My problem is that when I run a very simple JSF application, EL tags do not get rendered.
For example, this code:
<html lang="en" xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>Facelets Hello World</title>
</h:head>
<h:body> #{hello.world} </h:body>
</html>
It appears both #{hello.word}inside the browser and not "Hello World!" how should be returned by my managed bean:
@ManagedBean(name = "hello")
public class Hello {
public String getWorld() {
return "Hello World!";
}
}
I saw this question JSF 2.0 EL tags do not appear in the browser already, but that didn’t help me. And according to what I read, Tomcat 7 claims to provide an API and an implementation of the EL 2.2 standard.
I use the following software / versions:
- Eclipse Indigo 3.7.2 Java EE Version
- Eclipse Plugin: m2e 1.0.2
- Eclipse Plugin: m2e-wtp 0.15.2
- Maven 2
- Tomcat 7 (tried the following versions)
- Tomcat 7.0.10
- Tomcat 7.0.26
- Tomcat 7.0.27
- MyFaces 2.1.6
- Oracle JDK 1.7.0
