There's a couple of things that I would do:
Firstly avoid calling any variable by a name that is already a java class even if you use lower case at the beginning. This can sometimes cause strange bugs in my experience, and it's not good practice anyway. So change the String variable called "date" into "theDate" or such like. Then check this variable's value, because it looks like that's the one that's got a bad value for the Date parser. Do a System.out.println on that variable so it shows up in your log, or if you've got a debugger, take a look at it before it throws the exception.
You're catching the exception but you're not doing anything with it, which is ALWAYS a bad idea.
Put in a System.out.println there and if you put a stacktrace as well it will tell you in your log which line has thrown the exception, which is ninety percent of the battle:
}catch(Exception e){
System.out.println("MyServlet: " + e.toString());
e.printStackTrace(System.out);
