  1. i am follow this all the concept but is not work in my netbeans can u give a exact code for netbeans 8.0.2 version. and my project shows this error
    An Error Occurred:

    java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

  2. i’ve been build the project that following same like yours, but when runing the program. i got an error : “/index.xhtml @12,61 value=”#{mhs.nim}”: Target Unreachable, identifier ‘mhs’ resolved to null “. the code “Student ID: “, i replaced and changes like : ” ID: ”

    please resolved this error for me….

    sorry #badEnglish
