Variables
Hello, I am just curious if a variable is not defined in the JSP page, but is passed through the URL if can be accessed in the page? For exampe:
URL <sample.jsp> <HTML> <% if (variable == "test") { out.println("Variable = test\n"); } %> </HTML>

A variable doesn't appear automatically like it does in php. You can grab a query string variable like this:
<% String myvariable = request.getParameter("variable"); %> Also you can't test for string equality the way you did. if(variable == "test") would test if variable and "test" were the actual same object not just the same characters. you need if(variable.equals("test")) . outprintln() also includes a line return already so you don't need the \n

ok thanks for the help, i appreciate it... but i have another question, does jsp allow you to encrypt objects in the query string... for example in coldfusion i could encrypt the value of variable with something like this : <CFSET variable2 = Encrypt(key, variable)> this just adds a little more peace of mind when dealing with user information.
