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.

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.

Joschi

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.

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.

No CAF Dictionary for developing CAS

Hi there,
I am trying to get familiar with CAF. So I downloaded the Sneak Preview version (Full Java Edition
SP15) and tried to complete one of the tutorials.
I created a new project, and a new Entity Service. That worked fine. Then the tutorial tells me to add an attribute to that service and tried to assign the type com.sap.caf.core.shortText to that attribute as the tutorial says. But I couldn't select that type from the simpleType-window because the node com.sap.caf.core wasn't there.
So i tried to generate the service-code (without any attributes). This didn't work either because the Developer Studio couldn't find any class from the package com.sap.caf.
I tried to find the classes in the Netweaver Developer Studio file-system (c:\...\sap\jdt\eclipse\plugins) and i found the classes. But that could not be way to solve the problem.
Can anyone help me, please!

Hi Aliaksei,
thanks! That hint worked. There were several wrong entries in that .classpath-file.
After searching inside several jar-files i figured out that the following entries were missing:
In the Dictionary-Project:
<classpathentry kind="lib" path="C:/Programme/SAP/JDT/eclipse/plugins/com.sap.tc.ap/comp/CAF/DCs/sap.com/caf/core/dict/_comp/gen/default/public/types_compilation/lib/java/sap.comcafcoredicttypes_compilation.jar"/>
In the EJB-Project:
<classpathentry kind="lib" path="C:/Programme/SAP/JDT/eclipse/plugins/com.sap.tc.ap/comp/CAF/DCs/sap.com/caf/runtime/impl/_comp/gen/default/public/CAFRuntimeAPI/lib/java/sap.comcafruntimeimplCAFRuntimeAPI.jar"/>
<classpathentry kind="lib" path="C:/Programme/SAP/JDT/eclipse/plugins/com.sap.tc.ap/comp/CAF/DCs/sap.com/caf/runtime/security/_comp/gen/default/public/ejbjar/lib/java/sap.comcafruntime~security.jar"/>
There are no more errors in the task-view now, so i am hoping that the CAS will compile and can be deployed to the server.
Thanks again!

Is it possible to deploy this missing caf-ear component supplementary?

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...

Workflow start with caf gp application

Hi Experts,
I am on nw2004s, erp2005, ep7.0 sp11.
ESS Business Package has one application developed on CAF GP called Life and Work Events. In this, there is a process "Birth/Adoption". This process has blocks, actions, callable objects (web dynpro java based). The standard application does not trigger a workflow. I have finished one task through portal like changing family data and i run the transaction SWEL. I see some events on Business OBjecttype: FAMILY, EVENT: CREATE, CHANGED.
I do not know by this time these events are created, the data is already written to database. Please clarify me.
when the user does this on portal, it should trigger a workflow (like send an email to HR Administrator) before the values are written to DataBase.
When HR admin does two actions; Approve or Reject. when approved, data will be written to data base.
what are the basic steps that I should follow to complete this process?
Regards,

I am designing the workflow process for family data changes through the Life and Work Events GP applications.
1. i created a task with Object Type FAMILY and method: APPROVE.
I went ahead and tried to define the triggering events (FAMILY- Created, Change). I tried to activate: the system throws an error: binding for event is incorrect-no activation possible.
any body help me why I get this error?
I solved this problem by myself.

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,

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

CAF Core Metadata checker

does any of you have a way or tool to check / fix metadata consistency of CAF Core based projects in developer studio ?
SAP has one but it does not seem released to the public. Meanwhile many of us are having recurring troubles with metadata getting corrupted that causes waste of time.

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

CAF Core vs CAF GP

Basically, I need to learn the following, correct?
1. Oracle database fundamentals
2. PL/SQL
3. Using Forms Developer
Anything else?

Oracle announced the retirement the Oracle Certified Professional Application Developer track for Oracle Developer Release 2, effective July 31, 2002.
After July 31st, the 3 core exams will no longer be available:
