I am currently calling the following line of code:
java.net.URL connection_url = new java.net.URL("http://<ip address>:<port>/path");
and I get the exception above when it executes. Any ideas as to why this is happening?

I'm not getting that same exception with the exact same code.jjnguy– jjnguy2008-09-12 20:21:40 +00:00Commented Sep 12, 2008 at 20:21

What version of Java is causing the exception?John Meagher– John Meagher2008-09-13 00:08:40 +00:00Commented Sep 13, 2008 at 0:08

As a side note, you should be using URI because Java URL class is screwed up. (The equals method I believe)

Not sure why the parent got modded down, but it might be a good idea to use URI in place of URL depending on what you're doing. See: symphonious.net/2007/03/29/javaneturl-or-javaneturi

You probably don't want to use java.net.URI if you're working with URLs as found in the wild (often invalid URIs).
Your code works perfectly fine for me:
public static void main(String[] args) {
try {
java.net.URL connection_url = new java.net.URL("http://:/path");
System.out.println("Instantiated new URL: " + connection_url);
}
catch (MalformedURLException e) {
e.printStackTrace();
}
}
Instantiated new URL: http://:/path
Sure you have the right line of code?

That url string looks like it's invalid. Sure it's not supposed to be 'http://path'? Or are the server & port blank?

Thanks! that worked for me. Had missed adding the protocol before the IP address. I guess Chrome has spoiled me :)
I have also had the same exception, but in my case the URL which I was trying to execute had a space appended. After removing the space it worked fine for me. Check that the URL does not have any trailing spaces in your case.

I had the same error and it got resolved by the below :
The jar files (JFree) which I added few days back got corrupted automatically and was causing this error. I downloaded the same files again from net and it worked fine for me.
