In Eclipse Java EE servlet does not output to console

Question

I have a simple servlet that creates HTML with PrintWriter and writes to console via System.out.prinln() in the same doGet() method.

I see HTML part in Eclipse (Java EE perspective) but there is nothing in the Console View. Where should stdout from a servlet appear in Eclipse?

Code looks like this:

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


    PrintWriter out = response.getWriter();
    out.println("<h2>Hello from Applet<h2>");


    System.out.println("doGet");
}

If it makes any difference here are the versions, Eclipse Juno, Java EE 7, GlassFish 4 server.

You will find the System.out.println outputs in your web container logs i.e in GalssFish logs.

Eclipse prints the sysout in its own console only for standalone applications and not for web applications. The reason is that, web applications are deployed in web containers and are run under those containers. Eclipse just helps that process of deploying the applicaitons but it does not deploy the webapps within it. Hence you will find the logs in the web container i.e glassfish.

Based off the information you provided me, it's too hard to tell. I would check the server.log file in your file explorer. Make sure it's there. Maybe look at the glassfish configuration file for any log settings.
