Hi All,
I am developing a GUI based Cocoa-Java application.
I need to invoke some functionalities present in a jar file.This particular
jar file is not built using Cocoa framework.
When I tried to execute the application i got the following error -
2004-12-29 23:18:57.068 CocoaClient[2937] Unknown class `MyAppDelegate' in
nib file, using `NSObject' instead.
2004-12-29 23:18:57.128 CocoaClient[2937] Could not connect the action
onConnect: to target of class NSObject.
Following is the source code of the two files that I have used-
/* MyAppDelegate.java */
import com.apple.cocoa.foundation.*;
import com.apple.cocoa.application.*;
public class MyAppDelegate { // This class is a subclass of
java.lang.Object
public void onConnect(Object sender)
{
try
{
Middle midObj = new Middle();
midObj.establishConnection();
}
catch(Exception e)
{
System.out.println(e);
}
}
/*Middle.java*/
import com.apple.cocoa.foundation.*;
import com.apple.cocoa.application.*;
import ipc.hello.ipp.*;
import ipc.hello.ipp.request.*;
import ipc.hello.hook.*;
import ipc.hello.ipp.response.*;
public class Middle implements MessageReceiver
{
public void establishConnection()throws Exception
{
ServerConnection serv=new
ServerConnection("10.91.194.86",3456,null,0,null);
serv.addMessageReceiver(this);
ReqClientConnect con=new ReqClientConnect(0,0, 3, 0, 3,0);
serv.send(con);
}
public synchronized boolean receive(InMessage message)
{
return true;
}
}
But when I don't create the object of Middle class in onConnect(), the
application runs successfully.
Now is it possible to use the classes present in the jar file from this
Cocoa -java based application.
If yes ,how to go about it .
-Regards,
Hemanta.
