How I build my own libraries of classes/methods in java ?

How I build my own libraries of classes/methods in java ? how then I refer a functionX() (i mean method) in LibraryX ? can you give a short/brief example of a library with a class with a method and a main method of normal class calling this method (of external's added library's) ?

Just another cross poster.

How to pass importing parameter of super class method to subclass method?

hi all,
i have defined a class
CLASS CUST_REPORT DEFINITION.
PUBLIC SECTION.
    METHODS:DATA_RETRIVE IMPORTING CUSTID_LOW TYPE ZCUSTOMER-ZCUSTID
                                   CUSTID_HIGH TYPE ZCUSTOMER-ZCUSTID.
    DATA:IT_CUST TYPE TABLE OF ZCUSTOMER,
         WA_CUST TYPE ZCUSTOMER.
ENDCLASS.                    "cust_report DEFINITION
The method DATA_RETRIVE   in this class has two importing parameters named CUSTID_LOW   and CUSTID_HIGH.
then i have defined subclas of this clas.
LASS CUST_ORD DEFINITION INHERITING FROM CUST_REPORT.
PUBLIC SECTION.
    DATA:IT_ORD TYPE TABLE OF ZORDER.
    METHODS:DATA_RETRIVE REDEFINITION,
           DISPLAY.
ENDCLASS.                    "cust_ord DEFINITION
Method DATA_RETRIVE   is redefined.
So how to pass importing parameteres of super class method to sub class method with the same name.
Thanks and Regards,
Arpita

Hi,
I tried like this.
METHOD DATA_RETRIVE.
CALL METHOD SUPER->DATA_RETRIVE
      EXPORTING
        CUSTID_LOW = I_CUSTLOW
        CUSTID_HIGH = I_CUSTHIGH.
ENDMETHOD.
But parameters I_CUSTLOW and I_CUSTHIGH are not getting values after call to method.
Thanks and Regards,
Arpita

How to build my own SOAP envelope

Hi
after a lot of work I have now realised that my SOAP to SOAP scenario can't use SAP XI std SOAP ENVELOPE on the receiver part.
How to I build my own SOAP ENV in my RECEIVER payload? iMaybe in the mapping or in the WSDL/XSD?
Any guides or experienses are welcome
hope someone can help
cheers

Hi Bowie,
Here is one possible approach...
1) Set "Do Not Use SOAP Envelope" in your Receiver SOAP Adapter.
2) Add this xsl as a second step in your interface mapping.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
    <env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
      <env:Body>
        <xsl:copy>
          <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
      </env:Body>
    </env:Envelope>
</xsl:template>
<xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>
</xsl:stylesheet>
You can then modify the soap envelope nodes above to create what you need.

How to build your own install img?

How do I build my own arch install image...iirc there are tools but I don't know how to use them.
Also is it possible to use the usb .img installer off of one's harddrive? I know I can use dd to put it on a partition, but was wondering if it would be able to boot and install properly.

This is from an email by Dieter to the arch-releng list:
git clone http://projects.archlinux.org/git/archiso.git
cd archiso/archiso
sudo make install #to be packaged later
cd ../configs/install-iso
# change version in Makefile
# if on x86_64, remove intel-536ep and intel-537 from packages.list
./buildall.sh
scp release/* ...somewhere...

How to build my own LEXER

Hi :
I want to build a Text Query Application which bases on Oracle interMedia Text. Besides some default languages the interMedia supports (English, French ...), I need index on my own language document. When I refered to the Oracle Text Reference, I saw that I can use the BASIC_LEXER for English and all other supported whitespace delimited languages. My language is Vietnamese which has whitespace delimiter. The question is that can I build my own language dictionary-lexer (similar to some default dictionaries : English, France, German, Chinese ...) to index my document and how can I do that ? In the documents I refered (Oracle Text Application Developer's Guide and Oracle Text Reference) I could'n find direction for doing this.
Thanks.

Hi,
In 9.2 there is a new feature: USER_LEXER. The USER_LEXER lets you write and plug in your own lexer to handle
languages or other indexing techniques that Oracle Text does not support. We will be publishing the 9.2 Text technical
overview in a few days that shows you how to do it.

How to build my own SELECT-OPTIONS?

Hi experts,
I hv 4 values like for a field, (say VBAK-BNAME),
NAME_A
NAME_D
NAME_M
NAME_Z
My selection- screen is like,
SELECT-OPTIONS: MANAGER FOR VBAK-BNAME.
So,
1) How to build the SELECT-OPTIONS table in my ABAP code?
I mean, if the user enters the NAME_A TO NAME_Z in select-options, the system shuld take in-between NAMEs also!
(Actually, I thiught that, the SAP will take care of building the select-options table based on Alphabetical Order, but, When I observed in debug mode, its not like that!)
2) And Where I hv to write the code for building select-options? I mean, Is it DATA DECLARATION part, AT SELECTION SCREEN or AT SELECTION SCREEN OUTPUT or START OF SELECTION?
thanq.

Hi,
Pls. suggest me other than RANGES?
Well, if you don't want to use RANGE then you can do it at SELECT statement.
SELECT BNAME
INTO TABLE ITAB
FROM VBAK
WHERE BNAME IN ( NAME_A, NAME_D, NAME_M, NAME_Z )
OR
SELECT BNAME
INTO TABLE ITAB
FROM VBAK
WHERE BNAME BETWEEN 'NAME_A' AND 'NAME_Z'.
2) under which event i hv to write it?
If you are using in SELECT statement, then you use at START-OF-SELECTION.
If you are buiding RANGE, then you can use at any events such as INITIALIZATION, AT SELECTION-SCREEN OUTPUT, START-OF-SELECTION, etc.

