Strange "Connection failed" problem when running software

Question

I recently purchased a universal remote that you have to hook up to your computer to program. Every time I try to run the software on my Macbook, I get the following error message: "Connection Failed: The server may not exist or it is not operational at this time. Check the server name or IP address and your network connection and try again."
I have scoured the web and cannot find any other Mac users running into this problem. So, I don't believe the software is the problem. (Plus, I first used a version that came from a CD, and then threw that in the trash and tried a version I downloaded off their website.) I spoke to tech support and they couldn't figure out the problem. I know the remote works fine because I was able to program it using my neighbor's PC.
I've run the software both using my wireless network and while plugged directly into my cable modem, but that didn't work. So, I'm guessing that it has something to do with some type of setting I have on my Mac. I don't have a firewall up (I don't think). I don't have any type of special security software running that I'm aware of. Can anyone think of a reason I would get this type of error, in general?

Expanding on that a bit (or possibly summarising), that static Connection is simply not thread safe.In fact since this is a servlet, even if it were an instance variable it still wouldn't be thread-safe.Indeed.
But my brain was shutting down by the end of the post, which I am blaming on the lack of formatting.
For some reason I thought this was being executed from something created in the doGet/Post() method.Yes, agree with you. It looks like a bird nest
Reading the error stack, it looks like he has the DAO in a separate class, not inside the servlet:
at com.aasc.model.AascOracleShipMethodDAO.getShipMethodInfo(AascOracleShipMethodDAO.java:321)
at com.aasc.view.IndexRequestAction.execute(IndexRequestAction.java:267)
at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:484)
And inside that DAO, he has the static Connection and that is the one
*static Connection connection*; // Data base connection object which connects to data base
public static
Connection createConnection() {
try {...
