Reg Adapter Module in SAP PI 7.11

Hi,
I am trying to develop an Adapter Module using SAP NWDS and I am referring http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c0b39e65-981e-2b10-1c9c-fc3f8e6747fa?quicklink=index&overridelayout=true for the same.
Now I am stuck on page 11 (page 16 of the pdf).
Does the value of Remote interface have to be strictly com.sap.aii.af.lib.mp.module.ModuleRemote (similarly for other parameters)?
Are these values dependent on the Default EJB Package that we use (mentioned on page10). Because the name of my package is com.companyname.adaptermodule and is as per the naming convention that we follow.
Thank you,
Pankaj.

Hi,
Ok. Actually I thought that the names are dependent on the default EJB package-name that we specify in previous step; but now these two do not seem to be related to each other (name-wise)
The question seems to be answered for now. Thanks to Stefan.
Thank you,
Pankaj.

REG : Can we change namespace using any adapter module.

Hi All,
           I was working on the XMLAnonymizerBean adapter module. his module provides us the functinality of changing the prefix of namespace and selecting sprecified modules in the output XML. Now i am stuck with a question ie is there any module that can change the namespace in the output xml. for example :
xmnls : namespace1 to
xmnls : namespace 2.

Hi,
You can use a simple XSLT mapping in Receiver adapter . check this blog
http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=%28J2EE3417100%29ID0975923150DB01234155231841994144End?blog=/pub/wlg/2620
Provide the actual namespace in the bleow code
<?xml version='1.0' ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:p2="provideyournamespace">
     <xsl:template match="/">
                   <xsl:copy-of select="*"/>

Issue in calling Adapter Module

Hi experts,
We have a File -
> IDoc scenario where the file has got fixed length data. The data is in the following format:
Header xdfsdfefefeswefr
Detail dfdkfereorierwer
Detail fdfkjwoeiefiwere
Detail
Trailer erererewoirwoiwe
We do not have any identifier to identify the header, detail and trailer record.
We have gone for custom java adapter module which inserts H, D, T as the first character of each line in the file to identify the Header, Detail and Trailer nodes.
We added a entry for calling the adapter module under the module tab in file sender communciation channel. The EAR for adapter module has been deployed successfully.
But we are unable to call the adapter module at runtime.
The channle log has no indication wrt to the module being called.
We are on SAP XI 3.0 SP17
If any one has faced a similar issue. Please respond and your help would be highly appreciated.
regards,
Younus

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!

Dynamic configuration required in sender file - Adapter Module

Hi Everybody,
I am developing an Adapter Module in the file adapter (sender) using Adapter Specific Message Attributes.
I am using Dynamic configuration inside the Module Process method in the adapter module.
We are getting an error saying Dynamic Configuration cannot be resolved.
Can anybody tell me the package to be used.
Thanks,
Zabiulla

You can access the dynamic configuration in adapter module like this:
Message msg = (Message) inputModuleData.getPrincipalData();
String fileName = msg.getMessageProperty("http://sap.com/xi/XI/System/File", "FileName");
You do not need any addition library besides the adapter module API.
Hope that helps
Stefan

ModuleData.getPrincipalData returns null in the adapter module development

Hi gurus,
i am doing a test on the adapter module development following an article written by William Li:
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0ac06cf-6ee2-2c10-df98-e17430ca5949?QuickLink=index&overridelayout=true
my problem is after the EJB has been deployed, it seems that the return of inputModuleData.getPrincipalData() is always null which makes the program can not get the xml payload from the framework.
the main process of the example has been simplified like this:
     public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          Object           obj = null;
          try {
          obj = inputModuleData.getPrincipalData();
          Message     msg1 = (Message) obj;
                XMLPayload xmlpayload = msg1.getDocument();}
          catch (Exception e) {
               ModuleException me = new ModuleException(e);
               throw me;
          return inputModuleData;
after deployed, i get the following error in the adapter monitor of RWB: (my JNDI is testtest)
17.02.2012 17:13:44.643 Information Send binary file "test8.xml" from FTP server "10.18.48.150:/encrypt_test/", size 206 bytes with QoS EO

whereas if the code has been changed like this:
     public ModuleData process(ModuleContext moduleContext, ModuleData inputModuleData) throws ModuleException {
          Object           obj = null;
          try {
               obj = inputModuleData.getPrincipalData();
               Message     msg1 = (Message) obj;
               if (obj != null )
                    XMLPayload xmlpayload = msg1.getDocument();
          catch (Exception e) {
               ModuleException me = new ModuleException(e);
               throw me;
          return inputModuleData;
the file can be read by the file adapter.
i just quite confused that why the return of the getPrincipalData() is null? where is the problem? thanks
Edited by: Stephen Xue on Feb 17, 2012 5:22 AM

I'm gonna reply to myself here. I changed the processing sequence of the adapter modules in the in the FileSender channel so that my module comes first then CallSapAdapter. Then getPrincipalData() contains the message.
Hope this helps someone else.

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.

Using a different user(other than default PI user) with adapter module

Hi,
We are having a custom adapter module built to interact with a Hardware Security Module(HSM). This custom adapter module by default uses a PI user configured in the system. However, we are not able to pass commands to HSM because of insufficient authorizations to this PI user. Now, we do not exactly know the permissions required for the user to access HSM. We have asked the HSM support team about the same. However, I wanted to explore the possibility of using a different PI user to work with the adapter module and eventually pass commands to HSM.
We have an admin user configured which has all the necessary authorizations. Is it possible to use this admin user created on PI system to work with adapter module so that it passes commands to HSM?
Thanks,
Ravi Desai

We have given the necessary authorizations to PI user.

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 Receiver File Adapter

Hi All,
I am getting file name in the Mapping in my target structure in a field FILENAME and i want to use this field to create a file at the target with the name as the value in FILENAME.
I have to develop this by using Adapter Module.
Note : This can be done by Variable Substitution and Dynamic Configuration UDF.But i want to implement the same by using adapter module.
Can somebody help me out in getting the FILENAME from mapping inside the module process method of module.
Thanks,
Zabi

Try this..
private Map param;
DynamicConfiguration conf = (DynamicConfiguration) param.get(
StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey KEY_FILENAME = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String Filename = conf.get(KEY_FILENAME);[/code]
Thanks

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.
Regards,
Henrique.
