[jbossws-dev] [Design of JBoss Web Services] - Inheritance problem
Hello.
I have a problem with class inheritance in web services. I want to make a web service with
one method to add objects of classes (B, C and other in the future) which inheritated from
my basic class (A). My source code:
Server side:
1) TestService.java
@WebService(serviceName = "TestService")
| @Stateless
| @XmlSeeAlso({B.class, C.class})
| public class TestService {
| @EJB
| TestMgmtLocal tl = null;
|
| @WebMethod(operationName = "testAddA")
| public @WebResult(name = "A")
| A testAddA(@WebParam(name = "testA") A testA) {
| return tl.testAddA(testA);
| }
| }
2) TestMgmtLocal.java
@Local
| public interface TestMgmtLocal extends TestMgmtRemote {
|
| }
3) TestMgmtRemote.java
@Remote
| public interface TestMgmtRemote {
| A testAddA(A testA);
| }
4) TestMgmt.java
@Stateless
| public class TestMgmt implements TestMgmtLocal {
| @Resource
| private SessionContext ctx = null;
|
| public A testAddA(A testA) {
| if (testA instanceof A) {
| System.out.println("class A");
| }
|
| if (testA instanceof B) {
| System.out.println("class B");
| }
|
| if (testA instanceof C) {
| System.out.println("class C");
| }
|
| return testA;
| }
| }
5) A.java
public class A implements Serializable {
|
| private static final long serialVersionUID = 110181269433550832L;
|
| private int a = -1;
|
| public int getA() {
| return a;
| }
|
| public void setA(int a) {
| this.a = a;
| }
| }
6) B.java
public class B extends A implements Serializable {
|
| private static final long serialVersionUID = 6921792702940813727L;
|
| private int b = -1;
|
| public int getB() {
| return b;
| }
|
| public void setB(int b) {
| this.b = b;
| }
| }
7) C.java
public class C extends A implements Serializable {
|
| private static final long serialVersionUID = 7823155353151239133L;
|
| private int c = -1;
|
| public int getC() {
| return c;
| }
|
| public void setC(int c) {
| this.c = c;
| }
| }
Client side:
1) TestClient.java
public class TestClient {
|
| public static void main(String[] args) {
| TestServiceProxy proxy = new TestServiceProxy();
| TestService_PortType port = proxy.getTestService_PortType();
| try {
| C c = new C();
| c.setA(2);
| c.setC(3);
| port.testAddA(c);
| } catch(RemoteException e) {
| System.out.println(e);
| }
| }
| }
I found this page:
http://blog.vinodsingh.com/2008/09/anytype-object-over-webservice-and.html
but it doesn't work in my web service. In testAddA method I always get an object of A
class (when I send from client object of B or C class). I've also tried to add
@XmlSeeAlso annotation to A class but it doesn't help. Maybe I did something wrong?
Any ideas? Any other solutions of this problem?
I'm using:
1) JBoss 4.2.3GA (I tired also on JBoss 5.1.GA)
2) Java 1.5 update 15
