How to understand WS has to make use of SOAP

Hi All
via WLS 8.x, we can easily try a HelloWorld java class basis WS and test it
like the following:
String wsdlUrl = "http://localhost:7001/web-services/HelloWorld?WSDL";
HelloWorld service = new HelloWorld_Impl( wsdlUrl );
HelloWorldPort port = service.getHelloWorldPort();
result = port.get( ... );
What I don't understand is, how is the SOAP applied and how can it be kept
track of during the request and response?
Thanks lots
John

HI...
If u want to keep track of soap message u can use handler class (GenericHandler ) which allows you to read and modify or attach attachement.In client code you need to specify this handler then it ll call request and reponse method of handler berfore n after calling webservice.

How to understand if olap cache is used

Hi,
I am trying to understand if my query uses the olap cache or not.
First I executed the report with specific selections. After that, I executed the report again with the same selections but it took almost same time to bring the report output. There are lots of exception aggregates in my query, so i wonder if olap cache will help me or not.
So, how can I understand if the query uses the olap cache or not ? (i am using RSRT screen, with 'do not use cache' blank)
Thanks
Ozan

Hi
Check in tcode RSRT. Input your query tech name and from the properties tab, you can see if the olap cache is set to be used in the cache mode field.
You can check if the entries you are making in the cache are used, if you, also from RSRT, go to cache monitor->main memory and expand the folder "query directory".
now search for your query tech name.
a folder will appear with your query tech name if the cache mode enabled.
right-click and choose details. here you will see "read accesses" and the number will tell you how many times this entry has been read.

How to design class hierarchy to make use of Bimorphic inlining

I have a question regarding the optimum number of implementations you can have of an interface.
I have 1 interface and 2 main implementations. All the methods except one very rarely invoked method in those two main sub-classes are frozen using final.
interface Foo{
void hotMethod1();
void rarelyUsedMethod();
class A implements Foo{
final void hotMethod1(){.. .. ..}
//Non final!!
void rarelyUsedMethod(){.. .. ..}
class B implements Foo{
final void hotMethod1(){.. .. ..}
//Non final!!
void rarelyUsedMethod(){.. .. ..}
}Then there are many (more than 20!) sub-classes of these 2 main sub-classes - dynamically generated bytecode.
class Aee26671 extends A{
void rarelyUsedMethod(){.. .. ..}
class B33423 extends B{
void rarelyUsedMethod(){.. .. ..}
class C12ds423 extends A{
void rarelyUsedMethod(){.. .. ..}
and so on...All these second level sub-classes just override the rarelyUsedMethod().If in some caller method I do this:
x(Foo foo){
foo.hotMethod1();
}Does the Hotspot compiler recognize that there are only 2 possible targets because A and B have their implementations marked as final?
I've heard of Bimorphic inlining. But does it look just at candidate Sub-classes - in this case there are more than 2 sub-classes.
Or, does it realize that the actual candidate implementations of the hot method are just 2 (A and B) because they are "final" and optimize it?
PS: Does Hotspot do Bi or Polymorphic inlining?

Hi Ashwin,
as far as I understand, the bi-morphic case is really a special optimization that occurs when there are only two possible classes (not necessarily methods) involved. You can easily test that by adapting my newsletter: [Polymorphism Performance Mysteries Explained|http://www.javaspecialists.eu/archive/Issue158.html]
Here is how I tested it:
import java.util.Random;
public class PolymorphismTest {
private static final int UPTO = 100 * 1000 * 1000;
public static void main(String[] args) throws Exception {
    int offset = Integer.parseInt(args[0]);
    Foo[] tests = generateTestData(offset);
    System.out.println("Warmup");
    test_all(tests);
    System.out.println("Actual run");
    printHeader(tests);
    test_all(tests);
private static void test_all(Foo[] tests) {
    for (int j = 0; j < 10; j++) {
      run_tests(tests);
public static void run_tests(Foo[] tests) {
    long time = System.currentTimeMillis();
    test(tests);
    time = System.currentTimeMillis() - time;
    System.out.print(time + "\t");
    System.out.flush();
    System.out.println();
public static void test(Foo[] sources) {
    Foo t0 = makeRandomTest(sources);
    Foo t1 = makeRandomTest(sources);
    Foo t2 = makeRandomTest(sources);
    Foo t3 = makeRandomTest(sources);
    Foo t4 = makeRandomTest(sources);
    Foo t5 = makeRandomTest(sources);
    Foo t6 = makeRandomTest(sources);
    Foo t7 = makeRandomTest(sources);
    Foo t8 = makeRandomTest(sources);
    Foo t9 = makeRandomTest(sources);
    for (int i = 0; i < UPTO / 10; i++) {
      t0.hotMethod1();
      t1.hotMethod1();
      t2.hotMethod1();
      t3.hotMethod1();
      t4.hotMethod1();
      t5.hotMethod1();
      t6.hotMethod1();
      t7.hotMethod1();
      t8.hotMethod1();
      t9.hotMethod1();
private static Foo makeRandomTest(Foo[] sources) {
    return sources[((int) (Math.random() * sources.length))];
private static void printHeader(Foo[] tests) {
    System.out.print(tests[0].getClass().getSimpleName());
    System.out.print('\t');
    System.out.println();
private static Foo[] generateTestData(int offset)
      throws Exception {
    switch (offset) {
      default:
        throw new IllegalArgumentException("offset:" + offset);
      case 0:
        return fillSources(A.class);
      case 1:
        return fillSources(A.class, B.class);
      case 2:
        return fillSources(A.class, B.class, Aee26671.class);
      case 3:
        return fillSources(A.class, B.class, Aee26671.class, B33423.class);
private static Foo[] fillSources(
      Class<? extends Foo>... fooClasses)
      throws Exception {
    Foo[] sources = new Foo[1000];
    Random rand = new Random(0);
    for (int i = 0; i < sources.length; i++) {
      int offset = Math.abs(rand.nextInt() % fooClasses.length);
      sources[i] = fooClasses[offset].newInstance();
    return sources;
}On my machine, the results are as follows:
1 class: average=0, stdev=0
2 classes: average=103, stdev=4
3 classes: average=672, stdev=26
4 classes: average=666, stdev=0.4
As I thought, the bi-morphic optimization is only applied on a class instance basis, rather than a method basis.

