Question

I’m trying to create an “Hello World” JSF application.
I have a bean with one field (String).

@ManagedBean (name = "beanTest")
@SessionScoped
public class BeanTest
{
    private String myString = "myString";
    public String getMyString()
    {
        return myString;
    }
    public void setMyString(String myString)
    {
        this.myString = myString;
    }
}

When I’m trying to display the string value in my JSP page

<h:outputLabel value="#{beanTest.myString}"/>

In the webpage it displayed "#{beanTest.myString}" instead of "myString"

How is this caused and how can I solve it?

Answer 1

That can happen if your web.xml is declared conform Servlet 2.4 or older, or if your /WEB-INF/lib folder is cluttered with servletcontainer specific libraries like el-api.jar, etc of an older version.

Make sure that the web.xml root declaraton conforms at least Servlet 2.5 or preferably the highest Servlet API version supported by your container and that the /WEB-INF/lib folder does not contain any servletcontainer specific libraries.
