Description Daniel Lipton 2003-06-26 15:11:02 UTC 
Our client's Tomcat installation seems to throw this at random times.  I'm not
what the effect is.  
It's running the web server that comes with Tomcat.

O/S is Windows 2000 Server version 5.0.2195 SP3 Build 2195

Comment 1 Daniel Lipton 2003-06-30 14:05:19 UTC 
By the way, line 25 in BTecServlet is the second line here:

    public void doPost(HttpServletRequest request, HttpServletResponse
response)throws ServletException, IOException{
    	ObjectInputStream in = null;
        ObjectOutputStream out = null;
Comment 2 Daniel Lipton 2003-06-30 14:09:13 UTC 
Excuse me, line 25 is the second line in the following code: (not what I had
just posted)

    public void doPost(HttpServletRequest request, HttpServletResponse
response)throws ServletException, IOException{
    	ObjectInputStream in = new ObjectInputStream(request.getInputStream());
Comment 3 Tim Funk 2003-06-30 14:14:43 UTC 
It "feels" random because the web client is not posting the correct content
length. This usually happens when the web client has aborted the request during
the process of making the post.
