  - Is this syntactically valid Java?Is the following syntactically valid?
    
    public class Foo {
    public static void main(String[] args) {
    for( foo: ; ; ); // Note statement label
    }
    }
    
    javac is rejecting this, but IntelliJ is saying that it is valid. I
    would appreciate a reference to the JLS if possible, so I can file a
    bug report either with Sun or with JetBrains.

  - SPOT smart sensorsFor anyone interested in these but could never get the willpower to
    learn embedded C or somesuch arcane language, these kits from Sun just
    came out:
    
    http://www.sunspotworld.com/products/
    
    Some info:
    http://www.sunspotworld.com/docs/
    
    I had tinkered around with these typrs of objects before, but having
    the thing programmable in Java makes the entire thing easier on my

  - Applet startup error - simple questionGreetings!
    
    I am running into a very strange problem with a very simple code
    
    In my html page I have the following code:
    
    <applet codebase="/" code="InterApplet" width="400" height="150"
    name="InterApplet">
    <param name="OutFrame" value="outFrame" valuetype="object">
    no support for java
    </applet>
    
    When I load the page on Windows 2000 machine running IE6 it works fine
    - applet loads. However, when I try to open this page on a Windows XP
    machine also running IE6 it can't find the applet "load: class
    InterApplet not found". I have my custom built web server so I could
    actually see that the browser did make a request for InterApplet.class
    and web server has served it.
    
    So what in the world is happening?!? This is very frustrating.
    
    I have not done any serious java programming since '97...
    
    Thanks for your time.

  - Java program helpHello everyone, I need your help.. can you check why did i commit an
    error on the n=System.read("enter numer:"); part...? Thanks in
    advance...
    By the way, the program will run as follows:
    the user will input a number, and the program will generate the
    fibonacci series based on the number. if example user input is 4,
    there should be four series of fibonacci...:)
    
    public class fibonacci
    {
    
    public static void main(String args[])
    {
    int prev1 = 1, prev2 = 1, current = 1;int n;
    n = System.read("enter number: ");
    for (int i = 3; i <= n; i++)
    {
    current += prev2;
    prev2 = prev1;
    prev1 = current;
    System.out.println(" " + current);
    }
    
    }
    }

  - Client/Server chat program - wait for connectionHi,
    
    I'm trying to modify a client/server chat program that connects
    immediately, to wait till an IP address is selected from a combo box and
    then connect when a connect button is pressed. The combo box is loaded
    from a file of IP addresses and I select the localhost address of
    127.0.0.1.
    
    I've taken out the app.runClient line from the main class and made it
    the actionPerformed when the connect button is pressed, but the client
    side seems to go dead (won't accept any input) when I do this although
    the connection seems to be working.
    
    Any help appreciated.

  - 2 level RAMAt some it will be economic to create banks of say 10 gigabytes of
    RAM. This ram will be slower than regular RAM, but won't lose its
    value when the power is ostensibly off.
    
    How will this be integrated into Java?
    
    The Windows world will likely treat these as small disk drives. You
    will be able to manually place important files there. Windows will
    fill it with something useless like system recovery snapshots.
    
    However, it could be used more cleverly.
    
    1. as a cache, much like the old Univac 1106 migrated files between
    various speeds of mass storage in order to keep the most commonly used
    ones on the fastest devices. You might even, like the 1106 unify this
    with backup, so all files got backed up to servers on the Internet, or
    spilled there if the disk became full.
    
    2. for large address spaces, to keep infrequently used objects. It
    becomes like your swap file today.
    
    3. something else.

  - storing SecretKey in keystorehi
    i created a keystore as below
    
    public static void makeKeyStore(){
    try{
    KeyStore ks=KeyStore.getInstance(KeyStore.getDefaultType());
    
    ks.load(null,"".toCharArray());
    FileOutputStream ksout=new FileOutputStream("myks.keystore");
    char[] password = new char[] {'m','y','n','a','m','e'};
    ks.store(ksout, password);
    Arrays. fill(password, '\u0000' ) ;
    
