Base64 decode with user defined function called from xslt

I have an xml document which has a segment containing a b64 encoded attachment.
I would like to decode the attachment as i map it.
I would think this could be done by using a java function of some kind being called from the xslt however i have very limited experience in this and none in how to code the decoding.
Anyone have an example ?
Cheers
Jon

yes SDN seems to have an example for you....it may not exactly solve your problem...but yes it not irrelevant.....you just need to do some R&D

Urgent Help Needed - Associating Statistics with User-Defined Functions

Hello,
We have an appication uses cost-based optimizer and uses a lot of TO_DATE and SYSDATE calls in FROM and WHERE clauses. For certain reasons, every call to TO_DATE and SYSDATE has been replaced by MY_TO_DATE and MY_SYSDATE respectively (which in turn call built-in functions). However, cost based optimizer is behaving strangely, which is understanble, based on the lack of user-defined functions statistics. I am under the impression that I should use something like:
ASSOCIATE STATISTICS WITH FUNCTIONS my_to_date DEFAULT SELECTIVITY ?;
ASSOCIATE STATISTICS WITH FUNCTIONS my_to_date COST (?,?,?);
ASSOCIATE STATISTICS WITH FUNCTIONS my_sysdate DEFAULT SELECTIVITY ?;
ASSOCIATE STATISTICS WITH FUNCTIONS my_sysdate COST (?,?,?);
but what should the values (?) be?. I guess I want to replicate TO_DATE and SYSDATE values, but how would I find out what they are? Thanks in advance...
P.S. I am also looking for workarounds (I cannot create a synonym for TO_DATE right?), so any help is welcome!!!

Hi emmalou69 ,
You told your actual parameter is
5, 5, 7.3 and 'z'
so change your method like
public static int test(int x, int y, double d, char ch)
because 5 - int; 7.3- float or double; z is char.
your method returns
public static int.
so you should return only int variable. but in your code you mentioned double. it's not correct.
The original code should look like
public class rubbish
     public static void main(String args[]){
          rubbish f = new rubbish();
          f.test(5, 5, 7.3 ,'z');
     public static int test(int x, int y, double d, char ch)
          int value;
          x = 5;
          y = 5;
          d= 7.3;
          ch = 'z';
          value =((int) d + x + y + ch);
          System.out.println( x + ch + d + y);
          return value;
}//here int value of z is 122.
and int(7.3) is 7
so 7+5+5+122 = 139.3
but value =((int) d + x + y + ch); returns 139. because you convert double to int that is 7.3 to 7
If it is useful, rate me duke dollars,
Thanks

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.

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.

Using decode in where clause with user defined function

Hi,
I have a below query which is failing as the function in the decode taking all cust_account_id as input parameter instead of the one which satisfies the condition in the inner query.So please provide a solution how can i pass only the selected one.
SELECT hca.cust_account_id
FROM hz_cust_accounts hca
WHERE hca.org_id=FND_PROFILE.value('ORG_ID')
AND hca.cust_account_id = (SELECT DISTINCT hcasa.cust_account_id
FROM hz_cust_acct_sites_all hcasa
WHERE hcasa.cust_account_id =hca.cust_account_id
AND hca.org_id = hcasa.org_id)
AND DECODE (hca.status , 'A', xx_ar_cust_audit_pkg.get_ship_to_order_type(hca.cust_account_id)) IS NOT NULL
Thanks,
Abhilash

I'm having to guess without access to your tables, but I think changing the IN to a join should produce the same results. The JOIN should be evaluated before applying the WHERE clause, so this may resolve your problem.
SELECT hca.cust_account_id
FROM   hz_cust_accounts hca
       INNER JOIN hz_cust_acct_sites_all hcasa
       ON    hcasa.cust_account_id = hca.cust_account_id
       AND   hca.org_id = hcasa.org_id
WHERE hca.org_id = FND_PROFILE.value('ORG_ID')
AND    DECODE (hca.status , 'A', xx_ar_cust_audit_pkg.get_ship_to_order_type(hca.cust_account_id)) IS NOT NULLAlternately, you could next part of the query and break the DECODE into the parent so it is evaluated after the inner query. This is likely uglier from a performance standpoint, though:
SELECT cust_account_id
FROM
SELECT hca.cust_account_id, hca.status
FROM   hz_cust_accounts hca
WHERE hca.org_id=FND_PROFILE.value('ORG_ID')
AND    hca.cust_account_id = (SELECT DISTINCT hcasa.cust_account_id
                              FROM   hz_cust_acct_sites_all hcasa
                              WHERE hcasa.cust_account_id =hca.cust_account_id
                              AND    hca.org_id = hcasa.org_id)
WHERE DECODE (status , 'A', xx_ar_cust_audit_pkg.get_ship_to_order_type(cust_account_id)) IS NOT NULL;

