Java developers

Hi,

I'm looking into coding some J2ME mobile/wireless applications and I'm wondering if there are some reference books that people can recommend. I'm an experienced programmer, so I'm not looking for anything too basic. Should I just go with online docs or are there a some decent books I can get?

I've been looking up html and perl and java codes for search boxes. My major concern is that they search the whole dang internet when I only want the box to search my page.
To be really clear about this, I want to make something like a supermarket barcode scanner for my webpage, and I only want to retrieve the data for the fruits and vegetables listed on my webpage.
So, what's the code I need to be using for this?

I'm taking Advanced Java. The assignment I'm battling is to create a ServerSocket and Socket and simulate a change machine.

Following instructions and using the code bits we've been taught and I can find in my Java book, I've designed and created my programs. My Socket program times out when I try to create the connection.

I started off creating the socket and OutputDataStream before the user prompting program ran. When it kept timing out, I thought it might be because I didn't have any data to put into OutputStream at the creation point, so I've changed things around to create/connect the Socket when I've got data to send. moneyInserted is float.
