I am comparing the two string in the IF block and both of the strings are not null but a really weird error is being shown. Even though this same code is working with using simply servlets. But when I run this code in JSP it gives the error. I have already checked if the values were null but the output is exactly what was input in the form. My code is this
<%
String sender = (String) request.getAttribute("sender");
System.out.println(request.getParameter("data") + " " + request.getParameter("sender"));
String process = "process";
if (sender.equals(process)) {
String itemName = request.getParameter("data");
%>
<%="No Item with name: " + itemName + " Found"%>
<%
}
%>
This is the error that is being shown.
Some Error: An exception occurred processing [/error.jsp] at line [31] 28: String sender = (String) request.getAttribute("sender"); 29: System.out.println(request.getParameter("data") + " " + request.getParameter("sender")); 30: String process = "process"; 31: if (sender.equals(process)) { 32: 33: String itemName = request.getParameter("data"); 34: %> Stacktrace: org.apache.jasper.JasperException: An exception occurred processing [/error.jsp] at line [31] 28: String sender = (String) request.getAttribute("sender"); 29: System.out.println(request.getParameter("data") + " " + request.getParameter("sender")); 30: String process = "process"; 31: if (sender.equals(process)) { 32: 33: String itemName = request.getParameter("data"); 34: %> Stacktrace: [Ljava.lang.StackTraceElement;@6fb251a5
