Please help for User defined extension functions

the tutorial given for extension functions doesn't work as well as our new functions
even though i follow all the given steps and see the functions in my user defined extension functions tab in xslt map.
all the target nodes that use the extension function disappear in the resulted target xml.
please help.

have you compiled your java file and uploaded the jar file(containg the .class file and the Manifest.MF file) in the <OC4J_HOME>\j2ee\home\applib directory and then restarted the server??

XSLT Mapping - user defined Extension function

Hi to all,
can somebody helps me, please?
I need an own function, that can be used by the XSL Mapper. First I have only tried the sample given in Path <BPELPM>\integration\orabpel\samples\demos\XSLMapper\ExtensionFunctions
There is a java file with the defined functions and a xml file with the definition of this function for the mapper and last but not least a jar-file with the java class.
I have copied the jar to <JDEV_HOME>\jdev\lib\ext directory and in JDeveloper I have added SampleExtensionFunctions.xml to Tools->Preferences->XSL Map -> "User Defined Extension Functions Config File" field. After a restart of JDeveloper I find 2 new functions in the "User Defined Extension Functions" component palette page when a XSL Map is open. That's fine.
But if I test the mapping I get an error: "Failed to transform source XML.
java.lang.NoSuchMethodException: For extension function, could not find method org.apache.xpath.objects.XNodeSet.replaceChar([ExpressionCotext,]#STRING, #STRING)."
What is wrong?
Thanks in advance of your answer
best regard,

Oracle XML support Extension function.
For example:
If we would like to import FAQDBUri.class with user-defined java functions, like TranslateDBUri(), we can write XSL file like this:
<xsl:template match="/" xmlns:dburig="http://www.oracle.com/XSL/Transform/java/FAQDBuri">
<xsl:variable name="urladd" select="dburig:TranslateDBUri($url)"/>

Component Palette --- "User Defined Extension Functions" not visible

I added a User-Defined XPath Extension Function in JDeveloper 11.1.1.3.0 --> Tools > Preferences > SOA As given here http://download.oracle.com/docs/cd/E15523_01/integration.1111/e10224/bp_appx_functs.htm#BEIHEBIJ
But I am not able see "User Defined Extension Functions" section itself in the component palette. Do I need to enable anything for see the section.
Can somebody help.
Thanks

User Defined Extension functions XML file

Hi,
Can we define exception In custom XSLT function XML file.
Like i have following Custom XSLT function XML-
<?xml version="1.0" encoding="UTF-8"?>
<extension-functions>
<functions xmlns:uppercase="http://www.oracle.com/XSL/Transform/java/oracle.Uppercase">
<function name="uppercase:GetName" as="string">
<param name="fname" as="string"/>
<param name="lname" as="string"/>
</function>
</functions>
</extension-functions>
So in case i need to throw an exception in my java function GetName so how can i define that in XML?
Please give some suggestion?
Thanks.

Hi,
Thanks for your reply. When I created extensions.xml (as advised by you) and tried specifying it as User Defined Extension Functions Config file, I get the following error:
Invalid User Extension Functions Config File
Invalid value 'object' for attribute:'as' line 5 column 52
i.e. the following line:
<function name="extensions:getMSPDate" as="object">
Any pointers on what will be the correct value for attribute 'as' for element 'function'?
Also, what is the default namespace being used in the extensions.xml?
Is there a link for more documentation on the format for extensions.xml?

User defined extension functions

Hi,
I have a requirement to create a user defined extension function.
I followed the demo in the BPEL tutorials,and created the java function and then the extensions.xml.
I have registered the .xml file,and have copied the .jar to jdev/extensions directory.
Once i restart the Jdeveloper i am getting the following error.
Severe(0,0): file:/D:/Software/Jdeveloper/jdevstudio10133/jdev/extensions/LogP1ExtensionFunctions.jar does not contain an extension manifest.
Can anybody help me on this
Thanks in advance

Help! Can I have user defined extension function?

Under SQL Sever XML, I can write a xsl script like this:
<msxsl:script language="JScript" implements-prefix="myfunc">
function getvalue(nodelist,name,istag){
var subNode=nodelist.nextNode();
if(subNode == null) return('?');
if(istag == '') name = '@' + name;
var value=subNode.getElementsByTagName(name);
return((value == null)?'':value);
</msxsl:script>
and I can call this function in the xsl, obviously, msxsl supported by microsoft. I know that Oracle XML support Extension function, but you can tell here that I want a user defined function while not a predefined function. Can I have such feature with Oracle XML, and How? Thanks.

