Database naming problem in CAF Core

Dear Experts,
I am experiencing a serious problem when testing the NW CE 7.1. I have created two projects with different vendor name while the project name and business object name are the same. I found that they will use the same database table. If I don't pay any attention to the database table name. They will overwrite each other when I deploy the application. I think this is a very dangerous and serious problem.
However, as I am still testing without NWDI in place, will NWDI solve this problem? Please advise. Thanks!
Regards,
Alex

Hi,
Try reading near to the end of this page - http://help.sap.com/saphelp_nwce10/helpdata/en/b9/1cec745b7f4f0c925b8b32ddd3004e/frameset.htm - as a starter for 10.

Problem with CAF Core Exercise

Hello All,
I am performing the CAF exercise I doing it as per the guide How-to-Guide CAF Core however when I am trying to create a Web Service from the CAF Applications I am getting the following error:

Hello Raimund,
Thanks for your reply.
Yes I am executing these components on the discovery server. It's actually part of the exercises that came with the server which is Composite Tool Box.
When I am deploying the application without converting the Application Service to a Web Service everything works fine when I am trying to convert it to a Web Service as required by the Visual Composer part of the exercise, I am able to buld it however when I am deploying it I get the Exception.
Thanks.

Error while creating new employee in CAF Core application

Hi
I am novice to the CAF, this is my first CAF Core application which I have created and deployed in J2EE engine successfully. Its ready for Testing, here I am trying to create a new employee but while saving it, giving error like:-
ERROR. Exception thrown in method createEmployee. The transaction is marked for rollback.: Exception thrown in method create. The transaction is marked for rollback.: com/sap/caf/rt/exception/CAFIllegalAccessException
Anyone can help out me.

Hi Cindy Herrman,
FYI , that check box already unchecked, while setup the employee entity only that Permission check box unchecked, still I am getting same problem.

External WebService call from CAF Core returns Invalid soap message

I am trying to perform the very simple action of calling a WebService from a CAF Core app service.
1. I imported the WS (Axis Web service running on NW 2004s SP9 server) with WSDL (option 2 on import external service page).
2. I then assembled the call in an app service method and invoke it.
3. I made sure to configure the end point for the service and the method using the External Service configuration.
When I execute the CAF core method using a simple Callable Object test client, I get the following error:
com.sap.caf.mp.base.exception.EngineException: Invalid soap message received
 at com.sap.caf.mp.core.data.service.manager.wsdl11.SOAPToMessageValueConverter.processComplexTypeMode(SOAPToMessageValueConverter.java:290)

I have also captured the XML request/reponse trace using tcpmon :

The only problem I can think off is that the transfer-encoding is marked as chunked which is causing the characters '1f3' and '0' to appear after and before the response and that this is causing the app to crash.
192.168.99.120 is the server the hosts the WS. It is also a 2004s SP9 server. The client server that hosts the CAF core service is of the same configuration. 8078 is the port I redirect for tcpmon purposes.
Could anyone shed some light on my problem?
Thanks,
Pratap.

It looks like NW WS client cannot handle Transfer-encoding of chunked even though this is part of HTTP 1.1. What seems to be happening is that the NW WS client is creating a HTTP 1.1 request. The service (axis ws running on NW) seeing this is creating a HTTP 1.1 response w/ chunked encoding. However, the client cannot handle this encoding and barfs. The solution is to change the service to return a HTTP/1.0 response since NW cant handle HTTP 1.1.

Is it possible to deploy this missing caf-ear component supplementary?
I have the strange feelings caf/core/ear is something 7.1 CE only related....
thanks for any hint!

Using XI created Web Service in CAF Core

Hello,
i'm despairing!!!!
For 2 days I'm trying now to get my XI created Web service working in my CAF Core application...the result is depressing.
First of all: the Web service works without any problems when I import the WSDL into "oXygen" tool. I'm generating a request and get the correct result. The message is processed without errors in XI.
I followed the steps described in <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/11669cea-0c01-0010-63b2-b98c35b1b370">Using a Web Service as External Service</a>. I have 2 search values (with option, minValue, maxValue) where I map each minValue to the corresponding external service attribute. But when I test the everything in the ServiceBrowser (with parameters ""), the message is processed in XI but with empty search parameters. This means that my "" values are not transferred via XML to XI.
Maybe I put in incorrect URLs (tutorial part: "Configure external services") for WSDL Description URL and End point URL. Which URLs are the corresponding ones in a WSDL file?
Can anyone help me?
Thanks and regards
Joschi

