    copied!<p>I am designing a java server to respond to multiple client requests. So the design basically has a server socket, accepts a client socket, creates a inputObjectStream and a outputObjectStream from the client input/outputStream.</p> <p>I then use writeobject on the client to make a request, readObject on the server to receive the request. Process it, write the object back on the same stream as a response, and on the client side readobject to process the response.</p> <p>Now, if I run the code on a android emulator/device works fine. The same piece of code if I run on a "android junit java test case", i get a exception after it processes all my requests. The exception is on the server side on readObject call.</p> <pre><code>java.io.EOFException at java.io.ObjectInputStream$BlockDataInputStream.peekByte(ObjectInputStream.java:2570) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1314) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:368)` </code></pre> <p>Question Is it a correct design to read/writeObjects on a iostream ?</p> <p><strong>Edited</strong></p> <p>I have the sample project uploaded on 4shared.com (http://www.4shared.com/archive/98gET_pV/Issue15426tar.html) OR (http://www.sendspace.com/file/v04zjp)</p> <p><strong>Test 1 (PASS)</strong></p> <ol> <li>TestServer project, run it as a Java Application</li> <li>TestClient project, run it as a Android Application</li> </ol> <p><strong>Console Output</strong></p> <p>Server Socket Opened /127.0.0.1</p> <p>Client Socket Accepted</p> <p>Input Stream created</p> <p>Output Stream created</p> <p>Read Object created</p> <p><strong>Test 2 (FAIL)</strong></p> <ol> <li>TestServer project, run it as a Java Application</li> <li>TestClient project, run it as a Android Junit Test</li> </ol> <p><strong>Console Output</strong></p> <p>Server Socket Opened /127.0.0.1</p> <p>Client Socket Accepted</p> <pre><code>Error : Unable to open server socket.
