How java handles package/class names

I am developing a strategy for internationalizing our company's middle-ware product. While I have no problem with the GUI's, exceptions, log files etc, I have no concept of how things like classpaths and packages can be specified in an asian language.
For instance, if I have configuration information of com.abccompany.mypackage.MyClass, what will this look like to the asian user? Will they be able to change it to perhaps com.abccompany.mypackage.MyClass2 by entering localized data in Chinese or Arabic? I don't understand how this part works. On the command-line, will they type English script names? Do they run commands like so: java -cp com.abc.pkg1.jarfile.jar MyClass? Will my english filenames, packages, etc be represented in asian characters?
We have a lot of configuration information that specify java classes as String data. I am concerned about the ability to modify this data and have it work correctly in languages that do not use the ascii character set. Is this something I need to be worried about?
I appreciate any input. Thanks in advance.

You do not need to warry about configuration information of com.abccompany.mypackage.MyClass
and command-line no matter what languages used in Asia. Asian users also type in English script names or java -cp com.abc.pkg1.jarfile.jar MyClass as you do so. The only thing you need to note is
that any text strings or messages which you want to show on any panel/dialog/window/frame and so on should be store in a resource file for internationalizing.

How Java handle duplicated class?

I am trying to send out email using SUN JavaMail. However, an old version of JavaMail was shipped with Oracle AppServer 10 R2. If I package the new JavaMail into the WAR file, the old JavaMail is still functional, and cause problem to my program. Is there a way to tell the AppServer to use the JavaMail in my WAR file instead of the old one shipped with the server?
Thanks very much!

Hi,
does this help you? It's from an older vesion but might wor kin your case.
How do I setup OC4J to load local classes packaged in my Web Application overriding System classes or classes in the higher level?
OC4J 9.0.3 has a configurable option to load local classes first, overriding classes at a higher level. You have to include the following to directive in the orion-web.xml for your web module to ask OC4J to load local classes:
<web-app-class-loader search-local-classes-first="true" />Timo

How do I find class name I should import for java method name

If I have the class name I know how to look in java docs list for methods.
If I have a method name but don't know the class,
how do I find class name I should import to use the java method name?

I'm not sure the other reply answered your question. If you truly don't know the class name, one approach would be a Google search. Another approach works if you have an IDE. Eclipse, for example, can find the class for you (assuming it's on your classpath) & automatically import it for you. Ctrl-Shift-O normally does the trick.

How to get the class name static method which exists in the parent class

Hi,
How to know the name of the class or reference to instance of the class with in the main/static method
in the below example
class AbstA
public static void main(String[] args)
System.out.println(getXXClass().getName());
public class A extends AbstA
public class B extends AbstA
on compile all the class and run of
java A
should print A as the name
java B
should print B as the name
Are there any suggestions to know the class name in the static method, which is in the parent class.
Regards,
Raja Nagendra Kumar

Well, there's a hack you can use, but if you think you need it,Could you let me the hack solution for this..
you probably have a design flaw and/or a misunderstanding about how to use Java.)May be, but my needs seems to be very genuine..of not repeat the main method contents in every inherited class..
The need we have is this
I have the test cases inheriting from common base class.
When the main method of the test class is run, it is supposed to find all other test cases, which belong to same package and subpackages and create a entire suite and run the entire suite.
In the above need of the logic we wrote in the main method could handle any class provided it knows what is the child class from which this main is called.
I applicate your inputs on a better way to design without replicating the code..
In my view getClass() should have been static as the instance it returns is one for all its instances of that class.
I know there are complications the way compiler handles static vars and methods.. May be there is a need for OO principals to advance..

How to create package class ..

Dear firend,
I have created the packge file under /home/in/package/Time1.java
Time1.java:
package in.package;
public class Time1 {
public static String name="Package Testing";
public void assign_name(String val) {
name=val;
public String get_name() {
return name;
public static void main(String args[]) {
Time1 obj=new Time1();
obj.assign_name("Testing");
System.out.println(obj.get_name());
Then I have tried to access this package file from home directory.
package_test.java
import co.in.bksys.packaging.Time1;
*public class package_test {*
* public static void main(String args[]) {*
//in.package.Time1 time_test=new in.package.Time1();
Time1 time_test=new Time1();
* time_test.assign_name("Leslie Samuel");*
* String my_name=time_test.get_name();*
* System.out.println(my_name);*
I have compiled this file from the home direcory.
*$ javac -classpath in/package/ package_test.java*
It was displayed this below error:
=========================
* package_test.java:1: package in.package does not exist*
import in.package.Time1;
* ^*
package_test.java:8: cannot access Time1
bad class file: in/package/Time1.java
file does not contain class Time1
Please remove or make sure it appears in the correct subdirectory of the classpath.
* Time1 time_test=new Time1();*
* ^*
*2 errors*
but if i used this below line in the package_test.java file insted of using this Time1 time_test=new Time1(); .
It will work perfectly.
in.package.Time1 time_test=new in.package.Time1();
I know that its expecting some format of class file like , in.package.Time1.class inside the in/package/ directory.
It wasn't there so displayed this error.
How to create this knid of class file to appropriate directory ?
How to make my program execute without giving full package name like , in.package.Time1 time_test=new in.package.Time1(); ?
Thank you.

