Hi
Adding Wiki as well

https://www.sdn.sap.com/irj/scn/wiki?path=/display/snippets/change%252bpayload%252bin%252badapter%252bmodule
These all are advance concepts.
I think the basic adapter module guide you should try first

Adapter module to enhance File adapter

Hey guys
i need a small clarification regarding adapter modules.
is it possible via adapter modules to enhance the File adapter to such an extent that it can deliver files to two separate systems in separate landscapes.
i know i can design one more receiver determination and can also use Run OS command options,but modules in general give better performance compared to others so just wan't to explore a little bit more about them.
Thanx
Aamir

Hey Aamir,
yeah, they do take a lot of resources, but that's how XI was built to work.
What you're trying to do is a workaround and may not get support from SAP.
If I have understood right, you still wanna maintain the endpoint connection data in the communication channels but want to acces them directly without going through the technical routing pipeline, is that so?
If that's it, I'm sorry but I cannot help you any further.
The only way I know of accessing adapters without going throught technical routing is by using lookup API (RFC, JDBC, Soap) but it is not intended for endpoint scenarios (insert, update etc), mainly for simple read (lookups).
If maintaining the connection data outside adapters is not a concern, you could try to create the connections directly in Java code, inside java proxies.

Adapter Module Filename in File Receiver Channel

Hi All,
is it possible to set the Filename in File Receiver Adapter from Adapter Module?
I know that it is possible to read the data
Channel ch = new Channel(moduleContext.getChannelID());
path = ch.getValueAsString("file.targetDir");
I Need to set the filename in Adapter Module, using of Payload is not possible because Payload is not xml.
Dynamic Parameters in Message Header is not possible because it is an multi mapping process an i need dynamic Filename for each Part
payload after mapping is like
MainDocument
SubMainDocument
MainDocument
SubMainDocument
i need special Name for each SubMainDocument in FileReceiverAdapter
regards
ralf

Hello Stefan,
interface mapping is an mapping like this:
outbound_interface => Inbound_Interface1
                             => Inbound_Interface2
                            => Inbound_Interface3
in sxmb_moni this looks like this
Soap_Header
Soap_Body
Payloads
     =>MainDocument ( application/xml )
    => SubMainDocument ( text/xml )
     =>MainDocument ( application/xml )
    => SubMainDocument ( text/xml )
First SubMainElement is routing to FileReceiverAdapeter A   where Filename has to be like "NameA%nr%"
second SubMainElement is routing to FileReceiverAdapeter B   where Filename has to be like "NameB%nr%"
%nr% is som value from the Payload.
Payload is not xml because using of Conversion Argent!!
I Think there is only one Dynamic in Header for all subelements, i have test it!

SAP PI crashes because of Custom Adapter module

Hi,
We are facing a strange problem. We have deployed a custom adapter module developed in java which accesses a Hardware Security Module(HSM) and uses the keys in HSM to digitally sign our data. Now, when I use particular methods in this code and deploy it on PI server, the server crashes while testing this out. As soon as I run the channel having this adapter module, PI server becomes unavailable. It restarts on its own after a few minutes.
One of the reasons I identified to be causing this issue is the signing mechanism used in code. When I used a mechanism that was not supported or not correct, it crashed the server. If i corrected it, it worked fine. I found no other thing in my code causing this behaviour apart from this mechanism. But I am still not able to understand how a single method in a code can cause the whole server to crash. Has anybody here faced such a problem? Any pointers would be appreciated.
We are using SAP PI 7.31 java only installation.
Thanks,
Ravi Desai

Hi Ravi
1. To check if it is a memory issue. Once you start the channel, check the memory usage in nwa. Check if the memory is increasing once the channel is started.
2. Add debug statements to print logs in default traces at as many places as possible. Since your code is not reaching the Catch block, using the debug statement you can reach the line in the code which is causing this issue.

How to access Payload in XI Adapter Module

Hello,
I have to enhance a adapter module in xi very urgently. Target is to access a node of the XML payload and retrieve the corresponding value.
This is how my document looks like:
<mt_test>
 <element1>
 <> </>
 </element1>
 <element2>
 <LOG_NO>4711 </LOG_NO>
 <element2>
</mt_test>
I need now access the element <LOG_NO>. This can only appear one time in the whole xml document. My code that I did so far (inside the process method) to retrieve this element is like this:
XMLPayload xmlpayload = msg.getDocument();
 DocumentBuilderFactory factory = null;
 factory = DocumentBuilderFactory.newInstance();
 DocumentBuilder builder = factory.newDocumentBuilder();
 Document document = builder.parse ((InputStream)xmlpayload.getInputStream());
 Element rootNode = document.getDocumentElement();
<and now I have no clue anymore:-/>
May you give me an example how to access the node <LOG_NO> and save the corresponding value in a String variable?
I would be really thankful.
Greetings and thanks in advance,
Tobias

Hi,
>>>found no solution with PI Standard Import to support FTP inside the Adapter Module
why would you? file adapter supports FTP - so you don't need it
>>>In order to use FTP library, is there any standard library available or supported by SUN.
you can use any java ftp client available on google

