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
