SSL java.security.NoSuchAlgorithmException

Question

Java says that in this line, the file ssc.store was not found:

server = ((SSLServerSocketFactory) SSLServerSocketFactory.getDefault()).createServerSocket(port);

(server is a ServerSocket)

I try to use a libary containing this code, but I am not able to open this ServerSocket.

Full Error

What is the problem?

maybe the library is expecting a ssc.store file but it can't find it — nandsito

I'm not very familiar with ssls. But mybe it has smth to do with SSLServerSocketFactory.getDefault()? — Kevin Meyer

the getdefault is ok, but it raises a file not found exception. You are using a library and this library makes the ssl calls, is that right? — nandsito

You need ssc.store file in the working directory where you run your code. The store is here: https://github.com/DeBukkIt/SimpleServerClient/blob/master/ssc.store (or in the specific branch or tag you checked out).

For example, if you're running main method inside IntelliJ, the store file should be in the project root directory. Or, if you pack your application into a jar and run java -jar yourapp.jar, the ssc.store should be in the same directory as the jar file.