How to build my own policy?

i need build my own policy to interact with database.
just tell me where can i get a better reference of this.
thanks a lot

http://www-106.ibm.com/developerworks/library/j-jaas/?n-j-442
This example from IBM is very good however it does more than you may need. Concentrate on the XMLPolicy.java code and corresponding .xml files.
hope this helps!

How to keep track of all the classes/methods/properties created in a long script

Hi,
I'm curious to know what method people use to keep track of all the classes, methods, and properties you've created when writing a longer script.
For quick scripts, this isn't a problem. But for long scripts it can get quite difficult to keep track of all the objects one has created, and all their methods and properties, and overloaded constructors, etc.
ESTK is great, and it's the IDE I use for InDesign scripting, if only because of it's powerful debugging options.
But it doesn't provide any way of keeping track of this stuff. No proper Intellisense as in Visual Studio.
I'd be interested to hear how people solve this issue.

Hi Ariel,
Not sure it is relevant to your question but I have an old snippet that collects and displays ExtendScript references using $.list(). This may help to track some object relationships.

How to recognize the name of invoked classes&methods&fields in a class

I am now doing some programming used to recognize the name of all classes, methods, constructors and fields invoked from other classes in a given class. This recognition is required automatical. Now I really have no idea how to realize it. Can anyone please give me some suggestions how to programme it?
Now I show you a specific example to make sure you understand my question.
From the following example, firstly I've no idea what outer classes, methods and fields are used in class "PointShadowProtocol". However, the expected functionality of realization is to find out: 1, the name of two used outer classes: Shadow, Point; 2, invoked constructor: Shadow s=new Shadow(int x,int y); 3, invoked methods: Point.getX()， Point.getY()， Point.printPosition()，Shadow.offset，Shadow.printPosition(); and 4, invoked field: Point.x,Point.y,Shadow.x,Shadow.y
public class PointShadowProtocol{
private int shadowCount=0;
public static Shadow getShadow(Point p){
Shadow s=new Shadow(p.x,p.y);
return s;
public void setting(Point p){
Shadow s=new Shadow(p.x,p.y);
shadowCount++;
public void settingX(Point p){
Shadow s=getShadow(p);
s.x=p.getX()+Shadow.offset;
p.printPosition();
s.printPosition();
public void settingY(Point p){
Shadow s=getShadow(p);
s.y=p.getY()+Shadow.offset;
p.printPosition();
s.printPosition();
Actually, after realizing this functionality, I will use these results to automatically generate the related class stub, method stub, field stub, which can be used to test the given class "PointShadowProtocol", probably equivalent to unit test.
Any suggestions are welcome. Thank you in advance for your reply.

Using BCEL sounds a good idea for a class in Java. Actually, I want to target an aspect, which is from AspectJ, without knowing any invoked classes, class methods and fields inside an aspect in the first place (examples of an aspect is as showed below). An aspect in AspectJ is just like a class in Java. But an aspect can't be compiled if the invoked outer classes and methods don't exist. (In fact, the weaving of an aspect into classes happens in the compile time, an aspect can't be compiled if the woven classes (or invoked classes) don't exist, which means I have to find out the all the invoked classes, class methods and fields in that aspect before the compile time) So BCEL could not apply into an aspect in AspectJ.
I am sorry to introduce new concepts here. However,the solution to find out all the invoked outer classes, class methods and fields in a given class before the compile time can be applied to an aspect as well.
Thank you for your time to think about my question.
public aspect PointShadowProtocolAspect {
     private int shadowCount=0;
     public static Shadow getShadow(Point p){
          Shadow s=new Shadow(p.x,p.y);
          return s;
     pointcut setting(Point p): target(p)&&call(Point.new(int,int));

Hi Shehzad,
SAPHELP on Advantages of ABAP Objects - Using ABAP - SAP Library says -
There are only two purposes for which procedural ABAP is essential:
· Encapsulation of classic screens in function modules.
· When you want to make functions available to other systems, but are not able to make class methods available externally using XI server proxies. In this case, you have to use function modules.

Calling ABAP class methods from JAVA application

Hi All,
I want to fetch ITS related information (SITSPMON Tcode) in my JAVA application. But i didnt find much BAPIs for the same. While debugging I came accross few class methods with help of which I can get the required information. So is there any way we can call and execute methods of ABAP classes through java application?
for e.g. I want to call GET_VERSION method of CL_ITSP_UTIL class.
Thanks,
Arati.

Hi,
Yes, as per my knowledge the only way to interact is using BAPI exposed as RFCs. So try to invoke those class methods in one CUSTOM BAPI and expose that BAPI as RFC and consume that RFC to get those details.

Lan,
An easy way for you to create your database under NT is using
the Oracle Database Assistant. It guides you in the creation of
your database. This is a GUI tool that should be in your Oracle
NT Program Group.

How to build my own HDR photoshop plugin?

Hi, I am a true fresh here and trying to build a HDR photoshop plugin, with an existing HDR merging algorithm in a static C lib. What I need to do is just to provide a file dialog to read in several images, then to process pixels of these images with the C lib, and last return a result image. In this case, which type of plugin should I focus? Automation, filter, or any others ? Besides that, what should be the key to read files and get their pixels? Would anyone be so kind to offer a hint? Thank you very much!

Hi Bowie,
Here is one possible approach...
1) Set "Do Not Use SOAP Envelope" in your Receiver SOAP Adapter.
2) Add this xsl as a second step in your interface mapping.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
    <env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
      <env:Body>
        <xsl:copy>
          <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
      </env:Body>
    </env:Envelope>
</xsl:template>
<xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>
</xsl:stylesheet>
You can then modify the soap envelope nodes above to create what you need.
