Problem with servlet connection

Question

Hi guys,
Im gettin an nullpointer exception when connect to a servlet. Some "abstract" code:
public void connect()
servletConnection = servletURL.openConnection();
servletConnection.setDoOutput(true);
servletConnection.setUseCaches(false);
servletConnection.setDefaultUseCaches (false);
servletConnection.setDoInput(true);
servletConnection.connect();     
servletInput = new ObjectInputStream(servletConnection.getInputStream());
public codeThatWorks()
while(true)
connect()
usereceivedvalues();
public codeThatDontWorks()
connect()
while(true)
usereceivedvalues();
I dont know why I have to reconnect to the servlet or renew the ObjectInputStream everytime I need to get values from it. Im using a ObjectInputStream to get the values from the servlet.
Some ideas ? Thankss.

I think your problem is in servlet. You can try the servlet without midlet in a IExplorer browser.
ps1=con.prepareStatement("SELECT * FROM userLogin where uID=?");
ps1.setString(1,uID);
ResultSet re=ps1.executeQuery(); It is posible that re will be null.
