Need documentation about "Model Driven Development within SAP Netweaver"

Hi All,
in my dissertation there is a topic called "Model Driven Development within SAP Netweaver" and I am looking for documentation (literature) pointing on this.
I'd prefer internet sources since I don't have time to order a book anymore.
Thanks, Johannes

Visual Composer as Modelling Tool
Models designed in Visual Composer can be deployed to run in one or more technology engines, including SAP HTML/B and Flex. The same model can be deployed to more than one environment, although not all components and controls are fully supported in each. Visual Composer implements a proprietary XML-based Visual Composer Language as its source code for creating the models. Only at deployment is the model actually compiled into the executable code required by the selected UI technology. The result is a model once run
anywhere capability.The models that you build in Visual Composer are generated in Generic Modeling Language (GML) code. To deploy your application to a portal, the GML code
must be compiled into a language supported by the portal. During compilation, warnings and possible errors may be discovered, enabling you to check the model validity. The compiled content is deployed directly to the portal, in the runtimeenvironment that you select.In runtime, transactional content can run through HTML/B and Flex, while
analytic content which may require a more animated environment may run through Flex. The models deployed by Visual Composer to the portal include runtime metadata, which is stored with the model in the PCD and exported in the business package, for delivery to customers.

Question about Model Driven over RTMPS configuration

I am testing model driven development features these days and encountered a problem:
When I used RTMP channel to retrieve data from the server, everything works fine, however when I tried to use RTMPS channel, I got following error:
Could not initialize DataService.
Missing or invalid configuration for destinations: ["CodeModel.Code"]
the CodeModel is the model I created by using the modler under Flash Builder4, and it simply include one table called Code. I can retrieve data, update and delete data with this model over RTMP channel, but not over RTMPS channel.
I set up my RTMPS channel by creating a self-signed certificate and installed it in the trusted area of the browser, then I referenced the keystore file in the service-config.xml, here is the snap of my configuration:
<channel-definition id="my-rtmps" class="mx.messaging.channels.SecureRTMPChannel">
        <endpoint url="rtmps://{server.name}:2099"
          class="flex.messaging.endpoints.SecureRTMPEndpoint"/>
        <properties>
            <idle-timeout-minutes>30</idle-timeout-minutes>
             <keystore-file>D:/tomcat.store</keystore-file>
            <keystore-password>password</keystore-password>
        </properties>
</channel-definition>
following is the server side log when I tried to retrieve data from server over RTMPS channel:

The server side log did not show any exceptions, I am wondering is there any other settings that I need to pre-config in order to make my app run over the RTMPS channel?
Any help will be appreciated!

The problem is solved. The error message is due to the default channel was set to RTMP in my data-management-config.xml file. That's why modifing the application level default channel does not work. After I changed it to RTMPS, it worked.
One more thing to make sure though, if I want to use both of the RTMP channel and RTMPS channel in my app (not for fail over) , I have to create at least two models right? Also do I need to change the default channel in data-management-config.xml if the model I am about to deploy expects different channel than previous models?

Question about model driven dev and RDS configuring

I am testing the model driven development that is brought up by Flash Builder4 and LCDS3 recently, and it went pretty well. However i've noticed that the configuration of the RDS for development mode is not recommanded for a production environment.
My first quetion is can I simply disable the RDS on the server when I want to deploy my app to a production environment and still be able to use all of the features such as data management service and remote service etc.? I've tried to do so but it gave me a 404 page. I felt it was a little bit confusing when you know you DO have a html template located in the right location. If RDS can be disabled without interfering the functionality of the app, where can I find a doc to follow?
My second question is if the RDS is a must, then how to configure the security setting? I knew some of the requirements by visiting this url:http://help.adobe.com/en_US/LiveCycleDataServicesES/3.1/Developing/WS6822bf3ec1c7b2e9-30fb 9b22126b9ca84aa-8000.html,
however, when I followed the steps and test it, I got a 400 error in FB4 RDS configuration page.
Since I am testing this under Tomcat 5.5, I am not sure where should I put the flex-tomcat-common.jar and flex-tomcat-server.jar file in, cause the dir structure of Tomcat 5.5 is a little bit different than that of Tomcat 6.0. Then I put these files under both of the tomcat 5.5\common\lib folder and the tomcat 5.5\server\lib folder. I've doubled checked the the catalina.properties file which is located under tomcat5.5\conf folder and I see the following environment param has been there : ${catalina.home}/common/lib/*.jar.
The other configuration I made that differs from the doc was: I put <valve classname="flex.messaging.security.TomcatValve"></valve> into the context.xml, which is under the folder Tomcat 5.5/conf. Since I put the Resource definition in the same file, I guess this should not be the problem.
Does anyone has any successful experience on setting this up?
Any hint will be appreciated.

