How to build a wsdl which can cater dynamically to number of attachments

We have a WebService client that calls a Webservice on the Server.
When the client calls the webservice , it passes the SOAP message(Header,Body & MIME attachments)and these attachments vary in number based on different business requirements.
We know how to build WSDL for server with static number of attachments,but no clue on how to build a wsdl which can cater dynamically to number of attachments comming from client request.
- thanks in advance

Hello,
We may have multiple approaches here depending of :
- which version of the product you are using
- what are your clients in term of stack, and API they are willing to use
- which encoding did you use for your WS (swa, swaRef or dime)
So for my answer I am documenting how to do it on OracleAS 10gR3 (10.1.3), using swaRef approach.
The easiest way is to exchange array of binary data and describle that in the WSDL, so in my case the WSDL element that is used will look like that:
<element name="filesResponseElement">
<complexType>
<sequence>
<element name="result" type="ns1:swaRef" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
This will generate from the Java code an array of AttachmentPart[].

How to create a structure which can hold a dynamic table as a field in DDIC

Hi ,
       I am designing a solution for a problem and have a unique requirement. I need to create a structure which can hold a field where dynamic table data can be stored. Let me illustrate with an example :
My structure ( say Z_output_struc ) will have the fields
Table_name Table_Data
My function module will have a table type of the above structure, so in effect ,my output can have multiple table names and related to each of them, there will be table data of that table name. The issue is how do I configure this in DDIC ?
I tried creating table_data as "Type ref to Data" but was stuck inside the func module when I tried to transfer data to this.
Any pointers as to how to think about this differently ?
Best Regards,
Girish

Hi Girish,
you start directly from the ref to data. You assign it to a field symbol and cast this to the type of the destination of your select. So you can directly add the reference to the cache:
I hope this example helps a bit (I took a form instead of a function module as it is easier to add here and used an hr table as kna1 is empty on my test system):
REPORT z_rwe_99_dyn_tab_cache.
* type definition
TYPES:
BEGIN OF _s_cache,
    table TYPE        tabname16,
    cache TYPE REF TO data,
END   OF _s_cache,
_t_cache TYPE STANDARD TABLE OF _s_cache.
* data declaration
DATA:
lv_table     TYPE tabname16,
lv_condition TYPE string,
lt_cache     TYPE _t_cache.
* define table and condition
lv_table     = 'HRP1000'.
lv_condition = 'plvar = ''01'' and otype = ''S'' and objid = ''50000016'''.
* get the result of a single table into the cache
PERFORM get_dyn_table USING
                        lv_table
                        lv_condition
                      CHANGING
                        lt_cache.
* form to read a single table
FORM get_dyn_table USING
                     iv_table     TYPE tabname16
                     iv_condition TYPE string
                   CHANGING
                     ct_cache     TYPE _t_cache.
FIELD-SYMBOLS:
    <lt_table> TYPE ANY TABLE.
DATA:
    ls_cache TYPE        _s_cache,
    lr_data TYPE REF TO data.
CREATE DATA lr_data TYPE STANDARD TABLE OF (iv_table).
ASSIGN lr_data->* TO <lt_table>.
SELECT * FROM (iv_table) INTO TABLE <lt_table>
    WHERE
      (iv_condition).
ls_cache-table = lv_table.
ls_cache-cache = lr_data.
APPEND ls_cache TO ct_cache.
ENDFORM.                    "get_dyn_table

Hi
Thanks for your fast replies.. I have created a new material and was able to create inventory thru MB1C. But I was not able to generate a goods delivery(VL01N) and billing document(VF01) for the sales order.
Error: No schedule lines due for delivery up to the selected date
Message no. VL248
Diagnosis
There are no schedule lines due for the given order item up to the date chosen.
System Response
The system does not create a delivery item for this order item.

What do you hope to achieve by this? A refresh? If so, a simple refresh of the old materialized view will do.
If you truly want to continue this road, you'll have to use the EXECUTE IMMEDIATE command to execute DDL commands from within PL/SQL.

I am using java.awt.Choice to display all the states in US, Canada and Mexico in that order. I need to make this list selectable using key board. ie, if i press A, it should first go to AL , then to AK etc. I have added the following code in the class which extends from Choice so that it i type A , it will go to AL. But subsequent key types for the same letter are not recognised.Please provide some pointers on how to do this.

In JS, how to save a bookmark which can open in main, not sidebar?

