NetBeans: Calling code from other packages?

Normally, when I would call code from eclipse, I would type something like:
import +<package name>.<class name>+But somehow, this approach doesn't seem to work in NetBeans, how can I import code from another package? I can seem to import from the same package, but not a different one.

  • Fi validation -exclude tr code from other modules

    I am setting up a validation at the Fi line item level. Now it is restricting some documents comming from MM which we don't want to. Is it possible to exclude some of the transaction codes from other modules to not to consider this validation.
    I tried SYST-TCODE <> (T-Code from other modules like MM for eg: MIRO etc)
    But that does not seem to work.
    Does anyone know why and are there any options to get this done.
    Any help will be appreciated

    Hello,
    Please validate BKPF-AWTYP (reference procedure)
    For postings done in FI its, BKPF and so for others it would change.
    This would be simple.
    But for this check whether this field can be used for validation.
    This can be done by checking table GB01, if not change the settings to make this field available for validation.
    Best Regards

  • Question about access non-public class from other package.

    Hi, everyone!
    Suppose class A and class B are in the same java file of package pkg1
    -- A.java. So, A is a public class and B is a non-public class.
    If I want to access class B from another class class C and class
    C is in package pkg2. When compiling, an error occurs indicating
    that class B is not visible to class C.
    So, If I defined serveral classes in one java file and I want to
    access every class from other package. How should I do?
    (I think in one java file, there should be only one public class and
    only the public class can be accessed from other package.)
    Thanks in advance,
    George

    So, If I defined serveral classes in one java file and
    I want to
    access every class from other package. How should I
    do? As you already seem to know, there is at most one public class allowed per source file (at least, with javac and most popular compilers). So if you want more than one public class, you will need to use more than one file...

  • Calling methods from other classes

    I have a bunch of little java files in a folder, do I need to make a package in order to access all the methods in all the classes, or can I just make an instance of any of the methods because all the classes are in the same folder?

    HI,
    If your methods have a "public" modifier (and the class does too) then you can instantiate your classes as objects from that (so-called) "default" package in any other class or object in any other package and then call the methods on those instantiated objects as you please.
    If that sounds confusing... I'd seriously try the excellent tutorials at this site, especially "the java tutorial".

  • How to store Connection object and call it from other programs.

    Hi,
    I am trying to connect to the database, store the connection object and use this connection object from other standalone java programs.
    Can any one tell me how to do this? I've tried in the following way:
    In the following program I am connecting to the database and saving the connection object in a variable.
    public class GetKT2Connection {
       public static void main(String[] args) {
          String url = "jdbc:odbc:SQLDsn;
          String dbUser = "sa";
          String dbPwd = "sa";
          Connection kt2conn = Connection connection = java.sql.DriverManager.getConnection(url, dbUser, dbPwd);
          if(kt2conn == null) {
             System.out.println("Database Connection Failure!");
          else {
             System.out.println("Connected to Database...");
         GetKTConnectionObj.storeKT2ConnectionObj(kt2conn);
    } Here is the program to save connection object in a variable.
    public class GetKTConnectionObj {
       static Connection kt2Connection = null;
       public static void storeKT2ConnectionObj(Connection conn) {
       kt2Connection = conn;
       public static Connection getKT2ConnectionObj() {
       try {
          return kt2Connection;
       catch(Exception e){
          System.out.println(e);
      return null;
    }Now from the following code I am trying to get the connection object that is stored. But this is throwing NullPointerException.
    public class Metrics_Migration {
      public static void main(String args[]) {
         try {
        java.sql.Connection connection_1 =   GetKTConnectionObj.getKT6ConnectionObj();
         catch(Exception e){
    }

    kt2Connection is null. You need to store it first, to make it not null. Otherwise it will stay null forever. And why on earth are you trying to do this THIS way?
    If you are running the two applications separately, it wont work either.

  • Create DLL from labview and calling it from other application

    Hi Yuvish,
    1) They should be boolean inputs to your VI. But does it makes sense to provide a stop button input at the start of your VI? (THINK DATAFLOW!)

