java - How should i convert the scriptlet to JSTL? -

 <a href='<%=urlprofile%>'><%=objuserdetailsvo.getlogin_ident()%></td>       <%if(objuserdetailsvo.getflgbifnonbif().trim().equals("y")){        nonbifflag="*";        }         %> 

you need set objuserdetailsvo in request/session/page/application context available jsp. (choose scope suitable here),

now

<a href='${urlprofile}'${objuserdetailsvo.login_ident}'/></td>  <c:if test="${objuserdetailsvo.flgbifnonbif=='y'>        <c:set var="nonbifflag" value="*"/> </c:if> 

note:

you need urlprofile & objuserdetailsvo available jsp mentioned above.

update: (on new question)

<c:if test="${empty nonbifupdatemode}">     nonbifupdatemode empty or null. </c:if>
