If I start my Login Form the Server crashs with the following Stacktrace

I have registered the UserBean in the faces-config.xml

<managed-bean>
        <managed-bean-name>UserBean</managed-bean-name>
        <managed-bean-class>
            UserBean
        </managed-bean-class>
        <managed-bean-scope>request</managed-bean-scope>
        <managed-property>
            <property-name>Username</property-name>
            <property-class>java.lang.String</property-class>
            <value></value>
        </managed-property>
        <managed-property>
            <property-name>Password</property-name>
            <property-class>java.lang.String</property-class>
            <value></value>
        </managed-property>
    </managed-bean></faces-config>


Here is the stacktrace !

Your problem is that your property should be “username” assuming your getter is “getUsername”. These things are very case-sensitive.