Setting the charset from an adapter module

Hi folks,
I'm trying to set the charset encoding of a payload using an adapter module (I know there is a TextCodepageConverterBean, but I want to set the charset for a message that hasn't one yet). The problem is probably more clear using an example.
I output a UTF-8 flat string from my message mapping to the adapter framework (mail adapter in my case). Afterwards I want to convert this UTF-8 string to an ISO-8859 encoding with the TextCodepageConverterBean. But if I set the charset using the setContentType() function of my TextPayload object the information gets cut away. I'm using the format
setContentType("text/plain;charset=utf-8;name=Test.txt")
. But everything after the first semicolon is dropped. Setting the charset using the MessageTransformBean works, but I want to avoid this by all means, as I need to set the mime type from the adapter module.
This is running on NW2004 with SP 16 and the latest patch.
Any idea, why the MessageTransformBean works and not the setContentType call?

This bug will be fixed with SP20.
Regards
Stefan

Adapter Module for Sender File Adapter to access a Flat file

Hi,
We have a scenario where the source is a flat file.I want to develop an Adapter Module to make a small change to every line in the Flat file.
Now how do we read a flat file in the Adapter Module?Coz the flat file will be converted to XML file by the Standard Adapter Module of the File adapter.
Please help me out with this.
Thank you,
Anu.

Hi Anu,
If you are not using Content Conversion option Standard Adapter Module does not convert the Flat file to XML .
You can directly access the payload as it is in flat file in the Adapter Module and make changes.
Use the Standard classes ModuleData & moduleContext to fetch the Payload.

Adapter Module Error in PI 7.1

Hi,
I have built an adapter module which has been successfully deployed on PI 7.1 using JSPM, but in communication channel monitoring it is giving below error.
Error: com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Object not found in lookup of UserModuleTestEjb
In Module tab of communication channel I have passed Bean name, which works fine for other Adapter Module but strangely its not working for this one.
I have also passed JNDI name which is same as EJB bean name. I have tried several other combinations like below none is working.

PI 7.1 Adapter Module - meaning of VERSION_ID and serialVersionUID?

Hi!
I am currently developing my first PI Adapter Module. In SAP sample coding GetHostName I find the following declarations and I ask me what's the meaning and/or purpose of these declarations:
public static final String VERSION_ID = "$Id://tc/aii/30_REL/src/_adapters/_sample/java/user/module/GetHostName.java#1 $";
satic final long serialVersionUID = 7435850550539048631L;
And additionally how I have to declare these two variables for my adapter module ... This comes true especially for VERSION_ID, because serialVersionUID can be generated by NWDS using quick fix feature. It then declares such a variable ...
Thanxs for any hint in advance!
Regards,
Volker

Hi Pavel,
public - this is the visibility modifier (it means that the body method can be call by any outside method)
static - the method is a static instance of the class. Not sure what exactly it does though.
final indicates that the value of the variable won't change - in other words, a variable who's value can't be modified after it is declared.
Use public final static String when you want to create a String that belongs to the class (no instance necessary to use it), and that won't change, for instance when you want to define a Stringconstant that will be available to all instances of the class, and to other objects using the class, depending on the access modifier:
public final static String MY_CONSTANT = "SomeValue"; // ... in some other code, possibly in another object, use the constant: if (input.equals(MyClass.MY_CONSTANT)
All the variables are implicitly public static final in a Java Interface.
Is it a good coding practice to use public static final in constant variable although it is declared inside an Interface.
For example :
public interface TestInterface{ public static final String EX_CONSTANT = "ABC"; public static final int EX_INT_CONSTANT = 5; public static final double EX_DOUBLE = "5.0"; public static final Integer EX_INTEGER = 10; }

File Adapter Module - Help

Hi
For a file adapter I had enabled the option Archieve File in my communication channel. So the system will put the file in the archieve folder after it is read. My requirement is to check if the file already exits in the archieve folder or not. Any means of checking it? or shud i make use of adapter modules? If yes kindly point some helpful tips on the same.
Kindly fwd any useful doc to [email protected]

prabhu

Prabhu,
The os command in the file adapter should exists in the XI server only.
Whatever command you provide in the Adapter will result in the SID+"ADM" user id exectuing this command at the oS level of your XI server.
So this script should exist on the XI server.
Now, if the archive directory is on the FTP server you will have to connect to the FTP server from the script and check if the file exists and then do the needful.
Check this blog out for executing Scripts on file adapters,

Receiver File Adapter Module processor issue

Hello all,
I have deployed (using SDM) a specific module for one of my file communication channel.
In MDT, I have the following error :
Exceptions survenues pour Adapter Framework : Object not found in lookup of Module0001
La diffusion du message vers l'application via File_http://sap.com/xi/XI/System a échoué en raison de : com.sap.aii.af.ra.ms.api.RecoverableException: Object not found in lookup of Module0001.: com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Object not found in lookup of Module0001.
Where can be the source of this problem ?
Thanks a lot

Jean
Also check if the "JNDI" name that you have specified in the Receiver Adapter module
excluding localejbs matches the deployed name in the "J2ee Aministartor Deploy service.
for example if you have
localejbs/sap.com/BeanName
you should have
the service deployed under
/sap.com/BeanName
