Problem with static and nonstatic objects in same code?

Hi everyone, I am working on a project and I kept running into an odd problem where my code would compile but when I went to run the code I would get an exception. I finally narrowed my problem down to a small fragment. Here is an example.
class Mut{
static Mut Fido = new Mut();
Mut Sammy = new Mut();
public static void main(String args[]){
This piece of code will compile but when I run it on an WindowsXP machine the JRE tells me there is an exception at line 3. If I change the code to this:
class Mut{
static Mut Fido = new Mut();
static Mut Sammy = new Mut();
public static void main(String args[]){
The code runs fine without any problems. My question is: why can't I create a static object and a nonstatic object in the same class? Is this a certain feature of JAVA I don't understand or is this a blackbox problem with XP? Any help is appreciated. Thanks

Is the exception stack trace what is displayed in the command-line window? If it is here is what is displayed(This is a lot):

I don't know if this is everything because the winow won't let me scroll back up to where I enterd "java Mut"

  • Problems with static and this

    Hello i am implementing a listener and i try to invoke the listener=this as planned. I am having problems because my method is static and it is so because i need to call that method in my main!
    <code>
         public static void add2hash(String url,ComObject com)
              com= new ComObject(urlPool);
              i++;
              cl = Hashtest;// what to do with this?<-- PROBLEM!!!!
              //new ComObject(); this?
              co.addComListener(cl);
              System.out.println("Let's start!\n ComObject Listening to itself: ");
              String host=str2host(url);
              ht.put(host,co);
              //co.checkStatus();
              //return co.getIs();
    </code>

    RE: tschodt
    I'll start with a comment of agreement :)
    You are having problems because you have yet to grasp the concept of OO.An insightful comment, this seems apparent. :)
    BTW, this has nothing to do with native methods, snip
    Well... just a minor point... but it would appear his code is dealing with some Win32 natives, either from JacobGen or J-Integra, since he is using a ComObject object (I could be way off base as I don't see any import statements.) Maybe follow-up questions in this thread could be relating to the API functionality of some of the classes he's using? :)
    RE: original poster
    If you do want to call this directly from main, take note of the name of the class in which this is defined. Then import the package and class into the class containing your main method (if your main isn't in the same package as the class containing add2hash). Then call OtherClass.add2hash(); from main.
    On another note, in order for us to understand your comment indicating a problem with the ComObject assignment, we'd need to know where you got that object -- maybe show us your import statements? :)

  • Problems with Java and Business Objects

    <p>Hello everybody,<br /><br />I&#39;m new in BusinessObjects/Crystal Report.

    Which Business Objects are you referring to.
    MS .NET has a thing called Business Objects but they only work in .NET.

  • Problem with FWSM and L3 interface in same switch

    I have two 6513s with an 802.1q trunk connecting them. Each switch has redundant Sup720s running in Native mode, IOS ver 12.2(18)SXF (they were initially running SXD3). A FWSM (ver 2.3(3), routed mode, single context) is in each switch, setup in failover mode.
    I can not get a PC, in a vlan that has the layer 3 interface defined on the switch with the active FWSM in it, to communicate with devices "behind" the FWSM. If I move the layer 3 configuration for that vlan to the other 6513, everything works fine.
    The MSFCs are on the inside of the firewall, they have a layer 3 interface configured in the same vlan as the FWSM "inside" interface. Several "same security level" interfaces are defined on the FWSM and used to protect server farms. I am using OSPF on the MSFCs and FWSM and the routing table is correct.
    The FWSM builds connections for attempts made by the PC with the layer 3 interface defined on the same switch as the active FWSM just fine, so this is not a FWSM ACL problem.
    A ping of the FWSM "inside" interface from a PC with the layer 3 interface defined on the same switch as the active FWSM fails, even though debug icmp trace on the FWSM shows the request and the response. A packet capture, using the NAM-2, shows only the request packets. I have captured on the common vlan and the FWSM backplane port channel interface.
    Just to add to the confusion, if I capture in the same places, but do the ping from a PC that is in a vlan with the layer 3 interface defined in the 6513 that does not contain the active FWSM, which works fine, I see the request and reply on the common vlan capture, but only the request on the port channel capture.
    This problem has been there from the beginning of this implementation and has not changed with IOS and FWSM software upgrades. I have experienced this with any and all vlans that I tried to define the layer 3 interface for on the switch with the active FWSM. I have MLS turned on.
    If anyone else has experienced this and solved it, or knows what is going on, I would appreciate any insight.
    Thanks.
    Keith

