Hi Martin,
The script tag here is not meant to be a Javascript, I suppose. Actually it
appears after the </html> close tag!
The code I posted was an example from Jason Hunter's Java Servlet
Programming.
Everything works fine except when the variable 'name' is 'null' and supposed
to output DEFAULT_NAME="world".
Here is the whole code once again :
<HTML>
<HEAD><TITLE>Hello1</TITLE>
<BODY>
<H1>
Hello, <%= getName(request) %>
</H1> <br>
</BODY>
</HTML>
<SCRIPT RUNAT="server">
<%! private static final String DEFAULT_NAME = "World"; %>
<%!
private String getName(HttpServletRequest req) {
String name = req.getParameter("name");
if (name==null)
return DEFAULT_NAME;
else
return name;
}
%>
</SCRIPT>
Any further suggestion(s) ?
-Bob
