For some reason JSP documents output XML instead of HTML

OK, so I am trying to set up a simple JSF application. I'm using NetBeans 6.8, Glassfishv3 and Maven2. I made a JSP document like so:

<?xml version="1.0" encoding="utf-8"?>
<html xmlns:f="http://java.sun.com/jsf/core"
      xmlns:h="http://java.sun.com/jsf/html">
<f:view>
    <head>
        <title><h:outputText value="#{Welcome.title}"/></title>
    </head>
    <body>
        <h:outputText value="Welcome"/>
    </body>
</f:view>
</html>

Problem is, if I navigate to this page (http://myHost/myApp/faces/welcome.jspx), it is returned as an XML document, but with the ${Welcome.title} value populated:

<?xml version="1.0" encoding="UTF-8"?>
<html><head><title>Gymix - Welcome</title></head><body>Welcome</body></html>

In Internet Explorer this looks like I would have opened an XML document. In Google Chrome the title is printed next to the text Welcome and instead of the title the URL to the page is printed on the tab.

If I change the JSP document to a plain JSP page (taglibs instead of xmlns and so on) it works and I get a proper page returned. Any ideas on what's wrong? Thanks!

Edit: sadly none of the quick fixes fixed this, so I'll look into this more. BTW, my pom.xml has jsf-api and jsf-impl dependencies with the version for both set to 1.2_14

Aside from the fact that you need to set the proper doctype and content type so that the browser knows what to do with the page, you also should get rid of the old fashioned jspx format and use xhtml format to get the most benefit of Java EE 6-shipped JSF 2.0 and Facelets.

The given code should be changed to:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:f="http://java.sun.com/jsf/core"
      xmlns:h="http://java.sun.com/jsf/html">
    <h:head>
        <title>#{welcome.title}</title>
    </h:head>
    <h:body>
        Welcome
    </h:body>
</html>

Note that the doctype is included and that JSF 2.0 / Facelets will automatically take care about the right content type with help of the <h:head> component. Also note the absence of the <f:view> tag, this isn't needed anymore in Facelets.

You probably also need to reconfigure your webapp to make use of the full powers of JSF 2.0 and Facelets. To learn more about JSF 2.0 and Facelets, I strongly recommend to go through the Java EE 6 tutorial part II chapters 4-9.

Good luck.

Update: as per the comment of bobince: I would add an important note; it is true that the XML declaration (the first line) would mess the rendering mode of some webbrowsers (also see the site behind the doctype link here above), but that's certainly not an issue here. Facelets removes the XML declaration during generating the HTML of the page. The XML declaration is simply there because Facelets needs to parse the page using a XML based tool first. We're talking about a component based MVC framework and XML based templating technology, not about a plain vanilla HTML page ;)

You have to tell the browser what you're sending. I'm not exactly sure of how to do it inside a JSP though, so you'll have to figure out yourself or wait until someone more knowledgeable than me tells you.

You have to send the Content-Type HTTP header indicating your file is a text/html; charset=UTF-8.

Content-Type: text/html, charset=UTF-8

I think you need to put in a valid doctype.

This would go below your xml declaration:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