    I will have to get setup to record more data, but I do know the FWSM showed a ping request and a ping reply at the "inside" interface.
    I believe my problem is related to the IOS command "firewall multiple-vlan-interfaces" which I put in place to allow IPX traffic to be brought around the FWSM. The little documentation that there is for this command, states that policy routing may need to be implemented to prevent ip packets from going around the firewall. I do not have any policy routing in place.
    I also do not have any active layer three interfaces defined for any of the vlans assigned to the firewall except the "inside" interface. So my resoning was that I did not need to be concerned about ip packets having a way around the FWSM. My suspicion is that this command and the fact that I have mls on is causing some type of a problem which results in the packet being "lost" when it needs to be going through the MSFC in the switch with the active FWSM to get to the PC. Hopefully that makes some sense.
    Do you have any idea where better documention on using the "firewall multiple-vlan-interfaces" may be, or a better explanation of all that is happening inside the switch when that command is used?
    Thanks.

  • Problem with Import and Base Object

    Hi everyone
    Last week, I downloaded Flash CS5. I am trying different thing and here is the problem that I dont understand
    I wrote a package like that
    package {
        import flash.text.TextField;
        import fl.controls.Button;
        public class ex1 extends Sprite {
            public function ex1() {
               var myButton:Button = new Bu
    tton();
                var label:TextField         = new TextField();
                addChild(label);
    If I try to execute that script, the compiler returns error
    1046: Type was not found or was not a compile-time constant: Button.
    1180: Call to a possibly undefined method Button.
    If I insert in the main stage (with the Componet Editor) a Button in the main stage, and recompile it, no error.
    If I delete the Button in the main stage and recompile again, no error
    But, If I save the projet and reload it again, I've got the same error
    By the way, I dont have any problem with the textField()
    What is wrong with my setup.
    OTHER QUESTION:
    If in the ACTION FRAME (F9), I insert the folowing code:
    import ex1;
    var a:ex1 = new ex1();
    one more time, I've got error from the compiler. Why ?
    We cannot include a package in the ACTION FRAME ?
    Thanks for your help

    There are some things (including $.fileName) that just do not work in jsxbin's.
    I don't thing the exception hook will work either.
    Either use an ini file in a well known location (~/Desktop) or make sure your
    files are put in Presets/Scripts. That location can be determined with this bit
    of code:
    var SCRIPTS_FOLDER =
    new Folder(app.path + '/' +
    localize("$$$/ScriptingSupport/InstalledScripts=Presets/Scripts"));
    -X

  • Problems with interlaced and progressive on the same timeline ?

    Is there any problem with having both interlaced and progressive on the same timetine ? EG will DVD work OK?
    thanks
    Narada

    Hey Narada,
    I've had projects where I used both and DVD worked just fine. The only thing I'm not sure about now, though, is what I had my field dominance set to. I'm pretty sure it was set to the default so either lower or higher. This leads me to ask the old pros around here a second question:
    What happens to progressive video that's placed in a timeline with a field dominance? Is it no longer treated as progressive?
    Anyway, to answer your question my DVDs worked just fine.
    Hope that helps,
    Cameron

  • Problems with Static and non-static stuff

    Right now I am trying to work on a RPG and trying to make it all using classes instead of having a Applet run everything and want to call Methods to make / remove the buttons here is the Method I'm dealing with
        public void placeButtons()
            attackBtn.setBounds(200,700,75,25);
            defendBtn.setBounds(200,725,75,25);
            magicBtn.setBounds(275,700,75,25);
            itemBtn.setBounds(275,725,75,25);
            game.add(attackBtn);   // Here is where I am having the problem (non-static method add(java.awt.Component) cannot be referenced from a static context)
            attackBtn.addActionListener(this);
        }Normally I would be making all my buttons in my main class but I want to know if I can make them in a separate class and load them in my main class so I can shorten my code by a ton.