Oracle XML support Extension function.
For example:
If we would like to import FAQDBUri.class with user-defined java functions, like TranslateDBUri(), we can write XSL file like this:
<xsl:template match="/" xmlns:dburig="http://www.oracle.com/XSL/Transform/java/FAQDBuri">
<xsl:variable name="urladd" select="dburig:TranslateDBUri($url)"/>

Soa 11g and jdeveloper 11g user defined extension function

I have developed a set of extension functions,
in design time for the previous version, I can put the deployment file (jar file) that contains the extension functions in the %JDEV_HOME%\jdev\lib\ext directory and jdeveloper recognizes the set of extension functions if previously i have defined an xml descriptor with every one of the functions i need to include in the panel.
Now, with the jdeveloper 11g i have tried the same, and jdev recognizes the functions, but when I am going to test one transformation that includes the extension function, the parser is not founding the jar file; the error (in spanish) is:
XML-22045: (Error) Error de funcion de extension: No se ha encontrado la clase '
Falta la clase: aac._shared.extensions.xsl.XmlW3cDomFunctions
Clase Dependiente: oracle.xml.xpath.XSLExtFunctions
Cargador: main:11.0
Origen del Codigo: /C:/.extracted/jdevstudio1111/lib/xmlparserv2.jar
Configuraci≤n: system property PCLMain.createExtensionManagerLoader()
Esta carga se ha iniciado en main:11.0 mediante el mΘtodo loadClass().
La clase que falta no esta disponible desde ningun origen de codigo o cargador del sistema.
my dude is:
+ at design time, where can I put the jars with extension functions to make one transformation function used in a mediator component can works fine?
+ at runtime, where can I put those libraries? (in the previous version, we can put this libraries in the %APP_SERVER%\j2ee\home\applib, or create one shared library and reference it in the oracle.bpel.common shared library declaration of the server.xml configuration file).

Hi,
please post this question to the JDeveloper 11 forum. Please translate the messages into English as well

Modifying .PRM file for user defined database functions

Hi,
Currently we have the BOXI 3.1.8 Universe in oracle database and we are planning to migrate to SQL server 2008.And the universe contains few oracle functions and user defined functions in the universe objects.
In the way of migration we are planning to have both Oracle and SQL Server database connecting to single universe. To make the universe generic we have identified the objects using user defined functions and trying to push it to the database.
Since there are a few differences in the way oracle and SQL Server functions are invoked, we have decided to edit the .PRM files available in the path D:\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\dataAccess\connectionServer\jdbc , so that we have a common way of invoking the functions.
Invoking functions:
SQL Server : <SchemaName>.<function>
Oracle: <function>
1.Is there any problem if I edit the .PRM?
2.Whether these changes will work fine?
3.Whether the reports will run fine if I use those objects in the reports?
Thanks,
Lavanyaa

Hi Lavanyaa,
The PRM files actually state the functions that are normally available in a database, including the standard format.
They are what drives the list of functions available when you build the SELECT definition or CONDITION definitions in Information designer... The fact that a function needs aggregation or/not is also determined in there.
However:
The SQL that you provide in the universe is what will be sent to the database and that must be 'understood' by the database.
So it's not as simple as changing the PRM file and you will be able to speak 'universal' SQL in your universes.
Fortunately:
That complexity is taken away from you when you create a multisource database.
You will speak 'data federator' SQL in the universe. Data federator will take care of translating it to the right syntax for each database. Notice you will probably need some customization to determine how a SQL will be handled when you need to query two databases, as the default is not automatically the best way performance wise.
Hope this helps,
Marianne

User Defined External Function - How to work?

I have defined some external functions in java by following the description in
C:\OraBPELPM_3\integration\orabpel\samples\demos\XSLMapper\ExtensionFunctions
I can use my functions in JDeveloper, but they do not work on the Oracle BPEL engine.
Is it enough just to place the jar-file in <OC4J_HOME>\j2ee\home\applib and add the jar-file in class-path (as described)?
What about the xml-file specifying the functions (called SampleExtentionFunctions.xml in the documentation)?
Should this file be copied to <OC4J_HOME>\... ?
Here is the error message I get by running my service:
XPath expression failed to execute.
Error while processing xpath expression, the expression is "ora:processXSLT("TransformationInput.xsl", bpws:getVariableData("inputVariable", "request"))", the reason is java.lang.NoSuchMethodException: For extension function, could not find method org.apache.xpath.objects.XNodeSet.leadingZeros([ExpressionContext,] #NUMBER)..
Please verify the xpath query.
______________ MY JAVA CODE EXAMPLE: _____________________________
package extentionfunctions;
This is a sample XSL Mapper User Defined Extension Functions implementation class.
public class JavaExtensionFunctionsBpel
* Inserts leading zeros to a text, if this starts with a digit.
* Else the return value will be the same as the given text.
* The return value will have the specified length.
public static String leadingZeros(String text, int len)
{ String retur = text;
char c = (text == ""?'0':text.charAt(0));
if ('0'<=c && c<='0'+9) { // Is first char a digit?
retur = "";
int n = len - (text == ""?0:text.length());
for (int i=0; i<n; i++) { // Insert zeros:
retur = '0' + retur;
retur = retur + text;
return retur;
* Removes leading zeros from a text.
public static String removeLeadingZeros(String text)
{ String retur = text;
int pos = 0;
int len = (text == ""?0:text.length());
for (int i=0; i<len; i++) {

