Easy RFC lookup from XSLT mapping using a java class (getting Error)

Hi All,
I am trying to implement the sample scenario for calling RFC from xslt with the help of wrapper class. I am getting following error.
com.sap.aii.mapping.lookup.LookupException: Internal lookup service is not registered. Invoking the lookup service is only supported in the Integration Builder test environment or in the Integration Server runtime environment. at com.sap.aii.mapping.lookup.LookupService.getService(LookupService.java:400) at com.sap.aii.mapping.lookup.LookupService.getChannel(LookupService.java:285) at com.sap.aii.mapping.lookup.LookupService.getChannel(LookupService.java:318) at dk.applican.xi.mapping.lookup.RfcLookup.execute(RfcLookup.java:55) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at com.sap.engine.lib.xsl.xpath.functions.JLBFunction.execute(JLBFunction.java:145) at com.sap.engine.lib.xsl.xpath.ETFunction.evaluate(ETFunction.java:110) at com.sap.engine.lib.xsl.xpath.XPathProcessor.innerProcess(XPathProcessor.java:54) at com.sap.engine.lib.xsl.xpath.XPathProcessor.process(XPathProcessor.java:41) at com.sap.engine.lib.xsl.xpath.XPathProcessor.process(XPathProcessor.java:49) at com.sap.engine.lib.xsl.xslt.XSLVariable.process(XSLVariable.java:125) at com.sap.engine.lib.xsl.xslt.XSLNode.processFromFirst(XSLNode.java:228) at com.sap.engine.lib.xsl.xslt.XSLTemplate.process(XSLTemplate.java:256) at com.sap.engine.lib.xsl.xslt.XSLStylesheet.callTemplate(XSLStylesheet.java:1310) at com.sap.engine.lib.xsl.xslt.XSLCallTemplate.process(XSLCallTemplate.java:102) at com.sap.engine.lib.xsl.xslt.XSLNode.processFromFirst(XSLNode.java:228) at com.sap.engine.lib.xsl.xslt.XSLElement.process(XSLElement.java:241) at com.sap.engine.lib.xsl.xslt.XSLNode.processFromFirst(XSLNode.java:228) at com.sap.engine.lib.xsl.xslt.XSLElement.process(XSLElement.java:241) at com.sap.engine.lib.xsl.xslt.XSLNode.processFromFirst(XSLNode.java:228) at com.sap.engine.lib.xsl.xslt.XSLTemplate.process(XSLTemplate.java:256) at com.sap.engine.lib.xsl.xslt.XSLStylesheet.process(XSLStylesheet.java:445) at com.sap.engine.lib.xsl.xslt.XSLApplyTemplates.process(XSLApplyTemplates.java:158) at com.sap.engine.lib.xsl.xslt.XSLNode.processFromFirst(XSLNode.java:228) at com.sap.engine.lib.xsl.xslt.XSLTemplate.process(XSLTemplate.java:256) at com.sap.engine.lib.xsl.xslt.XSLStylesheet.process(XSLStylesheet.java:445) at com.sap.engine.lib.xsl.xslt.XSLStylesheet.process(XSLStylesheet.java:381) at com.sap.engine.lib.jaxp.TransformerImpl.transformWithStylesheet(TransformerImpl.java:392) at com.sap.engine.lib.jaxp.TransformerImpl.transform(TransformerImpl.java:234) at com.sap.aii.ibrun.server.mapping.MappingTransformer.transform(MappingTransformer.java:153) at com.sap.aii.ibrun.server.mapping.XSLTMapping.executeStep(XSLTMapping.java:67) at com.sap.aii.ibrun.server.mapping.Mapping.execute(Mapping.java:91) at com.sap.aii.ibrun.server.mapping.MappingHandler.run(MappingHandler.java:77) at com.sap.aii.ibrun.sbeans.mapping.MappingRequestHandler.handleMappingRequest(MappingRequestHandler.java:88) at com.sap.aii.ibrun.sbeans.mapping.MappingRequestHandler.handleRequest(MappingRequestHandler.java:63) at com.sap.aii.ibrun.sbeans.mapping.MappingServiceImpl.processFunction(MappingServiceImpl.java:80) at com.sap.aii.ibrun.sbeans.mapping.MappingServiceObjectImpl0.processFunction(MappingServiceObjectImpl0.java:131) at sun.reflect.GeneratedMethodAccessor482.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at com.sap.engine.services.ejb.session.stateless_sp5.ObjectStubProxyImpl.invoke(ObjectStubProxyImpl.java:187) at $Proxy22.processFunction(Unknown Source) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at com.sap.engine.services.rfcengine.RFCDefaultRequestHandler.handleRequest(RFCDefaultRequestHandler.java:95) at com.sap.engine.services.rfcengine.RFCJCOServer.handleRequestInternal(RFCJCOServer.java:113) at com.sap.engine.services.rfcengine.RFCJCOServer$ApplicationRunnable.run(RFCJCOServer.java:171) at com.sap.engine.core.thread.impl3.ActionObject.run(ActionObject.java:37) at java.security.AccessController.doPrivileged(Native Method) at com.sap.engine.core.thread.impl3.SingleThread.execute(SingleThread.java:94) at com.sap.engine.core.thread.impl3.SingleThread.run(SingleThread.java:162

