    Hi,
    In main.jsp i wish to display the data from the database( user information stored in user table ). my codein main.jsp is:

    <h2> description about user:</h2>
    <% Statement st = null;
    ResultSet rs = null;

    rs = st.executeQuery("Select description from user ");
    %>
    <option value = "<%=rs.getString("description")%>" >
    </option>
    when i run the above code it shows the error:
    java.lang.NullPointerException
    org.apache.jsp.main_jsp._jspService(main_jsp.java:72)
    like at above red color line
    can anybody have solution for above or any alternative code.
    Thanks and regards
    Haresh

    well you are calling the method on an object (st) reference set to NULL doesnt make any sense to me
    that code is going to throw a NullPointerException.
