Grab the JSP cheat-sheet at http://java.sun.com/products/jsp/ which will
tell you about all the implicit objects you may access in your scriptlet
code in JSP pages. One of these is the "out" object, defined to be a
JspWriter which will have all sorts of operations for writing out text,
not that I would encourage this in JSP scriptlet code. If you need
println and printing of non-String stuff, you should wrap that JspWriter
with a PrintWriter, as in:
<% java.io.PrintWriter pw = new java.io.PrintWriter(out);
pw.println("<HTML>...</HTML>");
%>
On the other hand, if you are writing a servlet, you need to examine the
Servlet API specification, available for download at the same URL
above. In there you will see a discussion of the
HttpServletResponse.getOutputStream() method, which again, can be
wrapped with a PrintWriter for text/html output:
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
response.setContentType("text/html; charset=iso8859-1");
PrintWriter pw = new PrintWriter(response.getOutputStream());
pw.println("<HTML>....</HTML>");
. . .
pw.flush();
}