  • Calling Transaction from other system using RFC

    Hi ,
    I have one button on screen(say Screen-A), in ECC. when its pressed the transaction '/SAPAPO/BOPIN' gets called from APO.
    For calling transaction from APO I am using FM - 'ABAP4_CALL_TRANSACTION'.
    I want the initial screen of that transaction to retain some values which I fill on the Screen-A(the screen which has that button).
    When I call the transaction from ECC itself (ex. C006), the initial screen of C006 retains the value on Screen-A.
    I want the same to happen in case of calling transaction from APO.
    How to achieve this?  Would it need the changes in IMG (SPRO)?
    Please note that, Screen-A is initial screen of transaction 'md05' and I want to retain vaules of Material, MRP Area, Plant.
    Thanks,

  • Loading fails, when classes from other packages are referenced

    My applet follows a simple package structure.
    There's package P1 and there's another package in it P2 (P1.P2)
    P1 contains Applet class A.
    P2 contains another class C and interface I. C implements I.
    A contains a reference of C, which is initialized in the constructor. The use in the constructor of the A (the applet) is something like this
    public A () {
              reg = ToolkitRegistry.getEntry (); //where reg is a reference of type ToolkitRegistry.
              // some more code
              i = (I) C.getC (); //where i is a reference of type I.
    }Trying to load this applet throws error saying "Package Loading failed". Important is to note that the loading occurs successfully by commenting out this line           i = (I) C.getC (); //where i is a reference of type I. , without any other change.
    I understood this to be some problem with the AIDs assigned to both the packages while converting. Unsure of what's the correct way to assign the PIX values, I've been trying some permutation/combinations, it doesn't seem to work.
    Has neone already faced this problem & knows the solution? (The specs aren't much help)

    One more point ..... I mentioned commenting the statements, I DO NOT commment the other statements referencing the other package. This means that the loading IS succesfull, even when these two lines reside in there.
    1. import P1.P2.*; 2. private I i = null;Above two lines pass the loader. The object creation gets stuck.
    Wonder if the package references are actually alright, because JVM wud've treated both situations in a similar way. JCVM is ofcourse different but JCVM spec does not say nething abt this situation (rem: everything is public, so the access control restrictions also do not apply)
    are there ne instantiation restrictions? [In my case, it's in the constructor thread)
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   

  • Call event from other event or other vi

    I have LabVIEW 6.1.
    1. Can I call an event or a serious of events from another event? How can I do that? It doesn't matter if the events are executed after the event that called them is completed.
    2. Can I call an event from another vi? Let's say I have an event structure in a subvi. Can I trigger an event in the subvi calling it from the main vi? How would I do that?
    Thanks for your help.
    Jerome.

    Salutations,
    In reality, a program should only have 1 event structure. Or so someone much more knowledgable with labview has told me in the past.
    It's an important note to make that when running events or SubVi's, they will run until they are accomplished and then allow the next event or subvi to take place. So if you have multiple event structures, you must wait until one finished before the next one is run (This might...no guarantees, be avoided by multiple while loops and not locking the front panel on the execution of an event). Now, since you don't care, you can handle such a case. Just make multiple events in your one main event structure. I'm not sure what exactly you want to do, just make sure you "unfreeze" the front panel when you're messing with what handles what events.
    Hence, you could have a "run" button that's pressed and it goes about it's business. Then you could have a mouse down response, that you hit while your "run" process is still going, this will be, in a sense, logged and accomplished once the "run" task is done. Now, if you're looking for data to trigger another event, maybe I'd switch over to a case structure that's inside your event structure. For case structures, every case must have an output.
    Can you trigger an event in the subvi calling it from the main vi.... Excellent question... I'm not exactly sure when this would come up, but i'm not super experienced like some of the people around here. It may be possible, but i'd imagine a case structure would be more efficient. Like the ones in error handling. Pass the case to the subvi, it'll operate depending on what you want, and then continue along. Events seem most useful when dealing with events that occur on the front panel.
    Hope this helps,

  • Calling EJBs from other EJBs in other J2EE Server?

