Method setKeepAlive(boolean) not found

[Signit]

I am receiving the following error when I try and compile a class I am working on.

$ javac -classpath /usr/local/coldfusionmx/bea/user_projects/srn/applications/cfusion/WEB-INF/lib/cfx.jar CFX_JSocket.java
CFX_JSocket.java:59: Method setKeepAlive(boolean) not found in class java.net.Socket.
            socket.setKeepAlive(toBoolean(request.getAttribute("KEEPALIVE")));
                              ^
1 error

My socket is being initialized this way:

Socket socket = new Socket(request.getAttribute("HOST"), Integer.parseInt(
            request.getAttribute("PORT")));

The offending line is:

        if (request.attributeExists("KEEPALIVE"))
        {
            socket.setKeepAlive(toBoolean(request.getAttribute("KEEPALIVE")));
        }

Any help would be greatly appreciated.

Which SDK version are you using ?

The setKeepAlive method was introduced in JDK1.3

Type java -version at the command line to see what version you have. (If you don't have the java utility pathed, then make sure you're in the bin folder of your java installation when you do this).

Sorry about that, I wasn't sure which to choose and chose this one.

And am using notepad to put this together compiling at the command line.

I am using JVM 1.08.

Whoops, realize I didn't put my JDK on the above post: 1.42.04.

Is that the same version you see when you type

java -version

That's actually what my middleware group told me we were using.

Well, can you check using the above command please. That will confirm the version.

Also, try to compile this class :

import java.net.Socket;
public class TestSocket {
	public static void main(String args[]) throws Exception {
		Socket s = new Socket("localhost", 1099);
		s.setKeepAlive(true);
	}
}

If it does not compile, then you have a SDK lower than version 1.3 - which will not have the setKeepAlive() method.
