Java package question

This is a follow-up to the following topic: Code sharing between applets
If I organize my source code in Eclipse with JCOP plugin the following way:
package A;
package A.B;
Where package A contain common code, and package A.B contain the applet code - is there a way to combine these two packages into one CAP file? Currently, my toolchain produce two CAP files (one for package A and one for package A.B), and I have to upload both into the card. I'm really looking for a way to structure the source code this way, but still be able to produce just one CAP file containing code from both package A and A.B.

HI, One package will always be generated into one cap, so you can not generate two package into one CAP file

  • Problem finding native methods in java packages

    Hi,
    I have a java class which uses some native methods written in OCamL. I wrote a C file which calls the OCamL code, and created the corresponding shared library using the jni. I then tested my java file and everything works fine, I can nicely call the OCamL functions. However, I need this java file to be included in a package, but whenever I add the line:
    package somepackage;
    on top of the java code, my java file simply doesn't seem to find the C and OCamL implementation anymore :
    javac -cp :./path/of/somepackage
    -Djava.library.path=/full/path/of/somepackage MyProgram args
    Exception in thread "main" java.lang.UnsatisfiedLinkError:functionName
    at somepackage.ClassName.functionName(NativeMethod)
    I have of course put everything (java, C, .h , libsomelibrary.so, and OCamL files) in a directory called somepackage, and written another java file which creates an instance of the first one from outside the package, imports the package, and calls its methods in main(). It just doesn't work anymore.
    I then added a simple hello-world function (not C nor OCamL code) to the java file inside the package. And when invoked from outside, it worked. Question is then... Am I forgetting something to be done, in order to get C and CamL files efectively included in the java package (same as "package somepackage;" in C or OCaml, perhaps)??? Why isn't the java file able to find them inside its very own directory (having into account that without the package definition it worked well)?
    Thanks,
    PS Im using jsdk 1.4.1 on lunyx redhat 8.0

    Did you change the name of the function in the library, too?
    If the function name was
    "Java_YourClass_functionname",
    it should be now
    "Java_path_to_your_package_YourClass_functionname".

  • Java package - money

    good evening guys,
    i am finding a piece of work extremely tough going at the moment and wondered if i could get any hints/help on where im going wrong. i am aiming to produce a package (money.java) which could be used in order to produce arithmetic calculations on sums of money.
    The code i have at the moment is:
    MONEY.JAVA:
    package java;
    public class money
         private int data1, data2;
         public money()
             data1=0;
             data2=0;
         public money(int value1, int value 2)
              data1 = value1;
              data2 = value2;
        public void addMoney(int value1, int value2)
              return value1 + value2;
         public void subtractMoney(int value1, int value2)
              return value1 - value2;
         public void divideMoney(int value1, int value2)
              return value1 / value2;
         public void multiplyMoney(int value1, int value2)
              return value1 * value2;
    }MONEYTEST.JAVA
    import java.money;
    public class MoneyTest
        public static void main(String [] args)
             money p = new money(10,20);
             System.out.println("The total is " + p.addMoney());
    }I think i may need a 'toString' method? and also, is there any way of covering errors? im sorry if these problems are trivial. I have various books, but can't seem to use them in this case.
    Thank you for any feedback.
    Jess

    That's a class, not a pakcage.
    Do you need a toString? There's already a toString defined on Object that you inherit. It's not very useful though. If you want to show something more meaningful when you do, say, System.out.println(aMoneyObject); then yes, you'll need to override toString.
    http://developer.java.sun.com/developer/Books/effectivejava/Chapter3.pdf
    What are data1 and data2? Those are meaningless names and you never use them.
    As for handling errors,
    http://java.sun.com/docs/books/tutorial/essential/exceptions/index.html
    It's not clear what you're trying to accomplish, and your questions are rather vague, so it's difficult to provide useful advice.

  • NoClassDefFound error when using custom Java package in scripting QPAC

    Hi,
    I compiled a little Java-package (.jar), which contains a class that uses
    com.adobe.workflow.datatype.form.FormDataTypeInstanceImpl.
    I put my library in the lib folder of JBoss (...\server\all\lib).
    Then I'm was trying to invoke my custom class in the scripting QPAC. But I'm constantly getting the error message
    NoClassDefFound com\adobe\workflow\datatype\form\FormDataTypeInstanceImpl. I already put
    adobe-wkf.jar (and various others) in the lib folder of JBoss. Without ever succeeding. Unfortunately.
    I'm going mad about this.
    Is there a way to address a custom package in the scripting QPAC, which uses
    FormDataTypeInstanceImpl?
    Steve

