How to develop a user defined function to convert XML to Base64Binary

Hello,
I am trying to develop a solution in which I need to convert XML into Base64Binary so that I can then write this Base64Binary opaquely to a file (as opaque data is nothing but Base64 encoded data)
So, I want to develop a flow in which:
*File Adapter (read file based on some XSD) ----{color:#99cc00}XML{color}-----> BPEL/ESB input ----{color:#99cc00}XML{color}--------->Transform ----{color:#99cc00}Base64Binary{color}---------File Adapter that writes files opaquely*
{color:#000000}
What should be the signature of such a function. How I can pass the input to it.
TIA
{color}

Think i got something here How to convert String to base64Binary in BPEL process
but its BPEL all the way, how to get hold of input in an ESB process?

How to use a user defined function in XI

Hi Experts,
I would like learn how to use a user defined function in Xi during mapping . Is there any step by step on that.
Besides during when me make communcaton channels I see the following tabs...Paramters ..Identifiers ...Module...
The module that is given here ...where and how it is used.

Hi,
You can write UDFs in java in Graphical mapping to enhance your XI Graphical mapping functionality
The steps for doing it would be:
1. Click on Create New function Button found on Bottom left corner on your XI Mapping window.
2. Write your java code.
3. Run the Mapping Test as usual.
>>The module that is given here ...where and how it is used.
The adapters in the Adapter Framework convert XI messages to the protocols of connected external systems and the other way around. When doing so, some
functionality might need to be added specific to a situation which is possible with the use of custom modules.
Typical example would be validation of file content when using a File Adapter or modification of the message payload to a common content structure which is not supported by any of the standard SAP modules.
An Adapter module is developed as an Enterprise Java Bean and is called locally by the Adapter.
An example on modules :

How many types of user defined functions are there?

how many types of user defined functions are there?

Hi Ramakrishna,
A user-defined function is only visible in the message mapping in which you created it. You can insert the function in the data-flow editor as a standard function by using the User-Defined function category.
You can use the following user-defined functions:
1.Simple functions, which can process individual field input values for each function call. Simple functions therefore expect strings as input values and return a string.
2.Advanced functions, which can process several field input values for each function call. You can import either all field values of a context or the whole queue for the field in an array before calling the function. For more information, see Advanced User-Defined Functions.

     Advanced user-defined functions, which can process more than just individual field values.Instead, you can import a complete context or an entire queue for a field as an array before your function is called

How to use a user defined function in where cluase condition

Hi,
I have designed a query by selecting some columns in the tables and some columns are retrieved directly from table and some columns are passing to a user defined function. Now my requirement is i need to use that user defined function result in oracle where condition clause.
Ex : select marketing_user_id,get_name(marketing_user_id),item_id,get_item_name(item_id),get_country_name(country_id),
from
where get_item_name(item_id) in ('x','y','z')
and get_country_name(country_id) in ('India','America','China');
When am i trying the query by above format i am getting the wrong resultset.
BR,
uma

I am not sure why your getting the wrong results but you should seriously reconsider the approach your are taking. Using functions like this is very ineffecient and should be avoided at all cost.

How to implement a user-defined function in a mathscript node

I am trying to use a mathscript node that includes self-defined functions, but I always get an error. I tried to run an NI-example: MathScript using Riemann Zeta.vi ,and I got the same error I get when I run my own programmes:MathScript Node'MathScript Node' (zeta): User-defined function contains an error. I didn't change anything in that example, so what could be wrong?

Try the Mathscript forum instead. Good luck.
(Maybe start reading this, for example)

How can I find user defined functions in oracle

Hello All,
I need to find out what are the user defined functions available in my schema?
Please let me know on what system tables shall I query and find out the user defined functions?
Thanks,

Thanks Satish,
One more query. Can I find what are the parameters that needs to be passed?
Here is what I have to do..
I have to find all the accessible user defined functions. If I select one of them in my UI, I need to show the parameters used in the respective function.
Please let me know if these parameters are stored anywhere..

How to distinguish the User-Defined-Function from Oracle Build-In function

Hi Friends,
I could get the function list form all_objects table by the SQL:
select * from all_objects where object_type = 'FUNCTION'
but there is no column in all_objects specify the function is build-in or user-defined.
But I found in SQL Server there is a column "is_ms_shipped" in the sys.all_objects table. This column will specify the object is build-in or user-defined. I want to get the equivalent column in Oracle but failed.
Could anyone tell me how to solve this problem?
Thanks,
Ricky

Thanks Pavan.
But if an user connects to database using "conn /as sysdba" syntax and creates a function. This user-defined funtion goes into the "SYS" schema also. I know it is not the best practise to create objects using sys user so I think your solution is right.
Regards,
Ricky

Question in User Defined Functions....

Hi,
Can I develop new User Defined functions in ABAP programming language rather than in Java? If Yes, how and if not why?
Sorry, if this is a petty question as I am in the process of learning XI.
Thanks,
Monica

Hi,
yes it's a stantard function module
which you can call from abap mapping
there's no possibility to create user defined function
that you could use in graphical mapping in abap
take a look at this document on how to do abap mapping:

Whether i would write user-defined function convert euro into rupee or USD

hi expects,
whether it need to right user defined functions for convert the currency into euro or any other currency into rupee or USD.as my client is having business in different region.please help me.
Edited by: santosh kumar sethis on Apr 24, 2008 10:39 AM

I suggest to use a UDF and call an RFC function\BAPI in the ERP system.
Currency conversion values are maintained in the ERP system by the Financial people so you'll have the most updated rates.(maybe even according to the date of purchase)
So 3 scenarios come to mind:
1. if the message is send from a 3rd party system or from ERP ,the currency must be converted already in the message,
2.the RFC of the ERP will do the conversion or you.
3.Find a currency conversion web service that has parameters of date and currency so you'll do the conversion as accurate as possible.
bare in mind:
there might be inconsistency of the money values due to the change in currency from the time the order was placed in the system till the time of entering the SAP .ask for the advise of a financial person so you wont do any mistakes in conversion.
ANY WAY - don't use hard coded constants in XI mapping for currency conversion.
Good luck.

How can I use Seeburger java functions on SAP XI's user defined functions?

Hi All,
As my title implies; how can I use Seeburger java functions on SAP XI's user defined functions? I've tried searching over the net in tutorials regarding this topic but I failed to find one; can someone provide me information regarding my question? thanks very much.
best regards,
Mike

Hi Mike !
You should check your documentation about which java classes you need to reference in the "import" section of your UDF. And also deploy the java classes into the java stack or include them as a imported archive in integration repository...it should be stated in the seeburger documentation.
What kind of functions are you trying to use?

Matias.
