User defined modules in File Adapters

Hi SapAll.
i just want to know how and in what situations we will use user defined modules in the file communication channels under Module Tab.
can any body explain me briefly with a real time scenarios.
regards.
Varma.

hi,
user defined modules or custom adapter modules can be used to do few thing which can't be done by standard SAP modules, typical example in file adapter would be:
Reading/ Writing excel file through file adapter

The sequence of system modules & user-defined modules

Hi Experts,
can u help me clear about the execution sequence about system modules , user-defined modules & the adapter of XI/PI ??
I presume the sequence is first adapter ,second own modules, finally system modules at the sender end.
and the sequence at the receiver end is first own modules , second system modules ,third adapter.
im right?
by the way, how about the sequence when the scenario is be setted to synchronization, specially the sequence of the
response.
thx in advance.
Brian.

1. for async sender/receiver adapters, you use modules before the standard adapter module.
2. for sync sender/receiver adapters, you can wither use modules before the standard adapter module (they will affect the request message) or after the adapter module (affecting the response message).

User Defined Module Processor

Hi folks;
I had a query that can we access a file placed on netweaver server(copy the content or delete a particular file) using a User defined Module,added to file adapter

hi
To explain you more clearly our scenario
We have a sender folder in which we have xyz.xml(Source file) and xyz.PDF (Attachment) .
while configuring the file adapter we are archiving both these files to a folder
With the help of user modules we need a abc.xml file to be picked from some other folder and placed to our sender folder
For this functionality to be added to our file adapter we have to write a code
my e mail add is [email protected]

[SOLVED] Loading user-defined modules [FAIL]

Since the linux upgrade that rolled out on Nov 9, I have encountered an error during boot that says loading user-defined modules [FAIL]. I read a post mentioning the problem being related to the /boot dir being on a separate partition (https://bbs.archlinux.org/viewtopic.php?id=129970). Mine is not on a separate partition, so no booting to a live disk will fix that problem for me. Another post mentions the problem causing loss of USB support (https://bbs.archlinux.org/viewtopic.php?id=130030) which is, as of yet, unresolved. I For all the people upgrading to linux3.1.1 with no problems, do you know what my problem would be?
I have tried upgrading 3 times but each time it kills my wireless support completely. All else seems to be working fine.
Does anyone know what is causing this? or how to fix it or work around it? I updated my mirrorlist and ran pacman -Syyu but this problem is still there 2 weeks later. I've been running pacman -U /var/cache/pacman/pkg/linux-3.0.7* and rebooting after every system update.
Please help.
Thanks.

Thanks. I didn't realize I had to get a new driver every time. I've gone through several kernel upgrades so far and haven't had any problems. That fixed it, though.

How to add/restore user-defined presets (.cst files)?

Having recently fixed my corrupted install of GB2 with a clean install of GB3, I want to restore all my customized twiddles. Restoring all my self-made and 3rd-party loops was as easy as dragging them to the Loop Browser. I'm less sure about how to restore things like my self-made Real Instrument presets and so forth (all those fiddly .cst files).
From my old GB2 install, I archived the whole /Library/Application Support/GarageBand/Instrument Library/ tree, so all my presets and everything are saved in their correct locations under that path. So, for example, I can drill on down to my archived [...]/Instrument Library/Plug-In Settings/Amp Simulation/ and find my old user-defined .cst presets.
When I drag them to the appropriate [...]/Instrument Library/Plug-In Settings/Amp Simulation/ location in the support files tree of my new GB 3 installation, I get a warning that I need authorization. This is presumably a permissions issue, and if I authorize it by typing in my admin password, my old .cst files will be where I want them.
But I have a nagging worry about whether they'll be correctly recognized by GarageBand when I then restart it. Is there some other better/different way to get my old .cst presets recognized in the new installation? Will they not appear because they haven't been indexed or something? I want to be sure of the best way to do this so I don't mess up my shiny new GB3 installation
Cheers,

iBook G4 Mac OS X (10.4.6)

