Jdk1.3 (also fails with 1.2.2)
JServ 1.2.2
>Description:
[28/06/2000 11:52:32:124 EDT] ECHservlets.Test2: init
[28/06/2000 11:52:32:184 EDT] java.lang.AbstractMethodError
	at org.apache.jserv.JServConnection.processRequest(JServConnection.java:323)
	at org.apache.jserv.JServConnection.run(JServConnection.java:188)
	at java.lang.Thread.run(Thread.java:479)
>How-To-Repeat:
package ECHservlets;

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class Test2 extends HttpServlet
  {
  
  public void doGet( HttpServletRequest req, HttpServletResponse res )
    throws IOException, ServletException
    {
    getServletConfig();
    System.out.println( "getServletConfig" );
    
    getServletConfig().getServletContext();
    System.out.println( "getServletContext" );
    
    getServletConfig().getServletContext().setAttribute( "Test", this );
    System.out.println( "setAttribute" );
    
    Writer w = res.getWriter();
    res.setContentType("text/html");
    w.write("<HTML><HEAD><TITLE>Test</TITLE></HEAD>");
    w.write("<BODY><H1>Test Succeded!</H1></BODY></HTML>");
    w.close();
    }
  }


>Fix:
Tried to rebuild JServ, src distribution is missing "SimpleFileFilter".
Pulled it out of the jar file.  Got many compilation errors -

JServ.java:171: class org.apache.jserv.JServConnection is an abstract class. It
can't be instantiated.
   JServConnection connection = new JServConnection();
