SAP NetWeaver Composition Environment - Java/J2EE Development

Hi all
   I am very new to this forum.
   Just want to know whether <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/40fe9a6a-2765-2a10-dba9-fc721621e55d">SAP NetWeaver Composition Environment</a> can be used for normal SAP Java/J2EE Development ?
Also does this Environment has J2EE Engine ?
I am not worried about presence of NWDI in this Environment ! But please let me whether it is avaiable or not ?
Any help will really appreciated !
Thanks all !

HT5559 I've followed the instructions to re-enable apple supplied Java SE 6 but this does not work. Java is still disabled and I'm having problems with dependant applications.

I've followed the instructions to re-enable apple supplied Java SE 6 following upgrade to version 7 which caused a number of applications to stop working.
I wondered if anyone has had any joy re-enabling JAVA SE 6. I've tried contacting Apple but cannot get any response. They've sent me back default messages claiming that they have tried to contact me - they haven't! I'd be grateful for some help with this. Thanks

This is the latest news about Java.

I do not use Java. So I cannot verify that this is the solution or not..

How does this Linked List work?

Hi.
I wonder how this linked list work
import java.util.Scanner;
public class LinkedList {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        Elem front = null;    // First element of list.
        Elem back = null;    // Last element of list.
        while (in.hasNext()) {
            String word = in.next();
            Elem e = new Elem();     // Create a new list element.
            e.data = word;           // Set the data field.
            if (front == null) {
                front = e;            // Back element will be set below.
            } else {
                back.next = e;       // Link last elem to new element.
            back = e;
        System.out.println("*** Print words in order of entry");
        Elem curr = front;
        while (curr != null) {
            System.out.println(curr.data);
            curr = curr.next;
class Elem {
    public Elem next;    // Link to next element in the list.
    public String data; // Reference to the data.
}Does anyone know how this allocates memory?
I feel strange because it's just front = e
and back = e
but it never says anything like front.next = back or something..
Can anyone help me on this?

Does anyone know how this allocates memory?Memory is allocated on this line:            Elem e = new Elem();     // Create a new list element.
I feel strange because it's just front = e
and back = e
but it never says anything like front.next = back or something..Well, it doesn't need to. Setting .next is taken care of after the initial element is added. It never explicitly says front.next = back because front.next is set when the second element is added. It's set implicitly, on this line:                back.next = e;       // Link last elem to new element.It's implicit in that at that point front and back point to the same element.

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]

HT5559 JAVA WITH CHROME!!! I am trying to login to my bank account at nordea.dk. This website uses somekind of java thing. Chrome cant't load it. Works perfect with Safari. How to make it work in Chrome?

I am trying to login to my bank account at nordea.dk. This website uses somekind of java thing. Chrome cant't load it. Works perfect with Safari. How to make it work in Chrome?

Do you speak of true blue Java or Javascript? If the latter then it is a problem with the Browser.
But if it is the real Java, do you have the offical version of Java from Oracle installed?
Getting applications to see official Java is a nightmare. If you install the Runtime Environment only (JavaRTE) most applications do not see it.
To force offical Java system wide, I found you have to install the Java Developer Kit (JavaJDK). It's a larger install as it also comes with documentation and compilers but it make offical Java system wide.

Applets not working with Java 1.7.0_51 in MII 14.0 SP4 Patch 5

Hi,
I'm currently evaluating the migration of our MII 12.0 developments to MII 14.
But I'm running in several issues just trying to use simple things like a SQL query template with an iGrid Display template in test mode.
Used versions are: MII 14.0 SP4 Patch 5 and on client side the latest Mozilla Firefox with Java 1.7.0_51
At first I always get a java security warning when the applet is being loaded about unsigned applications.
At second the applet itself is not running. It always shows "No data available" and the java console shows the following errors (iResult is the id of the applet):
iResult [ERROR] - Couldn't set query template: No Query Defined
iResult [ERROR] - Couldn't set display template: null
iResult [ERROR] - Couldn't set display template: null
Is this perhaps a general problem, that the MII applets are not working with Java 1.7.x versions?
If I call the same MII page from a client with Java 1.6.x it is working without errors.
Do you have some suggestions for me?
Regards Timo

please clear your JAVA Cache. that should solve the JRE issue. thanks

I need help getting this program to work.

