How to create package and import from jar file?

Hi all,
I am writing a software and I am not sure how to create a package for the classes.
Say I have two classes in the same directory as follows:
testA.java
==========
package AB;
public class testA
public static void main(String[] args){
     testB myB = new testB();
     System.out.println("A test");
testB.java
===========
package AB;
public class testB
public testB(){
     System.out.println("B constructor");
both file compile without the package heading;
both file compile using: javac -classpath .\ *.java
Question 1:
I cannot run testA by: java -classpath .\ testA
I think it is a syntax error. What is the correct one?
If I run testA by: java testA
The only output I get is: A test
But I am expecting: B constructor /n A test
What went wrong?
Question 2:
I need to use APIs of another software. I have downloaded a .jar file (xxx.jar) with all the classes in it. And I have put "import xxx.*;" in my source file. But the compiler complains about the importing. What is the right way to copmile it?
I have read a couple of tutorials but they don't answer my question.
(I am using windows2000 and don't have the classpath variable.)
Hope some one can help.
Thanks a lot

Try moving testA out of the package and importing 'AB.*;'
If you have:
./testA.class
./AB/testb.class
Then to execute testA from ./ type: java -cp . testA

Package and import

I have a problem about the syntax package and import . If i create a class file that call "Play.java" and keep it at directory call "test".
Now , i create the main file that call the "Play" class and this current file keep at directory that call "demo". That is mean the "demo" directory includes the main file and "test" subdirectory. So , what should i do ?
Thanks.

I would assume that you have two files and want one of them to belong to a package. If the main directory you are working out of is c:\demo\ (/demo/ on a *nix system) you would have the following in that directory.
c:\demo\MainProgramClass.java
c:\demo\test\
The c:\demo\test subdirectory would then contain a class called Play.java (c:\demo\test\Play.java)
Right?
That means the Play.java class belongs to the package 'test', so you would include the following at the start of the Play.java file:
package test;
Your MainProgramClass.java file (or whatever you named it) should contain the following import statement:
import test.*;
This will import all of the files in the test package (basically everything in the test directory). You could also use 'import test.Play;' if you only want to import the Play class.
Hope this is what you wanted,
Ryan

How to make a package and import it later

Hi folks,
this is a very basic question but it is not working to me so i will appreciate your comments.
I had programmed many classes that are going to be used in many projects so they must be part of a library. Tell me whether or not this procedure is correct ?
Compile those classes into .class files. Create a package with the jar application putting the .class files into a single file called my_utils ( .jar or .zip ?). Import the package from other projects using the import directive and storing the my_utils file in the project's library directory. Is this correct ?
Many thanks in advance
Marla.

If you want to create a package and then put the package into a jar file, first compile into .class files (in appropriate package directories), then jar all of the .class files.
Here's a link for a tutorial on packages. http://java.sun.com/docs/books/tutorial/java/interpack/packages.html
Here's a link for a jar file tutorial. http://java.sun.com/docs/books/tutorial/jar/index.html
You do not have put the .class files into a jar. Java packages are used for organizing classes, managing class name space, and controlling access to classes. Java jar files are a way to put multiple classes into a single file while compressing the content. Jar files can contain multiple packages and packages do not have to be inside of jar files.

Very Basic Package and Import question

Thanks in advance ...
- I read/tried all tutorials and documents on the matter
- the programs are from "Java 2 from scratch" book (Steven Haines)
- I suspect the problems result from using new SDK 1.4.2 version versus SDK 1.2.1 (that the book uses)
OK, here we go :
package Stock1.PortfolioTotalsPanel;
- first line in PortfolioTotalsPanels.java file
package Stock1.StockTablePanel;
- first line in StockTablePanel.java file
package Stock1.StockTableTabPanel;
- first line in StockTableTabPanel.java file
--- then:
Import Stock1.PortfolioTotalsPanel ;
Import Stock1.StockTablePanel ;
NOW : I guess I have to compile 'PortfolioTotalsPanels' and 'StockTablePanel' on their own - which I did successfully and kept the '.class' in the same directory (folder) - Stock1
When trying to compile 'StockTableTabPanel.java' file...
StockTableTabPanel.java : cannot resolve symbol
Symbol : class StockTablePanel
Location: class Stock1.StockTableTabPanel.StockTableTabPanel
StockTablePanel stockTablePanel = new StockTablePanel();
...and the same error message for 'StockTablePanel' class.
- I noticed the last line has 'stockTablePanel' instead of 'StockTablePanel' ...not sure if it makes a difference..same with the 'portfolioTotalsPanel'
I'm out of ideas...HELP !!

