    Hallo,

    ich bin Anfänger in JSF und probiere gerade ein Beispiel-Projekt aufzuziehen, aber das funktioniert leider überhaupt nicht.

    Ich benutze JSF 1.2.

    Was kann ich tun ?

    Ich komme nicht weiter ?

    Bekomme immer folgende Exception:
    Code :
    1

    org.apache.jasper.el.JspPropertyNotFoundException: 
/test_jsf.jsp(16,2) '#{Test_jsf_bean.input}' Target Unreachable, identifier 'Test_jsf_bean' resolved to null

    @MadM
    Thx für deine Antwort.
    Ich habe mein Problem gelöst.
    Es lag an meiner falsch konstruierten WAR-Datei.

    @Alle
    Für alle die Anfänger in JSF sind, empfehle ich als Build-Tool vielleicht lieber apache maven.
    Ich nutze apache ant und daher habe ich meine WAR falsch gebaut.
    Meine test.war hat jetzt folgende Struktur:

    Code :
    1
2
3
4
5
6
7
8
9
10
11

    WebContent\
WebContent\img\
WebContent\META-INF\MANIFEST.MF
WebContent\WEB-INF\
WebContent\WEB-INF\classes\
WebContent\WEB-INF\lib\
WebContent\WEB-INF\faces-config.xml
WebContent\WEB-INF\web.xml
WebContent\pages\test.xhtml
WebContent\stylesheets\
WebContent\templates\

    In meiner build.xml habe ich mein war-target folgendermaßen angepasst:

    Code :
    1
2
3
4
5
6

        <metainf dir="C:/develop/workspace/test_jsf/WebContent/WEB-INF/" />
        <lib dir="C:/develop/workspace/test_jsf/WebContent/WEB-INF/lib/" />
        <classes dir="C:/develop/workspace/test_jsf/build/classes" />
 
        <webinf dir="C:/develop/workspace/test_jsf/WebContent/WEB-INF/">
            <include name="*.xml" />
            <exclude name="web.xml" />
        </webinf>
 
        <fileset dir="C:/develop/workspace/test_jsf/WebContent/">
            <include name="**/*.css" />
            <include name="**/*.html" />
            <include name="**/*.xhtml" />
        </fileset>
 
        <!-- Bilder -->
        <zipfileset dir="C:/develop/workspace/test_jsf/WebContent/img/" prefix="img"/>
    </war>
</target>
