Moving Bean-class to different package

Hi,
For deployment reasons i need the Bean-class in a different package, seperated from package where the Remote and Home are located. I'm not sure how to do this in VisualAge 3.5p2. Simply moving doesn't work.
Hope someone can help,
Maarten

It sounds a little bit strange. Do you want them in packages with different names, like you have bean-class in com.mycompany.project1.mybeanclasses and have the Remote and Home classes in com.mycompany.project2.myremotehomeclasses? It seems possible if you right-click the class you want to move and select 'move', you can move it to a new package. This will be able to separate them.
Just curious, I think VAJ is very powerful concerning deploying EJBs already so what kind situation makes you want to separate the bean-class and interfaces?

Moving Model Class to different package

Hi,
How can i move the model class to a different package in CE 7.1
Regards,
Senthil

Hi Senthil
I thinks this should be possible to realize on the file system level.
- Find the folder where your model as well as the model classes are located.
- Search for all files (.) that contain the model class name. Typically it'll find (*.wdmodel and *.wdmodellclass). Change manually the package name within/near the found lines.
But why do you need to change the model class package separately from the model package?

Accessing a dll from classes in different packages

Hello java community,
I am new to Java and especially the jni so your help is greatly appreciated.
I am having trouble accessing a Windows native dll from classes in different packages. I placed the .dll in my ClassPath. I am able to loadLibrary successfully from class X in my 'common' package. However, when I try to access the same .dll from another class Y in package 'notsocommon'. I get an unsatisfied link error. I changed the X.h file to include common in the function definition (eg. Java_common_X_functionName) and I did the same to the Y.h file (Java_notsocommon_Y_functionName). I am able to work with the dll from the X class but not the Y class. I don't know what I am doing wrong. I am very new to Java, so any help is appreciated.
Thank you.

I apologize to everyone for posting this. I figured out my mistake, it was in the dll and not in the java. Also using
javah -jni notsocommon.Y
creates the correct header file.

Create Classes In Different Packages With Error-free Importing

Hello,
I'd like to create a class which inherits from another class from some other package. So I use "import" keyword to involve the class to build my new class on. However, I hope my new class can be in its own package which is different with one the base class is in. To make it clear, please see the example below:
There are two folders, with name c08 and c09 respectively, in C:\Java which I created for this case. I set the environment variable as C:\Java. There is no problem. Then I saved file "Inter.java" in C:\Java\c08. It's source code is as below:
package c08;
public interface Inter {
     void play ();
     void action ();
And another "Test.java" is saved in C:\Java\c09. Source code as below:
package c09;
import c08.*;
public class Test {
protected class PC implements Inter {
          public void play () {
               System.out.println("Play()");
          public void action () {
               System.out.println("Action()");
It was successfully compiled for "Inter.java". But when comes to "Test.java", it failed with error message of something like "Cannot find the interface Inter". I tried some other ways and I didn't get any results.
I hope to create a class using classes from some other packages while keeping the new one in a different package. How can this be done? (I am currently doing this in J2SE 1.4.01 under Windows XP Home Edition)
Thank you!
Best Regards
Felix

I copied and pasted your code as well as made c08 and c09 directories. I had no errors compiling. I am using NT, but it appears that your problem is Classpath related. You can try to CD to the C:\Java directory and compile using "javac c09\Test.java" That's the command I used.

Same class in different package

I am facing a design decision, I have a set of classes which defined the values of all variables. However, I realized that I need to prepare
separate set of these classes for different countries (as they may vary), i.e
my.package.us
     PriceList.java
my.package.ca
     PriceList.java
PriceList.java
===============
Public class PriceList {
public final static Price directFlightPrice = new Price(13500,2); // where 0 is the decimal places
public final static Price connectFlightPrice = new Price(11000,2); // where 0 is the decimal places
I am not sure how I can achieve this, would you guys please help? Thank you!