Making the backup archive before futzing around is certainly a good idea And, yes, there is quite a bunch of Instrument Library stuff new for GB3 that wasn't there in my GB2! (I look forward to messing with it
When trying to copy my .cst and .pst files, when I clicked the Authenticate button on the you-ain't-got-permissions dialog box that came up, nothing happened. So I twiddled the permissions for the whole Instrument Library via Get Info, and then moved my stuff. That worked, though of course, Repair Permissions in Disk Utility won't fix them back now because the files aren't on the Start-Up disk. But, hopefully, it shouldn't really matter!
For some reason, it still wouldn't recognize the added .cst and .pst files until I'd trashed the GB .plist/.cs and restarted, but now it seems to be fine. It was a bit slow to respond when I tested things be selecting some of my newly restored presets, but perhaps that's because it was still indexing. I haven't really checked it all through thoroughly to make sure things sound all right, but the signs are good
Cheers,
Carl

User defined path, assigned file name

I would like enable the user to define the directory where the file created will be saved but keep the naming convention I implemented the same. I set up a small, and yes crude, program to test out the functionality of the code and its just not working out. Any suggestions? I'm, using Lab View 6.1.

Try replacing the File Dialog function with a Build Pth function.
It looks like you want to append two parts of path together to build a
complete path. The File dialog does not do this, it just lets the user
select a path. You can then use that path to build the complete path
with your filename using the Build Path function.

Exception related to user defined module in sap xi ????

I developed one userdefined module after configuring that i am getting the below exception, can any body tell where exactly the problem
      com.sap.aii.af.ra.ms.api.RecoverableException,
Thanks,
Madhusudhan.

Madhusudana,
Well...I would in that case suggest you to put debug statements in your code. For this you would need to carry out certain steps which are :
1. In NWDS , create a new file in the META-INF folder of Enterprise Project. The name of the file should be log-configuration.xml.Paste the following content in this file
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log-configuration SYSTEM "log-configuration.dtd">
<log-configuration>
<log-formatters>

<log-formatter
name="trc"
pattern="%26d %150l [%t] %10s: %m"
type="TraceFormatter"/>
</log-formatters>
<log-destinations>

<log-destination
count="5"
effective-severity="DEBUG"
limit="2000000"
name="sample.trc"
pattern="./log/applications/sample/default.trc"
type="FileLog">
<formatter-ref
name="trc"/>
</log-destination>
</log-destinations>
<log-controllers>

<log-controller
effective-severity="DEBUG"
name="sample">
<associated-destinations>
<destination-ref
association-type="LOG"
name="sample.trc"/>
</associated-destinations>
</log-controller>

</log-controllers>
</log-configuration>
2. In your process method, add following statement
AuditMessageKey auditMKey =
               new AuditMessageKey(message.getMessageId(), AuditDirection.INBOUND);
          Audit.addAuditLogEntry(
               auditMKey,
               AuditLogStatus.SUCCESS,
               "CustomModule :: process method started");
This would send the statement "CustomModule :: process method started" to the Audit Log of XI server and you would be in a position to see upto which step your code is executing sucessfully. Audit log can be viewed at
http://<host>:<port>/MessagingSystem/monitor/monitor.jsp. you need to know the message ID for your transaction in this case.
Hope this helps.

User Defined Function Error - Can't find function

Hi All,
Version: 11.1.1.4
I created a user defined function and added it to one of my BPEL Processes. I can see the function in JDeveloper and can compile the project without issue. We placed the jar file out on the SOA Server following the oracle user defined function examples. After placing the file out on weblogic I was able to successfully deploy the project.
Oracle Deployment Steps:
To deploy user-defined functions to runtime:
1. Copy the user-defined function JAR files to BEA_Home/user_projects/domains/domain_name/lib or a subdirectory of lib. Where domain_name is the name of the Oracle WebLogic Server domain (for example, soainfra).
2. Restart the Oracle WebLogic Server.However, when I try to run the composite application I get the below error. I am not really sure why it can't find the Function? The jar is out on the server and the jar was added to the project?
Error:
Non Recoverable System Fault :
<bpelFault><faultType>0</faultType><subLanguageExecutionFault xmlns="http://schemas.oracle.com/bpel/extension"><part name="summary"><summary>XPath expression failed to execute. An error occurs while processing the XPath expression; the expression is pnl:GetManager(string(bpws:getVariableData('inputVariable','payload','/client:process/client:input'))). The XPath expression failed to execute; the reason was: Function 'GetManager' not found.. Check the detailed root cause described in the exception message text and verify that the XPath query is correct. </summary></part><part name="code"><code>XPathExecutionError</code></part></subLanguageExecutionFault></bpelFault>Any suggestions would be greatly appreciated!
Thanks,

