Pelle,
We are using applet to servlet communications with great success.
Here's our working code from the servlet, I think setting the
content type to "application/octet-stream" may be the solution.
BufferedInputStream bufferedIn = new
BufferedInputStream(httpRequest.getInputStream());
ObjectInputStream ois = new ObjectInputStream(bufferedIn);
Object object = ois.readObject();
if (object instanceof Message)
{
httpResponse.setContentType("application/octet-stream");
BufferedOutputStream bufferedOut = new
BufferedOutputStream(httpResponse.getOutputStream());
ObjectOutputStream oos = new
ObjectOutputStream(bufferedOut);
Message reply = this.services.getReply((Message)object);
oos.writeObject(reply);
oos.flush();
bufferedOut.close();
}
Hope this helps,
Rob Griffin