K. I don't pay much attention in my AP Comp Science Class.. but my teacher said if i can get this program to work i get an a for the semester... The program is Metrowerks Codewarrior IDE.. we are running it on windows 98 i think. She said she can't get it to compile.. so i guess it just needs to be able to input simple java programs (i.e. loops, just the regular crap) and compile them and run them...i have no clue what is wrong with it.. it could just need a patch...or we may just be going about it the wrong way...any help would be SUPER appreciated...

BAPI not working in Java Webdynpro

Hi,
My BAPI from SAP is working in Netweaver perfectly, but when I call the same with the equal parameters in Java webdynpro, no results.
I'm using following function: 'CVAPI_DOC_VIEW'.
Any idea why the BAPI is not working in Java Webdynpro?
Regards,
Tim

Hi Tim,
AFAIK 'CVAPI_DOC_VIEW' will work only in standard SAP Dynpro. Inside Webdynpro it is forbidden to save files in the background and using GUI class with execute, so you cannot use that Standard FM.
Check this thread .
Thanks

How SDA and DDA works in Java Card?

Hi Friends,
I want to know how exactly SDA and DDA works in Java Card technology..
Yes, i know that SDA (Static Data Authentication) is valid for every transactions, but the key used is always same for every transaction made..
and DDA (Dynamic Data Authentication) uses dynamic key for every transactions, it means that one key is valid for one transaction..
But, i'm a little bit confused how this is implemented in Java Card..
Is it related with SCP01 and SCP02?..
Please help me regarding this..
Thanks in advance

Hi,
I want to know how exactly SDA and DDA works in Java Card technology..This is an EMV concept and as such is not implemented in Java Card as such. You would have to create an implementation to be able to use SDA and DDA.
But, i'm a little bit confused how this is implemented in Java Card..
Is it related with SCP01 and SCP02?..It is not implemented natively in Java Card and are not related to SCP. SDA and DDA are for the EMV card application (card application data updates) and SCP is for the card manager (card content updates). While they could be considered similar concepts, they are not related in a Java Card sense.
Cheers,
Shane

Jar doesn't work while java work fine

I have a similar but not same case as "Please Help, jar file don't work" that is on 4/20. My program works fine by java class execution, but when I put them to jar it generates NullPointerException. The program get data from separate csv files. The error I get by executing jar is quite same as when I delete csv files and execute java. Only one jar file involves. csv files are in the same directory as class files.
- My manifest file is;
Manifest-Version: 1.0
Class-Path: .
Main-Class: MetricConverter
Created-By: 1.4.2_07 (Sun Microsystems Inc.)
I tried different Class-path possibility, but same result.
java.lang.NullPointerException

When I delete csv files from the directory and execute java, the following line is added to 1st line of above Exception message.

The following is chartMaker method;

while(a2<gotChart[a1].length){
a2++;
a1++;
index=i;
chart[index]=new String[a1][a2];
chart[index]=gotChart;
I have looked every place I can imagine for a day, but found no answer. Since it works fine with java it should be with jar archiving.
Any advice will be appreciated.
Thanks.