    }
    catch(Exception e){
    e.printStackTrace();
    }
    
    }
    
    then i tried to store a generated key using an alias
    
    public static void putEntriestoKS(){
    try{
    KeyStore ks=KeyStore.getInstance(KeyStore.getDefaultType());;
    FileInputStream fin=new FileInputStream("myks.keystore");
    char[] password = new char[] {'m','y','n','a','m','e'};
    ks.load(fin,password);
    FileOutputStream fout=new FileOutputStream("myks.keystore");
    KeyGenerator kg=KeyGenerator.getInstance("AES");
    SecretKey skey=kg.generateKey();
    ks.setKeyEntry("mysecretkey", skey, password,null);
    ks.store(fout,password);
    Arrays.fill(password,'\u0000');
    
    }
    catch(Exception e){
    e.printStackTrace();
    }
    }
    
    when i run this i am getting a java.security.KeyStoreException: Cannot
    store non-PrivateKeys
    How then can i store SecretKey ?Do i have to use another provider?can
    someone explain?
    thanks

  - java.nio problemI had a NIO problem.
    I tried to open a socket channel, and grep a HTML page from HTTP GET.
    I did it success if I open and close socket channel everytime I send a
    request and get the response.
    However, if I keep open the socket channel and send multiple requests,
    I'll get IOException.
    Does anybody know how to solve this problem? Thanks in advance!
    Note: I don't want to fire requests in parallel but one by one
    sample code:
    =============================================================
    private Charset charset = Charset.forName("ISO-8859-1");
    private SocketChannel channel;
    try
    {
    // do connection
    InetSocketAddress socketAddress =
    new InetSocketAddress( "www.mydomain.com", 80);
    channel = SocketChannel.open(socketAddress);
    
    // send request #1
    channel.write(charset.encode("GET /page1.html HTTP/1.0\r\n\r\n") );
    // read response #1
    ByteBuffer buffer = ByteBuffer.allocate(1024);
    while ((channel.read(buffer)) != -1)
    {
    buffer.flip();
    System.out.println(charset.decode(buffer));
    buffer.clear();
    }
    
    // send request #2
    channel.write(charset.encode("GET /page2.html HTTP/1.0\r\n\r\n") );
    // read response #2
    // program threw "java.io.IOException: Read failed" error
    while ((channel.read(buffer)) != -1)
    {
    buffer.flip();
    System.out.println(charset.decode(buffer));
    buffer.clear();
    }
    }
    catch (IOException e)
    {
    e.printStackTrace();
    }
    finally
    {
    if (channel != null)
    {
    try
    {
    channel.close();
    } catch (IOException e) {}
    }
    }

  - Having issues with context listener and netbeansI'm new to netbeans and the whole JSP world in general (i have
    experience in j2me and the j2se). I basically wanted to test out the
    listener functions.
    
    I get no errors with the following code, however, i'm also not able to
    'break' where i want to be able to and I have no output as I would

java-programmer, Writing and running files from a Java/AspectJ application. I'm creating an add-on to windows that will let me create files and run
basic functions such a image editing, both built in and on the hard
drive of a ftp server. If anyone could help me it would be wonderful.
I am planning to use the Eclispe SDK woth the AspectJ plugin. I have
the basic functions set up word editing but I need to know how to run
.exe files on the hard drive.

  - struts: Multipage formHi,
    
    I'm collection data across several pages using one Form per page. The scope of
    each form is set to session. Let's say I have form1, form2 and form3 and the
    corresponding action classes. In the jsp corresponding to form3 I can access
    form1 using form1 as bean name.
    But how can I access form1 from the Action class corresponding to form3?
    
    Hope that was not to confusing.
    
    Thanks in advance,

  - Tomcat4 RMI class loading bermuda triangleHi every body,
    I'm trying to fix this problem for one week and i'm turning crazy
    right now.
    I have this servlet working perfectly, finding every package i put in
    /var/tomcat4/shared/lib except that it doesn't find my RMIServer class
    for casting
    i get a
    [java.lang.ClassNotFoundException] - myRMIServerClass
    org.apache.catalina.loader.StandardClassLoader.loadClass(Unknown
    Source)
    org.apache.catalina.loader.StandardClassLoader.loadClass(Unknown
    Source)
    java.lang.ClassLoader.loadClassInternal(ClassLoader.java:302)
    java.lang.Class.forName0(Native Method)
    java.lang.Class.forName(Class.java:141)
    
    all classes are in the jar with the stub and skeleton (i tried to put
    classes in WEB_INF/classes of my servlet but same problem... so i
    guess this is not the real problem)
    