    Removing the LiceCycle jars from the lib folder did not work. I still get the same error message.
    What I wanted to do is provide some basic utilities, without having to spend a lot of time designing QPAC user interfaces.
    My utility class contains methods like this one:
    @param 
    pFormData
    @return
    @throws 
    ParserConfigurationException
    @throws 
    SAXException
    @throws 
    IOException
    public static 
    org.w3c.dom.Document formToXml
    FormDataTypeInstanceImpl pFormData
    throws 
    ParserConfigurationException, SAXException, IOException 
    byte
    data = pFormData.getXFAData
    InputStream objXMLInputStream = 
    new 
    ByteArrayInputStream
    data
    // create new Document object
    DocumentBuilderFactory objFactory = DocumentBuilderFactory.newInstance
    DocumentBuilder objBuilder = objFactory.newDocumentBuilder
    org.w3c.dom.Document objDocument = objBuilder.parse
    objXMLInputStream
    return 
    objDocument;
    Even without ever invoking the aforementioned method, I get the error
    NoClassDefFound: FormDataTypeInstanceImpl. Which is pretty weird.
    Do I have to write my own classloader?

  • How to find classes in a java package

    i am writing a java IDE. i want to extract all class names from a java package eg. java.lang (through coding). how can i do that.
    Thanks in advance

    File file = new File("path to your jar file");
    JarFile jf = new JarFile(file);
    Enumeration e = jf.entries();
    ZipEntry ze = null;
    while(e.hasMoreElements()){

    you have to understand java.util.jar java.util.zip packages for working with jar/zip files.

  • Problem with Java-Packages in JavaFX-Scripts

    Hello!
    What I'm trying to do is using a class I've built in my project in a JavaFX-Script, my problem is that the compiler keeps telling me my package wouldn't exist.
    My filestructure is basically the following:
    src
    |-com.foo.java
    |-- MyClass.java
    |-com.foo.javafx
    |-- MyFXScript.fx
    I've tried importing the package or just writing the fully qualified classname when trying to create an instance, the messages didn't differ. I'm not at home right now so I don't remember the exact compiler-message, but it was something like "Package does not exist: com.foo.java".
    Any ideas? :-)
    Kind regards,

  • Java packages and dependency

    When java was being developed, what was the philosophy behind allowing packages to be mutually dependent?

    Hello Steve,
    The Acyclic Dependencies Principle tells us that no cycles should exit in a model depicting the dependencies between packages. From what I can gather this is useful when developing large software systems, as each package becomes a viable work unit for an engineer or small group of engineers to control as a series of releases. If the ADP is not complied with, cycles may exist in the dependencies between packages. If a change is made to one of those packages within a cycle, then an ugly situation develops as the repercussions of the change are looped through the cycle back to its source and so on.
    The thing is though, during my readings I came across a statement that said Java packages were mutually dependent. I was just wanting to know why a language that utilises object oriented technology, left the practice of the ADP up to the descretion of the developer? Is the full implementation of ADP on a software system an ideal world scenario?

  • Java package and c++ header files

    What is the difference between importing java package and including header files in c++?

    I do not know .. have been away from C/C++ for a long time...
    As much as I remember you can only import one header file each time... also when you import a header file you can just call methods from the header file automatically ...
    However I could be very wrong on this .. really lost touch from C/C++ ...

  • Just Starting out with java packages

    Hello,
    I'm a beginner and I'm starting out with java packages.
    I wrote two simple .java files, one test program and one containing a simple class.
    Both files are compiling without errors but When I run the program I get an error NoClassDeffoundError.
    I use the import <package> statement And I think I'm using the CLASSPATH variable correctly.
    SET CLASSPATH=d:\nopol
    path for the .java containing the test class is:
    d:\nopol\utilities \myapp.
    In the test file I use "import utilities.myapp.*.
    I would be very happy if anyone could help me
    Thanks beforehand
    Nopol.

    The test file should be in d:\nopol, if it's not a part of your package utilities.myapp. Everything should be compiled from d:\nopol, the test class with "javac ClassName.java" and the class in the package with "javac utilities/myapp/ClassName.java".
    Your classpath seems fine for now, though. But yes, do add the period there, otherwise you could run into problems later.

  • Use of Java packages in Java stored procedures? (Oracle 10.2)

    Hi all-
    Does Oracle's Java stored procedures support Java packages? In all the examples I've seen, packages are never used, and when I added one to a test file, it compiled it just fine, but referencing the class from the package itself resulted in a compiling error.
    In other words, it seems to make absolutely no difference if I preface my Java class with
    package com.mycompany.whatever;
    and while I can "import com.mycompany.whatever.MyClass" in another Java file, it seems to not care at all whether I do so or not.
    Thanks for any clarification,
    Ilford

    Hi Ilford:
    Sure you can use fully package notation in your Java classes.
    Look at this Java source code:
    http://dbprism.cvs.sourceforge.net/dbprism/cms-2.1/src/com/prism/cms/core/
    All of them are Java Stored procedures.
    Best regards, Marcelo.