Isn't this more what you need? You don't want to create a new class, you should create a new instance of a class.
class PriceList {
    private Price directFlightPrice;
    private Price connectFlightPrice;
    private String country;
    public PriceList(String country, Price directPrice, Price connectPrice) {
        this.country = country;
        directFlightPrice = directPrice;
        connectFlightPrice = connectPrice;
    ... methods to use pricelist variables
class PriceListTest {
    public static void main(String[] args) {
        Map<String, PriceList> pricesPerCountry = new HashMap<String, PriceList>();
        // This is where you could load data from file and put it into a PriceList object...
        PriceList plUK = new PriceList("UK", new Price(...), new Price(...));
        PriceList plAu = new PriceList("Australia", new Price(...), new Price(...));
        pricesPerCountry.put(plUK.getCountry(), plUK);
        pricesPerCountry.put(plAu.getCountry(), plAu);
        // Use pricelist UK
        PriceList list = pricesPerCountry.get("UK");
}

Same class name, different packages

Let's say I have two classes called Team, and each are in their own package. I go to import a.Team and b.Team, what do I have to do to make this work?

Import them both if you need them both. When you go to use them, refer to them by their fully qualified name.a.Team aTeam = new a.Team();
bTeam bTeam = new b.Team();You don't really need the import statements from a programatic point of view, but it helps make your code more legible to other developers.

Moving a class into a package?

hi,
is there a way through which I can move an existing class inside a newly created package?
Best Regards,
Tarun

Hi Tarun,
Go to se80.
Give your classname by chosing the Class/Interface from the list box.
Then right click on the class->Other Functions->Change Package Assignment.
Then click on the pecil button to go to the cjhange mode. Give the name of the new package in place of the old.

Command Line Compilation of a Project with different packages

Hi,
I am trying to compile a project through command line, which has different packages with many classes in it. Now If I try to compile package by package It's complaining about other referenced classes of different packages. So I created .bat file, which includes all the packages, but it's complaining input line is too long.
D:\jdk1.3.1\bin>app.bat
My bat file is
javac -d d:\Application\build d:\Application\source\com\ibc\rules\login\*.java d:\Application\source\com\ibc\rules\lookup\*.java .................d:\Application\source\com\ibc\wid\events\*.java d:\Application\source\com\ibc\wid\frames\cust\*.java ...
and so on............
Is there any solution for this problem?
Thanks in advance....

I think the prefered and more elegant way to compile project including packages should be writing makefiles including their compilation, installation, deploying - rules ..
Make is really powerful, the maybe only weak-point is that there are some distribution of them, gnu-make, microsoft nmake .. which are slightly different, that made porting among platforms difficult.
The jakarta-ant was a new approach to this which uses xml parser to proof the dependencies, etc ..
Because I'm not familiar yet with xml & ant and as a in-blooded unix user, "make" is still my prefered way to do roject.
The easiest way to get unix environment required for using make in Windows platforms is to download the "unxutils". It includes make, bzip2, diff, ... and other unix-tools. Refer to this (found from search by google) :
http://www.weihenstephan.de/~syring/win32/
http://www.weihenstephan.de/~syring/win32/UnxUtils.zip
http://sourceforge.net/projects/unxutils/
For more documentation on how to write makefile, use make -tool, see
http://www.gnu.org/manual/
http://www.gnu.org/manual/make-3.79.1/html_mono/make.html

CMR Problem: Can you create CMR beans in different packages?

I created a Related Entity bean (ClassA) and unchecked the boxes that indicated it would create the other entity beans that were linked to the table.
I then created new Entity beans (ClassB and ClassC) in separate packages. I then set up the relationships in the ClassA Related module. Did the mappings, etc.
When I compile the application I get an error message indicating that the accessor methods (which the IDE auto-generates!) to what I have set as CMR fields can only be for CMP or CMR fields!
I've tried the PartsSupplier2CMR example and deployed it, but it is a flat tree.
Has anyone else come across something like this??
Thanks

I copied and pasted your code as well as made c08 and c09 directories. I had no errors compiling. I am using NT, but it appears that your problem is Classpath related. You can try to CD to the C:\Java directory and compile using "javac c09\Test.java" That's the command I used.