    I have set in catalina policy file a:
    grant {
    permission java.security.AllPermission;
    };
    to be sure there's no problem of security. i changed the
    init.d/tomcat4 script to add -security to the starting line to be sure
    that it is started the right way
    
    i used to try the same code with tomcat 3 and i changed to tomcat 4
    because of a rmi jni problem reported on mailing lists (i spent so
    much time on tomcat4 that i can't remember what was the previous one)
    but i can't even get that far with tomcat4
    
    my version is a rpm 4.2.1 for Red Hat
    
    does someone understand what's going on

  - Problem with JDBC-ODBC connection to MS Access 2000I am trying to use JDBC-ODBC bridge to connect to a Access 2000
    database on a Windows 2000 machine. I have set up
    the database using the Data Sources utility in Windows 2000. I am
    using the Java(TM) 2 SDK, Standard Edition
    Version 1.4.2_01. The code snippet from an example I found is:
    
    import java.sql.*;
    import javax.swing.JOptionPane;
    
    public class BookDB{
    private static Connection connection;
    private static Statement scrollStatement;
    private static ResultSet books;
    
    public static void connect() throws ClassNotFoundException,
    SQLException {
    
    Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    String url = "jdbc:odbc:MurachBooks";
    String user = "Admin";
    String password = "";
    connection = DriverManager.getConnection(url, user, password);
    }
    
    When I complie I get the following error:
    
    BookDB.java [10:1] cannot resolve symbol
    symbol : method forName (java.lang.String)
    location: class Class
    try {Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
    ^
    1 error
    Errors compiling BookDB.
    
    I have looked at all of the possible sources of information I can
    think of to find an answer to my problem.

  - How often to get a reference to my cached bean?Hi I have an entity bean which caches data. It could sit in the
    container for a very long time.
    
    This entity bean has references to other similary beans that cache.
    Should I get a single reference to the other beans once - on startup or
    should I lookup the bean every time I need it?
    
    MyClassHome refhome = MyHomeHelper.getHome();
    MyCacheClass reference = refhome.find();
    
    The only reason I can think of for looking it up may be if the resource
    (bean) moved to another server due to a crash/failover etc?
    
    thanks

  - Stateless Session Beans and a Stateful Singleton? (Sharing dataI am interested in solving the same problem.
    I currently have a solution involving JMX and WebLogic cluster.
    1-create dynamic Mbean with synchronized methods
    2-register with WL admin server as MBean agent/manager
    3-all managed servers/users in cluster have access to this singleton
    4-as clients log in/out they can invoke addUser/deleteUser methods on
    dynamic mbean. They can also read currentUserCount.
    
    PROBLEM:Single point of failure on admin server.
    Looking for a simpler solution as you described above, OR
    figuring out how to have dynamic MBean replicated in cluster so that each
    managed server uses a local replicated copy--not sure how to achieve this
    yet...

  - Change look of disabled JButtonHello
    
    How can I change the look of a disabled JButton? I have made a boardgame
    with a brown background and brown buttons. I have also put an imageicon on
    the buttons that has a colored image on it. When I disable the buttons, the
    colored image is turned into grey which screws up the look of my game.
    
    Can I change the grey color on a disabled button? Or do I have to keep it
    enabled, and attach another imageicon with different color to show the user
    he can't click the button?
    
    Also, I can sometimes see a blue/gray line around my buttons. I want to get
    rid of it, so I guess it has something to do with setBorder, but I can't
    find it.
    
    Thx,

  - Tomcat classpath and servlets outside of WEB-INFHi,
    Does anybody know if it is possible to execute servlets outside the
    WEB-INF directory? Somebody at work thinks that setting the classpath
    would help. But I have had no luck so far. I'm currently on a
    Win2000 box running Apache, Tomcat 4.1.18, j2sdk 1.4.2. And I found
    out (to my dismay) that symbolic linking doesn't work with Windows. I
    don't even know if symbolic linking would work if it was a linux box.
    People at work say that Tomcat has worked and it was executing
    servlets outside the WEB-INF directory. They are very sure on this
    point. But it broke, and they decided to deleted the entire
    installation (conf file and all). And the person who got it to work
    is no longer here. So I'm at square one. Jserv had been running the
    servlets, but the company wants to move forward. The servlets had
    been mapped to Jserv through the classpath.
    
    Any help or ideas would be greatly appreciated.
