gnu.kawa.servlet
Class CGIServletWrapper

java.lang.Object
  extended by java.io.OutputStream
      extended by javax.servlet.ServletOutputStream
          extended by gnu.kawa.servlet.CGIServletWrapper
All Implemented Interfaces:
java.io.Closeable, java.io.Flushable, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.ServletConfig, javax.servlet.ServletContext, javax.servlet.ServletRequest, javax.servlet.ServletResponse
public class CGIServletWrapper
extends javax.servlet.ServletOutputStream
implements javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.ServletConfig, javax.servlet.ServletContext

Wrapper class to allow a Servlet to be run as a CGI script. Invoked as: java CGI_ARGS... gnu.kawa.servlet.CGIServletWrapper SERVLET where CGI_ARGS... are properties set from CGI environment variables (for example -DPATH_INFO="foo") and SERVLET is the name of the servlet class. The cgi-wrapper program in ../../../bin can used do this.
