Help! ClassCastException: $Proxy?? Issue
ebross Mar 17, 2007 5:58 AMI 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.
