URL parsing issue

I'm having a problem with URL parsing. If I construct a URL
with a user name and password, where the user name contains an @ I get a
malformed URL exception. For example, if my parameters are:

user name = bob@usernet.com
password = password
host = ftp.test.com

and I try to construct a URL:

URL connection = new URL("ftp://bob@usernet.com:password@ftp.test.com");

I get a malformed URL exception. Even though I can connect to the host
with any FTP program or web browser using the same URL. Is this a bug in
Java, a feature, or am I doing something wrong?

The @ in the username should be URL encoded. @ is reserved according to
rfc 1738 and thus has to be encoded for use in the username:

"ftp://bob%40usernet.com:passwd@ftp..."

Thanks for the reply. I'm sure that you're right, as that does work in
every browser that I've tried. But I can't make it work with java 1.5.0.

My mistake. I had an error in the line following this. Thanks for your
help, that did work.