Hi Andre,
Thanks for your answer, but now I'm a bit confused...why is this tutorial for GP? A Web Service is imported as External Service into a Composite Application Service DC in NWDS and then wrapped by an Entity Service. After deployment the Entity Service is tested with the Service Browser. So I don't see the connection to GP.
The passage with 2 search values is maybe a bit confusing, yes. I will search for materialNumber and salesName (2 search values). And for each my Entity Service operation presents me in the mapping mask three "sub"-parameters: option, minValue, maxValue.
So my question on your question: Why do I have to set the "option" to "=="? I don't need the option for my Web Service. In the tutorial there's also no "option" set. In addition I'm not able to set the "option" in my Entity Service because no coding is allowed. So is the tutorial wrong?
By the way, I already set the "option" to "==" in an extra Application Service (which cals my Entity Servie) and tested it. I created 2 QueryFilters and set "option", "minValue" and "maxValue". But this also doesn't work.
Regards
Joschi

Encapsulating web services in CAF core

Hi,
I am trying to call external services namely web services in caf core. I read the earlier posts and i guess I am missing out on something.
1. what is the difference between encapsulating external service as entity service VS application service. For example, I am trying to call the PurchaseOrderVendorAddress_WSD webservice. It takes vendorID and purchaseorderID as input and returns vendor address. What should I use and why?
2. I checked out CAF core tutorial. It talks about encapsulating RFC as application service. Is it same for web service? I mean can I assume the same approach is valid for web service
Many thnx,
Mayukh

did you follow the tutorial "81 Using a Web Service as External Service (Service)"?
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/11669cea-0c01-0010-63b2-b98c35b1b370
you can't be lost after that. otherwise you're in big trouble my friend...

CAF core archiving

Hi,
I am looking at options to archive my CAF code database. We are still in a early phase of development. However wanted to check on the options that we have to archive the data in the CAF core as the database size grows over years. Any help/ links are highly appreciated.
Thanks & Regards,
Keerti

CAF Core is always there in the IDE by default. You can use any of its Entity/BO/App service in your project.
Thanks,
Dipankar

CAF Core

In NW2004s SR2 installation documen, page 128 "Performing Post-Installation Steps for Composite Application Framework Core (CAF Core)"
In SLD
1. In the System Landscape Directory (SLD), create a new project.
2. Create a new software component (SC) to be developed.
3. Create software components of the build plug-ins for the dependent development component(DC). They are:
Archive Names
BI-MMR, CAF-KM, EPBC2, SAP_JTECHS,
BI_UDI, CAF-UM, EP-PSERV, SAP_PRT,

Problem:
1-How can I create project in PI/XI SLD?
2-Some dependent components are not available in SLD.
3-is CAF setting necessary for PI/XI?
Thanks.

Got the same question...
Additional /Background Information on this chapter is helpfull

CAF CORE COLLECTION_ASPECT_KEY error

I have a simple entity "Approver" with attribute functions (string) and contacts (String), cardinality 0:n for both.
I build UI object based on Object Editor pattern for this Approver Entity service. Also build the UI object based on Relationship Tab patteren for the Approver Functions and Contacts (attributes).
When I test the UI (Object editor pattern based) for entity service. It let me add the record to functions and contacts tab, but when clicked on save returns following error.
Key (or KeyList) [localKey@11e75a9] is no Key (KeyList) of type COLLECTION_ASPECT_KEY_Approver
At one point this was working fine. I tried to recreate the Entity Service, UI pattern objects and now both the functions and contact tabs not working. Can not save the records added in those tabs.
Do I need to do any coding in Entity Service? Is there a documentation that I refer to resolve this error?
SAP has developed CAF-CORE technology, I guess it will be nice if they can really put out good documentation and tutorials with complex examples.
Thanks

Hi ANdre,
I have one entity "Approver"
with following attributes
Attribute Name            Type      Cardinality
id                     String      0..1
name                   String      0..1
functions              String      1..n
hrContacts             String      1..n
I would have idealy like to have recusrive relationship, because User or employee plays different roles, like, assistant, hrContact, approver, supervisor. Employee could be associated with multiple functions. To keep the things simple I am having the functions and hrContacts as field on the entity, idealy would have like to have, reference to another entity.
I guess the problem is with automatic code generated for Entity service and UI patteren. It is expecting something at some place and that's not well documented.
I have another Entity service with similar structure for Vendor entity and all the UI pattern work fine, that including Object Editor and Relationship tab.
Thanks

Database termination Problem

Hi every body ..plz help me on this..
We are facing database termination problem in ECC6 production syste.
Database: Oracle 10.2, O/S: Windows 2003. Spam :27, SP level 13.
Error is:
Errors in file f:\oracle\p02\saptrace\background\p02_ckpt_6520.trc:
ORA-00206: error in writing (block 3, # blocks 1) of control file
ORA-00202: control file: 'D:\ORACLE\P02\ORIGLOGB\CNTRL\CNTRLP02.DBF'
ORA-27072: File I/O error
OSD-04008: WriteFile() failure, unable to write to file
O/S-Error: (OS 33) The process cannot access the file because another process has locked a portion of the file.
When we are performing backup then data base termination occuring freequently.
Give right solution as early as possible.
Thanks,
Nani.

