[Kaushik Chakraborty]

Hi,

I am receiving the following every time I am accessing any site built using 
WebSlinger:

javax.servlet.ServletException: Unknown message with code "Premature end of 
file.".
        
org.webslinger.AbstractMappingWebslingerServletContextFactory.getWebslingerServletContext(AbstractMappingWebslingerServletContextFactory.java:111)
        
org.webslinger.servlet.WebslingerServlet.service(WebslingerServlet.java:45)
        javax.servlet.http.HttpServlet.service(HttpServlet.java:688)

Please help

Thanks,
Kaushik
