How to study CORBA

Hi,
I only have some basic java programming knowledge. I am working on a CORBA based project now. Our company bought a system which has a loads of object models for CORBA interfaces and associated technical documents. These documents don't make any sense to me because I have no CORBA experience before at all.
I browsed www.omg.org and download some CORBA specifications. Thousand pages to read.
I want to finish this project as soon as possible, anyone can give me some idea how to study CORBA quickly?
Anybody can describe the learning curve and give me some key words for searching and studying?

How to start java card development?

Good Evening all,
I am novice for java card development , from last some days I study java card and terms related to it, now i have some knowledge about applets , and API. as i read about java card 2 and 3, I think i moved to java card 2 that's why i download jcdk 2.1.
Now i want to do something in development rather than further conceptual study. Frankly speaking I m confused where to move because different sites have different point of view so i want to execute my knowledge which i earned from last some days...
so I want to ask
1- which IDE would be best for java card development? { eclipse or net beans or something other}
2- what things i would be require during java card application?{ java sdk version? jcdk version? ocf? or what}
3- at start i want to use simulation technique to test what i made and how its work, so for this which tool or IDE would be best work for me,
so kindly request you to guide me and show me the path where i can move and achieve what i want..
---------------------------------------------------------------------------------------------------Thank you in advance------------------------------------------

Hello umer,
last night it seems very tough to execute sample program of jcdk 2.2 but finally i make it, and i also i got the IDE - net beans that is very good for java card...
I think i should share my knowledge here for next novice people...
----------------------------------------------------------------------------java card development require-------------------------------------------------------------
Because here we use java for java card so we require
1- java development kit (JDK) - use below link to get this.
[get jdk here|http://download.oracle.com/otn-pub/java/jdk/6u30-b12/jdk-6u30-windows-i586.exe]
2- Java card require java card development kit (JCDK) I think java card version 3 is latest but i used jcdk 2.2.1
[get jcdk here|http://download.oracle.com/otn-pub/java/java_card_kit/2.2_01/java_card_kit-2_2_01-win-gl.zip]
now i think this is enough to start java card development...
follow below steps
1- install jdk 6 in c:/java/jdk1.6
2-keep jcdk in c:/java_card_kit-2_2
3- open command prompt and run
a)-set JC_HOME=c:\java_card_kit-2_2
b)-set JAVA_HOME=c:\java/jdk1.6
c)-set PATH=%JC_HOME%\bin;%PATH%
4-there are some sample project in scdk, if you want to get confidence , u should run one of them..
run command- jcwde jcwde.app { jcwde is a simulator where u check what u made }
and run this command in another command prompt- apdutool -nobanner -noatr demo1.scr > demo1.scr.jcwde.out
You can get detail of 3 and 4 step from cJDK_Users_Guide.pdf which is present in jcdk.
------------------------this is all which u need to do to get confidence in java card, but dont be over confident because in reality "the ball is not in your court yet"
Note- if you are searching which java IDE is best for java card development then
[click here- this is one of the best ide for java card|http://dlc.sun.com.edgesuite.net/netbeans/7.1/final/bundles/netbeans-7.1-ml-windows.exe]

How to configure JAVA webdynpro in ECC 5.0??

Hello Friends,
I just installed ECC 5.0. Is java webdynpro already installed with ECC 5.0?? If not how to install it?? if yes how to configure it?? And how to run java webdynpro?? help me please
Thanks

No, not required.
You will need to maintain JCo destinations when you deal with your backend R/3 system from WD but as of now you don't need to configure anything.
Just install and start creating your project in WD Java.
Happy Learning

Thanks you very much.

It is unclear where you are having a problem. Is your issue at runtime (when the form runs in the browser) or when working in the Builder on the form?
Also be aware that you will need to sign your jar and include some new manifest entries. Refer to the Java 7u51 documentation and blogs that discuss the changes.

How to use java programe in oracle form

Hello Expert,
My Config is : -
Forms [32 Bit] Version 11.1.1.3.0 (Production)
Jdeveloper - 10.1.3
I want to use the java programe in form builder. I create the one java class in Jdeveloper -
package demo;
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
public class get_info{
   public static void main(String[] args){
   ch_add();
   public static void ch_add()
InetAddress ip;
try {
ip = InetAddress.getLocalHost();
/*System.out.println("Current IP address : " + ip.getHostAddress()); */
NetworkInterface network = NetworkInterface.getByInetAddress(ip);
byte[] mac = network.getHardwareAddress();
/*System.out.print("Current MAC address : ");   */
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++)
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
System.out.println(sb.toString());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (SocketException e){
e.printStackTrace();
and this into Formweb.cfg and default.env and also add into Form_class_path. After that i import this java into forms.

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

we followed the README.txt instructions, and stop/start weblogic service before/after apply patch. Can anyone suggest a solution or Doc ID for helping us?
thank you very much!

Solutions: Bounce the applications and check the arguments if you can increase it. It is due to memory issue
You can set these values in CommEnv.sh (.cmd for windows) file located in the weblogic_home/common/bin directory.
This gets applied to all the domains under that wls home.
If you want to make the changes to specific domain then edit the SetDomainEnv.sh file located under the domain/bin directory.