How to understand which BC set for Object BUS 2121 has to be used.

hi,
How do we understand this,
If i have a BO BUS 2121 - then how do i know which BC set has to be used. and wht would be the suitable BC Set for my reuirement .
On what basis would i come to know that what would be the prefered BC set for this.
Kindly suggest me with some solution or suggestion
Thanks,
shankar

Hi,
BCSet is just sample configurations for your quick system setup. You can learn process level definition setting from sample BSSet configuration and copy/enhance it for customer scenario.
For BUS2121, there are 3 BCSet are available.

How can I make a intro page for my website, then after the intro has run make the page automatically change to my we site home screen

how can I make a intro page for my website, then after the intro has run make the page automatically change to my website's home screen

You can do this using a meta refresh but the problem is you have to add it to the html file for the page very time you publish changes.
A better way is to create a splash page and upload it to the server outside of the folder produced by iWeb. Example HERE.
The meta refresh is added to the head section of the html file...
<meta http-equiv="refresh" content="32;url=http://www.domain.about.com/Page-Name.html">
The delay time in seconds is marked in blue and the URL to the redirect page is in red.

How to make use of adjacent data elements within the same buffer

Hi,
         Does anyone know how to make use of adjacent data elements within the same buffer? To make my question clearly, I would like to give you an example. In my application, I set "sample to read" as 10 which means at each loop 10 data samples will be taken into a buffer. Now, what I would like to do is to do some calculations on adjacent data samples in same buffer. I tried to use "shift register" for this, but it seemed to me that it only can deal with the calculation between data from adjacent loops. In other words, it skips 9 data elements and take the 10th one for the calculation.
         Here I also attach my VI showing what I did.
    Thank you very much in advance,
                        Suksun

Hi Suksun,
      I hope you'll forgive me for distilling your code - mainly to understand it better. I tried to duplicate your logic exactly - which required reversing the "derivatives"-array before concatination with the current samples array. As in your code, the last velocity is being paired with the first position. If first velocity is really supposed to be paired with first position, just remove the "Reverse 1D Array" node.
cheers

How can you keep your iPhone 4 (using it as my car's iPod) staying on the Audible app? When I leave the car and return to continue hearing a book, it has switched to iTunes.

How can you keep your iPhone 4 (using it as my car's iPod) staying on the Audible app? When I leave the car and return to continue hearing a book, it has switched to iTunes.

The first time an iPhone is connected to iTunes that is used to sync with another iPhone or iOS device, you are prompted to transfer the backup for the other iPhone or iOS device or to set up the iPhone as a new iPhone.
The former does as provided - it transfers the backup for the other iPhone or iOS device to the iPhone replacing all data on the iPhone that is included with the backup being transferred. The latter does nothing allowing you to make your various selections for the iPhone sync preferences with iTunes.
This is designed to be done right away with a new iPhone.
If you don't have a backup for the iPhone with iTunes on your computer and don't have an iCloud backup that hasn't been updated since choosing to transfer the backup for your iPod Touch to the iPhone, the data that was on the iPhone is gone.

