[jboss-user] [EJB 3.0] - Help! ClassCastException: $Proxy?? Issue
I have spent a whole week trying to solve a problem without success. Frankly, I don't
know what else to do except to turn for help here.
For development:
JDeveloper
JbossAS
Window 2003 Server
Components:
Entity bean(AddressEntity.java)
Session bean(AddressFacade.java)
Session bean interfaces(AddressFacadeRemote,java, AddressFacadeLocal.java )
JSF page(create.jsp)
JSF backing bean (Create.java)
Deployment:
foopojo.jar contain POJO and persitence.xml
fooejb.jar contains Session bean classes and jboss.xml
odmweb.war contains: jsp files, backing beans, jboss.web, faces-config.xml, web.xml etc.
odmapp.ear contains: foopojo.jar, fooejb.jar, fooweb.war, application,xml and
jboss-app.xml
application.xml contains
<module>
| <web>
| <web-uri>fooweb.war</web-uri>
| <context-root>fooweb</context-root>
| </web>
| </module>
| <module> <ejb>fooejb.jar</ejb> </module>
| <module><ejb>foopojo.jar</ejb> </module>
| </application>
|
The application is deployed as EAR (fooapp.ear) to jboss-4.2.0.CR1
I have in my backing bean (Create.java):
public String addButton_action() {
| try {
|
| //NOTE: addressEntity is property in this class
| addressEntity.setCreatedBy(user.getUserName());
| java.util.Date timestamp = new java.util.Date(System.currentTimeMillis());
| addressEntity.setDateCreated(timestamp);
| addressEntity.setDateLastModified(timestamp);
| addressEntity.setVersion(1);
| addressEntity.setHits(0);
| getAddressFacadeRemote().createEntity(addressEntity);
| info("Address was successfully created.");
| } catch (Exception ex) {
| ex.printStackTrace();
| error(ex.getLocalizedMessage());
| }
| return "address_create";
| }
|
| public AddressFacadeRemote getAddressFacadeRemote() {
| if(this.addressFacadeRemote == null){
| try {
| Context ctx = new InitialContext();
| //NOTE: RemoteJNDIName is "fooapp/AddressFacade/remote" in the session bean
AddressFacade;
| //NOTE: Next is Line# 236 as reported in the exception thrown
| this.addressFacadeRemote = (AddressFacadeRemote)
ctx.lookup(AddressFacade.RemoteJNDIName);
| }
| catch (NamingException e){
| throw new RuntimeException(e);
| }
| }
| return addressFacadeRemote;
| }
|
Create.jsp is an input form
1. I start the page
2. Fill the form
3. Click a button to process the data
4. The system check for error but there is no error to display
5. The system throws the following error:
08:49:33,578 ERROR [STDERR] java.lang.ClassCastException: $Proxy117
| 08:49:33,593 ERROR [STDERR] at
com.xxx.vmo.foo.pojo.address.Create.getAddressFacadeRemote(Create.java:236)
| 08:49:33,593 ERROR [STDERR] at
com.xxx.vmo.foo.pojo.address.Create.addButton_action(Create.java:846)
| 08:49:33,593 ERROR [STDERR] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native
Method)
|
I can't go past this error no matter what I try. I would appreciate, very much, is
anyone would help.
Thanks in advance.
