Java Forum / First Aid / May 2004help with Jtext fields on JSP page?
Hi All, Looking to have a JTextField on a JSP page that gets an int from the users. We would then like to use this value as a multiplier later in the JSP page. Any ideas and help would be welcome. regards Jim Ascroft > Hi All, > [quoted text clipped - 6 lines] > > Jim Ascroft You *really* need to learn some basic HTML first. There are no JTextFields on webpages (how could there be, JTextField is for Swing), only input fields. W3schools has some nice tutorials for (X)HTML: http://www.w3schools.com/xhtml/ You need the <input> tag: http://www.w3schools.com/tags/tag_input.asp  SignatureKind regards, Christophe Vanfleteren Hi Christophe and group, I propbably didnt put my questions all that well. They are.... 1.How can I collect an integer on a JSP page from user input? I am looking to vallidate the user input. I thought about vallidating using HTML then passing/casting the input to a Java variable for further manipulation on the page. I cannot use response.encodeUrl for this. 2.I understand that my Java helper classes are compiled into .class files and then used by the JSP page as required. Also the Java code within the <% %> Java tags is recognised and runs . So if the java between the <% %> tags can be compiled and used why can other Java components eg Swing or AWT not be used in the same way? Effectively what I would like to do is replicate what a JTextField with an action listener would do to retrieve user input in a desktop Java application. Any ideas and help would be welcome. regards Jim Ascroft > > Hi All, > > [quoted text clipped - 17 lines] > You need the <input> tag: > http://www.w3schools.com/tags/tag_input.asp > Hi Christophe and group, > [quoted text clipped - 16 lines] > action listener would do to retrieve user input in a desktop Java > application. I apologise for having a laugh at your expense, but these kind of queries have a tendency to amuse me somewhat. Good luck!

Because the code is compiled and run on the server!! The only thing the client sees is HTML or JavaScript and the like, if you choose to render that. Applets are different most browsers recognise those as an object and the classes downloaded for that purpose, but this must be explicit in the HTML as an instruction to the browser so it knows what to do. If you want Swing in a browser you must use an applet and ensure your client has the neccessary JRE to run it. -- Mike W Free MagazinesGet these publications absolutely FREE for up to 12 months.