I did lots of search on the web. People have been struggling with this problem for many years.
The scenario:
My standard_weight.php takes height parameter either from $_GET or from $POST. The web page has a form to let users type in height.
Control-D can save the location, but not the height.
My page is too simple to ask users to create an account and save profile.
So I want to provide a link users can click and bookmark the current page with height.
<pre><nowiki><script language="JavaScript1.2" type="text/javascript">
function CreateBookmarkLink() {
title = "my ideal weight";
height = function_to_get_current_height_value();
url = "http://my.site.com/standard_weight.php?height=" + height ;
if (window.sidebar) { // Mozilla Firefox Bookmark
window.sidebar.addPanel(title, url,"");
} else if( window.external ) { // IE Favorite
window.external.AddFavorite( url, title);
} else if(window.opera && window.print) { // Opera Hotlist
alert("Sorry, your browser doesn't support this function." );
return false ;
if (window.external) {
document.write('<a onClick ="javascript:CreateBookmarkLink();">Add to Favorites</a>');
} else if (window.sidebar) {
document.write('<a onClick ="javascript:CreateBookmarkLink();">Bookmark Page</a>');
} else if (window.opera && window.print) {
document.write('<a onClick ="javascript:CreateBookmarkLink();">Add Bookmark</a>');
</script>
</nowiki></pre>
When the link is clicked , a dialog will pop up and the user can save the bookmark.
The problem is that when the bookmark is opened, it is in sidebar. The bookmark property has the check for "Load this bookmark in the sidebar."
Asking users to clear the check is not a friendly solution.
Is there anyway to get around this problem?
If you google this topic, you can find that people has been struggling with this for long time. I guess that they just end up with saying "sorry, your browser doesn't support this function." on Firefox.
Best wishes to Firefox !

How to create a text which can support more than 500 chars ?

Hi all:
    In my interactive form, I have one text, the value inside this text is longtext, the length will be more than 500 chars.
    My problem is now , if there is more than 100 chars, there will be duplicated chars in this text.
    Can I make this text support overlap ? when the value have too many chars, it will display in next row ? is it possible ?

Hi,
The 2 points are compulsory for multiline display.
Could you please let me know the following things.
1. Is that field is wrapped by any position content subform.If this is the case, try making flow content.
2. Is there any field below the text field and the 2 fields are wrapped in position content, In this case also make the subform as flow content.
Refer the example form FP_TEST_01 in SFP transaction.Check the subform and field properties.
Make a backup before making changes.
Thanks and Regards,

How to add a SwingComponent to a Scene which can resize dynamically ?

Hello,
I would like to add a custom swing component to a Scene (am using SwingComponent.wrap(..) approach) however I would like to know how to enable dynamic resizing of my component when my JavaFX scene is resized by the user ?
any info appreciated,
-A

I am going to have to award myself the Duke points. Surprising no one replied to this..
Anyway for anyone looking at this in future here is how I solved this problem:
Used the excellent Grid layout from JFXtras project allowing the following:
import org.jfxtras.scene.layout.Grid;
import org.jfxtras.scene.layout.GridConstraints;
import org.jfxtras.scene.layout.Row;Then my Stage was set like this (obviously this applies to any component) - I was just looking for Swing:
Stage {
    title: "JavaFX Dynamic Resize Layout"
    resizable: true
    var theScene: Scene;
    scene:
    theScene = Scene {
        content: [
            Grid {
                width: bind theScene.width
                height: bind theScene.height
                rows: [
                    Row {
                        cells: [
                            Cell {
                                hgrow: GridConstraints.ALWAYS
                                vgrow: GridConstraints.ALWAYS
                                halign: GridConstraints.HFILL
                                valign: GridConstraints.VFILL
                                content:swingComponent
}Simple really....

Build Labview Application which loads functions dynamically

I am not sure if this is possible for executables, but it works pretty well in the LabVIEW development mode.
I have a LabVIEW program which calls some functions (sub-functions) dynamically. In the develop mode, the sub-functions are in separate *.llb files. When a subfunction is selected from the menu of the main LabVEIW program, the main application searches a particular location/directory for a particular *.llb file; if the *.llb is found, it loads the vi and runs it, if not, it tells the user that the function is not available. The advantage of doing this is that I can add/remove/modify these sub-functions simply by puting in or taking out the *.llb file from that directory without causing any problem on the main program.
Would it be possible to do the same if I buid an LabVIEW executable application (I mean build/compile the main application first, and then add/remove functions by putting/removing some files in a directory)? If yes, then I can distribute new functions to users without having to re-compile the whole thing.
Thanks.

