Hi everyone,

I just started programming with java and java servlets, and right
now, I
need to implement a servlet that will receive a barcode from a
barcode
reader, and then go through multiple searches, both in the net or in
databases, and then display the results on a webpage.

Right now, I'm a bit lost, because I'm not sure how to make it
work. How
should I implement a program that "waits" for the barcode, and then
sends the barcode to the servlet? Someone told me to use a thread
running in Tomcat, but I have no idea on how to do that.

Can anyone give me some pointers on how to progress?

Thank you!
