ABAP XSLT Extensions or XSLT (XI imported archive)?

Hi all,
I would like to know which is having better performance in a scenario with a significant number of messages.
I know that ABAP XSLT Extensions is based in XSLT 1.0 and have some features of XSLT 2.0. So, for me it means some limitations and a disadvantage compared with all of XSLT 2.0 standard can offer.
But, my question is related with performance and I just want to know which is faster.
Thanks in advance,
Cheers,
Ricardo.

Hi Ricardo,
abap xslt has one great advantage
abap stack does not have to communicate with
java stack to perform the - so no RFC calls for mapping
with many messages that might influence their flows
but it wuold be best if you could just test it
in YOUR environment (there are many test tools -
like Loadrunner from Mercury) or you can write your own scripts
and just test in your particular examle which one is better

Imported archives

How to import externally defined mapping programs in to Imported archieves? could anybody help me....
Thanks in advance,
Manoj

Hi Manoj,
            XI supports 4 types of mappings
                        1. Message mapping
                        2. XSLT MApping
                        3. JAVA Mapping
                        4. ABAP Mapping.
                 If you go with message mapping or ABAP mapping no need to use imported archive. If you want to implement XSLT or JAVA mapping then only you need to import those programmes into imported archives. when import the external programms(XSLT or JAVA) to the Imported archives then should keep those file as a ZIP. The ZIP files only can import to the Imported Archives.
Thanks,

Looking for example - abap xslt - that uses xslt document() function

Hello,
I'm looking for an example that shows the use of abap xslt with the xslt document() function. Using the xslt document() function seems like a straightforward way to use xslt to create a result xml document by processing the content of two or more
source documents. For example, if source document A.xml and aux.xml are available in memory as xstringand using stylesheet ztransformwhat would be the argument for the document() function to associate aux.xml. Thanks for any insight.

Hi,
Sorry, perhaps I should have been clearer! The function that I picked just to test what you need to do just happened to return a string that contains SPAN tags with style attributes. The actual function code is:
create or replace FUNCTION out_string_fn
 RETURN VARCHAR2
IS
 CURSOR emp_cur
 IS
 SELECT ename
 FROM emp;
 v_string VARCHAR2 (4000);
BEGIN
 v_string := ' ';
 FOR c IN emp_cur
 LOOP
 v_string :=
 v_string
 || ''
 || c.ename
 || ''
 || ', ';
 END LOOP;
 RETURN v_string;
END;And this returned a naff list in green (see [http://apex.oracle.com/pls/otn/f?p=55041:57] and click the Test button) - but it does show that you can style the validation error messages

Overloaded Java methods in XSLT extensions?

Hello,
when using Java classes as XSLT extensions, is it possible to use overloaded methods at all? I get "XSL-1042: Extension function error: Overloaded method 'format'" when doing that.
I studied Steve Muench's book, pages 607-611, and came up with the following:
Declared namespaces: "Date" for java.util.Date, "DateFormat" for java.text.DateFormat.
Declared XSL variables: "now" as "Date:new()", "datefmt" as "DateFormat:getDateInstance()".
Value of "Date:toString($now)" works fine. However, value of "DateFormat:format($datefmt, $now)" causes the XSL-1042 error.
Is there any way around this?
--Jere
null

The way around it is to create a wrapper function yourself that doesn't depend on overloading, and then exploit the overloading within your wrapper function call.

SQL extension for XSLT

Hi,
I am working on SQL extensions on XSLT using xalan SQL Library. My requirement is to insert some data which comes in the form of XML to one of our tables. I tried to write a sample XSLT to retrieve the data from the database (thought I can change it to insert once I succeed retrieving data). The XSLT is not working. I think I am able to connect to database successfully but not able to retrieve any results. Any help would be greatly appreciated.
Thanks in advance,

No idea. You didn't mention pquery in your original post, and I don't even know what that is (even after googling it).
Anyway, your problem is the same as in your first post. You haven't done your research. All you know is it's "not working". Find out in what way it is not working and then post a detailed question.

Brainstorming imported Archives (JAVA) versus Z-TABLEs (ABAP)

Hi everybody,
we got very complex processes and I would like to ease them:
Instead of fixedValues in Message-Mapping we use CSV-files and store them in the imported archives.
In different message-mappings we read the CSVs via UDF.
The problem is that the CSV get often updated by the R/3-agents. So we have a lot of administrative work to communicate with the agents, import the files, transport and so on.
Thats the reason I am thinking of creating z-tables where the agents can maintain the values instead of updating the CSV. Also the agents would be able to transport the z-table entries.
But as the z-tables are resided on the ABAP-stack we would have change our graphical message mappings to ABAP-Mappings. This would be to much work for us and is not practicable.
Do you see a workaround or a best practice I do not see?
Thanks Regards
Mario

Hi,
Instead of doing all this work, you can do in simple
Use RFC LOOKUp in XI Mapping to pull the values based on the input value and Maintain the ZTable in ABAP Stack of XI or in R/3 itself.
RFC Lookups
The specified item was not found.
Use this crazy piece for any RFC Mapping Lookups!

