Can someone please explain or direct me to a resource where I can understand why using servlets at any point in an application would be better than jsp or even applets?

I haven't looked at .Net at all, so I everything I say is from a Java perspective. You wouldn't want to hard code HTML in a servlet; it's ugly, and difficult to maintain. Servlets are great for non-visual applications where you need HTTP support (request, response, etc). When you mention code separation I think you are talking about separting the "display code", "business logic", and "control logic". There are many tutorials on the web that mention "Model2" development; a derivation of "MVC". Also, their are many frameworks to choose from to assist your development. Regardless, it all boils down to discipline and proper thinking. Think in layers and OO, e.g. how can you separate the "model" (data), from the "view" (display), from the "control" (logic); all comprise the term MVC. Alone, Java Server Pages (JSP) can be misused by incorporating Java code as scriplets; doing everything from database connections to business logic and application flow. A better approach would be to only put HTML in JSPs and use Java tags to display dynamic data. Your data would go in Java classes that follow the bean convention with private fields and public getters and setters. Your business and application logic would go in other classes; packaged appropriately. While you're at it, you might as well look at decoupling further by putting logic in a set of classes, creating handlers that call DAO classes that handle database accesses, etc. There are many ways to slice an application. I recommend looking into the Apache Struts framework; It's well documented and would be a good learning experience. On top of all that, you still have many other areas to apply the same principles: EJBs, RMI, etc. -- Regards, Anzime ============================================================================== TOPIC: Using hobby source code in your job ? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/a60dfe865a7807c4 ============================================================================== == 1 of 3 == Date: Fri, Dec 3 2004 5:14 pm From: Nils O.

Usually, it is sufficient to write something like Copyright 2004 Skybuck Flying somewhere near the top of each source file. Your employer cannot compel you to transfer the copyright for code that you wrote on your own time or code that you wrote for another employer. You can re-write code that you have written before for your new employer but you cannot copy any of the old code. This is probably the best solution as it gives you a chance to fix mistakes that you make in the old code. My experience is that employers have no objection to using third party packages or even freeware if they can get the necessary licenses at a reasonable price. Don't try to *sell* your employer a license as this creates a "conflict of interest". You can distribute your code under an open source license and you should try to convince your employer to allow you to "contribute" to the package which would allow you to maintain your software on company time. == 3 of 3 == Date: Fri, Dec 3 2004 7:04 pm From: Thomas Matthews Skybuck Flying wrote: > Ok, > > Suppose you have programmed a lot of "re-useable" source code. > > Suppose you're considering taking a programming job in the same language as > your hobby programming language. > > The question rises: > > 1.

Yes, especially under trade secrets, patents, copyrights and ownership. Many employers have a standard of "whatever is created at their facilities or using their equipment is theirs." Some may extend the scope to include any software written by their employees. Read and understand the employment contract carefully before using any personal software for your employer. > 2. For example without thinking about it you might loose the rights to your > hobby source code. That is possible. Read the employment contract.

Don't even take a job in the same programming language as your hobby. No. You can have a hobby that uses the same programming language as your profession.

The custom events do nothing more than write to a JTextArea. It is a log of sorts. After much struggling I was able to get a single custom event from a class which extends a JFrame to write to the JTextArea. I now, however want to have more than one message from the JFrame to be written to the based upon what occurs. I am not clear what is the best way to go about this. It seems that maybe the best way is to "look inside" of my custom event which I have named JFrameEvent. It seems like this is what you do when you do a JComponent.getName(). Another thought I had was to do something with AWTEvent.RESERVED_ID_MAX but again I'm not sure. My question is how (and if) I can expand what I have to have the handler class look into the JFrameEvent and figure out which JFrameEvent has occured? I have marked in the jFrame class where I want the next event to occur. Here's a summary of the code I have: public class jFrame extends JFrame{ public jFrame() { h = new Handler(this); setTitle("crap"); setSize(new Dimension(100,100)); setupMenu(); jp1 = new jPanel1(); getContentPane().add(jp1); this.canLoadDriver(); chooser = new JFileChooser(); } public void canLoadDriver(){ try{ ociCONN = new ociConn(); } catch(ClassNotFoundException e){ // this is the first event I got to work! JFrameEvent jFrameEvent = new JFrameEvent(this); Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(jFrameEvent); // in looking at this I noted it returns JFrameEvent[] maybe I have an array of JFrameEvents ?? not sure how to work with it. System.out.println(jFrameEvent.toString() + " " + jFrameEvent.getID()); } } public void processEvent(AWTEvent e){ if(e instanceof JFrameEvent){ listener.myListenerMethod((JFrameEvent) e); }else{ super.processEvent(e); // there are other events which must be handled such as Mouse Windows etc. // Can use System.out.println(e.getClass().getName()); } } public void addMyListener(MyListener listener){ this.listener=listener; } /** named inner class */ private class copyTypeAction implements ActionListener{ public void actionPerformed(ActionEvent event){ if (dialog == null) dialog = new copyType(); // where the dialog is created if(dialog.showDialog(jFrame.this," ")){ // I want to have another event here.!!!!!!!!!!!!!!!!! chooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY); int result = chooser.showOpenDialog(jFrame.this); } } } // end of named inner class copyTypeAction MyListener listener = null; Handler h = null; private jPanel1 jp1; private ociConn ociCONN; private copyType dialog = null; private JFileChooser chooser; } public class Handler implements MyListener, ActionListener{ public Handler(jFrame j){ j.addMyListener(this); this.j = j; } public Handler(JTextField tf){ String s = tf.getName(); if (s.equals("tf1")){ tf1 = tf; } } public Handler(jPanel1 jp1){ this.jp1 = jp1; } public void myListenerMethod(JFrameEvent e) { //System.out.println("in handler"); jp1.setText("here it is"); /** I really want something like: String s = jp1.getName(); if (s.equals("the class not found")){ jp1.setText("class not found"); else if (s.equals("the class not found")){ jp1.setText("my JFrameEvent just before the chooser") } } */ public void actionPerformed(ActionEvent e) { } private static jFrame j; private static jPanel1 jp1; // private static JTextArea jta; private static JTextField tf1; } public class JFrameEvent extends AWTEvent{ /** Creates a new instance of JFrameEvent */ public JFrameEvent(Object source) { super(source, JFRAME_EVENT); // System.out.println("in JFrameEvent"); } public static final int JFRAME_EVENT=AWTEvent.RESERVED_ID_MAX + 5555; } public interface MyListener extends EventListener{ public void myListenerMethod(JFrameEvent e); } public class jPanel1 extends JPanel{ public jPanel1() { h = new Handler(this); taA = new JTextArea(8, 40); taA.setEditable(false); taA.setName("taA"); JScrollPane scrollPane = new JScrollPane(taA); add(scrollPane); // add the JScrollPane NOT the JTextArea as the // JScrollPane incapulates the JTextArea } public void setText(String s){ taA.append(s); } Handler h = null; private JTextField tf1; private JTextArea taA; } Thank you very much Ox ============================================================================== TOPIC: Abstract IMAP server? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/7a083196a546794b ============================================================================== == 1 of 1 == Date: Fri, Dec 3 2004 5:46 pm From: karl wettin Is there such a thing around?

As JDO is a layer on top on JDBC and it has its own query syntax (I don't think it allows SQL) ... I was wondering if something like the effect of DISTINCT is possible? Like if I had a field in my persitance enabled class called customerName, and it 5 instances had values of "A","B","B","C","D" ... i would want it to get all of them but only one of the "B". Is this possible with JDO?