Hello,
I have the same issue as stated above.
At runtime sometimes the mapping fails however when executing the mapping from ESR (test operation mapping) with the same payload it is executed succesfully (lookup is to system that is the senderservice of the scenario).
Anybody a clue.
Also clearing mapping cache etc. did not solve the problem.
Thanks,

Code Sample: Easy RFC Lookup From XSLT Mappings Using a Java Helper Class

Hi everyone,
This is just a shameless plug for my article: <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14">Easy RFC Lookup From XSLT Mappings Using a Java Helper Class</a>. I hope you're interested in reading it, and I welcome your comments in this thread.
Kind regards,
Thorsten

Hi Stefan. Thanks for your post. I have already done that. It still does not work. As a base for my java helper class I have usesd Thorstens code.
The problem is quite confusing. I will try to ouline both issues here.
First of all, when try to test from within the Operation Mapping, I always get a java error saying it cannot find the communication channel (it is there and working because I have tested it with the RFCLookup in graphical mapping). I have found a way to work around this, and that is to uncheck the "Use SAP XMLToolkit" checkbox --> switch to test tab, enter my ReceiverService in the parameter tab (header parameter) --> switch back to Definition tab, check the "Use SAP XMLToolkit" checkbox --> switch to Test tab and run the test. Then the XSLT and call to java helper class will work. Of course this is not really something you want to do all the time. Maybe there is a bug.
Secondly, it never works when I try to do it "live". I am using a file adapter to pick up one file, convert it and a file adapter to drop the converted file. I get the following error code in SXMB_MONI.
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

Using an XSLT without a call to a java helper class, works just fine.
I am totally at a loss here. Any more input would be much appreciated.

Java RFC lookup from XSLT mapping

I tried to implement a generic Java RFC Lookup class to be called as a Java extension from my XSLT mapping. I found the How-To-Guide "Easy RFC lookup from XSLT mappings using a Java helper class" ([Easy RFC lookup pdf site|http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/05a3d62e-0a01-0010-14bc-adc8efd4ee14?quicklink=index&overridelayout=true]) and tailored the source code to my XSLT program. I am getting the error "Variable '$inputparam' has not been bound to a value". Can anyone tell me what I am missing? I am not familiar with java at all, and only moderately familiar with XSLT.

> I am getting the error "Variable '$inputparam' has not been bound to a value". Can anyone tell me what I am missing?
At runtime the variable does not get value. You need to assign value to the variable inputparam. Just curious why dont use the RFC lookup graphical which is very easy and no need to handle java programming. You need to configure just reciever RFC communication channel.

Java Error in RFC Lookup in XSLT Mapping usinf Java helper class

Hi All,
I am doing RFC Lookup in XSLT Mapping using Java Helper class.
The Lookup works fine when called one RFC at a time However my requirement is I want to do 2 Lookups.
Both Lookups works when done individually however when I call both lookups in one mapping I get following error "javax.xml.transform.TransformerException: DOMSource whose Node is null."
Following is the code I have written in XSLT for the lookup:

     </xsl:template>
My Question: Am I doing anything wrong? Or Is it possible to call multiple lookups in one XSLT?
Thanks and Regards,
Atul

