SSL Socket Stopped Working with Java1.6

SSL Socket Stopped Working with Java1.6

I wrote some code to do FTP over SSL using Sockets. It worked well using the Java 1.4 JVM in my WebSphere 5.1 installation.

We upgraded to WebSphere 7.0, which uses a Java 1.6 JVM and now it doesn't work. It doesn't throw any exceptions, it just connects and doesn't communicate.

Does anyone know why? Here is my code.


BufferedReader _in = null;
PrintWriter _out = null;
SSLSocket _dataSocket = null;
SSLSocket _sslClient = null;
SSLSocketFactory _factory = null;

public void connect(String host, int port) throws IOException {
    Security.setProperty("ssl.SocketFactory.provider", "");
    Security.setProperty("ssl.ServerSocketFactory.provider", "");
    _factory = (SSLSocketFactory)SSLSocketFactory.getDefault();
    _sslClient = (SSLSocket)_factory.createSocket(host, port);
    _out = new PrintWriter(_sslClient.getOutputStream(), true);
    _in = new BufferedReader(new InputStreamReader(_sslClient.getInputStream()));

I also tried it without the IBM JSSE2 socket factory and that just gives a NullPointerException on the createSocket call.