package Stock1.PortfolioTotalsPanel;
- first line in PortfolioTotalsPanels.java file
package Stock1.StockTablePanel;
- first line in StockTablePanel.java file
package Stock1.StockTableTabPanel;
- first line in StockTableTabPanel.java file
--- then:
Import Stock1.PortfolioTotalsPanel ;
Import Stock1.StockTablePanel ;
NOW : I guess I have to compile
'PortfolioTotalsPanels' and 'StockTablePanel' on their
own - which I did successfully and kept the '.class'
in the same directory (folder) - Stock1Both of your source files are in a directory named Stock1, right? Change directory so that you are in the directory above Stock1:
c:\javastuff\Stock1> cd ..
c:\javastuff> javac Stock1/StockTablePanel.java Stock1/PortfoloiTotalsPanels.java
to run them, run them from this root directory:
c:\javastuff> java Stock1.StockTablePanel
assuming that that class has a main() method.

Test Packages and import library error.

Maybe somebody can help me. I'm working with a developer who created our project in NetBeans and uploaded to a CVS. (I am using JSE8) Because he did this it did not generate a "Test Packages" source folder. When I go to my local machine and create a folder named "test" the project creates the correct icon folder.
1. At this point I select generate test (junit test) of my class in the package com.ca.web.utils
2. in Test Packages it creates a package named com.ca.web.utils and then the test class classATest.
3. My imports would not reference the class in the source package it only reference my TestClass in the Test Package.
for example,
Src
com.ca.web.utils
classA
test
com.ca.web.utils
classATest
and in my classATest when i attempt to reference classA
import com.ca.web.utils. (only class in intelisense is classATest)
Can anybody help?

Seems if we add the "test" file package to the CVS itself that fixed the problem.

Please tell how to use package and import?

Hi,
My classes are in different packages
for eg
package manage.ui
package manage.data
package manage.layer
if I try to import
import manage.layer.*;
in a class in manage.ui
it shows
package manage.layer does not exist
Please help to find the problem?????

Are your classes placed in a folder stucture that mirrors the package structure? So, like this:
-manage(folder)
--ui(subfolder of manage)
--data(subfolder of manage)
--layer(subfolder of manage)

Java Packages and Imports

Hi,
I have 2 java classes
A.java
B.java
### A.java ###
import B;
public class A
public static void main(String[] args)
public class B
public void foo()
when I compile B , it works fine, but when i compile A.
it gives following error
'.' expected
why java doesn't allow to create & import a class without package, is there any workaround to resolve this issue
this is a sample code i have posted, but actually I am facing the same problem in my current project. even if i include that class in classpath error doesn't go away.
Please suggest what can be done to resolve this issue.
Thanks in advance.
NP

- the default package (the package with no name)It does? Not for me.Gosh, you're right, it doesn't. Sorry.
Actually, I never use it, my post was a copy/past from damned tutorial...

Export and Import a Keyword List

Yesterday I exported the keyword list and then acted on the suggestion from LightroomSecrets site to 'organize' while it is in text format. This went very well using a text editor.
The IMPORT doesn't overwrite the existing list. It merges INTO the list.
So now I'm still scrolling up and down collecting the keywords that are stand alone to undo and then put a checkmark beside the subkey in a category. I would have been wiser to have reorganized a few and repeated the export,import <grin>
If keywording is promoted as such an important feature and a main item for management in Lightroom then, it would seem to me that the 'LIST' itself could have been designed in a more efficient manner...Such as : a right click menu...or a browse and choice to move to...
I suppose the architects of this list assumed users would have their keywording planned out ahead of time. Never assume <grin> I've only now (V1 to V3.4.1) got my head around the category concept so much reorganization required. Scroll up and down and zoom past the category wanted....not an exercise I can stay with for long periods of time <LOL!>

