URGENT!! synchronization in servlets

Question

Hello
I need to synchronize access to a connection in a servlet. If I make the connection static, and put the connection in a synchronized block, will that work? The servlet is not a SingleThread servlet, so more than one request could be coming through at once. Will synchronization work for this case?
Here is a simplified example of what I mean (this is not actual code, just an illustration)...
public class test extends HttpServlet {
private static Connection con;
public doGet(HttpServletRequest req, HttpServletResponse res)
synchronized(con)
//do stuff with connection here
//output stuff
Please help!

Answer 1

That will work.
But a better alternative, in terms of design would be to define synchronized methods on Connection.
e.g.
public class Connection
public synchronized doStuff () { ... }
That way you are localizing the thread safety issues within Connection, and not exposing those issues to the outside world.
In future, if the Connection can support multi-threaded access, you just have to change the Connection, and not all the calling code.
The way you have done it, the onus is on ALL the callers of Connection.
