Keep in mind the system properties are ALREADY in a list. Your goal is to locate the collection and use a loop to iterate through the existing properties print them out (using the get) and concatenating a string value, in this case "<br>" to the get value. Hope this helps without doing it for you!!!

Hello, Could anyone help me complete my first jsp tutorial. I must admit, I am very new to JSP, although I have a reasonable understanding of Actionscript, PHP, HTML, CFML and a bit of Objective- C (so jsp seemed like a natural progression). I'm trying to follow a tutorial found at http://www.jsptut.com/ Mixing.jsp So far I have worked through each tut without to many problems, until I hit the exercise at the bottom of the above page. The exercise asks me to "Write a JSP to output all the values returned by System.getProperties with "<BR>" embedded after each property name and value. Do not output the "<BR>" using the "out" variable." I have no problems printing the values returned by the System.getProperties() call, but the exercise seems to ask me to loop through the result, embedding a <br> after each item!?. I take it I must somehow convert the result to an array that I can then loop through, adding the <br> after each cycle!?. I have tried converting the result using; String myArray[] = <%= System.getProperties()%> but to no avail. can anyone tell me if I'm understanding the exercise correctly and if so, maybe point my in the right direction as I'm running out of hair to pull out!!? many thanks in advance. josh. P.S sorry if my terminology isn't 100%. i plead ignorance! =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