Thanks for the quick reply.
I solved my first problem, it was because I accidentally commented out part of the RDS configuration and left the servlet-mapping part un-commented. After I generate all the client and server codes and re-deploy them to the environment, I finally got my running demo with RDS disabled.
For the second problem, I am still stucking in. I've tried to switch to the Tomcat 6.0 and follow both of the LCDS installation doc and the LCDS3.1_using doc. None could work me out. I constantly get the error message said that "The RDS server was successfully contacted, but your security credentials were invalid". So after struggling a whole day, I found the following statement, which is appeared in the ColdFusion configuraton doc:"Note: If you are using ColdFusion MX 7 or earlier, the message "The RDS server was successfully contacted, but your security credentials were invalid," appears. The message indicates that the password was not validated, even if it is correct. Click OK to close the message. ". That's interesting cause it seems it was exact the situation I was encountered. However, in my case, ignoring the error message does not give me a successful RDS connection.
For your information, I am pasting the configurations I had on my machine and maybe some ppl could give me a correction.

How to Fill Sorted Data with model Driven Development

Hello
I am using model driven development. I am using getAll in the Fill method. But the results are not returned sorted by some field that I am interested in. How do I tell the Fill to sort it by some field. Is there some annotation that I can provided in the model...
thanks
RK

You should be able to achieve what you want with an explicit criteria filter on your entity.
In the Modeler Design view, select your entity and add a filter. You'll see that there is a an "Order By" field in the Properties view.
Enter the value you want there and then save and redeploy your model. When you don't enter anything in the "Criteria" field, you create a getAll fill.
Here's an example of an entity created with this type of filter; it is sorted by price in ascending order:
<entity name="Product" persistent="true">
<annotation name="ServerProperties" ServerType="LCDS"/>
<annotation name="DMS" Table="PRODUCT"/>
<annotation name="RDS" introspectedColumns="PRODUCTID,DESCRIPTION,PRICE,PRODUCTNAME"/>
<annotation name="VisualModeler" width="115" height="110" x="364" y="203"/>
<id name="productid" type="integer">
<annotation name="DMS" ColumnName="PRODUCTID"/>
</id>
<property name="description" type="string" length="255">
<annotation name="DMS" ColumnName="DESCRIPTION"/>
</property>
<property name="price" type="float">
<annotation name="DMS" ColumnName="PRICE"/>
</property>
<property name="productname" type="string" length="255">
<annotation name="DMS" ColumnName="PRODUCTNAME"/>
</property>
<filter name="MyFill" order="price ASC"/>
</entity>

Development Consultant SAP NetWeaver 2004

Hi,
I am a certified ABAP consultant with Certification 2000. I would like to upgrade my certification to Development Consultant SAP NetWeaver 2004 - Application Development Focus ABAP. Does anyone know where I can find study material for the certification exam?
Thanks.

Hello Corina
I have taken both exams. Even at the Netweaver exam (6.40) which I passed 10 month ago a big portion of the questions were dealing with "basic" stuff. I you have not taken any exams yet I like to mention that you do not have to write down any answers but it is a multiple-choice test:
- either a single answer is correct (then you will see radio-buttons at each possible answer) or
- serveral answers are correct (checkboxes)
Sample question: "Which modifications are possible with sorted internal tables?" => Of course you cannot append to such a table but must insert your entries.
So, if you have a firm stand on BC430 (ABAP Dictionary), have developed quite a lot (-> BC400 basics of ABAP) and have some general understanding of ABAP-OO (BC401) you will be on the safe side. Also, have a general knowledge of the SAP Technology (guess corresponding to BC050) like the client-server technology.
Official documents like the BC401 documents cannot be shared because SAP would not allow this. In any case, you will find plenty of information in the SAP online help.
Finally, I highly recommend the weblog <a href="/people/thomas.jung3/blog/2005/05/15/abap-46c-to-640-delta-training 46C to 640 Delta Training"</a> by Thomas Jung. You need not to know these topics in detail, yet they might be useful for some questions.

Can Adobe forms developed under SAP NetWeaver be used in SAP Rel. 4.7 ?

