Error invoking servlet

[Ramakrishna VasiReddy]

Hi,
I'm getting an error in the browser like this.I'm using bluestone
application server 7.2.2(eval).
I cann't figure it out where its happening.

Compiler Error:
XML translator error: The tag library at '/WEB-INF/struts-bean.tld' could
not be opened: The URI '/WEB-INF/struts-bean.tld' is malformed: no protocol:
/WEB-INF/struts-bean.tld

Thanks in advance
