Access to whole payload in user defined function

Hi,
is there a way to access the whole XML payload in a user defined function or is it necessary to employ a Java mapping?
Kind regards,
Heiko

Hi,
did you have a look at this weblog:

Accessing container element in the User Defined Function

Hi All,
I am accessing a container element in the user defined function.
But it is not working. Actually i want to split a message(1800 records) into a batch of 200.
But it goes in a infinite loop.
Please can you tell me where i am wrong.
Smita
The code is :
public void SplitMsg(String[] a,ResultList result,Container container){
Object container1;
String counter;
int i,j=0;
container1 = container.getParameter("value");
if( container1 == null){
counter = "0";
else {
 counter = container.toString();
 j = Integer.valueOf(counter).intValue();
for ( i = j ; i <= j + 199 ; i++){
 if ( i >= a.length){
 container.setParameter("value","9999999");
 break;
 result.addValue(a);
 j += 200;
 counter = Integer.toString(j);
 container.setParameter("value", counter);

Here is another way to accomplish what you wanted.
For the target mapping, use this sequence for mapping
Source element -> removeContext -> Your User-defined Function -> Target Element
When defining User-Defined Function, select "Cache Queue" option.
Since you are using removeContext before calling the UserDefined function, your input to the user defined function will be a String array without ResultList.CC.
Now manipulate the array the way you want it, and build the ResultList result.
After every 200 records, use method
void addContextChange().
This will insert the ResultList.CC at the appropriate places.
Use Display Queue in the Mapping Editor to see the debug values.

Access Imported Archive in User Defined Function

Hi!
I want to access a XML file in an user defined function in a message mapping. The XML file is included in an imported archive. I need the information out of this XML file for configuring an extended receiver determination.
Does anyone know how to solve this?
Best regards,
Daniel

Hi Krishna,
a property file will be a solution but is has to be stored in the filesystem. In my scenario I prefer a file (not neccessary xml) which is editeable in the IR.
I tried something in this way (just for testing):
try {
     DocumentBuilderFactory factory = null;
     DocumentBuilder builder = null;
     Document document = null;
     Element element = null;
     factory = DocumentBuilderFactory.newInstance();
     builder = factory.newDocumentBuilder();
     document = builder.parse(Container.class.getResourceAsStream("routing.xml"));
     element = (Element)document.getElementsByTagName("BUSINESS_SYSTEM").item(0);
     return element.getNodeValue();
} catch (Exception e) {
     return "Crash: "+e.getMessage();
But it crashes, because the resource "routing.xml" cannot be found. I tried to add the namespace or the name of the imported archive or both as prefix, but it don't work. How can I find out under which address/url I can open the xml document?
Best regards,
Daniel

Accessing a Cache From an Oracle CQL User-Defined Function

According to the docs ...
I am to use the following element to set the cache property in my bean...
<wlevs:property name="cache" ref="cache-id"/>
However, when I set it, the assembly does not validate.
If I use <property>, I get a NullPointerException on each request when my processor runs.
Using the same CQL code..
Without the <property> tag, the call to the user-defined function works (but I don't have the cache attribute set obviously).
Here is the excerpt from my assembly...
<bean id="cacheFunction" class="ou.cep.function.CacheFunction">
<property name="cache" ref="myCache"/>
</bean>

<wlevs:processor id="myProcessor">
<wlevs:listener ref="CacheChannel"/>
<wlevs:function ref="cacheFunction" function-name="isValidID" exec-method="isValidID">
</wlevs:function>
</wlevs:processor>
To repeat, with the same CQL with the user-defined function call, if I remove the property element from the bean definition, I can call the function successfully (it just doesn't do what I need it to do). In this case, I am still using the ref=cacheFunction for the wlevs:function within the processor.
What am I doing wrong?

Edited by: fl0at on Oct 5, 2010 12:28 PM

The case is solved, not sure I could explain why, but...
This implementation of the user-defined function was a migration from an implementation using the same cache in the join. So, when I removed the cache reference in the source stream (where I am now executing a function that accesses the cache), the problem went away and everything is working.
I can explain further if there are questions.
If anyone has thoughts on this, please advise.
As always, thanks for the help.

Error in conditional map using User Defined Function

All,
In my mapping I basically have a user defined function that returns the filename of my inbound file from the adapter-specific message attributes (file adapter). I know this is coded properly because if I simply assign this function to my destination field I can see the filename in the payload XML.
However if I conditionally check that returned value using if,then,else I get an error message stating:
"During the application mapping com/sap/xi/tf/_MaterialData2ZcustProdMastMulti_ a com.sap.aii.utilxi.misc.api.BaseRuntimeException was thrown: RuntimeException in Message-Mapping transformation"
Essentially in my if I'm checking if the value returned by my user defined function is equal to the constant "SOMECONSTANT" then I'm setting my destination field to some other constant value. Otherwise it's equal to a different constant value.
Any thoughts?

