Logging in java defined functions

Hi,
Are there any means of logging in java defined functions used in mapping?
Regards
Yann

Hi,
You can do MapTrace in the UD
MappingTrace trace = container.getTrace();
trace.addInfo("trace Text");
Thanks,

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.

User Defined Function is not recognizing java class in IR.

Hi All,
i have written one normal java class, and i imported that java class into IR using imported Archive as a .jar file,
it will add just two values .
now in message mapping i created one user defined function in that
iam trying to call this java class. while testing it is showing error as cannot resolve symbol java class name
so experts please help me in this or it would be appreciate if any one will provide
step by step process of one java class and one USD just to add two numbers.
thanks in advance,
jasmine .

Hi,
The steps are as follows:
1) Create a java file with .java extension.
2)Compile it to create a .class file.
3) Create a zip file for this .class file using any compressed archive program(ex-winrar)
4) Upload this zip file as an imported archive ,save and activate.
When you go to this archive,below , you can see your .class file with the older path,for below ex:
ObjRecord.class jxl/biff/drawing/
you have to give following entry in imports section:
jxl.biff.drawing.ObjRecord;
Please try this and let us know if this works.
Thanks.

User defined function in java for message mapping

I wrote the following user defined function in java for message mapping and mapped vendor with this. The aim of this function is to write a error file at defined path when i send empty Vendor value from File to RFC-Function module BAPI_PO_CREATE. The "err.txt" error file is not written when i execute in TEST but the value "ERROR" is returned to destination Vendor Field.
public String validation(String a, Container container) {
//write your code here
if (a.equals("")) {
try {
String source = "Vendor cannot be empty";
char buffer[] = new char[source.length()];
source.getChars(0, source.length(), buffer, 0);
for (int i = 0; i < buffer.length; i +=2)
f0.write(buffer);
f0.close();
FileWriter f1 = new FileWriter("/10.10.0.55/sapmnt/trans/edixiin/err.txt");
f1.write(buffer);
f1.close();
catch (IOException e) {}
return "ERROR";

Hi Senthil,
Check these things :
1) Whether you have permission to create a file in that directory.
2) try giving this
10.10.0.55
sapmnt
trans
edixiin
err.txt
3) Also check for permissions.
Hope this will help you.

User-defined function(java)

hi expects,
how to write user defined finction in javain meesage mapping.please help me.

Hi Rohit,
In order to create UDFs, you need to have a basic idea about using Core Java. Also, based on the kind of functonality of the code, you will need to know if you require any extra jar files.
To create a UDF, all you need to do is click on LHS icon in the graphical mapping editor. Also, keep in min that the input and otput of a udf is always in strings.
To test your functions, you can either use the test tab present in the mapping editor or you can even use the following editor(blog by Sravya):-
/people/sravya.talanki2/blog/2006/07/24/integrating-java-editor-in-xi-integration-stack
I think info will be enough for you to start off with creating and using UDFs:)
This link for User Defined Functions,
http://help.sap.com/saphelp_nw04/helpdata/en/d9/718e40496f6f1de10000000a1550b0/content.htm
Writing use defrined functions in XI is quite simple. Create a simple UDF, give the import parameters and then just go ahead with the logic coding and then return the output from the UDF.
Just remember that all inputs and outputs to an UDF are always Strings.

Java user-defined function for mapping a complex structure

All,
Hope one of you can help me with this. I have a structure with over 15 fields and would like to concatenate all the fields into one target field and while I do this, I need to ensure that each field is padded with blanks as defined the data type. Can one of tell me if this is possible with a java user-defined function and if so, what type of logic is needed.
Input_MT
Field_1 string len=10 "need"
Field_2 string len=6 "java"
Field_3 string len=7 "help"
Field_4 string len=8 "asap"
etc,
Output_MT
DataOut string "need java help asap "
(for some reason the exact spaces in between the words disappear in my Preview message)
I have several fields in the input mt and therefore I find graphical mapping using concatenate and my own user defined function padWithSpace too messy.
Thank you for you help.

