  - What Lies Beneath-Feature Article in Better Software MagazineWhat Lies Beneath
    by Ryan English
    
    According to a recent ABC News/Washington Post survey on identity
    theft, 84 percent of Americans polled believe that corporations are not
    doing enough to protect customers' personal data. The Privacy Rights
    Clearinghouse recently published the results of a survey that found 45
    percent of identity theft cases involve hacking. One-third of all
    identity theft cases are a result of Web application security
    vulnerabilities. These vulnerabilities can be costly and result in the
    exposure of large amounts of confidential information. Major public
    companies, including Google, T-Mobile, CVS, and MSN, were exploited in
    2005 through Web application security vulnerabilities. CardSystems lost
    its biggest partner, Visa, when it was announced that information from
    forty million credit cards might have been exposed to hackers.
    
    If many hacking attempts are for the purpose of identity theft, it is
    difficult to understand why so many organizations continue to install
    Web applications on the Internet without first checking for security
    defects and vulnerabilities. If you asked a group of developers and
    testers if they pride themselves on producing robust, defect-free
    applications, all of them would say yes. But if you asked the same
    question about secure code, few would have an answer. Yet security
    vulnerabilities are software defects. If a product has security
    vulnerabilities that will allow a hacker to steal confidential data or
    even shut down the application, then a solid, high-quality application
    has not been produced.

  - Java SDK on Linux (problem)I have a Java SDK (j2sdk1.4.1_02) installed on a Linux system (2.2.14).
    All seemed to be going well until I noticed something a bit strange.
    Running a java app appears to result in the launch of over a dozen
    consecutive processes. Suspecting the possibility of a weird, multi
    threaded app, I wrote a small test program, Hello.java (appended below).
    Same behaviour. Other than setting the CLASSPATH environment variable
    appropriately and unpacking the kit, the system appears to have no other
    java-specific configuration settings that I can find.
    
    Any ideas?
    
    // Hello.java
    package hovnanian.examples.gui;
    
    import javax.swing.*;
    import java.awt.*;
    
    public class Hello extends JFrame {
    public static void main(String[] args) {
    Hello h = new Hello();
    }
    public Hello() {
    super("Hello");
    
    String message = "Hello world!";
    Label lbl = new Label( message );
    this.getContentPane().add(lbl);
    this.pack();
    this.setVisible(true);
    }
    }

  - Problem with Java panelsI want to write application with few tabbed panels each with split
    panel inside. Some of those split panels should share the same panel
    as in code below.
    //----------------//
    JTabbedPane tabbed = new JTabbedPane();
    
    JSplitPane split1 = new JSplitPane();
    JSplitPane split2 = new JSplitPane();
    
    JPanel panel1 = new JPanel()
    JPanel panel2 = new JPanel();
    JPanel panel3 = new JPanel();
    
    split1.setLeftComponent(panel1);
    split1.setRightComponent(panel2);
    
    split2.setLeftComponent(panel2);
    split2.setRightComponent(panel3);
    
    tabbed.addTab("1",split1);
    tabbed.addTab("2",split2);
    //------------------------//
    
    Unfortunately in split1 panel I cannot see panel2 but only panel1. In
    split2 panel it all works fine. Why it doesn't work?

  - Reading Values from a text file.Hi,
    
    I have a problem reading in values from a text file. Basically i have a
    webservice that gets queries from a database, and i wish to read the
    queries in from a text file. I know how to read a text file but what i
    really want to say is:
    
    open file;
    read first line of file;
    use this line as query;
    do query processing;
    then read next line of query;
    .....
    .....
    ....
    etc
    
    what i would like to know is there a way of looping through the lines?
    
    Many thanks

  - ConcurrencyHi,
    
    I have a program with two classes. One class works out a value and
    returns it in the form of an array, the other class adds together all
    of the arrays returned by the first class.
    What I'm trying to do is get the processes running concurrently, so
    while the first process is working out all the values, the second is
    adding them all up.
    I currently have something like this which it working but I'm unsure
    whether it is actually concurrent:
    
    for(int x=1; x<=y; x++)
    {
    getValue P = new getValue();
    int[] temp = P.calculateValue(x);
    
    arrayAddition C = new arrayAddition() ;
    total = C.addArrays(total,temp);
    }
    
    I've also experimented with a buffer but with no luck.
    Any help would be appreciated,
    
    Thanks,

  - Displaying multi-line textHi all,
    I want to display text on the screen, I would normally use a JLabel but I
    want this text to span over about 3 lines. I am trying to use a JTextArea
    but I want the background to be transparent, like the JLabels. I can not
    find anywhere in the API on how to do this. Any help or alternative ideas to
    using JTextArea would be greatly appreciated.
    
