I agree with your overall point, but IMHO this is a bad example. WinZIP is just a container for a public-domain compression algorithm, one that is freely available from many other sources. It is a classic case of exploiting the ignorance of Windows users. In this case, WinZIP is the problem, not the user trying to avoid paying for it.

There's no simple answer to this kind of question. You need to assess how hard it would be to fix the program and compare that to the amount of damage that a failure would cause. Costs and benefits, benefits and costs. One thing to keep in mind is that methods don't become deprecated out of mere whim. Face it: A deprecated method is an admission that the original design was deficient. If someone draws a deep breath and confesses "I wuz wrong," you must assume that he considers it more important to warn you off than to save face for himself. A concern that prompts us famously egotistical software types into an embarrassing admission is worth paying some heed to. The Javadoc for a deprecated method usually describes the shortcomings of the original design, and what the consequences of using the method might be. It also usually suggests a substitute method, and this should give you an idea of the difficulty of the fix. Consider the Javadoc as you decide to fix or to let be. -- [EMAIL PROTECTED] ========================================================================== TOPIC: Servlet or EJB design question for Online Store http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/2f0ed03f40147d58 ========================================================================== == 1 of 2 == Date: Tues, Aug 24 2004 1:14 pm From: Sudsy <[EMAIL PROTECTED]> mj wrote: <snip> > I am creating an online store for our company.

Also, even if you decide to go with seperate WebApps, there's no reason why the two applications can't share code and classes. Just because they're both using the same classes doesn't mean you're duplicating code. Just have two different build options from a single source tree.

Where it comes into play is if the size of the Container is smaller than the Components it contains. Giving priority to one of the Components by specifying a higher weightx or weighty will alter the visual rendering. In the situation posited by the OP it doesn't seem to make sense to prioritize the display, any more than it makes sense to specify a gridy of 100 when there are only two Components... :-0 Having spent a bunch of time with GridBagLayout and GridBagConstraints, I'm merely suggesting a beneficial approach.

After all, they are just proportions. If weightx is 0 (which it is by default) then the components won't resize at all on that axis (same deal for weighty). If you do set values for one or more components on an axis, all those values are normalized by Swing internally (range 0..1). So you could set them both to .5, 1, or 2534 as long as they're the same. If you're going to add more components later it can be conceptually simpler to keep track of if you just start out using normalized weights to begin with. The Swing tutorial recommends (for this reason) that you use weights, by axis, that add up to 1.0. Just makes it easier for a reader to visualize. ========================================================================== TOPIC: JDOM Document adapter to InputStream http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/fb30cd48de56e4a5 ========================================================================== == 1 of 1 == Date: Tues, Aug 24 2004 2:05 pm From: [EMAIL PROTECTED] (GIMME) > Any ideas? > Write your JDOM object to a String variable with XMLOutputter's outputString method.

A slightly different approach would be to let the non-String properties of your Form bean have a twin that represents the same value as a String. The Form bean can then convert from and to the String representations (you'll have to call the conversion methods yourself though, unless you extend Struts). -- Oscar Kind http://home.hccnet.nl/okind/ Software Developer for contact information, see website PGP Key fingerprint: 91F3 6C72 F465 5E98 C246 61D9 2C32 8E24 097B B4E2 == 2 of 2 == Date: Tues, Aug 24 2004 7:12 pm From: "WJ" <[EMAIL PROTECTED]> Thanks.

Install the Sun JDK, Download Tomcat, Unzip it. You don't need IIS to develop Java apps with Tomcat. Locally you can simply disable IIS if it is running and run Tomcat instead on port 80, or you can let it peacefully co-exist with IIS and work against port 8080 (or any other port for that matter). Tomcat can easily serve static content (HTML, GIFs, PDFs) just like IIS. After you've written and worked with you application, you'll be much more comfortable with Tomcat and can then delve back in to the arcane details necessary to get Tomcat to work behind IIS, but that's only necessary if their current site is using any of the IIS features (notably ASP) beyond a general web server. If not, just run Tomcat straight and skip IIS. Finally, if you're deciding on a development platform solely on its simplicity to install, you really should reconsider your priorities. Developing in Tomcat is trivial to set up, deploying it behind a web server (IIS, Apache) is a bit more complicated, but that comes much later in the process. Or you can look at commercial solutions like JRrun for "double click" install. > Barring that -- how do you suggest writting software and distribute it to > non-programmer clients who have no idea on how to install the runtime, etc? Go to their site and set it up for them? Write up detailed instructions and tack a phone number on the bottom?