Hi,
If your final req is to write all these fields next each other in a file, you can configure this in receiver file adapter by specifying the fixed length for each field.
If you want the padded string as your MM o/p, you can create a simple user defined funtion with 15 fields as input and 15 constants for their lengths, and find out the length of the each string and pad it with required no of spaces.
int max_len = 10;
int actual_len;
actual_len = a.lengh();
for(int i=0; i < (max_len-actual_len; i++)
a = a.append(" ");
return a;

Java class within user defined function

Hi all,
in order to have a JDBC-lookup java function "globally" in XI i created a java class and imported it to XI as an imported Archive (i have to do the lookup within a mapping). I then can include the class to a user defined function. However the problem is now that this works fine within one Software Component Version but when i want to use it in several SWCV i have to import the jar to every SWCV. My question is therefore if anybody has already had this problem and if there is another possible solution - maybe deploying the class to XI using SDM?
Thank you for your thoughts.
Mathias

hi Markus,
>>>>My question is therefore if anybody has already had this problem and if there is another possible solution - maybe deploying the class to XI using SDM?
if you do that then you'll have to remember about it
every time you import a new SP or upgreade your XI
this is not standard so SAP may always overwrite it
and your interfaces will stop working
consider importing it for every SWCV

Error in simple user defined function

Hi all,
I have seen one simple user defined function on scenario. Now it is working fine. Same code I have used another place. But it is giving some errors

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.

Need help with user defined function

Hello SDN,
I need some help with a user-defined function. My source message contains multiple
generic records (1000 char string), and my target message is 1 header record,
then multiple generic records. See description of source and target messages below:
Source:
GenericRecordTable 1..unbounded
    Row (1000 char string)
Target:
Field1 (char5)
Field2 (char5)
Field3 (char5)
IT_Data
    GenericRecordTable 1..unbounded
      Row (1000 char string)
Basically, what I need to do in my user defined funtion is to map the first record
in my source record to the 3 header fields, then map all of the rest of the records
(starting from line 2) into the GenericRecordTable.
Can someone please help me with the code for the user defined function(s) for this
mapping?
Thank you.

Custom Defined Function problem - @JSUM

I'm having trouble getting custom defined functions to work on my 64-bit Essbase 11.1.1.3 instalaltion.
I'm following the instructions and example provided in the 11.1.1 Essbase Database Administrator guide, pages 495 - 498.
I'm using the sample calc provided along with the sample CDF (copied from the book - with the locale automatically added by Essbase):
//ESS_LOCALE English_UnitedStates.Latin1@Binary
"New York" = @JSUM(@LIST(2.3, 4.5, 6.6, 1000.34));
The source code for the @JSUM is as follows:
public class CalcFunc {
public static double sum (double[] data) {
int i, n = data.length;
double sum = 0.0d;
for (i=0; i<n; i++) {
double d = data ;
sum = sum + d;
return sum;
Registering the function worked just fine - I just cut and pasted from the manual:
create function Sample.'@JSUM'
as 'CalcFunc.sum'
spec '@JSUM(memberRange)'
comment 'adds list of input members';
When I attempt to run the calc script Sample.Basic, I get this error:
Error: 1200324 Error compiling formula for [New York] (line 2): operator expected after [@JSUM]
Also, I notice the following error in the Sample application log file when it starts:
[Tue May 11 15:23:43 2010]Local/Sample///Info(1002035)
Starting Essbase Server - Application [Sample]
[Tue May 11 15:23:43 2010]Local/Sample///Info(1200480)
Loaded and initialized JVM module
[Tue May 11 15:23:43 2010]Local/Sample///Error(1200442)
Java Virtual Machine error
[Tue May 11 15:23:43 2010]Local/Sample///Warning(1200490)
Wrong java method specification [CalcFunc.sum] (function [@JSUM]): []
Can anyone provide guidance to how to resolve this error?

Turns out this problem can be resolved by the proper JDK settings.
I was using JDK 1.6 to compile my code (as its a pain to find and download the 1.5 JDK). Essbase uses a 1.5 JVM.
The following errors can be resolved by the proper javac settings:
Java Virtual Machine error
Wrong java method specification
Here is the new javac line I used with JDK 1.6:
javac -target 5 CalcFunc.java
