How to send client's public key to server

The client and server are in 2 different machine.  Given the client public key (PublicKey pubC), how do i send pubC to the server and the server received it in the PublicKey format.

Below is an example i found in some some books.  It changes the public key to byte form and send it to the server.  The server received it as bytes.  However i do not know how the get it back to PublicKey form for encryption purposes.

client:
      DataOutputStream out = new DataOutputStream(s.getOutputStream());
      byte[] keyBytes = pubC.getEncode();
      out.writeInt(keyBytes.length);
      out.write(keyBytes);
      out.close();

server:
      DataInputStream in = new DataInputStream(s.getInputStream());
      byte[] keyBytes = new byte[in.readInt()];
      in.readFully(keyBytes);
      out.close();


Below is another method i had tried, but i believed it will only work if the client and the server are in the same machine.

client:
      FileOutputStream ostream = new FileOutputStream("t.tmp");
      ObjectOutputStream out = new ObjectOutputStream(ostream);
      out.writeObject(pubC);
      ostream.close();

server:
      FileInputStream istream = new FileInputStream("t.tmp");
      ObjectInputStream in = new ObjectInputStream(istream);
      PublicKey pubC = (PublicKey)in.readObject();
      istream.close();


Other things to take note are

1. I'm using JDK1.2beta3 with Cryptix-java V3.0.3
2. The public key is generated by Cryptix-java V3.0.3 using RSA algorthim
        BaseRSAKeyPairGenerator kpgC = new BaseRSAKeyPairGenerator();
        kpgC.initialize(64, new SecureRandom());
      KeyPair pairC = kpgC.generateKeyPair();
      pubC = pairC.getPublic();
      privC = pairC.getPrivate();
3. The client and server are in different machines

Is the public key serializable?. In that case, use object serialization and serialize it to stream of bytes and write it to output stream. then on the other end deserialize it.