    Many thanks

  - Struts html:select question.I want to accomplish....
    
    I have to query a database whic return list of employee records.
    In the front end, i have to show, list of all firstName's in a list
    box style
    (<select multiple> <option>). If user decides to add more employees,
    then
    i have to validate the name(with no special characters) and proceed to
    the
    next screen. There i need to show the newly added name in that screen
    along
    with all other fields empty. So that user can add that fields.
    
    For this, i am doing like this.
    
    When i query database through my Action execute() method, database
    returns a set of employee records. I am capturing all those in my
    NameBean[] and passing it to JSP.Code looks like this..
    
    NameBean[] name = DatabaseReturnsListOfEmployees...
    request.setAttribute("MyNameBean", name);
    
    In my JSP
    <select name="allName" multiple>
    <logic:iterate id="MyNameBean" name="MyNameBean">
    <option> <bean:write name="MyNameBean" property="firstName"/>
    </logic:iterate>
    </select>
    
    This code populates <select> <option> with all the firstName in the
    list box.
    Now my JSP looks like a ListBox.
    
    The question is when i tried to add new firstName in the ListBox, how
    do i take it to the Action class? Since ListBox MyNameBean is
    NameBean[] and the Action's execute() method has ActionForm has form
    value. Not a ActionForm[] value. See below.
    
    public ActionForward execute(ActionMapping mapping,
    ActionForm form,
    HttpServletRequest request,
    HttpServletResponse response)
    
    Thanks in advance

  - Beautify HTMLHi,
    
    I need to beautify HTML files from within my web application. These
    files come from an online editor that writes its output on a single line.
    
    JTidy might be a solution, but there is no documentation and so it's
    very hard to test it on the fly. After all, I don't need a complete
    parser: a simple formatter/beautifier would be great. Does anyone know
    of such a class? Arachnophilia does it, but it's not an API.
    
    Thanks

  - Tele-conference demoI know Microsoft has teleconference software, can
    do tele-presentation, demo
    But I prefer do things simple
    
    I am thinking use java.awt.Robot class do
    the screen catch every second, then write
    to the image into a buffer file pipe
    in web server.
    
    Then in the web page create
    an applet read from that buffer file pipe.
    
    So when I doing demo, I start my program run
    in background, do screen catch, write to web
    server.
    
    User just http to my applet page watch my demo.
    This is similar to xwatchwin in X11 world.
    But X11 world only work in intranet with small
    group of people, require expensive X-terminal.
    Today every PC has a browser, access to internet.
    
    Do you think this is doable?
    Any better idea?
    Or such Java program already existed? (tell me the download link)
    Thanks!

  - BigDecimal Builder and immutability...Our application uses BigDecimal, and BigDecimal is immutable. Immutability
    is certainly a good thing, but it also means that there are a lot more
    memory allocations (and collections). That's ok, we are all happy that
    Strings are immutable, but Java also gives us StringBuilder and
    StringBuffer. Is there anything similar for BigDecimal?
    
    BigDecimal operations are the hotspots in our application and the GC is also
    very busy collecting all the objects. Unfortunately double are not good
    enough for us. Ideally we would like something like C# Decimal: a 128bit
    decimal number (not floating point, but decimal), I have not actually used
    this, but from what I have heard it is what we would need..
    
    I googled the web for a fixed precision decimal class for Java, for an
    immutable version of BigDecimal, etc... I could not find anything. Do you
    know of anything that could help us?
    
    Thanks,

  - SetProperty per oggetti Complessi Salve a tutti,
    
    sto sviluppando un'applicazione web piuttosto complessa in java che utilizza il framework Bluprint della Sun.
    
    In particolare, la mia problematica è legata alla gestione degli oggetti di business nell'interfaccia con l'utilizzo, nelle jsp, dei metodi setProperty e getProperty java.
    
