The one thing that could be said (so far), is to ensure you are using
properly scoped variables. Generally speaking, for servlets, that means
don't use something like the following:
public class myservlet extends HttpServlet {
private String MyBadlyPlacedVariable = null;
public void doGet() { // exceptions and parameters snipped for
brevity
MyBadlyPlacedVariable =
request.getParameter("some_variable_used_later");
// later on in the code, use "MyBadlyPlacedVariable"...
// it probably contains a value you're not expecting!
}
}
You'll for sure experince threading problems, and this is the most
likely cause of any class of problems that's generically described as:
"the data is actualy mixing up".
