Class Cast Exception using classLoader.getResourcerAsStream

[Hari Gundappa]

Hi,

I am trying to load a properties file from the class path on WAS 6.1.
I get a classcast exception : com.ibm.ws.classloader.Handler$ZipEntryInputStream is not compatible with java.io.InputStream

Here's how my code looks

ClassLoader loader = Thread.currentThread().getContextClassLoader();
ByteArrayInputStream bin = (ByteArrayInputStream)loader .getResourceAsStream(filename);

OR 

InputStream bin = (InputStream)loader .getResourceAsStream(filename);

Both the above fail.

Please advise if I am missing something.

Thanks,
Hari