    Gli oggetti che utilizzo sono i seguenti:
    
    ‘public class Anagrafica implements java.io.Serializable {
    
    ...
    
    private Vector indirizzi;
    
    }
    
    ...
    
    public class Indirizzo implements java.io.Serializable {
    
    protected String tipo;
    
    protected String particella;
    
    protected String address;
    
    protected String houseNumber;
    
    protected String zipCode;
    
    ...
    
    }
    
    Ciò che voglio realizzare è la visualizzazione nella jsp dell'interfaccia di tanti ‘frame' quanti sono gli oggetti Indirizzo contenuti nel Vector di Anagrafica. Scrivendo, però, ciò che segue:
    
    <jsp:useBean id="..." class="..." scope="session">
    
    <jsp:setProperty name="indirizzo" property="*"/>,
    
    il metodo setProperty non setta le proprietà complesse dell' oggetto vector indirizzo.
    
    Spero di esser stata chiara.
    
    Attendo un vostro suggerimento...

  - Heap dump file size vs heap sizeHi,
    
    Do you know how heap dump file size is related to heap size itself?
    I've multiple heap dumps created using jmap on Solaris using Sun JVM
    1.5.0_09 and somehow filesize doesn't relate to heap size itself.
    
    Disproportions are quite big actually (even 500MB - 1GB)

  - How to get a static reference to a genericized class?I can explain much more concisely with an example...
    
    class Cow<C> {
    public Cow (Class<C> clazz) {}
    }
    
    class Milk<T> {}
    
    class Moo {}
    
    Now let's say I want to create a Cow< Milk<Moo> >. What do I pass to
    the Cow constructor?
    
    new Cow<Milk<Moo>>(Milk.class);
    
    This results in the error "The constructor Cow<Milk<Moo>>(Class<Milk>)
    is undefined". This is because the constructor is actually
    "Cow<Milk<Moo>>(Class<Milk<Moo>>)". How can I get a reference to
    Class<Milk<Moo>> without having an instance of a Milk<Moo>?
    
    new Cow<Milk<Moo>>((Class<Milk<Moo>>)Milk.class);
    
    This is better but results in the warning "Type safety: The cast from
    Class<Milk> to Class<Milk<Moo>> will not check conformance of type
    arguments at runtime". Damnit compiler, I know better than you! ;)
    Is there a better solution?

java-programmer, Library for distributed systems I'm looking for a good Java library for doing a distributed app. The
requirements:

* A master machine must be able to dispatch asynchronous messages to slave
machines
* When messages come back, the library must notify the app on the master
machine
* There should be a timeout on the messages
* If the master gets no response from a slave, it should mark the connection
dead and automatically connect to a backup machine. (I suppose it would be
easy to do this in the app).
* Message passing should be fast.
* The API should be reasonably simple.

Does such a library exist?

java-programmer >> Library for distributed systems I think that JMS (Java Messaging Service) is closest to what you desire.
You'll need to find an implementation that suits you. Weblogic has one, as
does IBM among others.

  - SQL Server Stored Procedure Won't returnWe are having a weird problem with our web app running under tomcat
    and sql server 2000. If a certain stored procedure that returns a
    bunch of records is executed then some of our other stored procedures
    will not return until the recordset of the first stored procedure is
    closed. It only seems to cause problems with a couple of stored
    procedures and they look to be using the same tables for their query.
    We are able to open up query analyzer and do a select on the table
    though and it will return the records just fine.
    
    Has anyone ever seen anything like this?

  - getHostName() broken?I'm running 4.9-RELEASE, and have built the jdk1.4.2 port using revision 5
    of the FreeBSD patch kit.
    
    I have a visualization application written in Java by a colleague that I've
    been running. The application shows nodes in a large-scale distributed system,
    and allows clicking on a host to show its Internet hostname.
    
    The code uses getHostName() to do this.
    
    I find that these reverse DNS lookups *all* fail; getHostName() returns a
    String that is a textual representation of the IP address. (There's no
    security manager involved here, BTW. The reference for getHostName() says
    the security manager may check for authorization on getHostName() calls,
    but I've not changed my Java runtime's security policy from the defaults.)
    
    Further poking reveals that *no* outbound DNS queries (traffic destined for
    UDP or TCP port 53) are being generated for these reverse name lookups!
    
