String is unicode. This may help you in the future:

I had the same question earlier today when looking at some decompiled code. This URL helped me out: http://www.javaspecialists.co.za/archive/Issue062.html

well since this is the beginner forum I'm gonna assume the answer is easy:
instead of doing this:
UUID yourUUID = new UUID();
do this:
UUID yourUUID = new UUID("Some String goes here");

Well w/o any code its kinda hard to say. With that said, have you checked to see that the vector size EVER decreases? Perhaps you're not starting the thread?

Could you post some code snipets or something? Your requests still have me confused.

Well I'm still not sure about a few things but I wrote up some sample code that may help:
//This assumes you're using a JComboBox for the drop down String date = null; switch (yourComboBox.getSelectedIndex()) { case 0: //0 would be January date += "-JAN-"; break; case 1: date += "-FEB-"; break; // // add rest of cases here // case 11: date+= "-DEC-"; break; } //now for the JTextBox they type the year into date += yourTextBox.getText();
This code assumes you're using JTextBox and JComboBox to get the information. I left the date out because I wasn't sure how you were retrieving it.

Could you elaborate a bit? It looks like you just want to convert a few strings to a single string in a certain format. Is that correct?

I agree with that. I think JSP files should have little actual code. I try to stick with JSP files calling servlets and beans only.

To be able to send an object to any type of stream the object must be serialized. Serializing an object pretty much packs it up so that it can be used again elsewhere. One example would be you can save a serialized object that contains settings to a file when your program exits and next time you run your program you could load the object and have the same settings over again.

JSP is used when you have a lot of HTML to output. Doing that w/ servlets would be a real pain using out.write(). There's nothing that JSP can do that servlets can't. You might what to check out this other thread on the topic:
