    copied!<p>I have an array that I have created from a database ResultSet. I am trying to Serialize it so that I can send it over a socket stream. At the moment I am getting an error telling me that the array is not Serializable. The code I have is down below, the first part is the class to create an object for the array:</p> <pre><code>class ProteinData { private int ProteinKey; public ProteinData(Integer ProteinKey) { this.ProteinKey = ProteinKey; } public Integer getProteinKey() { return this.ProteinKey; } public void setProteinKey(Integer ProteinKey) { this.ProteinKey = ProteinKey; } } </code></pre> <p>The code to populate the array:</p> <pre><code>public List&lt;ProteinData&gt; readJavaObject(String query, Connection con) throws Exception { PreparedStatement stmt = con.prepareStatement(query); query_results = stmt.executeQuery(); while (query_results.next()) { ProteinData pro = new ProteinData(); pro.setProteinKey(query_results.getInt("ProteinKey")); tableData.add(pro); } query_results.close(); stmt.close(); return tableData; } </code></pre> <p>And the code to call this is:</p> <pre><code>List dataList = (List) this.readJavaObject(query, con); ObjectOutputStream output_stream = new ObjectOutputStream(socket.getOutputStream()); output_stream.writeObject(dataList); </code></pre> <p>And the code recieving this is:</p> <pre><code>List dataList = (List) input_stream.readObject(); </code></pre> <p>Can someone help me serailize this array. All I can find in forums is simple arrays(EG. int[]).</p> <p>I tried to add the serializable to the class and the UID number but got <code>java.lang.ClassNotFoundException: socketserver.ProteinData</code> error message. Does anyone now why?</p> <p>Thanks for any help.</p>
