rsslib4j problem javajava.net.MalformedURLException

cousin_borat

I'm am trying to run a client that uses a RSS feed. I'm using the rsslib4j JAR to connect to the RSS feed.

When I try to run the client from the command line I get the following error

Exception in thread "main" java.net.MalformedURLException: no protocol: .\wsdl\hello_world.wsdl

The following is the line of code that throws the error

RSSSRegistry testreg = new RSSSRegistry(new URL(args[0]));

I haven't used java like this before, but 'malformed url' on a line with 'new url(args[0])' suggests junk in args[0] or possibly some required arguments aren't being supplied to the url class (though I'd expect an error message to that effect in that case).

Prior to that statement print the contents of args[0] to the screen to see what's being thrown at the url instantiator. Then track back to see why it's not getting the value it needs. What's in what variable at what point in the process, that's the essence of debugging. Far quicker to examine the data than rethink code.

it looks like the contents of args[0] is '\wsdl\hello_world.wsdl'

Which is indeed an invalid URL as there is no prototol

it should look like
http://
of possibly something like file://c:\dir\ (if the file protocol is supported)

Check out http://www.codefetch.com/search?qy=url&lang=java for some examples of use and http://java.sun.com/j2se/1.3/docs/api/java/net/URL.html the class reference.

Thanks for the replied. I'll have a look at this later on. The goal is to obtain a WSDL file using the RSS protocol.
