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.

Adapter Module .ear file deployed

Hi All,
I have an adapter module deployed long back on my dev server.
I want to retrive the same file from dev and deploy in on Quality server.
Can you let me know the path where this .ear file will be present on the SAP XI server.
Thx in advance
Ravijeet

Hi Ravijeet,
We run under i5/OS (unix like) but I found my deployed Adapter Module under:
DX1 is the instance name.
sap.com is the vendor specified in the EJB module.
EOLConvertBean is my adapter module
/usr/sap/dx1/DVEBMGS70/j2ee/cluster/apps/sap.com/EOLConvertBeanEAR
/usr/sap/dx1/DVEBMGS70/j2ee/cluster/apps/sap.com/EOLConvertBeanEAR/EJBContainer/applicationjars/EOLConvertBean.jar
Hope it helps.

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.

> strFileName = msg.getMessageProperty("http://sap.com/xi/XI/System/File","FileName");
in PI 7.1 you can use:
strFileName = msg.getMessageProperty(new MessagePropertyKey("FileName","http://sap.com/xi/XI/System/File"));
Note that property name and namspace come in different order. I almost got mad until I noticed

SAP JRA in Adapter module

We are developing an Adapter module for "File Sender Adapter" and in that we have a requirement to call an RFC. We are trying to use SAP JRA (Java Resource Adapter) for doing this as we do not want to hard code the password in the module by using direct JCO connections.
Using JRA we are able to invoke RFC in our adapter module but the message payload does not go to the next module (Standard module) in the chain. We identified that as soon as we get the connection handle using statement:
Connection connection = connectionfactory.getConnection();
message is not going to next module in the chain. We are also not getting any error or exception anywhere. It is just that the message is not getting processed. Any help or idea would be appreciated.
Regards

Hi Amol
I was not able to this today as I do not having authorization in our development system for exposing RFC as webservice and waiting for the authorization.
I want to know if I expose the RFC as webservice in development server, will it be transported via normal ABAP transport procedure in the landscape (will this require any change in config etc.) or I need to expose it separately in different server.

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

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">

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

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

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.