Hi Atul,
I had the same problem like you had.
The main Problem is that with the example code the request variable is created as NodeList object. In XSLT a variable is somekind of a constant and can't be changed. As the request object is empty after the first request the programm fails at the following line:
Source source = new DOMSource(request.item(0));
So I've created a workaround for this problem.
In the call of the template I've put the request as a parameter object at the template call:
<xsl:with-param name="req">
<rfc:PLM_EXPLORE_BILL_OF_MATERIAL xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
<APPLICATION>Z001</APPLICATION>
<FLAG_NEW_EXPLOSION>X</FLAG_NEW_EXPLOSION>
<MATERIALNUMBER><xsl:value-of select="value"/></MATERIALNUMBER>
<PLANT>FSD0</PLANT>
<VALIDFROM><xsl:value-of select="//Recordset/Row[name='DTM-031']/value"/></VALIDFROM>
<BOMITEM_DATA/>
</rfc:PLM_EXPLORE_BILL_OF_MATERIAL>
</xsl:with-param>
With this change the request will be provided as a String object and not as a NodeList object.
Afterwards the RfcLookup.java has to be changed to the following:

Then you need to compile and upload this class and it should work.
I hope that this helps you.

RFC Lookup in XSLT Mapping

Hi,
I am trying to do RFC Lookup in XSLT.
I got this excellent mapping tool here at sdn:
RFC Lookup by Thorsten Nordholm Søbirk
But I am having problems when I uses this in a multi-record mapping. (many-to one) with lookup for every element.
Has anyone done IDOC with XSLT and RFC lookup (PI 7.11) ? Can you share the XSLT or experience?
Thx for sharing

Hi @ Fariah Ali
here is the mapping:
Inbound: IDOC HRMD_A07 (from ALE replication)
We only want to have Infotypes IT0001, IT0002, IT0050
Outbound:
<?xml version="1.0" encoding="utf-8"?>
<mt_I004_Time_Stammdaten>
    <Datensatz>
          <PersNr>PERSNR</PersNr>
          <Name>ENAME</Name>

Reg - XSLT Mapping using stylesheet exception during test

Hi experts,
I am new to SAP PI. Currently i am working on PI's XSLT Mapping using Stylusstudio.
I got error *Transformer Configuration Exception occurred when loading XSLT <name>.xsl; details: Could not compile stylesheet*.
I tried test by selecting SAP XML TOOLKIT too, then i am facing
*com.sap.engine.lib.xml.parser.NestedSAXParseException: Fatal Error: com.sap.engine.lib.xml.parser.ParserException: XMLParser: Prefix 'a' is not mapped to a namespace (:main:, row:4, col:15)(:main:, row=4, col=15) -> com.sap.engine.lib.xml.parser.ParserException: XMLParser: Prefix 'a' is not mapped to a namespace (:main:, row:4, col:15)*.
Kindly help me to overcome this issue.

Hi,
Simply your XSLT file is not a well-formed XML. Check your syntax. You could also use the XML Tools plugin to Notepad++ to help you determine where the syntax error is precisely.
Moreover, this error "Prefix 'a' is not mapped to a namespace" might mean that you are using a tag: <a:something>, but "a" is not properly declared as a namespace, for instance like: xmlns:a="something.sap.com".
Hope this helps,
Greg

Is is possibel to do an RFC Lookup from The Graphical Mapping?

Greetings,
While doing a message mapping I need to get the value from R3 system using an RFC, is it is possible ?

Hi
we can do by using rfc look ups
Lookup in mapping is the feature provided by SAP to lookup the data in the target R/3 or DB systems with the API provided.
You need to write UDF in order to implement the API's provided by SAP.Consider the below example
VendorNumber-UDF--CURR
The scenario is legacy to SAP. The legacy system doesn't provide the currency details. But the target field need's to be populated with currency value.
"The business rules says there are values maintained in SAP Table where if you pass VendorNumber it will return thr currency to you"
So what you can do? You can write UDF implementing SAP Provided API's and do a lookup in the SAP System and get back the currency value and populate them in CURR field.
I hope it clears a bit.
Please find the below blogs
DB Lookup: /people/siva.maranani/blog/2005/08/23/lookup146s-in-xi-made-simpler
RFC Lookup:https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a03e7b02-eea4-2910-089f-8214c6d1b439
There are three types of look ups u can do
RFC look up
SOAP look up
JDBC look up
What is Lookup and why we need:
Within an XI mapping it is a common requirement to be able to perform data lookups on-the-fly. In particular, there may be a need to look up some data that is maintained in an R/3 application.
In the error handling topic we have seen the different validations which need to be performed on file. This can be done through Lookup.
Some use cases:
Look up material number from table MARA.
Look up cost center budget.
Look up employee information.
Look up unit-of-measure (UOM) information from table t006a.
Lookup for raising an alert.
The purpose of the lookup may be:
To perform application-level validation of the data, before sending it to the backend.
To populate fields of the XML document with some additional data found in the backend application.
This is a form of value transformation.
The "value mappings" offered by XI are not adequate in this case, since the data would have to be manually entered in the Integration Directory.
There are two ways in which we can do lookup:
Call lookup method from GUI mapping.
Call lookup method from XSLT mapping.
Lookup method from GUI mapping can be called using any of the following ways.

