EOFException at ObjectInputStream

[David Baer]

I get the following EOFException at ObjectInputStream.readObject:

java.io.EOFException
at
java.ibjectInputStream$BlockDataInputStream.peekByte(ObjectInputStream.java:2435)
at
java.ibjectInputStream.skipCustomData(ObjectInputStream.java:1798)
at
java.ibjectInputStream.readNonProxyDesc(ObjectInputStream.java:1519)
at
java.ibjectInputStream.readClassDesc(ObjectInputStream.java:1435)
at
java.ibjectInputStream.readOrdinaryObject(ObjectInputStream.java:1626)
at
java.ibjectInputStream.readObject0(ObjectInputStream.java:1274)
at java.ibjectInputStream.readObject(ObjectInputStream.java:324)


Server Side Code parts:
public int readFromClient(){
Object obj = null;
try {
obj = fromClient.readObject();
(...)


public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException {
ObjectInputStream fromClient = null;
ObjectOutputStream toClient = null;
try {
toClient = new ObjectOutputStream(response.getOutputStream());
fromClient = new ObjectInputStream(request.getInputStream());
(...)


I'm happy to post more code if needed.

can anybody help me with this exception?

thanks!

Does your client flush?

( toServer.flush() )

Does your client flush?

( toServer.flush() )

yes (i think so). this is my client code:

URL url = new URL(host);
httpCon = (HttpURLConnection) url.openConnection();
httpCon.setDoOutput(true);
httpCon.setDoInput(true);
//httpCon.setRequestProperty("Content-Type", "application/octet-stream");
toServer = new ObjectOutputStream(httpCon.getOutputStream());




InputStream in = null;
try {
in = httpCon.getInputStream();
}
catch (Exception e) {
e.printStackTrace();
}
fromServer = new ObjectInputStream(in);
toServer.writeObject(msg);
toServer.flush();

I think I had this same code before and it worked. I'm using tomcat on the
server-side.

thanks for hints
