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.

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.

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.

Import com.sap.aii.mappingtool.* show error in PI 7.1 adapter module

Hi
Experts,
i have an adapter module for 7.0 and i am trying to replicate the same for PI 7.1 in 7.1 NWDS.
i have made the required changes as mentioned in stefan's blog :/people/stefan.grube/blog/2008/12/11/adjust-your-pi-70-adapter-modules-for-pi-71-in-15-minutes
but import com.sap.aii.mappingtool.tf7.rt.Container; shows error , do we need to inlcude any jar file for this :
i am using this module to rename file name (in case of pick and place scenario forwithot IR configuration)
getMessageProperty and setmessageProperty is getting deprecated.(striked off)
strFileName = msg.getMessageProperty("http://sap.com/xi/XI/System/File","FileName");
Regards,
Srinivas

> 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

Another SOAP Sender adapter "com.sap.aii.af.mp.module.ModuleException" erro

I am working on a synchronous scenario SOAP <-> XI <-> RFC.
This worked fine, when I run it without SOAP adapter, direct via XI Pipeline.
Now I want to use the SOAP sender adapter, but get the error as described below this post.
As this is a real new XI installation, some patches or updates might be required to make it work. Or some adapter modules ?
Any suggestions on how to solve this problem will be rewarded.
What worries me a bit is the line " " in the error description.
Extra info: I use SoapSonar as a test webservice client. The error is the message as received in te test client.

Obtaining BAPI Parameters in Adapter Module

Hi All
I am using JRA way for obtaining BAPI parameters in Adapter Modules.
Could someone provide me some guidance on the same.
Which method in java will be used in retreving the value from BAPI inside module.(Example: Filename)
and method for passing the same to BAPI using adapter module
Regards
Abhishek Mahajan

Hi ,

https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/ad09cd07-0a01-0010-93a9-933e247d3ba4
Which service pack you are working on ?
If you are on SP14 then you need not create a wrapper, you can use standar SAP feature to do this.
http://help.sap.com/saphelp_nw04/helpdata/en/c8/e80440a832e369e10000000a155106/content.htm
Commit Control for Individual BAPI Calls
If you want to use this communication channel to call BAPIs as remote-enabled function modules that change data in the database, set the indicator.
If executed successfully, the transaction is written to the database by calling the function module BAPI_TRANSACTION_COMMIT explicitly. If an error occurs, the transaction is rolled back by BAPI_TRANSACTION_ROLLBACK.
If your working on service pack <SP14 then refer the link below...this will help you in creating a wrapper..

Access BAPIs Using the SAP Java Resource Adapter

Hi experts,
Can someone tell me how to Access BAPIs Using the SAP Java Resource Adapter?

hi Shweta,
Please refer the step by step procedure:
1. Start the deploy tool of the SAP J2EE Application Server with the DeployTool.bat in the directory //<SAP J2EE Engine Installation Directory/.../j2ee/deploying.
2. Choose Project → New Project and enter a name for the new project.
3. Click on the Deployer tab.
4. From the menu path, choose Deploy → EAR → Load Module and select the sapjra.rar file.
5. For the newly created node sapjra.rar, choose Server Settings → Identity Subjects and select Caller Impersonation as authentication type, so that the J2EE user data is used to log on to the ABAP system.
6. Make sure that the J2EE Application Server is running. Connect to the J2EE Application Server with Deploy → Connect.
7. Deploy the sapjra.rar using the menu Deploy → Deployment → Deploy Module.
8. Enter SAPJRADemo as application name and start the application.
9. Close the deploy tool.
10. Start the Visual Administrator again.
11. Select the Cluster tab and switch to <Server Node> → Services → Connector Container.
12. Click on the Runtime tab and choose sap.com/SAPJRADemo → eis/SAPJRADemoFactory.
13. Choose Managed Connection Factory → Properties. On this page, you need to specify the logon data for the ABAP system. There is already some dummy data visible in the property list if no real system data has been specified so far.
14. To change the value of a property, select the property in the list, change the value underneath it, and add the changes using the Add button. At the end, do not forget to save all changes by pressing the button Save Changes. The user configured for the SAP JRA must be the user authorized to read metadata of function modules.

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.

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.
