Hi,

I just ran into an UnknownHostException when profiling a little piece of
code that does nothing more than

try {
URL url = new URL("http://www.eclipse.org");
url.openStream();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Running the code without profiling would work. However profiling it throws
the exception saying www.eclipse.org is an unknown host.

Eclipse Europa + TPTP Java 1.5 WinXP

Any Ideas ?
Philipp

Philipp,

This seems like an environment configuration problem. If you are behind
a Firewall or a Proxy server, it is likely that the Java environment
used by Eclipse is configured to pass the Proxy/Firewall while the
environment used by the Profiler (actually, the Agent Controller) is not
properly configured.

Here's an example, if you are behind a proxy server, adding the
following command line options to the VM argument will resolve the
problem (replace the mock up values with real ones):

-Dhttp.proxyHost=proxy.mycompany.com -Dhttp.proxyPort=8080

HTH,
Asaf