How to instantiate a class from a different package?

I am trying to instatiate a class in a package: a.b.c from another class in a different package: d.e.f
How could I do so?
I've already been trying many things but didn't manage to get it to work...

Did you include both jar files in your classpath? Use
the -cp option of the java interpreter to specify your
classpath.Well, I tried adding the jar file to the classpath, without any success...
String path = getClass().getProtectionDomain().getCodeSource().getLocation().toString();
               String finpath = "";
               for(int i=6;i<path.length();i++)
                    finpath = finpath+path.charAt(i);
               System.setProperty("java.class.path",System.getProperty("java.class.path")+";"+finpath+"mm.mysql-2.0.14-bin.jar/");That's what I did and it didn't work...
If you "unpack" the jars see if there is the correct
packages-folders symmetry...Yes, the classes are in the package-folders they should be in..

Home/Remote Interface and BeanName EJB in different Packages

Hi all,
I have a simple stateless session bean. Its Home and Remote interfaces are in X package and the BeanEJB in another. The files compile without any error. While I try to deploy it into J2EE ref implementation server using its deployment IDE, it throws up an rmic compilation error.
Error Details
File e:\j2sdkee1.3\repository\tejix\gnrtrTMP\POC2\General\SeabedHome_RemoteHomeImpl.java does not contain type General.SeabedHome_RemoteHomeImpl as expected. Please adjust the class path so that the file does not appear in the package General.
General is the package where the remote/home interfaces are located and Bean1 is where the BeanEJB.
Please suggest a solution
Thanks in advance
- Tejasvi

I think that there is no problem in having the remote and home interface in different packages. Are you sure there is no conflit between classes? I had the same problem because i had repeated classes in the same package. I know this looks stupid but it really happened.

Bean class not compliling

In a jsp page, a method of bean class is being called as.... <% beanId.BeanClassMethod( ); %> The problem with my program is that my bean class is not compiling. This bean method uses some "outside" classes which are in a single jar file. I have included that jar file in my classpath. The jar file includes classes in different paths like
a/b/c/x.class
a/b/d/y.class
a/b/e/z.class
Now what I want to know is whether I need to import these classes in my bean class and if yes how? I did import them as below:
import a.b.c.*;
but the compiler gives error as:
package a/b/c does not exists.
Can anyone figure where am I going wrong?

Follow the following steps and your problem will be sorted -
1. Find out if the mentioned class files are present in this jar file
Move to the directory where this jar file is placed.
Like, if your jar file is located in C:/myFiles/myjar.jar , move to
C:/myFiles > jar tf myjar.jar
when you execute this command, you will see the contents of this jar file as -
a\b\c\x.class
a\b\d\y.class
a\b\e\z.class
This ensures that required class files are located in this jar file.
If you could not see the required class files, you have caught the problem.
2. Ensure the directory hierarchy represents the package
First of all the set the class path to include the current directory in the classpath as-
C:/myFiles > set CLASSPATH=%CLASSPATH%;.
This appends dot(.) to the class path and this . represents the current directory.
Use the following command -
C:/myFiles > javap a.b.c.x
If you get the message like -
Class 'a.b.c.x' not found
it infers that this class doesnot have a package statement in it or the package statement doenot reflect the said directory hierarchy.
If you see the list of methods it means that everything is fine and the only problem is that directory n which this jar file is locate is not in classpath
Similarly check these other classes
C:/myFiles > javap a.b.d.y
C:/myFiles > javap a.b.e.z
Hope this helps

JSP can't find bean class!!!!!

