    Smile To call java method in jsp

    Hi All,

    I am trying to call a java method in jsp. The main idea is to hide menu based on the user who logs in. Please go through the code and provide me a solution guys.



    The java class flows like this,
    public class UserVerification {

    public static void main(String[] args) {
    UserVerification obj = new UserVerification();
    System.out.print(obj.GetUserVerification("abc"));
    }

    public int GetUserVerification(String empID) {
    int roleId = 0;
    try {

    Class.forName("com.microsoft.sqlserver.jdbc.SQLSer verDriver");

    Connection connection = DriverManager.getConnection("");

    PreparedStatement ps = connection.prepareStatement("");
    ResultSet resultSet = ps.executeQuery();
    while (resultSet.next()) {
    roleId = Integer.parseInt(resultSet.getString(""));
    int RoleID = 0;
    UserMaster um = new UserMaster();
    um.getRoleID();

    while ((RoleID == roleId) && resultSet.next()) {
    UserInfoDisplayController ui = new UserInfoDisplayController();
    List<UserMaster> objUser = ui.GetUserInfoDisplayController(1);
    System.out.print(objUser.size());
    for (UserMaster um1 : objUser) {
    um1.getEmpID();
    um1.getUserName();
    um1.getEmailID();
    um1.getRoleID();
    um1.getSupervisor();
    um1.getTeamID();
    }
    }
    }
    ps.close();
    ps.close();
    connection.close();

    } catch (Exception e) {
    e.printStackTrace();
    }
    return roleId;
    }
    }



    And the javascript and jsp in which i call this are shown below,



    <script type="text/javascript">
    function Validation(RoleID) {
    alert("one");
    var el = document.getElementById(cssmenu);
    alert("two");
    if (RoleID != 2) {
    el.style.visibility == "visible";
    } else {
    el.style.visibility == "hidden";
    }
    alert("three");
    }
    alert("four");
    </script>



    <div id='cssmenu'>
    <ul>
    <%
    if (RoleID != 2) {
    %>
    <li id="menu"><a href="UserMaster.jsp" >User Master</a></li>
    <li id="menu"><a href="SkillMaster.jsp" >Skill Master</a></li>
    <li id="menu"><a href="SkillMapping.jsp" >Skill Mapping</a></li>
    <li id="menu"><a href="Report.jsp" >Reports</a></li>
    <%
    }
    %>
    <li><a href="MySkills.jsp" >My Skills</a></li>
    </ul>
    </div>

    Please go through the code and provide me a solution guys.
    That isn't really how this works. First off, use the highlight tags to preserve formatting when posting code. Secondly. what does this code do? What about your problem are you stuck on?
