Probably a problem with lacking permissions.

 

You could temporarily grant all permissions to all code in the java.policy file of the JVM.

I've a working serlvet accessing and reading from an RSS stream (using RSSlib4J) and an XPage doing an HTTP request and displaying the results (using HTTPClient from apache.org).

 

Please have a look an http://www.assono.de/blog/d6plinks/EC11-Zaehme-den-Tiger
"Folien" means slides. They are in German, but just go for the demos with source code extracts. You can download the demos for the complete code.

 I can confirm, you do need to loosen the permissions for this to work (at your own risk of course) or you can use the extensibility api to create a component and use that. Those have full security granted to do things like that.

 

 

Jeremy,

 

I loosened the permissions but still got the same error.  

 

This is what I did: 

1. Opened the file "java.policy" in the directory "<Lotus Notes Installation>\jvm\lib\security" and added the following lines to it

2. Restarted my Lotus Notes client (I am doing this on my local machine and local database) 

 

Am I missing something? 

Yes, I have a firewall. 

 

This is crazy!! I will have to completely open up my computer to hackers in order for this program to run.

 

Any other way to read XML/RSS files which does not require compromising security on my computer / servers? 

I know this reply is late but I finally found the culprit - Proxy!

 

If you have a proxy set then you can access websites using the java.net.URL (http://download.oracle.com/javase/6/docs/api/java/net/URL.html) class by calling the function openConnection(java.net.Proxy) and define the proxy address & port.

 

Hope this helps someone else !