First of all, I'm using jdk1.4 beta and Jakarta's tomcat version 4.0.1 release build.
Hello. I desparately need help. I have a JavaBean class ("CarBean.class") saved in %catalina_home%\webapps\root\myapp\web-inf\classes\com\wrox\cars\CarBean.class
I also have a jsp page saved as carpage.jsp in %catalina_home%\webapps\root\myapp\
So when I point my browser to http://localhost:8080/myapp/carpage.jsp, I get an internal server error. It appears it can't find the JavaBean class for some reason. I'm pretty sure I have my envionment variables set up right. I can get it to work, if I save the JavaBean class in c:\jdk1.4\jre\class\com\wrox\cars
Here's my JavaBean class source file:
package com.wrox.cars;
import java.io.Serializable;
public class CarBean implements Serializable {
public CarBean() {
private String make = "Ford";
public String getMake() {
return make;
public void setMake(String make) {
this.make = make;
and here's my jsp page:
<html>
<head>
<title>Using a JavaBean</title>
</head>
<body>
<h2>Using a JavaBean</h2>
<% com.wrox.cars.CarBean myCar = new com.wrox.cars.CarBean(); %>
I own a <%= myCar.getMake() %>
<% myCar.setMake("Ferrari"); %>
Now I own a <%= myCar.getMake() %>
</body>
</html>
This is the only thing I've modified in the server.xml file:
<Context path="/myapp" docBase="myapp" debug="0" reloadable="true"/>
I'm not new to java, just JSP. I just don't know why I can't get the jsp to locate the JavaBean class. I remember I used to have an older version of Tomcat and I recall not having any problems. It seems the Tomcat 4.XX is somewhat significantly different than previous versions. Perhaps I configured my Tomcat or server.xml wrong? Help would be greatly appreciated. Thanks.

Hi,
I am having a similar problem. I was wondering if you found a solution. The error I get is listed below. I have my jsp file at ../webapps/ROOT/myapp/web and my bean file located at ../webapps/ROOT/myapp//src.
Any help will be highly appreciated

Okay, first things first,
You did put the class into a package? good.
You did compile the class, so we no longer care about the .java file, only the .class file, right?
You read documentation on deploying applications in tomcat? If not, do a google search.
As was started earlier, keep things under Tomcat/webapps/yourapp at least until you get things up and working. Then worry about changing paths, mapped drives, and all those other things. Do this one step at a time and you will get there. Try to do too much at once and you will get lost and frustrated.
If you find the documetnation about deplying your applications in tomcat, you will also find info on how to change the absolute path of the context and/or host
A good place to start is: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/index.html

Class name and package name clashing

When i have a class and a package with the same name, I cannot access classes in the package. For example I have 3 classes and 1 package as below
- Test.java
- PackageName.java
+ PackageName // this is a directory
- MyClass.java
Below are the codes of .java files
Test.java
=======
public class Test { PackageName.MyClass a = new PackageName.MyClass ();}
PackageName.java
===============
public class PackageName{ }
MyClass.java
==========
package PackageName; public class MyClass { }
I can compile PackageName.java and MyClass.java but not Test.java. It says
cannot resolve symbol
symbol : class MyClass
location: class PackageName
PackageName.MyClass a = new PackageName.MyClass ();
But if I remove the PackageName.java, I can compile Test.java perfectly. I think when I use PackageName.MyClass, java thinks that I try to access an inner class MyClass of PackageName class, and that does not exists. Is there any way to solve this ambiguation, other than making the package name and class name different? Thank you very much.

This works fine: just add an import to Test.java.
import PackageName.MyClass;
public class Test
    public static void main(String [] args)
        MyClass a = new MyClass();
public class PackageName {}
package PackageName;
public class MyClass {}It's a pretty wacky, useless example, but it works.
Plus I thought inner classes would have a dollar sign in their .class file names. When I compile this:
public class OuterClass
    public static void main(String [] args)
        OuterClass outer = new OuterClass();
        System.out.println(outer);
    public String toString() { return "I'm an OuterClass"; }
    class InnerClass
        public String toString() { return "I'm an InnerClass"; }
}I see two .class files: OuterClass.class and OuterClass$InnerClass.class
Why make up examples like this? It's hard enough writing code, and it's easy to disambiguate for the compiler.
