I am working on a simple example where I simply displaying a image using servlet:

public class ImageServlet extends HttpServlet {
private static final long serialVersionUID = 1L;

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    response.setContentType("image/gif");  
    ServletOutputStream out = response.getOutputStream();  
    //Optain image icon
    ImageIcon icon = new ImageIcon("inbox/apple.gif");
    Image image = icon.getImage();
    new GifEncoder(image, out, true).encode();

    out.close();
}
}

Error:

type Exception report
message Servlet execution threw an exception
description The server encountered an internal error that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Servlet execution threw an exception org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)

After read some blog about servlet I found the solution

Just put acme.jar and all other jar file inside the WebContent ->WEB-INF ->lib directory and build project I don't know till now why build path jar file not work for in this scenario.
