Subject RE: getParameter not comparing to Strings
Date Thu, 18 May 2000 16:58:02 GMT
So I would write?:

if (request.getParameter("someparameter").compareTo(myrequest) == 0) { }

You have to use compareTo to compare 
two strings. == only works on "" for some 
reason.

Subject: getParameter not comparing to Strings


When I use request.getParameter() it returns a string that look exactly like
the string to which I want to compare it.  Alas, the result of the compare
is that they are not the same.  Attached is a small .jsp that shows the
problem.  What am I doing wrong?


***********start getparameter.jsp**************
<%
String myrequest = "fish";
%>

</head>

<body bgcolor=white>

<h1>
  The result of request.getParameter("someparameter") = 
  <%= request.getParameter("someparameter")%>
</h1>
<a href="getparameter.jsp?someparameter=<%= myrequest%>">test</a><br>
<%
if (request.getParameter("someparameter") == myrequest) {
  out.print(request.getParameter("someparameter") + "==" + myrequest +
"<br>");
} else {
  out.print(request.getParameter("someparameter") + "!=" + myrequest +
"<br>");
}
%>
</body>