pos++;
return retur;
public static void main(String[] args)
{ // Basic test of functions:
int len = 5;
String s = "1234";
String r;
System.out.println("leadingZeros("+s+","+len+")="+(r=leadingZeros(s,len)));
System.out.println("removeLeadingZeros("+r+")="+removeLeadingZeros(s));

Flemming Als

Flemming, it looks like somthing is wrong in the xsl that it still goes to org.apache.xpath.objects.XNodeSet package instead of yours ..
I created a sample that illustrates the usage of this functions (even with 2 params, different types).
Java class (com.otn.samples.xslt.CustomXSLTFunctions)
package com.otn.samples.xslt;
public class CustomXSLTFunctions
<function name="extension:multiplyStringAndInt" as="number">
<param name="base" as="String"/>
<param name="multiplier" as="number"/>
</function>
public int multiplyStringAndInt (String pString, int pMultiplier)
int base = Integer.parseInt(pString);
return base * pMultiplier;
XML descriptor:
Note the types (in the java class and the xml descriptor)
for java:base -> string and for xslt:base -> string
for java:multiplier -> int and for xslt:multiplier -> number
<?xml version="1.0" encoding="UTF-8"?>
<extension-functions>
<functions extension:multiplyStringAndInt="http://www.oracle.com/XSL/Transform/java/com.otn.samples.xslt.CustomXSLTFunctions">
<function name="extension:multiplyStringAndInt" as="number">
<param name="base" as="string"/>
<param name="multiplier" as="number"/>
</function>
</functions>
</extension-functions>
Definition of variables in the process:
(as you can see, the base is a string - I do the conversion in my method, and the return value
is converted to a string by the engine)

<element name="CustomXSLTFunctionProcessRequest">
<complexType>
<sequence>
<element name="base" type="string"/>
<element name="multiplier" type="int"/>
</sequence>
</complexType>
</element>

<element name="CustomXSLTFunctionProcessResponse">
<complexType>
<sequence>
<element name="result" type="string"/>
</sequence>
</complexType>
</element>
Using the new function in the XSL transformation:
- watch out for the namespace declaration (xmlns:sample="...")
- and the usage (sample:multiplyStringAndInt)
<xsl:stylesheet version="1.0"
xmlns:ldap="http://schemas.oracle.com/xpath/extension/ldap"
xmlns:xp20="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.Xpath20"
xmlns:bpws="http://schemas.xmlsoap.org/ws/2003/03/business-process/"
xmlns:plnk="http://schemas.xmlsoap.org/ws/2003/05/partner-link/"

xmlns:ora="http://schemas.oracle.com/xpath/extension"

xmlns:orcl="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc"
xmlns:client="http://xmlns.oracle.com/CustomXSLTFunction"
exclude-result-prefixes="xsl plnk ns0 client ldap xp20 bpws extension ora orcl">
<xsl:template match="/">
<client:CustomXSLTFunctionProcessResponse>
<client:result>
<xsl:value-of select="extension:multiplyStringAndInt(/client:CustomXSLTFunctionProcessRequest/client:base,/client:CustomXSLTFunctionProcessRequest/client:multiplier)"/>
</client:result>
</client:CustomXSLTFunctionProcessResponse>
</xsl:template>
</xsl:stylesheet>
Then I created a jar file with the class (and for testing the xml descriptor in it)...
and put it into j2ee/home/applib directory

Hi All,
I have created an alert for engineering module in R12. It got tested and was working fine. when the user testing it, while trigger the alert getting the error, "APP-ALR-04106: Please correct the user-defined SQL statement for this alert".
when verified the alert, it got verified and ran also. It parsed the query successfully and when run it fetched few records.
Need help in resolving the issue.
Thanks in advance.