ESB XSLT Extension Functions

Hi
Could anybody tell me if we can use log4j in the java class which we write for XSLT Extension Functions which will be used in ESB XSL mappings?
It is not recognizing log4j only.It is not giving any error also.
Thanks
Praveena

Thanks Kanchan.
This is talking about how to implement Extension functions.
I have done this. but my question I am not able to use log4j for debugging purpose in this java class. It is not recognising this.
We need to use logger instead of System.out.println .
Thanks

Xslt extension

I'm looking to write an Xslt extension to help produce Html-output. For part of the tags produced, some information in the Xml needs to be checked and the output changed accordingly. The idea I had was to dynamically add a piece of xsl to each stylesheet used. The question is rather simple: What's the "cleanest" way of writing a thing like this? So that there would be least possible "obscuration" of the code in the different stylesheets?
Tommy Sedin

Combining the XSLs isn't the problem. Calling the
templates inside the "extension stylesheet" in a nice
and clean way is. I hate having 4-5 lines of code to
call a template, when it should be possible to have
just 1.XML is a verbose language, isn't it?
I appreciate your answers, but - as I said in my
previous post - you're giving solutions to something
that is already solved without even touching the
problem I actually need help with. And I'm sorry if
I'm making "smart ass comments", but I don't much
appreciate you attacking my skills as a programmer and
systems architect. There is a reason why I've solved
something in a harder, more clumsy way than what
everyone else does.Yes, people always have their reasons for doing things. And sometimes those reasons are bad reasons. Questioning a design is not an attack, it's just a question. So there's no need to take it personally. However, I really didn't read your first reply properly, and that didn't help.

Where to put property files used by XSLT extensions?

Still fighting with Java XSLT extensions. I have narrowed the
problem down: my XSLT extension cannot find its property file,
which I use to store JDBC connect strings etc.
What is the proper directory to put this file so the XSLT
extension class can find it? I am using Oracle HTTP Server with
XDK 9.0.

Thanks for the answer, Steve!
Depends on what call you're using in your extension function to
read your properties.Maybe I tried a too simplistic approach. I'm just using this:
Properties props = new Properties();
try {
props.load(new FileInputStream("/foo.properties"));
etc.
This (with the slash) works if the properties file is in the root
directory of the filesystem, but it's a kludge.
If you read your properties as a resource using
getResourceAsStream(), then where the classloader expects to
find your file depends on the resource name that you specify.So maybe I should use getResourceAsStream() then? What if I put
the properties file inside the JAR with the extension classes?
Or is there any way to reference the web root?

Cant resolve class on XSLT Extension

I have XSLT and I am trying to call a java method and I get
java.lang.NullPointerException

Trying even a simple example using java.lang.xxxx gets the same error.

<xsl:template match="/">
<xsl:variable name="x" select="99"/>

<x-hex><xsl:value-of select="Int:toHexString($x)"/></x-hex>
</xsl:template>
</xsl:stylesheet>
This is XDK 9.2.0.6
Thanks in advance.

What is main diff b/w imported Archives and External Defination in IR

What is main diff b/w imported Archives and External Defination in IR

Hi Vijay,
ED-standard schema for describing the message structure.If you have the structure provided to you from some external application you can use it in PI directly without recreating in PI.you can import following formats which are used to describe message schema
WSDL (Web Service Description Language),
XSD (XML Schema Definition Language),
DTDs (Document Type Definitions)
Imported Archives: its used basically for java and xslt mapping where you create the required mapping externally using some tools
(java-eclipse/NWDS .XSLT-stylus studio).You can also implement XSLT and Java mappingsf and save them as archives in the Integration Repository.

Imported Archive not visible

Hi Guru,
I have imported into XI a XSLT Mapping in IMPORTED ARCHIVE; now I have to use thi mapping in my Interface Mapping, but the imported Archive (the XSLT Mapping...) is not visible! How is it possible?
Thanks to all!

hi,
1. Make sure that the XSLT program .zip or jar format.
2. If the mapping program it' not showing then forceble you need to push your interface mapping.
If the mapping program it is not showing mean particular source message particular target message couldn't defind the mapping program..this is not complesary any mapping program we can push through forceble .

Venu.

What is the Use of Imported Archives in Mapping Objects

Hi All,
What is the Use of Imported Archives in Mapping Objects ( IR )
Regards
Vamsi

Hi Vamsi,
When we are doing JAVA , XSLT mappings we have to do import archievs
after developing the JAva mapping in NWDS and create jar file come back to IR under imported archieves we will import the jar file.
Similarly XSLT als make the zip and import under imported archieves
Also when we have any java packages ,import it under archieves and make them to use in UDF

How to upload into import archive

How to import the XSL mapping and JCO LOOK UPS int to import archive archive
should i import java file or class file in look ups part , what abt the XSLT mappimg part, then i want to test the mapping part will you please tell me how to copy the already existing interface so that i can test the mapping part without distrubing it
thanking you
sridhar

Hi,
To test the XSLT Mapping:
-Zip the .xslt file and import the zip into Improted Archive
-Then create the new Interface Mapping or you can copy old Interface Mapping by right clicking on the Interface Mapping where you required to use XSLT mapping
btw, if you are using xslt or java mapping, you need to just use this in the Interface Mapping.
-In interface mapping, you can see the drop down list to select type of mapping and proceed further. It will direct you .
Hope this helps,
Rgds,

Problem with imported archives

Hi all,
I have created Message mappings(this I have to delete once get the sucess),Interface mapping.I need to use XSLT mapping so I copied the Message mapping output to XSLT file Organization_2_PSTCS_Department_XSLT.xslt and when Imported into imported archieves.
When I try to use this mapping I am getting the message as in SUB .Alternatively if i use the message mapping I am getting sucess.
Please let me know what is the problem.
Thanks,
Srini

Hi,
>>>>>>I need to use XSLT mapping so I copied the Message mapping output to XSLT file Organization_2_PSTCS_Department_XSLT.xslt and when Imported into imported archieves.
you copied the output ? (you mean the result of message mapping?)
this has no sense as message mapping has nothing to do with
xslt mappings
you need to create your xslt mapping yourself and then import it
you cannot create xslt mapping from message mapping
