handling excpetion errors in web applications

I got this problem: sometimes when I run my web application an error window appears saying for example: "Error opening URL "http://api.google.com/search/beta2" ". When it happens, my application needs to be closed down and restarted again, which is very annoying. Is there any types of exception/error handling? I have in the application code a function named onGoogleSearch which handles the loading process, so I guess the error handling code should be inserted in here...
thanks in advance for the help