Keywords are kept in the main database file and when you create a new library, you create a new database.
The only way I can think of to what you want is to select a single pic and give it ALL the keywords, then use iPhoto Library Manager to move that pic from the old library to the new one. iplm is the only way to move pics and metadata between libraries while using v6. (hmm, another reason to upgrade.)
And, as I mentioned in my other post, if you're a "keyword fanatic" then check out Keyword Manager

Import packages and Compilation issues

hello,
I am trying to compile and import a package in eclipse but it is not working.
Any helpful links or feedback would be helpful.
In the left pane is package explorer.
I right clicked and imported the apache commons .jar files.
The source .java files are in the same project folder.
On the top navigation in Eclispe the Project Button is not showing the build project accessible.

Your problem is really vague. It´s too generic and visually. Please use technically correct terms. Also please tell what error message exactly you got.
As far it sounds like that you don´t understand how classpaths work and how the Eclipse´s buildpath is related to that.

In the advance tab of each task there are some script logic already populated. please find attached the details of the script logic written under each of the tasks like MD_Source, concvert and target .
I have not done any chnages in the script inside the task .
But when i run the package , I have selected a dimension 'Entity' but in second prompt ,it ask for a transformation file , and syatem autometically add the file ... \ROOT\WEBFOLDERS\COLPAL\FINANCE\DATAMANAGER\TRANSFORMATIONFILES\Import.xls
I have not changed anything there
in the next prmpt , it ask for a output file ..and it won't allow me enter the file name .....i
Not sure how to proceed further.
I shall be greatfull if someone guide me from your experiance how to set up a simple the data manager package for master data export from dimension . Should I update the transformation file in the script for import file and output file in the advance tab. how and what transformation file to be created and link to the data manager package for export / import .

1. Perhaps you want to consider a system copy to a "virtual system" for UAT?
2. Changes in QAS (as with PROD as well) will give you the delta. They should ideally be clean... You need to check the source system.
Another option is to generate the profiles in the target system. But for that your config has to be sqeaky clean and in sync, including very well maintained and sync'ed Su24 data.

OWB 9.0.3.37 and imported plsql packages

I have some problems in owb version 9.0.3.37 with imported packages.
I can't delete a procedure/function in the imported package,in the package body I can do this .
The only way do delete procedure/function is do delete the package and re-import it from the db into OWB.
Problem then is that when I valid a mapping I must reconcile inbound the transformation (link broken).
Is there not another way to do delete function/procedure from a imported package.
Is the import of packages in the new version 9.2 still possible?

Hi,
There is an internal reason (validation) why we cannot allow you to delete functions from a package that you imported. That model is still the same in the latest production release.
Thanks,
Mark.

BPC 7 SP3 and Import Excel package

Hi,
I use VPC 7 SP3 (with SQL Server 2005) and I have some problems with the standard package named "Import Excel". The following error is returned:
Package Error Events:
ErrorCode = -1073450901
Source = ExcelToText
SubComponent= DTS.Pipeline
Description = "component "EXCELFILE" (1)" failed validation and returned validation status "VS_NEEDSNEWMETADATA".
Here is the parameters:
%XLFILE%     /ECOS/COMPTABILITE/DataManager/DataFiles//EXPORT_COMPTABILITE.XLS
%SHEET%     COMPTABILITE_CIBLE

%CLEARDATA%     1
%RUNLOGIC%     0
%CHECKLCK%     0
Any ideas?
thanks,
Romuald

Hi,
here is more information. The Excel file I try to load has different columns from the standard ones (I have an HYP dimension and no INTCO dimension). I have specified the list of columns in the package parameters interface. It seems that these values are not used by the package. I think that the package waits for a file with the standard columns, no less, no more. It works fine with BPC 4.2 (I use the standard Import Excel package and the file is well loaded).
thanks for your help,
Romuald