Claus,
Thanks for the help. I actually had figured the problem out on my own. Sorry for not updating the thread sooner. What happened was this (as I suspected it wasn't related to my user defined function). For the newbies out there (of which I'm one) the problem was I was comparing strings in the graphical mapping tool using the Boolean "EQUALS" rather than the Text "EQUALSS".
Can you give yourself points for solving

User defined function during Mapping.

Hi,
I am trying to retrieve filename using user defined function.
The payload is simple.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:FTPTOFTP_MT_OB xmlns:ns0="urn://ftptoftp.com">
 <RECORD>
 <ROW>
 <EMPNO>723</EMPNO>
 <NAME>Jack</NAME>
 </ROW>
 </RECORD>
</ns0:FTPTOFTP_MT_OB>
the code for user defined function is
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
now during message mapping ...
do I have to have extra xml tag in the destination
message which is now having
<?xml version="1.0" encoding="UTF-8"?>
<ns0:FTPTOFTP_MT_IB xmlns:ns0="urn://ftptoftp.com">
 <RECORD>
 <ROW>
 <EMPNO>723</EMPNO>
 <NAME>Jack</NAME>
 </ROW>
 </RECORD>
</ns0:FTPTOFTP_MT_IB>.
If yes ...
Then how to graphically map this extra xml tag.

Hi Deepak,
If u want to display the source file name in ur output, then ur output XML structure there should be an extra tag for displaying the file name.
In message mapping, select the user defined function which u have already created and map it to the tag for storing the file name in the target message XML format.
There is a editor present to write the user defined function on the bottom left corner of the message mapping screen.
For this function u need to select the Simple Function Tab.

Neetu

User Defined Function Error - Can't find function

Hi All,
Version: 11.1.1.4
I created a user defined function and added it to one of my BPEL Processes. I can see the function in JDeveloper and can compile the project without issue. We placed the jar file out on the SOA Server following the oracle user defined function examples. After placing the file out on weblogic I was able to successfully deploy the project.
Oracle Deployment Steps:
To deploy user-defined functions to runtime:
1. Copy the user-defined function JAR files to BEA_Home/user_projects/domains/domain_name/lib or a subdirectory of lib. Where domain_name is the name of the Oracle WebLogic Server domain (for example, soainfra).
2. Restart the Oracle WebLogic Server.However, when I try to run the composite application I get the below error. I am not really sure why it can't find the Function? The jar is out on the server and the jar was added to the project?

Edited by: Scarpacci on Apr 1, 2011 6:06 AM

try putting the jar location explicitly in weblogic server's classpath i.e. add BEA_Home/user_projects/domains/domain_name/lib to wls classpath and restart server.

Error in simple user defined function

Like that it has shown 13 errors. I have given the package names in imports field what previous function has.

Hi,
Please see this from SAP help
a. You can import Java packages to your methods from the Imports input field, by specifying them separated by a comma or semi-colon:
You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since all message mappings require these packages and therefore import them. You should be able to access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the package under Import. In other words, you do not have to import it as an archive into the Integration Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
In addition to the standard packages, you can also specify Java packages that you have imported as archives and that are located in the same, or in an underlying software component version as the message mapping.
b. Create your Java source text in the editor window or copy source text from another editor.

Error in User defined function for dynamic file naming

Hi,
While creating User Defined function with this following code for dynamic fieldname
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
which options should i select for cache Value, Context, Queue
for Augument , what name shd i mention.
Regards,
Varun

Hi Varun,
I guess I have answered a similar question just a few minutes before on very similar post from you. Just pasting the same here .................
Are you trying to access the ASMA values from the SOAP header of the XI message for the source file name?
First of all you need to Set the Sender File Adapter for Set ASMA and then file name. So it will work fine when you actually run the scenario end to end.
But in the mapping tool when you test the mapping - there is not message header updated with the actual source filename - and whenever you try to read the FileName attribute in the message header from the UDF - it cannot find the object and returns a NullPointerException.
I would suuggest for your mapping tool testing to be successful, have a check in the java code for null values,
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
If (ourSourceFileName != null)
Return ourSourceFileName;
Return "NoFileName.txt";
Let us know if this works.

Using User Defined Function is SQL

Hi
I did the following test to see how expensive it is to use user defined functions in SQL queries, and found that it is really expensive.
Calling SQRT in SQL costs less than calling a dummy function that just returns
the parameter value; this has to do with context switchings, but how can we have
a decent performance compared to Oracle provided functions?
Any comments are welcome, specially regarding the performance of UDF in sql
and for solutions.
create or replace function f(i in number) return number is
begin
return i;
end;
declare
l_start   number;
l_elapsed number;
n number;
begin
select to_char(sysdate, 'sssssss')
    into l_start
    from dual;
for i in 1 .. 20 loop
    select max(rownum)
      into n
      from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
    into l_elapsed
    from dual;
dbms_output.put_line('first: '||l_elapsed);
select to_char(sysdate, 'sssssss')

for i in 1 .. 20 loop
    select max(sqrt(rownum))
      into n
      from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start
    into l_elapsed
    from dual;
dbms_output.put_line('second: '||l_elapsed);
select to_char(sysdate, 'sssssss')
    into l_start
    from dual;
for i in 1 .. 20 loop
    select max(f(rownum))
      into n
      from t_tdz12_a0090;
end loop;
select to_char(sysdate, 'sssssss') - l_start

end;
Results:

I find that inline SQL is bad for performance but
good to simplify SQL. I keep thinking that it should
be possible somehow to use a function to improve
performance but have never seen that happen.inline SQL is only bad for performance if the database design (table structure, indexes etc.) is poor or the way the SQL is written is poor.
Context switching between SQL and PL/SQL for a User defined function is definitely a way to slow down performance.
Obviously built-in Oracle functions are going to be quicker than User-defined functions because they are written into the SQL and PL/SQL engines and are optimized for the internals of those engines.
There are a few things you can do to improve function
performance, shaving microseconds off execution time.
Consider using the NOCOPY hints for your parameters
to use pointers instead of copying values. NOCOPY
is a hint rather than a directive so it may or may
not work. Optimize any SQL in the called function.
Don't do anything in loops that does not have to be
done inside a loop.Well, yes, but it's even better to keep all processing in SQL where possible and only resort to PL/SQL when absolutely necessary.
The on-line documentation has suggested that using a
DETERMINISTIC function can improve performance but I
have not been able to demonstrate this and there are
notes in Metalink suggesting that this does not
happen. My experience is that DETERMINISTIC
functions always get executed. There's supposed to
be a feature in 11g that acually caches function
return values.Deterministic functions will work well if used in conjunction with a function based index. That can improve access times when querying data on the function results.
You can use DBMS_PROFILER to get run-time statistics
for each line of your function as it is executed to
help tune it.Or code it as SQL. ;)

XI 7.0 Advnaced User Defined Function how to check Cache Entire Queue ?

Hi Friends ,
                   We are using XI 7.0 (PI)   . There is no Selection For Advanecd UserDefinedFunction . I think in this version Both will perfom in the User DefinedFunction Itself .
           There is option for Context and Queue While we are creating Function . If we select Queue is it eqivalent to Check box of Cache Entire Queue ? Is My assuption is correct ?
          I want to cache the Entire Queue ? Can you please tell me about this.
          My environment is like

you advanced user defined functions are now known as
Enhanced Functions (Cache = Context or Cache = Queue)
From Help -
+Features
Depending on which values are available in the cache for a user-defined function, different functions are available:
·        Simple Functions (Cache = Value)
This function type can process individual input values of a field for each function call. Therefore, simple functions expect strings as input values and return a string.
·        Enhanced Functions (Cache = Context or Cache = Queue)
This function type can process multiple input values of a field for each function call. Before you call the function, you can either import all the field values of a context or the whole queue for the field in an array.+

User - defined functions for calculating the taxes of state and country

hi expects,
how can write user-defined function in message mapping in which i want to calculate the states taxes (2500) and country taxes (5000) and give the result as grand total in output.please help me?

Hi,
Activities
1. To create a new user-defined function, in the data-flow editor, choose Create New Function (This
graphic is explained in the accompanying text), which is located on the lower left-hand side of the
screen. In the menu, choose Simple Function or Advanced Function.
2. In the window that appears, specify the attributes of the new function:
Name
Technical name of the function. The name is displayed in the function chooser and on the data-flow
object.
Description
Description of how the function is used.
Cache
Function type (see above)
Argument Count
In this table, you specify the number of input values the function can process, and name them. All
functions are of type String.
3. In the window that appears, you can create Java source code:
a. You can import Java packages to your methods from the Imports input field, by specifying them
separated by a comma or semi-colon:
You do not need to import the packages java.lang., java.util., java.io., and java.lang.reflect. since
all message mappings require these packages and therefore import them. You should be able to
access standard JDK and J2EE packages of the SAP Web Application Server by simply specifying the
package under Import. In other words, you do not have to import it as an archive into the Integration
Repository. You can also access classes of the SAP XML Toolkit, the SAP Java Connector, and the
SAP Logging Service (see also: Runtime Environment (Java-Mappings)).
In addition to the standard packages, you can also specify Java packages that you have imported as
archives and that are located in the same, or in an underlying software component version as the
message mapping.
b. Create your Java source text in the editor window or copy source text from another editor.
4. Confirm with Save and Close.
5. User-defined functions are limited to the message mapping in which you created the function. To
save the new function, save the message mapping.
6. To test the function, use the test environment.
The new function is now visible in the User-Defined function category. When you select this category,
a corresponding button is displayed in the function chooser pushbutton bar. To edit, delete, or add the
function to the data-flow editor, choose the arrow next to the button and select from the list box
displayed.