Problem with user defined function in XQUERY

Hi,
I have a file in which I store XQUERY. My java program reads this file and executes the xquery
and output the result. I have a working XQUERY in a file, which is something like :
<feed>
let $entries := for $x in collection('/path/to/atomStore.bdbxml')/entry[matches(id,'
.entry')]
order by $x/updated descending
return <entry xmlns="http://www.w3.org/2005/Atom">{$x/id,$x/title,$x/published,$x/updated,$x/link}
</entry>
let $latest := fn:subsequence($entries, 1, 10)
for $f in $latest return $f
</feed>
After adding the following simple function(I'm not calling it anywhere for the time being),
I'm getting an error
com.sleepycat.dbxml.XmlException: Error: Error in XQuery expression:
Unrecognized character 'a' (0x61) [err:XPST0003], line 33, column 2, errcode = XPATH_PARSER_ERROR
declare function xml:convertdate($date as xs:integer) as xs:string
let $months := ("jan","feb","mar","apr","may","jun","jul","aug","sep","oct","nov","dec")
let $month := $months[$date]
return $month
I couldn't find any error with the function syntax. Anyone has any idea?

Anoop

Hi Anoop,
The query and function work fine for me. What does the line and column information in the error point to?

Problem with User-defined function

Does anyone know how to make the user-efined functionto return a object. We know how to run a java class within cal script and pass the result to that java class. However, what we need is to be able to return the result in the form of a java class within the calling class. This is because we are calling the calscript within ejb and the ejb that executes the calscript needs to be able to get the result back.In our case, we are using webLogic EJB to execute a EDS calScript function. We don't know how to have the object created by EDS to be passed back to the EJB.Any insight will be greatly appreciated.Thanks,Anne

Help with User Defined Function

Hi
I want to code a UDF which comapres an array that contains "X" or empty values,with an array which contains only "X" and return a boolean array with boolean arguments (true/false)
I tried using the exisiting functions but I didnt find something relevant
Thx,Shai

Func 1: public void ChkForX(String[] a,ResultList result,Container container){
int flag = 0;
int count = 0;
for (int i = 0; i<a.length; i++)
if(a<i>equals("X"))
{flag = 0; }
else
{flag = 1;
count = count + 1;
if(count > 0)
result.addValue("1");
else
{result.addValue("0");
Func 2:
public void ChkSpaces(String[] a,ResultList result,Container container){
int flag = 0;
int count = 0;
for (int i = 0; i<a.length; i++)
if(a<i>equals(" "))
{flag = 0; }
else
{flag = 1;
count = count + 1;
if(count > 0)
result.addValue("2");
else
{result.addValue("3");
Kinda use both these functions with the same input then further build your logic ... but still i dont think you will get a array as output using UDF

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 12:22 PM
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.

Are Sql functions different from user defined functions ?

Hello,
SQL functions are built into Oracle Database and are available for use in various appropriate SQL statements. Do not >confuse SQL functions with user-defined functions written in PL/SQL.according to first paragraph of this document Sql functions are different from user defined functions . How is that ?
Is they really differ from each other ?

bootstrap wrote:
If you don't know what compilation is, please use Wikipedia or other online resources.I know what is compilation . But i was confused whether those sql functions are compiled in my machine when i install Oracle Database in my machine or they are pre-compiled .
As you said these Sql functions are pre-compiled , it is clear now that they are pre-compiled platform dependent code .
Can you provide actual source code of any SQL function , say SUM function .
I want to see it, how they have defined . Eagerly waiting for any reply. please help .
Edited by: bootstrap on Aug 19, 2011 11:50 AMYou can ask oracle if they give you their code. I doubt they will. However if you want to write you own user-defined aggregation function, there are examples in the documentation how to do that.

Calling ORACLE Store Procedure with parameters in user define function

Hi everybody,
We have a scenario connecting Oracle DB thru JDBC adapter.
We have to call store procedure with input parameter and output parameter to retrieve data from DB. The implementation was made using JDBC adapter by building the correct XML message with EXECUTE action, and it works fine.
Now we need to use DB lookup within mapping. I wrote users define function with SELECT statement (using the JDBC adapter) and it works fine but I need to call store procedure in ORACLE instead of SELECT statement.
I found lot of examples concerning DB lookup but none of them explained how to write UDF calling store procedure in ORACLE with input and output parameters.
I am looking for an example.
Thanks in advance,
Gigi

I agree with you, but issue is we have lots of existing store procedure, which we need to call where damn required. I am sure those will be few but still i need to find out.
If you think you are going to get existing MS Stored Procedures or Oracle Packages that had nothing to do with the ORM previously to work that are not geared to do simple CRUD operations with the ORM and the database tables, you have a rude awakening
coming that's for sure. You had better look into using ADO.NET and Oracle Command objects and call those Oracle Packages by those means and use a datareader.
You could use the EF backdoor, call Oracle Command object and use the Packages, if that's even possible, just like you can use MS SQL Server Stored Procedures or in-line T-SQL via the EF backdoor.
That's about your best shot.

