What is Composite Application Services?

Dear Experts
What is Composite Application Services? What is it's use?
How can I create one?
Please give some sample scenarios so that I can try working it out.
Regards
Aparnna

Hi Aparnna,
You should use CAS or SAP Netweaver Composite Application Framework when you want to develop a composite application based on Netweaver platform. By composite application means an user-centric application based on a business process which is composed by services provided by backend legacy or enterprise systems. In CAF/CAS perspective in NWDS you can create a CAF core project and define your business entities with its corresponding access and lifecycle methods. These methods can be exposed as web services to be consumed by the CAF UI like Web Dynpro or Visual Composer.
For more information on CAF please refer the following links:

Exception in calling a web service from a composite application service

Hi,
I have created a composite application service with external service as a web service. My web service is deployed on localhost as well as I am running my composite application service in localhost. When i try to test the application service, I get the exception
com.sap.caf.mp.base.exception.InvocationException: Invalid parameters
The exception happens in MPConnector.java 'process' method where I am calling the execute operation on the service.
I have tried testing this through Service Browser as well as creating a callable object on the Application service and testing the callable object.
I am using the NWDS 7.0.06 version
and EP installed on my machine is the Sneak Preview 7.0 sp 7
Will appreciate all help in this regard.
Thanks,
Prachi

Hi Navneet,
I have verified the input/output parameters. They are simple types. All are Strings. Nothing really complex there.
I have the Service Exceptions added already.
And definitely the permissions are disabled but still this isn't working.
Any more clues might be helpful.
Thanks,
Prachi

Error when trying to create a Composite Application Services project

Hi Experts,
I am facing a problem while trying to create a project using NWDS 7.0 SP 13
New Development Component Project-> Composite Application Services
then pressing finish, it throws an error as follows
"Generation can not completed due to one or more error"
Reason :
Errors occurred during code generation
Warning :
EAR-META-INF generation failed : null
Plz help me to solve this
Thanks in advance,
John

Hi John,
It looks like there might be issue with CAF services related plugins. Check if there are any errors in log file under metadata folder of your workspace.Try deleting the metadata folder & restart the NWDS or start in a new workspace.
I feel if the issue persists, it is a bug & you can raise an OSS ticket.
Kind Regards,

Problem when Creating Project (Composite Application Services) in NWDS

I've seen a few posts regarding this but I don't feel as if any real solution was given.
I just installed Netweaver Developer Studio (7.0.15) with the current JDK/JRE (1.6.0_07). When trying to create a new Composite Application Services project within the Studio, using the new project wizard, I get an error: Problem when Creating Project.
I get the EJB Module and Dictionary to create within my navigator with no problems, however, during the creation of the metadata, the error occurs. I do have the metadata folder appear within the navigator, but nothing in it. None of the other three items are created.
I have tried the attempt at deleting the metadata folder within my workspace directory and trying again but the same exact result occurs.
Is there any other solution out there for this problem besides attempting to find older versions of NWDS, etc. that are more "stable"?
Thank you!

Durga,
Very simple but effective solution.
I had tried uninstalling / re-installing NWDS with no effect but uninstalling / re-installing NWDS AND all java related products on my machine did work.
Note: For anyone else with this issue in the future. I installed the Java SDK / JRE 1.4.2_18 with NWDS 7.0.15 in case this is also a possible issue with versions.
Thanks, Durga!

Composite Application Services perspective not visible

Hi ,
i am working with Netweaver 7.1. I am not able to view Composite Application Services perspective in my NWDS. is there any licence issue or plug problem?
Kavita

Hi,
I think you have not installed required features from updite site(Local download directory) propperly after installation of your IDE.
In that case you have update your IDE through Software installation update option of Help menu.
The procedure will be mentioned in the start page of Software setup file(SAPNWCE71Trial_DevStudioSAPNWCE71Trial_DevStudio).
[This |perspectives not visible in NWDS 7.1 ehp1;thread is useful for you.

Parameter's name of Composite Application Service's operation

Hi All,
When we define a operation of Composite Application Service, we just simply add it from operation tag, and add the input & output parameters by choosing the attribute type and click the add-as-input button. The added parameter would be something like arg0, arg1, etc.
Is it possible possible to change these parameter's name into semantic word instead of these meaningless ones?
Thanks

Hi,
Select the operation parameters and open the properties view below. There you can change the name of the parameters.

BO-findAll operation to use in Application service

Hi Experts,
I am new to CAF development, i have requirement that i need to read the CAF database records based on the Custom key created. It returns a object with the entire record( sometimes multiple records) so how to read those records from the object(return value) and display them one by one.
It would be helpful if you could send some sample code.
thanks
ketan

Hi Ketan,
You can implement findAll or findById in application service. First while defining the operations set the output parameter to be a structure which contains that BO(You create yourself a complex structure for it-there you can set cardinality).
Then in the application service under that operation using the service Bean of the BO access the Bo's corresponding methods(either findById or findAll). Get that output and set it in the output parmeter and return it.
public com.caf.types.FindAllAmendmentsResMsg findAllAmendments(
               @javax.jws.WebParam(name="inputParameter1")
               com.hcl.xapps.ipr.caf.types.FindAllAmendmentsReqMsg inputParameter1) {
          FindAllAmendmentsResMsg response = new FindAllAmendmentsResMsg();
          try {
               List<Amendment> amendmentList = new ArrayList<Amendment>();
               amendmentList = (List<Amendment>) this.getAmendmentService().findAll();
               response.setAmendmentList(amendmentList);
          } catch (CAFFindException cfe) {
          return response;
The above is an example for findAll.
Hope it helps you