For instance, note that the number of spaces before the "*" starts at a maximum value and decreases by one after each print. Also note the number of "*"s increase from one to a maximum value - then decreases by one to one. You're on the right track of using nested loops - you need to increment one value and decrement another value. Its a good exercise in planning your app. Use flowcharts to plan if it makes things clearer for you. Plan first - then write the code. Hope this helps Hal --- Outgoing mail is certified Virus Free.

You can access data from the .JAD which comes with the MIDlet (or the MANIFEST.MF file if no .JAD): use MIDlet.getAppProperty(String). You can access database through the rms package of MIDP. Note that you will access only database that your MIDlet create (or other MIDlet created with the shared flag set to true). You can't access any file from the phone (for ex., in Symbian OS, you can't open a file by URL: "file://C/System/file.ext"). Or at least that's what I have understood from the JVM sandbox. That gives me idea to try tonight :) -- JScoobyCed What about a JScooby snack Shaggy ? ...

Any suggestions? Yeah. Give the specifics. Post example code. -- Paul Lutus http://www.arachnoid.com == 3 of 3 == Date: Tues, Aug 24 2004 9:30 pm From: "Hal Rosser" <[EMAIL PROTECTED]> You need the Sun JDK - not just the JVM to run JGrasp the jdk come with javac - which you need for JGrasp Install the JDK first - then install JGrasp - then JGrasp will find the jdk and set itself up correctly.

The code comp2D.fillRect(0, 0, 400, 400); works. Thank you very much. import java.awt.*; import javax.swing.*; import java.awt.geom.*; public class Line extends JFrame { public Line() { super("Line"); setSize(410, 430); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); LinePanel lp = new LinePanel(); Container content = getContentPane(); content.add(lp); setContentPane(content); setVisible(true); } public static void main(String[] arguments) { Line line = new Line(); } } class LinePanel extends JPanel { public void paintComponent(Graphics comp) { super.paintComponent(comp); Graphics2D comp2D = (Graphics2D) comp; comp2D.setBackground(Color.white); // comp2D.fillRect(0, 0, 400, 400); Line2D.Double l1 = new Line2D.Double(10,200,390,200); Line2D.Double l2 = new Line2D.Double(200,10,200,390); BasicStroke pen = new BasicStroke(5F); comp2D.setColor(Color.blue); comp2D.draw(l1); comp2D.draw(l2); } } == 2 of 2 == Date: Tues, Aug 24 2004 9:03 pm From: Paul Lutus <[EMAIL PROTECTED]> Jenny wrote: > Hi, > > Could you tell me why the code comp2D.setBackground(Color.white); does > not make the color white? The code comp2D.fillRect(0, 0, 400, 400); > works. Your instruction to set the background white is simply a way to assign a color for the next paint command. But the instruction is issued by code *within* the paint command. The subsequent fillRect() call actually paints with the chosen the color. The setBackground command properly belongs in the main program, not in the paintComponent() method. -- Paul Lutus http://www.arachnoid.com ========================================================================== TOPIC: Migrating from WAS 4.x to WAS 5.x http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/70bad38429735902 ========================================================================== == 1 of 1 == Date: Tues, Aug 24 2004 8:37 pm From: Nevermind <[EMAIL PROTECTED]> Hi All, We are planning to upgrade our app server from WAS 4.x to WAS 5.x. We know that WAS 5.x supports J2EE 1.2 and J2EE 1.3 so we do not need to migrate the EJBs to 1.3, right? What would we lose if do not migrate the code to 1.3? What are the other issues that we should we take care of while upgrading from WAS 4.x to WAS 5.X?