    I'm perplexed. Can it really be that InetAddress.getHostName() is broken on
    FreeBSD? Has anyone seen similar behavior, and if so, can you propose a
    workaround, apart from linking in C code to do these reverse name lookups?
    
    Thanks,

  - Strange problem intersecting java.awt.PolygonHi everybody,
    
    I have a strange problem. I am defining a polygon and I try to see if
    it intersects other rectangular shape. Specifically:
    
    java.awt.Polygon pol = new java.awt.Polygon();
    pol.addPoint(1, 0);
    pol.addPoint(1, 1);
    pol.addPoint(0, 1);
    
    if (pol.intersects(0, 0.9, 0, 0.1))
    {
    System.out.println("Intersects here!");
    }
    else
    {
    System.out.println("Do not intersect here!");
    }
    
    And it says: "Do not intersect here!". I'm confused. There should be
    an intersection...
    
    I also tried with:
    
    if (pol.intersects(-0.01, 0.09, 0.01, 0.01))
    {
    System.out.println("Intersects here1!");
    }
    else
    {
    System.out.println("Do not intersect here1!");
    }
    
    And it says again: "Do not intersect here!".
    
    I'm really confused! I hope you can help me!!
    
    About the context of my problem: I have a polygon P and a rectangle R.
    I need to check if R intersects P. If just some points in the boundary
    of P match with points of R, that's also an intersection for my
    purposes (that's why I enlarge R a little bit -0.01 pixels in each
    direction, for example- before calling "intersects"). However, it
    doesn't work as expected.
    
    I hope you can give me some idea about why this isn't working and how
    to solve it!!
    
    Thanks a lot in advance,

  - JList, JComboBox - first letter matching - how to set it up?Hello,
    
    (1)
    I have a sorted JList and I would like to select the item that matches the
    user's keystrokes:
    
    example list {"Cardiff", "Carlisle", "Edinburgh", "Glasgow", "Liverpool",
    "London"}
    
    'L' should select "Liverpool", 'Lo' "London".
    
    I've seen a couple of postings from which I gather that this behaviour is
    already implemented. But I am not sure whether I need to implement a
    KeyListner and buffer the keystrokes and then call getNextMatch() with the
    cached string?
    
    I'd appreciate it if anyone could point me in the right direction.
    
    (2)
    I need a similar feature for JComboBox. Again, does anyone have any ideas
    how to implement this?

  - Middlegen Foreign KeysNot sure if Im doing something stupid, when I add an HSQL foreign key
    to my tables and run MiddleGen, the ejbPostCreate method generates
    wrong and doesnt compile, looks like its a regular set method, but when
    the parameters are explicit it looks like its trying to set an
    object....just a setter, but....seems like a generation issue...anyone
    seen this? Thanks in advance....
    
    public void ejbPostCreate( java.lang.String firstname, java.lang.String
    lastname, java.lang.String email, java.lang.String username,
    java.sql.Timestamp lastonline ) throws javax.ejb.CreateException {
    // Set CMR fields
    setBuddies(buddies);
    }

  - .obj loadingHi All,
    
    I want to load a .obj and its associated .mtl library. I have seen the .obj
    loading demo that comes as part of the java 3d package. Could anybody tell
    me how to load in the .mtl library, or give me link to a demo that does
    this.

  - setResizable on JOptionPane.showConfirmDialog()I create a JDialog using something like
    
    public class Thingies;
    public static void editThingies() {
    ThingyTableModel ttm = new ThingyTableModel();
    JTable table = new JTable(ttm);
    JScrollPane scroller = new JScrollPane(table);
    JOptionPane.showConfirmDialog(
    myApp.frame,
    scroller,
    "Lo! Thingies!",
    JOptionPane.OK_CANCEL_OPTION,
    JOptionPane.PLAIN_MESSAGE,
    null
    );
    }
    }
    
    Since I want it resizable I would like to invoke the JDialog instance's
    setResizable() method. Alas, I can't work out how to get a reference to
    the instance!
    
    I've Googled a bit and browsed various Sun examplets & tutorials but
    still lack clues.
    
    Must I create my JDialog the hard way (i.e. without using the
    JOptionPane.showConfirmDialog())?