Using Composite Application Framework to deliver global HR applications

Hello,
I'm new to Composite applications but have experience with Web development and Web services.
Our business case is the following:
- Working on HR applications
- The customer is a group made of 3 companies.
- We have 2 separate back-end system, one global for the group and one dedicated the company
- Some HR business processes need to be performed on both the global and the company system. Exemple: Hire of an employee. Depending on the company the employee will work for, some data needs to be created on the company system and on the global system
I believe this can be achieved with Composite Application Framework. I guess, front-end application has to be build (using Composite Designer?). What I don't know is what type of technology is used to build the front-end application?
Finally, the idea behind this is to replace the current solution: multiple interfaces between the group system and the company system.
Thanks for your feedback, any suggestion or tip would be most than welcome!
Laurent

While I was searching the web for some answers, I found out you can create web based composite applications using web dynpros for Java.
Is it possible to do so with web dynpro for ABAP? I guess we can build an abap web dynpro application that connects to different web services from different back-ends to retrieve and update data. Can anyone confirm this?
Thanks,
Laurent

Step by Step to access custom Java API in Application Service.

Hi Experts,
I have a situation to access the custom Java API in CAF. The Java API fetches the data from MDM. I need to get the data from that API and and use it in the CAF Application Service layer? Is there a way to access the JAVA API in the Application Service Layer? If so please do help me out. Step by Step solution would be appreciated.
thanks in advance.
Regards
Ketan

Hi Ketan,
You can do it in two ways.
1. You can create your own custom class in the ejbmodule which you can see in the Navigator view.
2. You can have a ear having the custom class. This ear will be in a separate DC and CAF will have dependency to it.

How to access XI_AF_MSG table in Composite Application Framework Java Code

Hi Experts,
I've no knowledge about PI. In one of my projects, I need access the XI_AF_MSG table of PI through java code in a composite application.
How do I access this table? I've searched this forum for this query but the replies say that any SQL editor can be used to access XI_AF_MSG table. But my question is; How do I get the login details of the database? In the first place, how do I access the underlying database layer of PI? Is there any JAR file which can be used to make the connection?
It would be of great help if any expert on this can give me a detailed reply.
Thanks a lot in advance.
Best Regards,
Nitin

Hi Nitin,
The AFW runs on the J2EE Engine, so this table is in the Java Schema of the database and thus not visible in the ABAP stack. I guess you can use any tool your database provider offers for looking at table contents (e.g. SQLPlus).
Regarding how to access the table please contact you basis administrator they will have access to the tables as they have j2ee_admin login ids and pwds.

Application Services uses other application Services like business Object

Hallo
I use the SAP NetWeaver 7.1 SP3.
One question can i use in the Applcation Service another Application Service (not Business Object)?
The reasons I want to have this possibility:
If I use the external service and I will be exposed as a new Applicaiton Service, thus it can be used by several application Services.
I have put one Application Service A into the dependency of Application Service B... but in code i can not find out the API to lauch to the Application B.
Thanks and Kind Regards
Ping

Thanks
But I can not find the Object ApplicationServiceALocal
and the code
ApplicationServiceALocal appServiceA = this.getApplicationServiceA();
I can not get it.
Maybe I should after the add dependency Generate Application, buîld Application?
Kind Regards

Error during creation Composite Application Service

Hello!!
In SAP NetWeather Developer Studio we create CAS(Composit Application Service), then we create ENTITY and make GENERATE ALL PROJECT CODE. If CAS is created locally, there are no errors during generation, but if it is created non-locally, an errors occurs with JDO.
1) The project was not built since its classpath is incomplete. Cannot find the class file for javax.jdo.PersistenceManager. Fix the classpath then try rebuilding this project.
2) This compilation unit indirectly references the missing type javax.jdo.PersistenceManager (typically some required class file is referencing a type outside the classpath)
Thank You!!

Hi Vadim,
Please uninstall your NWDS and java and reinstall them.
This may solve your problem.

UCM 11g - how to accessing secured content using open WCM service

Hi All,
Does any one has an idea on how to access the contents that are checked in with security groups as "Secured". If the contents are checked in as "Public" then, we can easily access the same with the following open WCM servervice:l

Hi Donato,
Did you ever get an answer for this issue? I'm trying to get a similar case working and would be curious on how you ended up doing this...
For what I know so far, this may help you:
1) The trigger-EBSProfile requires you to pass th afGuid value, this value, is created automatically by the IPM process, basically, when you click the MA button in EBS, the SOA call to IPM does 2 things:
First, it creates a row in the AFGRANTS table in the WCContent DB, this basically overwrites UCM security and give the user access to the documents, this table has the information of the EBS record (Business Object, and Primary Key) as well as the auto generated afGuid
Second it sends back the URL to WCContent, mainly "/cs/idcplg/_p/min/af/trigger-EBSProfile?IdcService=GET_SEARCH_RESULTS_FORCELOGIN" and passes the afGuid created in the first step, which identifies the EBS record.
So if you need to make direct calls to UCM under the trigger-EBSProfile you will need to manually (custom) add the afGuid and details of the EBS record to the table, the entries in this table get removed automatically based on the dexpirationdate value
2) While the IPM SOA call overwrites the UCM security, if you have implemented your own security structure (assign a different security group to the documents and give the users access to it) you could make calls directly to UCM bypassing the "trigger-EBSProfile"..
for example, in the call you were trying to make originally to DOC_INFO, if you know the dDocName of the document, you can simply call the service as "/cs/idcplg?IdcService=DOC_INFO_BY_NAME&dDocName=POC2001" (I use DOC_INFO_BY_NAME because you need to know the dDocId for DOC_INFO)
You can do the same with other services like checkin/checkout etc, (for checking you will need to pass the additional parameters dfBusinessObejct, dAFBusinessObject and dfApplication to link the document to the EBS record)

Juan Becerra