    How can I call one EJB on one J2EE Server from other
    EJB on other J2EE Server?
    Help me, please.
    Dmitry Tumanov

    Basically call the beans as if you were calling them in the same server through their remote interfaces. Get a InitialContext into the other appserver and then get the home object, narrow it and create a remote reference. You can follow the standard implementation just make sure that the InitialContext you create has the right properties, ie. context factory, urls, etc to the OTHER appserver.

  • Calling one t -code from other

    Hi all,

  • Calling repaint from other Class file.

    Hi,
    First of all i am pretty new to Java so I hope you understand what I am trying to explain..
    I am trying to create an applet which draws some polygons on the screen. For the drawing of these polygons I have created another class which is located in another package but the same project. I plan to use this second package as some kind of library so that i can simple call 2 or 3 functions in future applets to draw these polygons (which always have the same shape). In the library file i have created a contructor, a draw function and some other functions to change some properties. I also created a function that created a popup window as soon as i click on one of the polygons i have created. In the popup some buttons are available which change the color of the polygon. All this works fine, but the problem i have is the following:
    When i click a button the main class (in package 1) needs to be repainted for the changes to be visable. But the main class can always be a different one. Is it possible to check in the class in the library package, which class from the main package called the class, and execute a repaint() on that class. So i have the following situation:
    Package 1 (Applets):
    package applets;
    class myApplet extends Applet implements .... {
    private Tank tank1 = new Tank(20, 20, 100, 200);
    private Tank tank2 = new Tank(250, 20, 100, 200);
    public void paint(Graphics g) {
    tank1.drawTank(g);
    tank2.drawTank(g);
    public void mouseClicked(MouseEvent e) {
    tank1.openWindow();
    tank2.openWindow();
    Package 2 (Library):
    package applets.library;
    class Tank {
    public Tank(int xPos, int yPos, int height, int width) {
    public void drawTank(Graphics g) {
    public void openWindow() {
    new myWindow("Window1");
    public class myWindow extends Frame {
    public myWindow(String name) {
    show();
    public boolean action(Event e, Object arg) {
    return true;
    So what i want to do is: In class Tank in the public class myWindow in the method action, i want to call the repaint() of the class myApplet
    I hope my problem is clear to you, as you may have noticed i have a little trouble explaining it clearly..

    First of all thanks a lot for your reply and sorry for my way of programming. Like i said i am pretty new to Java, i am actually only programming for about 2 weeks and trying to learn from some examples on the internet.
    I dont really understand what you want me to do, is it maybe possible to give a little bit of sample code? That would help me a lot.
    Maybe some background information about the project will help a bit too.
    I work at a company that develops automation solutions. We program PLC's and SCADA systems. Now Siemens has some PLC's that support Java applets which make it possible to visualize industrial processes. Now i am trying to figure out if it is possible to start developing own java applets for visualisation in the future. Since most programmers here have no experience in any higher programming language i want to keep it as simple as possible, by developing libraries that do the most of the programming work for them.
    Now i want to create the first part of this library by programming some kind of storage tank. This tank always has a valve. when i click on the valve a popup should open with the operation button to open of close that valve. When a valve is opened it should be colored green and when its closed it should be colored gray or something. The Tank class has a couple of methods:
    drawTank(); to draw the tank in my applet,
    openValve(); to open the Valve,
    closeValve(); to close the Valve,
    After all this is created i want to be able to use this class in all my other classes and create a tank by simple making a new Tank object, draw it on my applet using the drawTank() method and open or close the Valve using the other 2 methods, however when i open or close the Valve the color of the valve should change so i must be able to call the repaint of all the classes that use my Tank class, but i want to do that INSIDE my Tank class.
    If there is another way of doing this i would love to hear so, but i would help me a lot if you can explain in a little bit of sample code. It doesn't have to be really long or detailed.
    Thnx in advance
