"Premature end of file." error from Webslinger Servlet

[Kaushik Chakraborty-2]

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

How did you build a site with webslinger?  What version of ofbiz were
you using?

Look for .cowstate.xml files with a 0-byte size.

[Kaushik Chakraborty-2]

 -  Where to check the .cowstate.xml files? I searched under Var directory
of the site causing problem but could not find any. I restarted OFBiz number
of times but that did not fix the problem (previously for such errors it was
the solution ).
 -  This is a pre-built system with an older version of OFBiz, I think. How
to check the version of OFBiz?

Following is a detailed exception log:

[StandardWrapperValve.java:250:ERROR] Servlet.service() for servlet