Hello Andrew,
When Using LOader method, there are a few things to take care of. It is not so terrible when you know what and why. Consider this If you change your executable, You have to rebuild and then you realize there was a small spelling mistake or a control was not aligned. Doing a double check is sometimes as important as good programming.
1. Path Issues - These you will have whether you build executable or release it as a library. This happens if you use relative path.
2. Use of native labview Vi's in your code - When the code changes, You want to distribute the new LLB. Well Use Save with Options and Choose "Application Distribution" Select "Entire Hierarchy", "Include Vi.lib Files" And "Runtime Menu" and "External Routines" If you want your App protected. Click Remove Diagrams. Again Make sure you don't lose your Original file if you choose this. All this saves the whole App as LLB.
Then your Loader has to call your Main Vi dynamically. How difficult is the path Issue to Call One Main Vi in a Vi Library. There is no Licensing Issue here as LV itself gives you this option.
I have used this method for a couple of 200 Vis or more Applications and constantly updated by changing the llb file without any hassle.
Good Luck!

RFC WHICH CAN USE DYNAMIC SQL AS INPUT AND SHOW COMPLETE DATA FOR TABLE

Hi Expert,
I am trying to create a FM like RFC_READ_TABLE. In this table we put table name and the field name for which we write a query and option for query we get the out put only for that field in this case.
My requirement is very similar to this. But here i want to enter any table name and in option i want to write dynamic sql query for any filed of table then i want data based on this so that it will display the entire table entries.
Like TABNAMELIKE     EKKO
OTHERCON     bukrs_k = 3000.
Based on this selection it has to show the entire table fields.
To make this easy to understand i made a custom FM which are getting data from table or view and i select any field and put query it will show the result.
FUNCTION ZDYNSQL_EKKO_EKPO.
""Local Interface:
*" IMPORTING
*"     VALUE(ERNAMLIKE) TYPE CHAR15 OPTIONAL
*"     VALUE(OTHERCON) TYPE CHAR50 OPTIONAL
*" TABLES
*"      VALUE STRUCTURE V_EKKO_EKPO
*TABLES : V_EKKO_EKPO, EKKO, EKPO.
DATA: STR_WHERE TYPE TABLE OF EDPLINE.
DATA: STR_LINE TYPE EDPLINE.
*CONCATENATE 'EBELN LIKE''' EBELNLIKE '%''' INTO STR_LINE.
        CONCATENATE 'ERNAM LIKE ''' ERNAMLIKE '%''' INTO STR_LINE.
        IF OTHERCON <> '            '.
        CONCATENATE STR_LINE 'AND' OTHERCON '            ' INTO STR_LINE SEPARATED BY SPACE.
        ENDIF.
      APPEND STR_LINE TO STR_WHERE.
      SELECT * FROM V_EKKO_EKPO INTO CORRESPONDING FIELDS OF TABLE VALUE WHERE (STR_WHERE).
ENDFUNCTION.
Now here is sample code of exact requirement.
FUNCTION ZDYNSQL_TABLE_READ.
""Local Interface:
*" IMPORTING
*"     VALUE(TABNAMELIKE) TYPE DD02L-TABNAME
*"     VALUE(OTHERCON) TYPE CHAR80 OPTIONAL
*" TABLES
*"      VALUE STRUCTURE DD02L
DATA: STR_WHERE TYPE TABLE OF EDPLINE.
DATA: STR_LINE TYPE STRING.
        CONCATENATE 'TABNAME LIKE ''' TABNAMELIKE '%' 'DD02L' 'TABNAME' INTO STR_LINE.
        IF OTHERCON <> '            '.
        CONCATENATE STR_LINE 'AND' OTHERCON '            ' INTO STR_LINE SEPARATED BY SPACE.
        ENDIF.
      APPEND STR_LINE TO STR_WHERE.
      SELECT * FROM DD02L INTO CORRESPONDING FIELDS OF TABLE VALUE WHERE (STR_WHERE).
ENDFUNCTION.
In this i put table name as EKKO and put sql query as bukrs_k = 3000 it provide a short dump.
How can i solve this problem. Please provide some input or modification
Thanks And Regards
Ranjeet Singh

Hi Kris,
I tried to make sample using that link you provide to me. How can i declare Global Interface in FM and in import parameter references like "REFERENCE(I_INTERFACE_CHECK) DEFAULT SPACE".
Also it uses a function-pool.
Let me tell you about my exact requirement about FM.
I want in import parameter input as any SAP Table name like
TABNAME TYPE EKKO
OPTIONS TYPE CHAR80
I want my output to be stored in TABLES attributes as per the table name entered in import parameter. In import parameter Table name can be any one of SAP tables and Option based on that particular table. Like if i go with table EKKO and put OPTIONS as
ebelp = 4 then TABLES attributes Tab contains all the relevant data for input.
Is there any way with the help of that i can put my data into internal tables. I tried to put in TABLES as VALUE LIKE ANY but it shows that generic are not allowed. Can you provide some sample on this.
I also getting exceptions like CX_SY_DYNAMIC_OSQL_SEMANTICS, SAPSQL_INVALID_FIELDNAME.
Waiting for your valuable reply.
Thanks And Regards
