Getting NumberFormatException

Posted in : JSP-Servlet

Hello Sir, I'm using Integer.parseInt(String str) function which returns a NumberFormatException(Unknown source). I also used Integer.parseInt(String str, int radix) but it also throws the exception. I used the same type of code in a simple .java program but when I.m using it in a JSP it continuously throws the exception. below is the code I used. Please help me out of this problem.

CODE: <% String t2=request.getParameter("time"); int t1=Integer.parseInt(t2, 10); String str="";

%> <% if(t1>=0000 && t1<=2400) { int b=obj.timeInsert(t1); //obj is the object from class DBLogic which has a method to insert time in Database table %>

<%=t2%>

<% } else { str="Wrong Time Entered. Please Enter Proper Time."; } %>