Calling the function NUMBER_GET_NEXT from an XI User Defined Function

Hi there,
A number range object has been created on our XI server, called, ZBC_BKSTMT.
I need to call the function NUMBER_GET_NEXT (standard SAP function for number range objects) with the parameters:
NR_RANGE_NR = 01
OBJECT = ZBC_BKSTMT
Calling the NUMBER_GET_NEXT function will return a unique integer. However, i need to call it from a User Defined Function because I need to make use of the returned integer in my message mapping.
Thanks,

Calling PL/SQL user defined functions from ODI Constraints

Hi All,
We are trying to call user defined PL/SQL functions from ODI. We are able to call them from ODI's User functions. But when we are trying to call them from ODI Constraints under Models, it is throwing an error 'ORA-00920 invalid relational operator'. Kindly let me know if anyone has faced the same issue and got the resolution for the same. Thanks in Advance.
Regards,
Abhishek Sharma

Hi Ace,
Thanks for the response, the same error was coming in operator also.
I am able to call PL?SQL user defined functions from ODI Constraints. We have to first call ODI User functions from the ODI constraints as we cant call PL/SQL function (compiled in database) directly.
From the ODI User functions, we can then call the PL/SQL functions.
Please reach out to me if you need further details reg this.

Matscript node void ouputs when calling user-defined functions

Hi,
I have a (for most of you, probably simple) problem with calling user defined function within a mathscript node.
I have a script inside a MathScript node which calls three UD functions. When I try to output variables, LabView sets their type to void, so I cannot use them further. this would imply, that the script is nondeterministic, (since the types would get set at runtime). However, if I replace the call to the UD function with the actual contents of the function, the variable becomes deterministic. Now, since I have several call to these functions, I have no desire in writing all of them many time, introducing many variables etc. What would you advise me to do?
Find attached my scripts and functions.
I need this script running on a RT Target, and have been battling this for weeks, with almost no success!
Thanks, Regards,
Luka

Scripts.zip ‏2 KB

MArtin, hello!
As far as I know, LabView checks the syntax as you write in the MS Node, and since there is no X mark next to the line number, it indicates, that the syntax is correct. Since i have set the path to the UDF in both the VI options and in the general MAthScript setting, how does adding the path command help? even if I add path('directory') command, a yellow exclamation mark appears, saying the command is slowing down performance.
(this is the original help explanation:
The warning glyph indicates that LabVIEW operates with reduced error checking at edit time and slower run-time performance for the MathScript Node. The following conditions cause the warning glyph to appear. To remove the warning glyph from the MathScript Node and improve run-time performance, modify your script as follows to resolve the condition in your script:
Your script calls addpath or pathremove (legacy name rmpath), or calls cd, path, or userpath with one or more inputs, which change the MathScript search path list at run time. Remove these functions and use the MathScript page to configure the default search path)
Could you please post a screenshot of your VI, just to see, if you've got anything different set up?
I am running LV2012.

BUG in DB XML? (when dealing with modules, user-defined functions)

Hi,
this post can be related to Different results for the semantically the same queries but here examples are even simpler.
I have the module with one user-defined function:
module namespace tnt = "http://tntbase.mathweb.org/ns";
declare function tnt:filter-path($docs as document-node()*, $path as xs:string) as document-node()*{
$docs[dbxml:metadata('tnt:path') = $path]
};Then I have a query:
import module namespace tnt = 'http://tntbase.mathweb.org/ns' at 'file:/path/to/module/user-func.xq';
(: this variable is IMPORTANT in the query:)
declare variable $len := 3;
(: here goes the same function as in the module, but with different name :)
declare function tnt:filter-path2($docs as document-node()*, $path as xs:string) as document-node()*{
$docs[dbxml:metadata('tnt:path') = $path]
(:the query itself :)
tnt:filter-path(collection("xml_content.dbxml"), substring("a:/doc.xml", $len)) If I execute the query I get *0* results, if I use function tnt:filter-path2 (instead of module's tnt:filter-path) then I get the expected *1* result.
Also I experimented a bit with a query and got the following observations (independent from each other):
1) If I substitute $len by value *3* or *3.0*, then I get right results in both cases, i.e. if the query itself looks:
tnt:filter-path(collection("xml_content.dbxml"), substring("a:/doc.xml", 3)) 2) If I change the module's function so that it uses value comparison instead of general comparison, then I get the right results in both cases as well:
module namespace tnt = "http://tntbase.mathweb.org/ns";
declare function tnt:filter-path($docs as document-node()*, $path as xs:string) as document-node()*{
$docs[dbxml:metadata('tnt:path') eq $path]
};Please, help me out! I'm pretty sure it's a problem of DB XML and I'm struggling with it for a long time in this or that shape.
Thanks a lot in advance,
Vyacheslav

I upgraded from 2.5.13 to 2.5.16 and the bug disappeared. The reason why I didn't do it before was that I hadn't seen any relevant for me fixes in the release notes of 2.5.16 comparing to 2.4.13 (Actually I already have had two patches for two relevant issues in the 2.5.13 version)
Sorry for the false alarm.