Hi Sri;
I have already gone through the Note: 948037.1. But this note is related to 11i. The solution provided in the Note is for 11i.
I am facing this issue in R12. Is this patch applicable to R12?I belive its not. But u can check Solution part 4 for your instance, at least it can give you idea. The other note in metalink related bug and all for R11 too.
I belive its better way to rise Sr while waiting other forum user response to that thread

Crystal Report Templates for User-Defined Objects

Hello Experts,
I am running SAP B1 8.8 PL11. In the current patch SAP has default Crystal Reports that can be used as Layouts for Invoices, Credit Memo's so on. Is it possbile to have layouts for user defined objects ( say for instance i have a customized form under sales module, can i import a crystal template for this customized form?). In the report layout manager i don't see an option to import user-defind objects.
Any help would be appreciated.
Thanks,
Praneeth

If this is still a problem please re-post to the SAP Integration Kit forum.

How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCI

Hi
we are using Timesten 11 version and as per the documentation, it doesn't support User-Defined Aggregate Functions.
So we are looking for alternatives to do it. Could you please provide your expert voice on this.
Thanks a lot.
As the following:
create or replace type strcat_type as object (
cat_string varchar2(32767),
static function ODCIAggregateInitialize(cs_ctx In Out strcat_type) return number,
member function ODCIAggregateIterate(self In Out strcat_type,value in varchar2) return number,
member function ODCIAggregateMerge(self In Out strcat_type,ctx2 In Out strcat_type) return number,
member function ODCIAggregateTerminate(self In Out strcat_type,returnValue Out varchar2,flags in number) return
number
How can I use User-Defined Aggregate Functions in Timesten 11? such as ODCIAggregateInitialize ?

Dear user6258915,
You absolutely right, TimesTen doesnt support object types (http://docs.oracle.com/cd/E13085_01/doc/timesten.1121/e13076/plsqldiffs.htm) and User-Defined Aggregate Functions.
Is it crucial for your application? Could you rewrite this functionality by using standart SQL or PL/SQL?
Best regards,
Gennady

Using log4j in User definied Extension Function java class

Hi
I am having a java class where I defined all the user defined XSL Functions.
I used System.out.println for printing.
But I want to use log4j. But when I use this to debug. It is not recognising only.
Could you please tell me why this is not working in this class?
Regards,
Praveena

Hi Anuj,
I can see the below error in the default log file:
09/08/11 16:25:21 log4j:ERROR A "org.apache.log4j.RollingFileAppender" object is not assignable to a "org.apache.log4j.Appender" variable.

Could you please tell me what is the problem?

User-Defined Aggregate Function in oracle

Somebody knows if in oracle 10g is possible to create a User-Defined Aggregate Function?
Sometingh like my_sum, that aggregate the values in a way that i want...
select manager, my_sum(salary)
group by manager
In internet i've found rellay notingh for oracle 10g...can somebody help me? Thank's in advance!

Thank's to everybody!!! I've made my custom function sum_distinct
create or replace type AggregateCD as object
( nb                   number,
     ListOfDistinctValue clob,
    static               function ODCIAggregateInitialize(sctx IN OUT AggregateCD) return number,
    member               function ODCIAggregateIterate(self IN OUT AggregateCD, value IN VARCHAR2) return number,
     member               function ODCIAggregateTerminate(self IN AggregateCD, returnValue OUT number, flags IN number) return number,
    member               function ODCIAggregateMerge(self IN OUT AggregateCD, ctx2 IN AggregateCD) return number
create or replace type body AggregateCD is
   static function ODCIAggregateInitialize(sctx IN OUT AggregateCD) return number is
     begin
         sctx := AggregateCD(0,null);
         return ODCIConst.Success;
    end;
    member function ODCIAggregateIterate(self IN OUT AggregateCD, value IN VARCHAR2) return number is
        ListOfValue CLOB:=self.ListOfDistinctValue ;
     begin
         self.nb:=self.nb+to_number(substr(value , INSTR(value, ';', 1, 1)+1 ,length(value)));
        return ODCIConst.Success;
    end;
    member function ODCIAggregateTerminate(self IN AggregateCD, returnValue OUT number, flags IN number) return number is
     begin
          returnValue := self.nb;
          return ODCIConst.Success;
    end;
     member function ODCIAggregateMerge(self IN OUT AggregateCD, ctx2 IN AggregateCD) return number is
     begin
         self.nb := ctx2.nb;
         return ODCIConst.Success;
    end;
end;
CREATE OR REPLACE FUNCTION sum_distinct (input VARCHAR2) RETURN number
PARALLEL_ENABLE AGGREGATE USING AggregateCD;you can use so:
select sum_distinct(distinct t.primary_key||';'||t.import)
from table1 t, table2_with_bad_join
it's the same of
select sum(t.import)
from table 1

Please help for User defined extension functions
