SEVERE: Error filterStart what does Error means

[Senthil Kumar]

Hi,
This is my Filter program,
import javax.servlet.*;
import java.io.*;
public class Filter2 implements Filter
{
private FilterConfig fg;
public void init(FilterConfig fg)
{
this.fg=fg;
System.out.println(" Second Filter initialization");
}

public void doFilter(ServletRequest req,ServletResponse res,FilterChain fc) throws ServletException,IOException
{
System.out.println(" Second Filters do filter");
fc.doFilter(req,res);
}
public void destroy()
{
System.out.println(" Second Filter destroy");
}

}
and it's DD description is
<filter>
<filter-name>Filter2</filter-name>
<filter-class>Filter2</filter-class>
</filter>
<filter-mapping>
<filter-name>Filter2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

when i try to deploy this i'm getting the filterStart error.without this my application is getting deployed.

gee,
i've figured this out to some extent.I've two filters in my application
and in the web.xml i've given the BASIC authentication(this is the gotcha here).when this is there(authentication) with Filter1 my application is deployed without any problem.At the same time when i include the Filter2 error is thrown "filterStart" during deployment.If i remove the security stuff it gets deployed.
Can anyone help me out.....