Package is a reserved word in Java. Name your package something else.

How to find the class name of the BO

HI
How to find out a class for a business object.
For example for the Business Object FORMABSENC i want to find out the class name.
iam not able to find out from se24 or swo1.
Or please suggest me how can i use the method createbapistructure of this businessobject.
Regards
vijaya

Hello Vijay
When you double-click on "method" AbsenceForm.CreateBapiStructure (transaction SWO1) and switch to tab ABAP you see (on ERP 6.0) that the field Name is empty meaning this BO "method" has not yet been implemented.
Other methods are implemented by modules of function group SWXA. Checking package SWX you will see that there are no suitable classes around for this object.
Final remark: Methods of business objects has just a semantic meaning and has nothing to do with object orientation (i.e. classes).

How to get the Class name of an API method?

Like most of us, it's difficult to know where every method within a Java class is. Also, many of the same methods are scattered throughout Java Classes. I know of two methods that retreive this... getClass().getName(). But, you must have an object to use these. Is there a way to find out what Class contains a method or Class variable thru an Applet or Java Application?? Obviously, I can look at API Docs; but this takes time.

How 'java' handles classname passed to it

Hi,
After compiling the .java file, the .class is passed to 'java'
and that runs the program.
Does the 'java' work this way: when we give "java classname", 'java'
strictly would search for classname.class and proceeds thereafter,
The reason i got this doubt is when i gave a command "java
classname.class" an error was raised pointing no class definition.
Thanks for your time.
Kris.

When the java virtual machine looks for a class it uses a ClassLoader. What the default classloader does is:
1) Converts any dots in the "fully qualified name" to the appropriate path separater / or \ depending on the operating system.
2) If it's an inner class, the inner class name is separated from the outer class by a $
4) adds .class to the end
5) Walks along the CLASSPATH. For every directory on the CLASSPATH it adds the string processed above and looks for a file. For every .jar file it tries to find the entry of the same string.
Note "." in a classname is used to separated package name from class, as in java.util.Map, for example. "classname.class" would look for a class called "class" in a package called "classname".
You can't compile a class called "class", by the way, because it's a reserved word.

How to change generated class name when create binding files.

I have a dtd file, which has lines like this:
<!ELEMENT rights (
     %plain-text;
     | rights.owner
     | rights.startdate
     | rights.enddate
     | rights.agent
     | rights.geography

     | rights.limitations
     )*>
     <!ELEMENT rights.type (%plain-text;)*>
when i use xjc to create binding files, I got an error:
trying to create the same field twice: value.
I suspect that the reason is because the name of rights and rights.type.
so, i'd like to know how can i control the generated class name. for example, i want to generate a class RightTypeEle for element rights.type. how can do that?
btw, i use latest version of jaxb.
Thanks in advance.

Do you know of a good book about the "middle ground" (ie, these service layers)? I understand it empirically, but haven't had a lot of exposure to it.

PS: Apologies. Edited my previous post, presumably while you were composing your reply, when I finally realized what '.filed' meant.Most of my work is in web development, never been a DBA :) . The biggest 'concern' in my shop is 'separation of concerns'. The UI group reports up to a different IT head, the DB group reports up to a different IT head and so on. The looser the coupling between these systems, the lesser the project costs (Integration, QA etc) are. Martin Fowler's books contain good information about separation of concerns in an enterprise environment. The two books which i recommend are

How java extends Object class?

It is true that we cannot extend more than one class, it is true that java inherits Object class implicitly (if not explicitly) and it is also true that we can extend class X in class Y.
My question is if java does not support multiple inheritance (directly, using extends) then how does it extends Object (implicitly) and my class X (explicitly)?
In other words how does java inherits Object along with our specified class?
Thanks in advance.
Manish

Java does support multi inheritance!Yes I know java support multiple inheritancethrough
interfaces but what I meant was you cannot inherit
multiple classes using "EXTENDS".and that is correct. Do you still have a question
regarding this?Nop, actually due to over-concentration and over-thinking on this topic while reading I lost the track and asked this question.
Thanks

How to find out class name

Hi folks,
Can anybody help me, I got stuck on this problem.
I need to find out the className of the class, which is specified
by ordinary filename.
In other words:
User gives me filename (something.class) and I need to find out
classname (I just need to create an instance of this class)
Thanks a lot.

This will read the class name from a class file.