    Generally speaking: Yes: you are only limited by your ingenuity and knowledge.
    //call from other class
    MyButtonClass mbc = new MyButtonClass();
    MyPanel p = new MyPanel();
    p.add(mbc.getMyMainButton());
    //what everAlthough I would think that it may be better to get your entire Frame back for display or a panel... It just seems like it's going to be awkward to work with unless you're making some kind of button generator or something, but then it's your app and from your description, the code given should illustrate a way of getting to the answer you seek.

  • Problem with clipping and concerned objects (or rather their color)

    Greeting everyone,
    I hope i don't bother you with things that are already known or, in the end, are a product of my own stupidity ;P
    My problem is the following:
    I was working on a neat design for a list. The first version (without clipping) looked like this:
    [http://www.7pics.info/?image=GHApp-Gradient-Mobile-HowItShouldBe_2c5.jpg]
    As you can see on the bottom, the list was on top of all graphical elements.
    And because this looks stupid, i decide to simply clip the list via "clip: Rectangle{...}".
    Well... turns out it's not as easy as i hoped it would be; all of a sudden the list looks like this:
    [http://www.7pics.info/?image=GHApp-GradientProblem-Mobile-1_fb7.jpg]
    From the left to the right you see the following: first picture is what you'd see initially, from the second to the last i scrolled down one entry each (respectively moved the list up 30 pixels).
    Further scrolling down doesn't change the look, it stays like in the last picture.
    Scrolling up again delivers the same image, but in reverse order.
    The clipping seems to change something in the style of the list elements.
    To be more specific, the gradient of a single element is now applied to the whole list.
    here is a Listing
    //the group which contains the list and the clipping
    Group{
         clip: Rectangle {
              x: 0, y: 70
              width: PublicVars.screenWidth, height: 210
              fill: Color.BLACK        //which color i use doesn't change the look
         content:[
              createChoicesList()
    //create a box for each entry and add text from a string sequence "results"
    createChoicesList():Node[]{
          for(result in results){
                           singleField = Group{
                   Rectangle {
                        fill:  LinearGradient {
                             startX : 0.0
                             startY : 0.0
                             endX : 0.250
                             endY : 0.250
                             stops: [
                                  Stop {
                                       color : Color.LIGHTBLUE
                                       offset: 0.0
                                  Stop {
                                       color : PublicVars.coolGradientBlueTransparent
                                       offset: 0.5
    }I have no clue why this happens. I tried to shift some things around, thinking it had to do something with the order of some elements but... it didn't change anything.
    Another thing i noticed afterwards:
    If i run the App as a desktop program, the gradient effect is all messed up. but this time it doesn't matter if I clip the list or not:
    [http://www.7pics.info/?image=GHApp-GradientProblem-Desktop-1_d5e.jpg]
    The gradients are totally misplaced and if I scroll down they move and appear/disappear randomly across the list entries. sometimes the highlighted elements even look like this:
    [http://www.7pics.info/?image=GHApp-GradientProblem-Desktop-2_89f.jpg]
    Any Ideas?
    P.s.:
    Could it be that retrieving the resolution of a mobile device via
    "var screenWidth = java.lang.Integer.parseInt(FX.getProperty("javafx.screen.width"));"
    isn't very accurate?
    If i use the values i get from this method for the desktop application, the screen will be smaller than in the emulated mobile phone
    Edited by: Mr._Moe on 04.09.2009 21:31

    Not sure about your problem, but I can answer your last question: you can now use the [javafx.stage.Screen|http://java.sun.com/javafx/1.2/docs/api/javafx.stage/javafx.stage.Screen.html] class to get screen dimensions.

