How to get context information in your own class

Hi,
I'm new to Java and I'm trying to create my own class which stores some constants like for example mailServerHost. The class would look something like this:
public class AppSettings {
private static String mailServerHost="localhost";
static{
if(###online-server###)
mailServerHost="another mail server";
My problem is the if(###online-server###). I don't know how could I find informations about the underlying server.
Is there any way to find out informations about the context(server)?
Thanks,
IMIA

Do you still need ?n this case 2 different
property-files (one for dev and one for
online-servers).Yes, but they would have the same name. ;-)
After all when you need to load one
of them you'd still need in your AppSettings class on
which server your application is running. So I'd
still need that information.No, you use a fixed name, e.g. server.properties, for the config file.
You might find class java.util.ResourceBundle interesting.

I am new to Mac Pro but am purchasing one online. can anyone tell me how to get the information from my Toshiba onto the Mac. there are no stores in the state I live in. Do I need to find a location and will they do a transfer from my I Tunes etc?

I am new to Mac Pro and am purchasing one online tonight. Can anyone tell me how to get my information - Itunes, photos, and videos transferred onto the Mac from my Toshiba. the state I live in doesn't have an Apple store but I could take it to Minneapolis when I go. Any ideas where to begin?

You might profit from a visit to a Minneapolis Apple store. With a brand new Mac, I think they will be most helpful - not just with transferring files, but with other advice as well. And I strongly recommend you invest in a back up drive. The Apple folk can help with that as well.

Thanks all for the help.
Here is my solution. A mix from Julian and Thomas.
In future I will encapsulate the code in a function module.
DATA: BEGIN OF usr_tabl OCCURS 10.
        INCLUDE STRUCTURE uinfo.
DATA: END OF usr_tabl.
DATA: th_opcode(1) TYPE x.
DATA: LV_TID LIKE SY-INDEX.
CONSTANTS: opcode_list LIKE th_opcode VALUE 2.
CALL 'ThUsrInfo' ID 'OPCODE' FIELD opcode_list
ID 'TAB' FIELD usr_tabl-sys.
CALL FUNCTION 'TH_USER_INFO'
EXPORTING
    CLIENT = sy-mandt
    USER   = sy-uname
IMPORTING
    TID    = LV_TID.
read table usr_tabl with key tid = lv_tid.
IF sy-subrc = 0.
CASE usr_tabl-type.
    WHEN 2.
      write :/ usr_tabl-type, 'SYSTEM'." (system)
    WHEN 4.
      write :/ usr_tabl-type, 'GUI'." (Gui)
    WHEN 32.
      write :/ usr_tabl-type, 'RFC'."(RFC)

      write :/ usr_tabl-type, 'PLUG-IN'." (Plug-in &).

Dear Abrar
- To see how many scheduling agreement is created for a given period, use VA05, click on [Further sel criteria] and tick the box against [Sales Document type] Now input the scheduling agreement type and execute. You will get list of all scheduling agreements created within the specified period.
- You can see how many line items are created in a sale order for a given period via VA05.

How to get this information for Conky

Hi people,
My question is how to get this information for show in Conky:
- KDE version.
- Last sync (pacman -Sy) and Last update (pacman -Su)
For the first point could be use a script that execute $ kdesu --version and get information from there.
I have no idea how get information from pacman (may be logs?).
Any ideas?
Thank you.

I have had tremendous success with LUA in Conky on Arch. And all you need to to is put the text HI after the "TEXT" line. ^^;
Examples of my LUA usage:

http://kittykatt.silverirc.com/screens/conky-HUD.png
EDIT: Also, I've had success with getting the KDE version by doing the following...
kwin --version | awk '/^Qt/ {data="Qt v" $2};/^KDE/ {data=$2 " (" data ")"};END{print data}'
This is the method I'm currently using in screenFetch. Tested it a couple of times myself, but besides that, I'm not sure if it will work or not.

Hi,
Which website your are using to update the Adobe Flash player? No Adobe website ever ask for any id and password to update the flash player.
If you are using MAC machine and its the password prompt while installing update that you are talking about then please follow What userid & password do I need to install Flash Player?

Interfaces for your own classes - do you bother?

Hi All,
before anyone gets upset, I did post a shorter version this to the Java Prog forum a couple of days ago. I'm reposting here because the thread was pushed down the list just as comments were getting interesting, and I was tossing up which forum was most appropriate anyway...
OK, I'd like to pose a general question on the use of interfaces with your own classes. I am totally behind the concept of using appropriate interfaces for declaration of vars, parameters etc (i.e. use "List" rather than "Vector"), but what about your own classes?
If I have a class in my application that doesn't fit into any kind of framework or class hierarchy, subclass of object basically, should I write an interface with all the same method sigs and use that rather than the class for my vars, params etc? This would make things more flexible in future, enabling you to swap classes in and out of your app more easily.
Taking it a step further, how's this for a design methodology: For every class you write (once again classes that don't fit into your own or somebody else�s hierarchy or framework) do the following
1. Create an interface (MyInterface) that maps 1 to 1 to that class (MyClass), with all the same method sigs.
2. Make the constructor private and manage all the creation of instances of MyClass through a factory that returns objects of type MyInterface.
If you do this there will be no mention of any of your concrete classes anywhere in your app except the factories, making it easier to refactor etc. Do this for all your classes.
A little sketchy but I hope you get idea. Is this complete overkill? Is there a down side to this? Does anyone do anything like this?
Cheers
Matt

Although the pattern you describes adds flexibility, it also adds complexety.
Imagine somebody is looking at your code and from what he sees he deducts that the next thing to look at is the concrete class which is used at a given place.
If you used an interface, he must find out which implementing class is actually used at this place. It's not a big thing, but if every single class has its seperate interface and factory I would consider it overkill ... after all you have to write all the boring code for this.
In the case of doubt I'd agree it's better to throw in an interface and a factory instead of refactoring thousand lines of codes afterwards. But if nothing hints toward a second implementation of the interface, or another reason for using an interface don't bother to write one.
As a general rule I use something like: Don't use a general rule. ;-)

How to create an object of our own class by using Class.forName()??

how to create an object of our own class by using Class.forName()??
plzz anser my qustion soon..

Class.forName does not create an object. It returns a reference to the Class object that describes the metadata for the class in question--what methods and fields it has, etc.
To create an object--regardless of whether it's your class or some other class--you could call newInstance on the Class object returned from Class.forName, BUT only if that class has a no-arg constructor that you want to call.
Class<MyClass> clazz = Class.forName("com.mycompany.MyClass");
MyClass mine = clazz.newInstance();If you want to use a constructor that takes parameters, you'll have to use java.lang.reflect.Constructor.
Google for java reflection tutorial for more details.
BUT reflection is often abused, and often employe when not needed. Why is it that you think you need this?
