    Java Servlets


    Hi,
    I want to know the type of input tags in my servlet class, that are defined
    in a html page.
    Ex. if my html page has 4 input tags:
    <input type=text name=first>
    <input type=radio>
    <input type=hidden>
    <input type=checkbox>

    Is there a way I can find dynamically the types of this objects in my servlet
    code. Any help will be appreciated.

    Poonam,

    There is no built-in way of telling this. It is not normally relevant to
    the processing servlet what the input type is for each element. However,
    if your input elements are dynamically generated by a servlet then you can
    dynamically generate hidden fields describing the input type:

    //inside the servlet

    if ((boolean.class.equals(field.getClass())) || (Boolean.class.equals(field.getClass())))
    {
    out.print("<input type=\"checkbox\" name=\"field.getName()\"...");
    out.print("<input type=\"hidden\" name=\"field.getName()" + "_type" +
    "\" value="checkbox");
    } else if ...

    Regards,
    Kent