Hi Raj
Function Modules
Function modules are procedures that are defined in special ABAP programs only, so-called function groups, but can be called from all ABAP programs. Function groups act as containers for function modules that logically belong together. You create function groups and function modules in the ABAP Workbench using the Function Builder.
Function modules allow you to encapsulate and reuse global functions in the SAP System. They are managed in a central function library. The SAP System contains several predefined functions modules that can be called from any ABAP program. Function modules also play an important role during updating and in interaction between different SAP systems, or between SAP systems and remote systems through remote communications.
Unlike subroutines, you do not define function modules in the source code of your program. Instead, you use the Function Builder. The actual ABAP interface definition remains hidden from the programmer. You can define the input parameters of a function module as optional. You can also assign default values to them. Function modules also support exception handling. This allows you to catch certain errors while the function module is running. You can test function modules without having to include them in a program using the Function Builder.
The Function Builder also has a release process for function modules. This ensures that incompatible changes cannot be made to any function modules that have already been released. This applies particularly to the interface. Programs that use a released function module will not cease to work if the function module is changed.
Check this link
http://help.sap.com/saphelp_nw2004s/helpdata/en/9f/db988735c111d1829f0000e829fbfe/content.htm
You can execute function module in SE37ie you can perform the activiites defined in the function module by executing it.
By deleting BOM you mention the FM name in se37 and execute. In some function module it will ask input parameters as developed in the program , you have to give the input parameters and execute.

How to make use of the 'Groups' in Screen Layout?

Hi All,
I have a screen with 10 input fields (F1, F2, .. F10).
I set the 'Groups' attribute in the screen layout to 'DIS'.
How could I make use of this 'Groups' attribute so that when I loop the screen, I will only disable fields with the 'Groups' attribute set to 'DIS'? Thanks
I tried the following codes, but it's not working:
LOOP AT SCREEN.
    IF SCREEN-GROUPS IS NOT 'DIS'.
      SCREEN-INPUT = '1'.
      MODIFY SCREEN.
    ENDIF.
ENDLOOP.
It says ==> The data object 'SCREEN' does not have a component called 'GROUPS'.

In the Attributes of a screen field, there is an attribute called "Groups". This has 4 options for input (4 text boxes)
SCREEN has 4 fields GROUP1, GROUP2, GROUP3 and GROUP4.
The first text box under Groups attribute corresponds to SCREEN-GROUP1,
2nd text box for SCREEN-GROUP2
3rd text box for SCREEN-GROUP3
4th text box for SCREEN-GROUP4
Hope this helps.
Thanks,
Balaji

How to make use of 'Icon Name' in Logical link?

I see the option 'Icon name' in 'define logical links' in SPRO. It does not however has an F4. I tried giving the name of image in the relevant skin. But no image appears besides the logical link. Is there something else that needs to be done to get an image besides workcenter link? How to make use of this 'Icon Name' in logical link?

Hi,
i guess this icon_name is not possible for every skin in CRM70.
We use nova skin - here it is not possible.
With default skin i saw icons for example on the salespro startpage.

How to make use of Re Usable Objects

Hi all,
I have created an application in Oracle Apex 3.2, and running fine. I want to include ReUsable Objects functionality in my application.
Our requirement is,
"Common Objects(eg LOVS,Validation,etc) should be written as common objects adn held in a "master" application that all applications refer through the SUBSCRIBE function. All common objects should NOT be copied into an application but subscribed from master application."
1) What does this "master" application mean?
2) How can we make use of subscribe function? and where can i find this subscribe function?
Can somebody help me in this regard by illustrating an example??
Thanks & Regards,
Sunil Bhatia

Here's an example.
I create a new application in APEX called Master with Application ID = 100. I modify some templates, create some LOV's in this master template.
I create a 2nd application in APEX called Subscriber with Application ID = 101.
In 101 I go to Shared Components => List of Values => Create. Choose to create as a copy of an existing list of values. In the dropdown, I choose Master (100) and click Next. You then are presented with all of the LOV's from your master application. First off you want to change the name from Copy of <LOV> to just <LOV> more because it is kind of confusing if you don't. In the copy drop-down, this where you choose Copy and Subscribe.
The way it works is that once an object subscribes, you always make changes to that object in Master (100), and there is a button to push that change to all subscribing applications. So if you have 30 applications subscribing to that one LOV, you just make the change once, push it to the subscribers and they are now up to date.
Keep in mind it doesn't work with all objects and only certain objects may be subscribed to. Objects like Application Processes for instance do not have a subscription feature, but you could use packages to keep common logic and just reference the same package anywhere you need it.
What I ended up doing was to create a master and a subscription application. The subscription template has no actual pages, just subscriptions to templates and LOV's that I need. Whenever I need a new application, I just create a new application as a copy of that subscription application and my subscriptions are already setup for me.
Check out the documentation and just search for Subscribe or Subscription and it should explain pretty much what I did above.

I'm a little confused
Is the problem
1 - You want to Access a table in an existing 9i database from a different 10g database

You can reuse the packages in /var/cache/pacman/pkg/ on your Arch32.
You can use these saved packages in a 32bit chroot ENV on your Arch64. Just pacman -U all of them.
