Hi, >I had this in the new >URL(http://4526353&[EMAIL PROTECTED]@##$#$$%(()))*(*&&^%^%^) and >it passed. I was expecting to get some error. Should I? No, you shouldn't get an error. It's a valid but nonsensical URL. If you're not clear why this is valid, and are interested, look at RFC 2396. To summarize: everything after the host in an http URL is optional. You have a host name 4526353&*^%$ (to see why the junk after starting with # is not parsed as part of the host name, refer to the above RFC, especially the section on encoding escaped sequences). You can easily confirm java's behavior is consistent with Internet Explorer and other browsers, by comparing the output from System.out.println(new URL(the URL above).getHost()) and what happens when you try to navigate to the above URL in Internet Explore; same processing, same host name (which if it existed would actually be served just fine). In the future, please do a bit more research before making such a bold claim as the java.net.URL implementation being broken with regard to HTTP URLs ;) It had me, for one, worried, and I'm not even a Sun person ;) Yoav This e-mail, including any attachments, is a confidential business communication, and may contain information that is confidential, proprietary and/or privileged.

RE: URL validation
Hi Yoav,
I had this in the new
URL(http://4526353&[EMAIL PROTECTED]@##$#$$%(()))*(*&&^%^%^) and
it passed. I was expecting to get some error. Should I?

Hi,
Can you give examples and/or cases that show java.net.URL doesn't meet

Hi Steffen,
Thanks, new URL(url) doesn't work consistently. I have tried it,
one can throw in an url that doesn't meet RFC 1738 but URL(url) will
not catch it.
Thanks,

try {
new URL( myUrl );
return true;
} catch ( Throwable t ) {
return false;
}
Why not creating it?
Javas young generation garbage collection should dispose this immediatly. So
problem here.

URL validation
Hi all, I don't know if this is the right forum to posse this question, but I will go ahead and give it a try. Here is my problem, I am looking for a way to syntactically valid a given URL without having to actually creating an URL object. Is there a piece of code out there that would enable me to do this based on RFC 1738? Any hints will be appreciated.
