as a profile for the AS). I bought the "JBoss at Work" book but
it's using the sun's jwsdp tool. Since I'm using JBoss I want to leverage the
wstools which comes with jbossws-1.2.0.GA.
I am trying to implement first the JSR-109 JAX-RPC Service Endpoints:
1) Here is my SEI:
| package generic.hello;
|
| import java.rmi.Remote;
| import java.rmi.RemoteException;
|
| public interface Service_SEI_Interface extends Remote
| {
|
| public String hello(String name) throws RemoteException;
|
| public String purchase (String person, String product) throws
RemoteException;
|
| }
|
2)Here is my JSE:
| package generic.hello;
|
| /**
| *
| * @author dragos
| *
| * This class represents the Endpoint Implementation Bean (=our web service
implementation).
| * JAX-RPC service endpoints (JSEs) provide web services from the web tier.
They take the form of a simple
| * Java objects that masquerade as servlets. This case is implemented in
this generic package.
| * In other specs this is reffer to as "Java Service Skeleton".
| */
| public class POJO_EndpointJSE
| {
| //ddd - insert all business methods that we provide and expose as web
services
|
| public String hello(String name)
| {
| System.out.println("Hello There : " + name + "!");
| return "Hello There : " + name + "!";
| }
|
| public String purchase (String person, String product)
| {
| System.out.println("DDD_EndpointJSE purchase: " + person + "," +
product);
| return "ok" + person + product;
| }
| }
|
3) the input configuration file (wstools-config.xml) for the wstools:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <!-- using this config file, wstools can generate the JSR-109 required
number of deployment artifacts, which are:
| ? webservices.xml, the deployment descriptor that identifies a
deployment of a web service endpoint
| ? wsdl, the abstract webservice contract
| ? jaxrpc-mapping.xml, the mapping desriptor that bridges WSDL to java
-->
|
|
| <!-- RPC Style Endpoint -->
| <configuration xmlns="http://www.jboss.org/jbossws-tools";>
| <java-wsdl>
| <!-- ddd The service element defines the interface our web
service provides -->
| <service name="SampleService"
| style="rpc"
|
endpoint="generic.hello.Service_SEI_Interface"/>
| <namespaces target-namespace="http://hello.generic/";
|
type-namespace="http://hello.generic/types"/>
| <mapping file="jaxrpc-mapping.xml"/>
| <webservices servlet-link="HelloWorldWS"/>
| </java-wsdl>
| </configuration>
|
4)I am running WSTools from the command line like this:
/usr/local/jboss-4.0.5.GA/bin/wstools.sh -cp
/home/dragos/SW/myeclipsews/testbenchWS/WebRoot/WEB-INF/classes/generic/hello/Service_SEI_Interface
-config ./wstools-config.xml
5)Here is my web.xml file:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <web-app xmlns="http://java.sun.com/xml/ns/j2ee";
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
| xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
|
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
| version="2.4">
|
| <!-- ddd declare a pseudo-servlet -->
|
| <servlet>
| <servlet-name>HelloWorldWS</servlet-name>
| <servlet-class>generic.hello.POJO_EndpointJSE</servlet-class>
| <load-on-startup>0</load-on-startup>
| </servlet>
|
| <!-- ddd :
| | 1) We declare our web service implementation class as a servlet and
provide a servlet mapping
| | that will respond to the web service invocations
| | 2) The URL pattern in the servlet mapping is the only externally
visible configuration element
| | = URL the web service lives at = will be primarily noticed as the
location of the WSDL file for this service
| -->
|
| <servlet-mapping>
| <servlet-name>HelloWorldWS</servlet-name>
| <!-- url-pattern>/Service_SEI_Interface</url-pattern -->
| <url-pattern>/services/*</url-pattern>
| </servlet-mapping>
|
| </web-app>
|
6) Here is the output from the command line wstools:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <web-app xmlns="http://java.sun.com/xml/ns/j2ee";
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
| xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
|
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd";
| version="2.4">
|
| <!-- ddd declare a pseudo-servlet -->
|
| <servlet>
| <servlet-name>HelloWorldWS</servlet-name>
| <servlet-class>generic.hello.POJO_EndpointJSE</servlet-class>
| <load-on-startup>0</load-on-startup>
| </servlet>
|
| <!-- ddd :
| | 1) We declare our web service implementation class as a servlet and
provide a servlet mapping
| | that will respond to the web service invocations
| | 2) The URL pattern in the servlet mapping is the only externally
visible configuration element
| | = URL the web service lives at = will be primarily noticed as the
location of the WSDL file for this service
| -->
|
| <servlet-mapping>
| <servlet-name>HelloWorldWS</servlet-name>
| <!-- url-pattern>/Service_SEI_Interface</url-pattern -->
| <url-pattern>/services/*</url-pattern>
| </servlet-mapping>
|
| </web-app>
|
7)To me it looks like the parameters passed to anonymous wrote :
handleJavaToWSDLGeneration(Configuration config, String outDir) are not
instantiated properly cause I not see otherways why later I can't load the end
point class. Here is the pertinent code from the ToolsHelper class:
| public void handleJavaToWSDLGeneration(Configuration config, String
outDir) throws IOException

8) Any ideas about the endpoint class loading issue?
Thanks in advance.
