Hi,
I am trying to implement my version
of RMISocketFactory that provides ssl sockets instead of regular sockets.
I extended RMISocketFactory as follows but compiler complains that i can
not extend it's methods!
package bank;
import java.io.*;
import java.rmi.server.*;
import javax.net.*;
import javax.net.ssl.*;
public class CGGAMPSSLSocketFactory extends RMISocketFactory
{
public Socket createSocket(String
host,int port) throws IOException{
SSLSocket socket = (SSLSocket)SSLSocketFactory.getDefault().
createSocket(host,port);
String ciphers[] = socket.getEnabledCipherSuites();
socket.setEnabledCipherSuites(ciphers);
return socket;
}
public ServerSocket createServerSocket(int
port) throws IOException {
SSLServerSocket server = (SSLServerSocket)
SSLServerSocketFactory.getDefault().createServerSocket(port);
String ciphers[] = server.getEnabledCipherSuites();
server.setEnabledCipherSuites(ciphers);
return server;
}
}
Here is the compiler complain,
black:rpatel% javac bank/CGGAMPSSLSocketFactory.java
bank/CGGAMPSSLSocketFactory.java:17: The method
bank.Socket createSocket(java.lang.String, int) declared in class bank.CGGAMPSSLSocketFactory
cannot override the method of the same signature declared in class java.rmi.server.RMISocketFactory.
They must have the same return type.
public Socket createSocket(String
host,int port) throws IOException{
^
bank/CGGAMPSSLSocketFactory.java:25: The method
bank.ServerSocket createServerSocket(int) declared in class bank.CGGAMPSSLSocketFactory
cannot override the method of the same signature declared in class java.rmi.server.RMISocketFactory.
They must have the same return type.
public ServerSocket createServerSocket(int
port) throws IOException {
^
2 errors
black:rpatel%
I am totally lost i have the same function signature as of RMISocketFactory.
Why the compiler does not like it? I would appreciate your quick
response,
Thanks,
-Raj

No, you haven't. You have "bank.Socket createSocket(String, int)" but
it should be "java.net.Socket createSocket(String, int)".
Adding "import java.net.Socket;" or using "java.net.Socket" instead of
the unqualified "Socket" should fix this.

Thank you very much. I had import javax.net.* so i thought it is ok but actually it
requires java.net.Socket as return type and other places it requires javax.net.* So
now it works for that part but now i get following exception. Can you give me some
guideline if possible,
% startserver

I have following in my code to support ssl,
java.security.Security.addProvider(
new com.sun.net.ssl.internal.ssl.Provider());
System.setProperty("java.protocol.handler.pkgs",
"com.sun.net.ssl.internal.www.protocol");
try{
RMISocketFactory.setSocketFactory(new CGGAMPSSLSocketFactory());
}catch (IOException e){
e.printStackTrace();
}
Isn't that enough? What am i missing?

looking for a kernel mailing list
I have a question that would be appropriate for a Linux Kernel list. Does anyone know of a good one? We have written a driver for our proprietary h/w. The driver handles a multitude of interrupts. The bottom half routine calls the corresponding "Interrupt Handler" (static void interruptHandler(void)). I want to be able to dynamically install one of these "Interrupt Handlers". I want to be able to pass the "Interrupt Handler" in from user code (after the driver has already been loaded), maybe via an IOCTL call. Is this possible? Are 2 builds required, one for the "Interrupt Handler" and one for the user code that installs it; Or, can they be built together (#define MODULE). thanks for any help, [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

Re: looking for a kernel mailing list
> I have a question that would be appropriate for a Linux Kernel list. > Does anyone know of a good one? LKML, or the specialized ones (e.g. for USB, networking, etc). The modules bit doesn't make sense to me; are you referring to the kernel driver plus the userspace JNI glue to call it? Or is the userspace code some C code making a JVM call? - Dave > We have written a driver for our proprietary h/w. The driver handles a > multitude of interrupts.