Can we test RFC lookup from IR?

Hi All,
Can we test RFC Lookup from IR-Message mapping? If yes How?
Like we can test Graphical mapping in test tab of Message Mapping.
Regards

Hi Sarvesh,
got it...
But when I am displaying queue.
I am getting POPUP window saying -->
Problem When Displaying Queue
Cannot perform RFC lookup
Can you please guide how to resolve this?
Since RFC Lookup in run time uses Receiver RFC adapter.
I tested RFC adapter is configured properly.

How to return Values from Oracle Object Type to Java Class Object

Hello,
i have created an Oracle Object Types in the Database. Then i created Java classes with "jpub" of these types. Here is an example of the type.
CREATE OR REPLACE TYPE person_type AS OBJECT
ID NUMBER,
vorname VARCHAR2(30),
nachname VARCHAR2(30),
geburtstag DATE,
CONSTRUCTOR FUNCTION person_type RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_id NUMBER) RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_vorname VARCHAR2,
p_nachname VARCHAR2,
p_geburtstag DATE) RETURN SELF AS RESULT,
MEMBER FUNCTION object_exists(p_id NUMBER) RETURN BOOLEAN,
MEMBER PROCEDURE load_object(p_id NUMBER),
MEMBER PROCEDURE save_object,
MEMBER PROCEDURE insert_object,
MEMBER PROCEDURE update_object,
MEMBER PROCEDURE delete_object
MEMBER PROCEDURE load_object(p_id NUMBER) IS
BEGIN
SELECT p.id, p.vorname, p.nachname, p.geburtstag
INTO SELF.ID, SELF.vorname, self.nachname, SELF.geburtstag
FROM person p
WHERE p.id = p_id;
END;
My problem is, that if i use the member function "load_object" from my java app it doesnt return the selected values to the java class and i dont know why. I use the java class like this:
PersonObjectType p = new PersonObjectType();
p.load_object(4);
There is a reocrd in the database with id = 4 and the function will execute successful. But if i try to use "p.getVorname()" i always get "NULL". Can someone tell me how to do that?
Thanks a lot.

CallableStatement =
"DECLARE
a person_type;
BEGIN
a.load_object(4);
? := a;
END;"
And register as an out parameter.

I then found one suggestion that the problem might involve permissions. The suggestion was to right click PhotoshopElementsOrganizer.exe in its installation folder (which on my computer is at at D:\Photo\Elements 11 Organizer) and run Organizer as an administrator. This also failed.
I don't understand why running the exe from the installation folder would have worked.
I would have simply tried to run that exe from its real location :

How to set the classpath and path from the jsp to call java class function

I have a requirement to call a java class function which returns a hashmap object from the jsp. The java class in present in one jar file and that jar file is location somewhere in unix path. So the requirement is to set the classpath for that jar file and then create the object of the java class and then call the function.
If any one know how to achieve it, please reply as soon as possible.
thanks in advance,

It is never advisable to store large data sets in the session. But it will depend on a lot of factors:
1. How costly is the query retrieving the data from the database?
If it's a complex query with lots of joins and stuff, then it will be better to store it in the session as processing the query each time will take a lot of time and will decrease performance. On the other hand if the query is simple then it's advisable not to store it in the session, and fetch it each time.
2. Are there chances for the data to become stale within a session?
In this case storing the data is session will mean holding the stale data till the user session lasts which is not right.
3. How many data sets does the session already holds?
If there are large no. of data sets already present in the session, then it's strictly not advisable to store the data in the session.
4. Does the server employ some kind of caching mechanism?
Using session cache can definitely improve performance.
You will have to figure out, what is the best way analyzing all the factors and which would be best in the situation. As per my knowledge, session is the only place where session specific data can be stored.
Also, another thing, if the data set retrieved is some kind of data to be displayed in reports, then it would be better to use a pagination query, which will retrieve only the specific no. of rows at a time. A navigation provided in the UI will retrieve the next/previous data set to display.
Thanks,

Yes.
Download Photoshop Elements products | 13, 12, 11, 10
However, the real issue is why the program is not working. Did you install anything recently?
When you tried to re-install from the disk, did you shut off the antivirus program temporarily?
Have you tried a system restore to a point in time when the program was working properly?