  • Problem with 'sort and filter' feature of embed codes in Excel Online Web App

    So my question has to do with the Excel Online feature where you can share a spreadsheet and embed it in a website with the option of allowing users to sort and filter the data. (The option is under the "Interaction" heading.)
    One of the options if you look closely is "Let people sort and filter" which is not checked off. In the embed code you can see "AllowInteractivity=False". The problem is that when I check "Let people sort and filter"
    the embed code changes completely - going from:
    <iframe width="700" height="900" frameborder="0" scrolling="no" src="https://onedrive.live.com/embed?cid=dontworryaboutitEDFD383&resid=6BAA9620AEDFD383%21107&authkey=AFj3X8xq2U3IfDE&em=2&wdAllowInteractivity=False&Item='Sheet1'!A1%3AI32"></iframe>
    to:
    <iframe width="700" height="900" frameborder="0" scrolling="no" src="https://onedrive.live.com/embed?cid=dontworryaboutitEDFD383&resid=6BAA9620AEDFD383%21107&authkey=AFj3X8xq2U3IfDE&em=2&Item='Sheet1'!A1%3AI32"></iframe>
    If I manually change 'false' to 'true' that doesn't do the trick so I'm not sure what to try next.
    Any thoughts?

  • Problem with OpenLDAP and JNDI

    I'm having problem working with OpenLDAP and JNDI.
    First I have changed LDAP's slapd.conf file:
    suffix          "dc=antipodes,dc=com"
    rootdn          cn=Manager,dc=antipodes,dc=com
    directory     "C:/Program Files/OpenLDAP/data"
    rootpw          secret
    schemacheck offthan i used code below, to create root context:
    package test;
    import javax.naming.Context;
    import javax.naming.InitialContext;
    import javax.naming.NamingException;
    import javax.naming.NameAlreadyBoundException;
    import javax.naming.directory.*;
    import java.util.*;
    public class MakeRoot {
         final static String ldapServerName = "localhost";
         final static String rootdn = "cn=Manager,dc=antipodes,dc=com";
         final static String rootpass = "secret";
         final static String rootContext = "dc=antipodes,dc=com";
         public static void main( String[] args ) {
                   // set up environment to access the server
                   Properties env = new Properties();
                   env.put( Context.INITIAL_CONTEXT_FACTORY,
                              "com.sun.jndi.ldap.LdapCtxFactory" );
                   env.put( Context.PROVIDER_URL, "ldap://" + ldapServerName + "/" );
                   env.put( Context.SECURITY_PRINCIPAL, rootdn );
                   env.put( Context.SECURITY_CREDENTIALS, rootpass );
                   try {
                             // obtain initial directory context using the environment
                             DirContext ctx = new InitialDirContext( env );
                             // now, create the root context, which is just a subcontext
                             // of this initial directory context.
                             ctx.createSubcontext( rootContext );
                   } catch ( NameAlreadyBoundException nabe ) {
                             System.err.println( rootContext + " has already been bound!" );
                   } catch ( Exception e ) {
                             System.err.println( e );
    }this worked fine, I could see that by using "LDAP Browser/Editor".
    and then I tried to create group with code:
    package test;
    import java.util.Hashtable;
    import javax.naming.*;
    import javax.naming.ldap.*;
    import javax.naming.directory.*;

              String groupName = "CN=Evolution,OU=Research,DC=antipodes,DC=com";
              env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
              //set security credentials, note using simple cleartext authentication

                   ctx.close();
              catch (NamingException e) {
                   System.err.println("Problem creating group: " + e);
    }got the error code: Problem creating group: javax.naming.directory.InvalidAttributeIdentifierException: [LDAP: error code 17 - groupType: attribute type undefined]; remaining name 'CN=Evolution,OU=Research,DC=antipodes,DC=com'
    I tried by creating organizational unit "ou=Research" from "LDAP Browser/Editor", and then running the same code -> same error.

    I haven't done any chages to any schema manually.
    I know I'm missing something crucial but have no idea what. I have tried many other code from tutorials from net, but they are all very similar and throwing the same error I showed above.
    thanks in advance for help.

