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

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.

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?
Regards,
Matias.

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;

Using a User Defined Function as a constraint within a temporary table.

Hello,
I am trying to create a temp table that uses a UDF in a constraint. I'm getting the following error message
Msg 4121, Level 16, State 1, Line 1
Cannot find either column "dbo" or the user-defined function or aggregate "dbo.CK_LoseTeamSportExists", or the name is ambiguous.
I've tested the function and it works in other contexts. Any idea? All code below:
Thanks,
- Bryon
create function dbo.CK_LoseTeamSportExists (@loseteam int, @sportid int)
returns bit
as
begin
declare @return bit
if exists
select TeamID, sportid from Link_TeamSport
where
TeamID = @loseteam
and
SportID = @sportid
set @return = 1
else set @return = 0
return @return
end
go
create table #check
SportID int
,WinTeamID int
,LoseTeamID int
,check
(dbo.CK_LoseTeamSportExists(LoseTeamID,SportID) = 1)

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums.
>> I am trying to create a temp table that uses a UDF in a constraint. <<
You do not understand how SQL or any declarative language works!
We do not use UDFs (procedural programming)
We do not use bit flags (assembly language).
We do not use temp tables (mag tape files).
We do not use integer as identifiers (what math do you do on them?)
Your silly “Link_TeamSport” implies a pointer chain; we have no links in SQL. Where is the DDL?
Constraints are always predicates in any declarative language.
Do you know why you have to create a local variable to pass the non-relational flag back to the calling environment? FORTRAN I and II! These early languages has to use hardware registers in the first IBM computers to return results. In your ignorance, you mimic
them!
We do not use if-then-else control flow in any declarative language. We have CASE expressions that we put where you have a local variable getting an assignment.
I see you also put the comma at the start of the line. We did that with punch cards, so we could re-use them 50 years ago.
In SQL, we would use REFERENCES to assure a team reference exists. We use names for teams because they are entities, not quantities:
CREATE TABLE Game_Results
(sport_name CHAR(10) NOT NULL PRIMARY KEY,
win_team_name CHAR(12) NOT NULL
REFERENCES Teams(team_name)
ON DELETE CASCADE,
lose_team_name CHAR(12) NOT NULL
REFERENCES Teams(team_name)
ON DELETE CASCADE,
CHECK (win_team_name <> lose_team_name));

Henry,
Do you have a structure for your response...if you do then you can do extended reciever det with sync/async..shouldent matter, i just tried it and i dont get any error.
in your reciever determination..Check the box for standard rec det then add your first condition..of the value of a field to true..then send to A..
then you select add condition..and add for second reciever..that should be it, you shouldent need a bpm for such a simple scenario..it definetly is an overkill.

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.

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.

How to use StreamTransformationException in user-defined function?

Hi,
I'm doing a DBLookup (using Java pgm in one of my Imported Java archives) for populating one of the fields in message mapping. If the DB connection fails, I want to terminate the mapping by throwing a StreamTransformationException from within a user-defined function.
I require urgent help in this regard.
Thanks in advance.

Hi,
I had the same problem. I failed to find the way how to throw a StreamTransformationException in my user-defined function. But I used another exception: NullPointerException. Yes, I know, this is not an elegant solution...
Best regards,
