Hello,
Can JBossWS return a Java object(Java Bean) ? When I try to return a bean, it
just raised the following exception. But those primitive types and String are
no problem at all. The following are my codes:
| import java.util.Hashtable;
|
| import javax.naming.Context;
| import javax.naming.InitialContext;
| import javax.naming.NamingException;
| import javax.xml.rpc.Service;
|
| import eric.ws.reales.CategoryInterface;
| import eric.ws.reales.ProductCategory;
|
|
| /**
| * Client.java
| *
| * @author Chao Hoi Ka, Eric
| *
| */
| public class Client {
| private static CategoryInterface port;
|
| /**
| * @param args
| */
| public static void main(String[] args) {
| try {
| InitialContext iniCtx = getInitialContext();
| Service service = (Service) iniCtx
|
.lookup("java:comp/env/service/CategoryService");
| port = (CategoryInterface)
service.getPort(CategoryInterface.class);
|
| port.addCategory(1, "testing", "tesing again");
| port.addCategory(1, "testingx", "tesing againx");
|
| System.out.println("<<<<"+port.echo("welcome"));
|
|
| ProductCategory cat = port.findById(1);
| System.out.println(">>>>" + cat.getName());
|
| } catch (Exception e) {
| e.printStackTrace();
| }
|
| }
|
| protected static InitialContext getInitialContext(String clientName)
| throws NamingException {
| InitialContext iniCtx = new InitialContext();
| Hashtable env = iniCtx.getEnvironment();
| env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming.client");
| env.put("j2ee.clientName", clientName);
| return new InitialContext(env);
| }
|
| /**
| * Get the client's env context
| */
| protected static InitialContext getInitialContext() throws
NamingException {
| return getInitialContext("jbossws-client");
| }
|
| }
|
|
|
| ....
|
| @WebMethod
| public ProductCategory findById(long id) {
| Object obj = em.find(ProductCategory.class, id);
|
| if (obj != null) {
| return (ProductCategory)obj;
| } else {
| return null;
| }
| }
|
| ...