    I've solved this.
    The problem was that all codes were using classes from Microsoft Active Directory, and they are not supported in OpenLDAP (microsoft.schema in OpenLDAP is just for info). Due to this some fields are not the same in equivalent classes ("user" and "person").
    so partial code for creating user in root would be:
    import java.util.Hashtable;
    import javax.naming.ldap.*;
    import javax.naming.directory.*;
    import javax.naming.*;
    import javax.net.ssl.*;
    import java.io.*;
    public class MakeUser
         public static void main (String[] args)
              Hashtable env = new Hashtable();
              String adminName = "cn=Manager,dc=antipodes,dc=com";
              String adminPassword = "secret";
              String userName = "cn=Albert Einstein,ou=newgroup,dc=antipodes,dc=com";
              env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
              //set security credentials, note using simple cleartext authentication
              env.put(Context.SECURITY_AUTHENTICATION,"simple");
              env.put(Context.SECURITY_PRINCIPAL,adminName);
              env.put(Context.SECURITY_CREDENTIALS,adminPassword);
              //connect to my domain controller
              env.put(Context.PROVIDER_URL, "ldap://127.0.0.1:389");
              try {
                   // Create the initial directory context
                   LdapContext ctx = new InitialLdapContext(env,null);
                   // Create attributes to be associated with the new user
                        Attributes attrs = new BasicAttributes(true);
                                  attrs.put("objectClass","user");
                   attrs.put("cn","Albert Einstein");
                   attrs.put("userPassword","Nale");
                   attrs.put("sn","Einstein");
                   attrs.put("description","Research Scientist");
                   attrs.put("telephoneNumber","999 123 4567");
                   // Create the context

  • Problems with SwingWorker and classes in my new job, ;), can you help me?

    Hi all, ;)
    First of all, sorry about my poor English.
    I have a problem with Swing and Threads, I hope you help me (because I'm in the firsts two weeks in my new job)
    I have two classes:
    Form1: Its a JPanel class with JProgressBar and JLabel inside.
    FormularioApplet: (the main) Its a JPanel class with a form1 inside.
    I have to download a file from a server and show the progress of the download in the JProgressBar. To make it I do this:
    In Form1 I make a Thread that update the progress bar and gets the fole from the server.
    In FormularioApplet (the main) I call to the method getDownloadedFile from Form1 to get the File.
    THE PROBLEM:
    The execution of FormularioApplet finishes before the Thread of Form1 (with download the file) download the file. Then, when I call in FormularioApplet the variable with the file an Exception: Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException is generated.
    First main begins his execution, then call to Form1 (a thread) then continues his execution and when the execution is finished ends the execution os Form1 and his thread.
    How can I do for main class call the function and the Thread download his file after main class assign the file of return method?
    How can I pass information froma class include an a main class. Form1 can't send to main (because main class made a Form1 f1 = new Form1()) any information from his end of the execution. I think if Form1 can say to main class that he finishes is job, then main class can gets the file.
    I put in bold the important lines.
    Note: My level of JAVA, you can see, is not elevated.
    THANKS A LOT

    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • Problem with JFrame and busy/wait Cursor

    Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
    for the duration of some operation (usually just a few seconds).
    I can get it to work in some situations, but not others.
    Timing does seem to be an issue.
    There are thousands of posts on the BugParade, but
    in general Sun indicates this is not a bug. I just need
    a work-around.
    I've written a test program below to demonstrate the problem.
    I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
    I have not tested on Windows yet.
    When you run the following code, three JFrames will be opened,
    each with the same 5 buttons. The first "F1" listens to its own
    buttons, and works fine. The other two (F2 and F3) listen
    to each other's buttons.
    The "BUSY" button simply sets the cursor on its listener
    to the busy cursor. The "DONE" button sets it to the
    default cursor. These work fine.
    The "SLEEP" button sets the cursor, sleeps for 3 seconds,
    and sets it back. This does not work.
    The "INVOKE LATER" button does the same thing,
    except is uses invokeLater to sleep and set the
    cursor back. This also does not work.
    The "DELAY" button sleeps for 3 seconds (giving you
    time to move the mouse into the other (listerner's)
    window, and then it behaves just like the "SLEEP"
    button. This works.
    Any ideas would be appreciated, thanks.

    I've had the same problems with cursors and repaints in a swing application, and I was thinking of if I could use invokeLater, but I never got that far with it.
    I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread.