Hi,
Have a look at below snote which actually speaks about the oracle error codes
Snote : 546006
within the Snote it says :-
" If you cannot access a database file (for instance a data file, control file or RedoLog) for whatever reason, an ORA-270xx appears. The actual cause comes from additional error messages (usually in the operating system) that occur on ORA-270xx. "
And as per your last update
" ORA-00206: error in writing (block 3, # blocks 1) of control file
ORA-00202: control file: 'D:\ORACLE\P02\ORIGLOGB\CNTRL\CNTRLP02.DBF' "
i think there is problem accessing the database control file. Hence you are facing the above problem.
I think if you recreate your control file i think, it should resolve the problem.
Hope it will be helpful to resolve your problem.

Immediate HELP in Tomcat 5 to Postgresql 7.4 database connectivity problem

Hi,
I failed to connect Tomcat 5.0.24 with Postgresql
7.4.2. The files created by me and the changes i had
made in the existing files are rates.jsp,
conversionDAO.java, web.xml and server.xml. The error
message on the top of the rest of it was "The value of
useBean class attribute converter.conversionDAO is
invalid". So far I found out that the coding for
database connectivity purpose in conversionDAO.java
cause the error. Another thing is Postgresql jdbc
driver is required to set in the CLASSPATH for the
java file to access the Postgresql database. I don't
know where should I put it in Tomcat for web
application. Anyway, I put it in
$CATALINA_HOME/shared/lib according the book i
refered. I do the database connectivity coding refer
to the Tomcat Kick Start book from Sams Publishing.
Below are the coding involved, please show me the
mistake i had made. Thank you.

Hi Shriraj,
ensure that the installation path is correct. I only put /urs/sap/<SID> and you must put /usr/sap/<SID>/DV***/.
In my case with that the setup returns all in green.
I hope it helps you

SIMPLE Database Design Problem !

Mapping is a big problem for many complex applications.
So what happens if we put all the tables into one table called ENTITY?
I have more than 300 attributeTypes.And there will be lots of null values in the records of that single table as every entityType uses the same table.
Other than wasting space if I put a clustered index on my entityType coloumn in that table.What kind of performance penalties to I get?
Definition of the table
ENTITY
EntityID > uniqueidentifier
EntityType > Tells the entityTypeName
Name >
LastName >
CompanyName > 300 attributeTypes
OppurtunityPeriod >
PS:There is also another table called RELATION that points the relations between entities.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
check the coloumn with WHERE _entityType='PERSON'
as there is is clustered index on entityType...there
is NO performance decrease.
there is also a clustered index on RELATION table on
relationType
when we say WHERE _entityType ='PERSON' or
WHERE relationType='CONTACTMECHANISM'.
it scans the clustered index first.it acts like a
table as it is physically ordered.I was thinking in terms of using several conditions in the same select, such as
WHERE _entityType ='PERSON'
AND LastName LIKE 'A%' In your case you have to use at least two indices, and since your clustered index comes first ...
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Have you ever thought of using constraints in your
modell? How would you realize those?
...in fact we did.We have arranged the generic object
model in an object database.The knowledge information
is held in the object database.So your relational database is used only as a "simple" storage, everything has go through your object database.
But the data schema is held in the RDBMS with code
generation that creates a schema to hold data.If you think that this approach makes sense, why not.
But in able to have a efficent mapping and a good
performance we have thought about building only one
table.The problem is we know we are losing some space
but the thing is harddisk is much cheaper than RAM
and CPU.So our trade off concerated on the storage
cost.But I still wonder if there is a point that I
have missed in terms performance?Just test your approach by using sufficiently data - only you know how many records you have to store in your modell.
PS: it is not wise effective using generic object
models also in object databases as CPU cost is a lot
when u are holding the data.I don't know if I'd have taken your approach - using two database systems to hold data and business logic.
PS2: RDBMS is a value based system where object
databases are identity based.we are trying to be in
the gray area of both worlds.Like I wrote: if your approach works and scales to the required size, why not? I would assume that you did a load test with your approach.
What I would question though is that your discussing a "SIMPLE Database Design" problem. I don't see anything simple in your approach when it comes to implementation.