atmguy, thanks for sticking with this.
I spend a half day again studying this.
A new founding that is jar is getting csv files from outside of jar archive.
My command to make jar is "jar cvfm MetricConverter.jar mym *.class si.au source"
source folder has 4 csv files. and result is,
added manifest
adding: MenueMaker$1.class(in = 809) (out= 515)(deflated 36%)
adding: MenueMaker$2.class(in = 699) (out= 472)(deflated 32%)
adding: MenueMaker$3.class(in = 589) (out= 398)(deflated 32%)
adding: MenueMaker$4.class(in = 1714) (out= 950)(deflated 44%)
adding: MenueMaker$5.class(in = 667) (out= 436)(deflated 34%)
adding: MenueMaker.class(in = 5168) (out= 2824)(deflated 45%)
adding: MetricConverter$1.class(in = 349) (out= 247)(deflated 29%)
adding: MetricConverter.class(in = 1068) (out= 677)(deflated 36%)
adding: ReadCSV.class(in = 1459) (out= 913)(deflated 37%)
adding: s1.au(in = 55708) (out= 44941)(deflated 19%)
adding: source/(in = 0) (out= 0)(stored 0%)
adding: source/csv0.csv(in = 543) (out= 254)(deflated 53%)
adding: source/csv1.csv(in = 765) (out= 365)(deflated 52%)
adding: source/csv2.csv(in = 340) (out= 191)(deflated 43%)
adding: source/csv3.csv(in = 1004) (out= 497)(deflated 50%)
Double Clicking MetricConverter.jar with the source folder in the same directory open the program even copying them to other directories. However, from desk top or my document doesn't work (seems to me space in the directory name?). Without source folder console shows NullPointerException at ReadCSV.. The program cannot find csv files.
Another thing that is the program only works when manifest file has class-path : . and <cade> URL pickURL=getClass().getResource("./source/csv"+i+".csv");
has ./.
I tried making source.jar and putting index using "jar -i MetricConverter.jar" with "class-path: source.jar" in manifest, and use jnlp, but nothing works.
You seems to me an experienced java programer. If you don't mind look this at www.mixvision.net/java/MetricConverter.jnlp, also I leave www.mixvision.net/java accessible for now.
Thanks again.

SGD4.6 can't work with Java update7.51

SGD4.6 can't work with Java latest version update 7.51. The webtop keeps showing "loading", is there any patch for this issue?
When Java released update 7.21, it also can't work with SGD4.6, then Oracle fixed it by updating a patch, so how about this problem?

Have a look at this Thread:
https://community.oracle.com/thread/2614978

Timer works with Java 1.4 and not Java 1.3 - Why?!

I am totally lost. I can run this bit of code in java 1.3 and all works fine...
     ActionListener alarmtask = new ActionListener(){
           public void actionPerformed(ActionEvent event){
              decrementClock();
              setDisplay();
        alarm = new Timer(1000, alarmtask);Then later...
        alarm.start();But when I run it using Java 1.4 it does nothing. The decrementClock() method is never called. I have checked if alarm.isRunning(); and it is.... it seems that the actionPerformed() message never gets to alarmtask.
Please help!
Thanks
LT

I don't know whether this helps, but:
The Installer copies the java.exe and javaw.exe files into c:\{windows\winnt}\system32 which is on the path variable by default. These files are copied from the JRE, not the SDK.
Try use:
...\> java[w] -showversion your.Classto ensure it's actually the intended version.
It's hard to believe yet that this is the problem... another idea: is it possible that you change CLASSPATH along with this, such that it points to an outdated version of your implementation?

Confused as to why this doesn't work...

I wrote this code correctly, but it doesn't seem to work. I'm not sure if I'm leaving something out or not using something correctly. If anyone can tell me why this doesn't work, it would be greatly appreciated!
P.S. in the actionPerformed method, I want to put the window to close once someone clicks an "ok" button. How is this done? I've tried using setDefaultCloseOperation(3), but it doesn't seem to work.
peace,

Oh see, you said this:
"P.S. in the actionPerformed method, I want to put the window to close once someone clicks an "ok" button. How is this done? I've tried using setDefaultCloseOperation(3), but it doesn't seem to work."
so I said this:
"setVisible(false)"
NOOOOOOOOOOOW you say the TextArea doesn't show up...that's a whole other problem.
Jeeeeeeeeeeeeeeeez.
So what layout manager are you using in the container? (hint hint)