try putting the jar location explicitly in weblogic server's classpath i.e. add BEA_Home/user_projects/domains/domain_name/lib to wls classpath and restart server.

Cannot comile user defined classes

Hello i have a problem on compiling user defined classes .
example
file x.java
public class x{
file y.java
import x;
public class y{
I first compile x.java and everything is OK .
Then i compile y.java and the compiler gives the folowing
y.java:2: '.' expected
import y
I have tried to put the classes on a package and added the folowing line yo each file
import /home/bill/test
Then i puted the java files on that dir
and compiled with
javac -classpath /home/bill/test y.java
AGAIN THE SAME
y.java:2: '.' expected
import y
WHAT I DO WRONG PLEASE HELP!!!!!!!!!!!!

1. Since J2SDK 1.4, you can not import classes that are in the default (or unnamed) package. You are getting the error because the compiler expects something after y like y.*;
2. You do not need to import classes that are in the same package, and all classes in the default package are in the same package.
In your case, your classes are in the default package so remove the import statement.

Driving processing with user defined rules

Hi,
I am looking for some examples of user defined rules for file processing.
So I have a file loaded in to the application in a staging table, user will want to define rules to process the data and then an output will be created.
Very vague question I know but has anyone got any examples where they did something similar which might help?
Thanks.

Just so you know, this is not necessarily the best way to do what you're asking. It does get the job done however.
If you inspect the code it's basically just a bunch of string concatenation operations based on the presence or absence of each of the input parameters. Pretty much what you were asking about.

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.

How to deploy jar file for use within mapping user-defined fcn

Hi all,
I have a java class I'd like to called from a mapping user-defined function.
Here's what I've done (but hasn't worked)
1. Added 'package com.<mycompany>.xi.util.base64 to the source class file and compiled it.
2. Created a sda with a plain provider.xml file, i.e. no references were made to any other library files.
3. Deployed the sda to the xi 3.0 j2ee server successfully using SDM.
4. Under the Visual Admin tool, I see that the library was deployed successfully.
5. In the import text box in the user-defined function (design time), I enter com.<mycompany>.xi.util.base64.*.
A syntax check returns an error indicating the package could not be found.
Can anyone give me pointers as to how I can get this working?
Thanks,
--jtb

Hey James,
No! That's not the right way!
What you have done is for accessing external JMS & JDBC drivers in their corresponding adapters. For the access inside a mapping user defined function, it's enough if you import the jar files.
Look at this blog and you will be very clear!

Error in User defined function for dynamic file naming

Hi,
While creating User Defined function with this following code for dynamic fieldname
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return ourSourceFileName;
which options should i select for cache Value, Context, Queue
for Augument , what name shd i mention.
Regards,
Varun

Hi Varun,
I guess I have answered a similar question just a few minutes before on very similar post from you. Just pasting the same here .................
Are you trying to access the ASMA values from the SOAP header of the XI message for the source file name?
First of all you need to Set the Sender File Adapter for Set ASMA and then file name. So it will work fine when you actually run the scenario end to end.
But in the mapping tool when you test the mapping - there is not message header updated with the actual source filename - and whenever you try to read the FileName attribute in the message header from the UDF - it cannot find the object and returns a NullPointerException.
I would suuggest for your mapping tool testing to be successful, have a check in the java code for null values,
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
If (ourSourceFileName != null)
Return ourSourceFileName;
Return "NoFileName.txt";
Let us know if this works.