Hello,
I was asked by a customer whether it is possible to use an adobe form in SAP Release 4.7 which was developed in SAP NetWeaver or not.

Hello,
I think the key component you need for Adobe forms is ADS (Adobe document services) which you will only get with Netweaver.
Please see the following link for SAP recommended environments for Adobe forms:

SAP NetWeaver Developer Workplace & SAP NetWeaver Developer Studio

Hi All
1. What is the difference between SAP NetWeaver Developer Workplace & SAP NetWeaver Developer Studio. Which area JDI (Java Developer Infrastructure) fall in.
2. Is SAP NetWeaver Developer Workplace & SAP NetWeaver Developer Studio
are tool for Enterprise Portal development/customizing Only or can you use also use to customize XI/BW/SRM etc..applications.
3. Is SAP NetWeaver Developer Workplace & SAP NetWeaver Developer Studio are replacement of old ABAP programming
Thanks everyone.

Julio,
To answer your third question, No, NetWeaver Developer Studio (NDS) isn't to replace ABAP or ABAP workbench. NDS helps in creating Java based applications to compliment with the ABAP programs and enable them accessible via the Enterprise Portal. ABAP would stay to be the primary development language for SAP systems. The newest version of NetWeaver software also come with an option of ABAP stack where in you can develop web based applications (accessible via the portal) using ABAP

Kiran

MAM development on SAP NetWeaver Mobile 7.1?

Hello world
I did notice that SAP has released SAP NetWeaver Mobile 7.1. I was of course very curious if this would (finally) make MAM25 developments possible in the new SAP NetWeaver (Mobile ) Developer Studio 7.1, because the old SAP NetWeaver Developer Studio 7.0 is based on Eclipse 2.X while the new one is based on Eclipse 3.3 (which has some advantages compared to Eclipse 2.X).
So I did download SAP NetWeaver Developer Studio 7.1 and SAP NetWeaver Mobile 7.1, and installed both of them on my system. I was positively surprised when I noticed a Mobile Infrastructure perspective. So I did download our customized MAM25 source code from the CVS server and I tried to let it compile and run on SAP NetWeaver Mobile Developer Studio 7.1.
Compiling was not a problem: after including some required JAR files, the code did compile successfully, however when trying to export the project, it seemed that the JSP files were not compiled, however I did put the tick mark at the Add JSP as compiled classes option. In my NetWeaver Developer, a folder $jsp was created, but with nothing inside. And in the generated WAR-file, I couldn't find any compiled JSP file as well...
In the 7.0 version, a file called mam25.jar was created and putted into the lib folder in the war archive file, which contained all the class files. This file was not created with version 7.1.
When trying to run the MAM from within NetWeaver Mobile Developer Studio 7.1, I did get the following exception when launching:
java.lang.NoClassDefFoundError: com/sap/tc/mobile/cfs/startup/Startup
Caused by: java.lang.ClassNotFoundException: com.sap.tc.mobile.cfs.startup.Startup
Is there anyone who can tell me whether or not SAP NetWeaver Mobile Developer studio 7.1 is able to compile, generate and run the MAM25 source? If not, why is there a perspective Mobile Infrastructure included?
If it is compatible, does anyone have an idea why it didn't work with me?
Thanks for your help!
Best regards,
Diederik

Hi all,
First of all, thanks for all the information!
I think there is a little misunderstanding, or maybe I am wrong
SAP NetWeaver is the web-application you can use to analyze, administrate, etc... your mobile applications?
I am actually talking about the SAP NetWeaver Developer Studio 7.1, which is in fact just an extended Eclipse environment. There is some kind of mobile update pack which you can find here: [SAP NetWeaver Mobile 7.1 SP3|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/c0846cb5-59ec-2a10-46a2-cff9cd9b8fc3]
My question was if you can maintain and develop in JAVA your MAM25 application with this version of the Netweaver Developer Studio? I did notice a perspective Mobile Infrastructure as in version 7.0, and I can compile the JAVA code, but I can't run the application (see error in original posting) and it seems that no JAVA files are generated from the JSP files.
I guess it is just a matter of making the plugins compatible for Eclipse 3.X, because the plugin system of Eclipse 2.X is not compatible with the plugin system of Eclipse 3.X. But because of the Mobile Infrastructure perspective that I did notice, I was thinking that this was done. But this seems not to be the case, or I did do something wrong...
So the only question is: can I use SAP NetWeaver Developer Studio 7.1 (aka Eclipse 3.X) to develop in JAVA the MAM25 application?
Thanks for the help!
