Servlets download instead of displaying

Hey all,

Running some java 1.3 servlets on Oracle Application Server. Having a problem where a servlet that is displayed correctly in IE doesn't work in Firefox 2.0. What happen is that instead of displaying in the FF browser, it asks the user to either open or save it. Most servlets work fine. Can anyone see why? code below:

[PHP]package ie.boards.servlet;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.ServletOutputStream;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**
* Servlet implementation class for Servlet: Test
*
*/
public class RedirectServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {

public RedirectServlet() {
super();
}

public void destroy() {
super.destroy();
}

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

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

protected void doPut(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doAll(request, response);
}

protected void doAll(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ServletOutputStream out=response.getOutputStream();
try{
out.println("<html>");
out.println("<head>");
out.println("<script language=\"javascript\">");
out.println("function bustOut(){");
out.println("var newWin = window.open(\"http://x.x.x.x/ie.boards.servlet.MainServlet\", \"appwin\", \"menubar=0,scrollbars=1,status=0,height=715,width=1024\")");
out.println("self.close()");
out.println("}");
out.println("window.onLoad = bustOut;");
out.println("</script>");
out.println("</head>");
out.println("<body onLoad=\"bustOut()\">");
out.println("MainServlet has opened in another window.");
out.println("This window can be closed.");
out.println("</body>");
out.println("</html>");
}catch(IOException e){
System.out.println("IOException: "+e.toString());
}
}

public void init() throws ServletException {
super.init();
}
}[/PHP]

Um, is it a MIME type thing?

Meaning?

Hi,

I think you need to set the content type to HTML to get it to display in the browser:-

response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");

out.println("</html>");

We had a problem with stuff being downloaded as cleartext because the MIME type wasn't set on the server.

<edit>
Or what Dublin Dilbert said.

I'm guessing that once IE see's the first <html> tag it assumes HTML, where as FF doesn't...

Yep that did it. Cheers all. Simple case of leaving out setContentType.
