Integrating Flex/Flash in Web Dynpro ABAP(Netweaver 7.0) need info!

Hi all,
I need to embed a flash or a flex object inside a web dynpro abap application.I am working in Netweaver 7.0 and i don't have enhancement pack 1 installed.Is it possible ? If it is possible can anyone please provide me the coding and configuration details.
Thanks,
Saikat

I'm afraid that the SAP supplied integration technology - call FlashIslands - is only available from NetWeaver 7.01 and forward. You could perhaps do some simple integration (very little data transfer) with the iFrame UI element - although the iFrame is deprecated in 7.0 and 7.01, but does return to full support in 7.02. The other option would be to use the NetWeaver Portal or NetWeaver Business Client and have two iViews within the page. One iView would have WDA and the other some external technology (BSP, JSP, etc) to host the Flash/Flex content. Not tight integration, but you could potentially use Portal Eventing to at least communicate events.

Simple: add web dynpro to netweaver developer studio

Hi all,
I downloaded and installed a java version of NetWeaver that has only the developer studio.
is there a package that I can use to add web dynpro ?
or do I have to download another version that has both ?
thanks.

Thanks Valery.
but I don't think web dynpro is installed.
I installed the NetWeaver "Java EE 5 Edition"...
this versin has only the NetWeaver developer studio.

Upload a .xls file in web dynpro abap

Hello,
I want to upload a .xls file into a internal table in web dynpro abap (Netweaver 7.31).
The file is not delimited, is not an csv file.
In my view I have an fileUpload UI Element with the attribute data is un attribute type XSTRING and the following function module are not in my system:
HR_KR_XSTRING_TO_STRING
ALSM_EXCEL_TO_INTERNAL_TABLE
How can I upload the file with this format?.
Thanks in advance.
Xavi

Unless the files are zipped together into one archive file, you have to do them one at a time. Furthermore with the normal browser based fileUpload UI element, you must do them one at a time and the user must manually select each one (browser security limitation).
If you are on 7.01 you can use ACFUpDown to perform multiple file uploads, but there is no file dialog or directory scan so file selection is difficult.
If you are on 7.02 you can use ACFUpdown and it has a multiple file open/save dialog.
If you are on 7.01 you could use FlashIslands to perform the multiple file upload. I have a tutorial and source code sample for this on SCN.
If you are on 7.01 you could also use ACFExecute to run a batch script on the client side that zips all the files and then upload the zip archive.

Web service and web dynpro

Hi,
I am learning about web services in java web dynpro. I follow some tutorial on how to create a web service in a java web dynpro using netweaver developer studio. The tutorial works (I think) because in the picture of my local development, I can see the web dynpro component and the model representing the web service. In the web dynpro explorer view I can see the model has been created and the method/service that can be called. But now I don't know how to go on calling these services by the web dynpro methods; can anybody please explain me or post me a link with a tutorial for this (that I did not find). Thanks in advance

Problem in creating a web dynpro application in netweaver developer studio.

Hi,
I have installed Netweaver developer studio. while creating a webdynpro project by selecting File->new->project, It doesn't display "web dynpro" option in the project wizard dailogue box.
Please suggest how to resolve this issue.
Thanks.

Hi Babu,
Make sure following plugin folder
"com.sap.ide.webdynpro.ui_xx.yy.zz(for ex:com.sap.ide.webdynpro.ui_2.0.0)"
exists in your ecclipse root folder (for ex:C:\Program Files\SAP\IDE\IDE70\eclipse\plugins\)
It is responsible for the UI selection elements in File->New Project->WebDynpro selection.
If it's not there you will have to copy it. check also other webdypro plugins installed correctly. these plugins comes with default installation of SAP WEBAS.
if all plugins not installed then redo the whole installation but at the same time make sure all plugins installed correctly.
reward points if usefull
Thanks

BW SEM-BPS API functions from a Web Dynpro project in Netweaver

Hi,
Rather than using the standard Web Interface Builder in BW SEM-BPS (3.1B), we have to use SAP Netweaver to create a Web Dynpro project which accesses all the API_SEMBPS functions, such as GETDATA, SETDATA, FUNCTION_EXECUTE etc. Has anyone done this before? If so, do you have any examples, hints?
Regards,
Linda Lee

Hello Linda,
let me add some more remarks on this topic from the BW-BPS development perspective:
I completely agree with Marc's statement.
Thechnically it is possible to build a planning application UI on top of the BW-BPS API functions and we have some customers that are live with such a solution. However, I would recommend this only in 2 cases
1. You need to create a tightly integrated application with BPS being only one part of several other components (including transactional UI, e.g. running against a CRM system).
2. You prefer a UI technology that is not provided by SAP (e.g. Java Swing based).
In all other cases, I would say that one should stick to the Web Interface created with Web interface Builder, mainly for cost reasons. If this tool does not fulfill all your needs there are several possibilities to enhance and extend the generated web interfaces by custom specific coding (see also several How-To guides in this area; e.g. "How to integrate a BEx Web Template into a BPS Web interface").
Another possibility is to loosly couple several web UIs with the help of the portal.
To my knowledge, it is not true that BSP web technology will be obsolete shortly.
In general, I would always prefer a tool supported, model driven approach compared to a heavy custom coding. This is also in sync with SAPs general strategy to a more pattern based approach to create UIs.

Problem following Web Dynpro tutorial in NetWeaver CE 7.1

Hi all,
I have followed a training at the SAP Training Centre in Belgium, and back from this training I installed the NetWeaver CE 7.1 on my computer.
I have followed the "Developing your first Web Dynpro application" tutorial step-by-step, I have compiled it and deployed it on the server, but I'm having trouble when trying to run this "Welcome" project: I get an error:
500   Internal Server Error

Any idea of what causes this problem?

I have found the problem: the server only supports JDK 5 and I was compiling with JDK 6. I have changed the compiler version and now it works fine!

Use of Web Dynpro ABAP as UI in SAP NetWeaver BPM?

Hello,
Have anybody heard of any plans by SAP to support SAP Web Dynpro ABAP as another option for the UI in SAP NeWeaver BPM?
As SAP now delivers some Web Dynpro ABAP UI:s as part of EHP:s etc it would be good to be able to reuse these in SAP NetWeaver BPM.
All input is welcome.
Thanks for your help and support,

i heard it can be expected in 7.3.

Is abap web dynpro is a netweaver product?

Dear experts,
is abap web dynro is a netweaver product? ..i wonder why is it categorized under application server in sdn forums can anyone explian..
in addition to abap i am willing to learn abap web dynpro.how would be the prospectes of abap web dynpro in the us market ...or do u suggest any other hot topic to learn?..please feel free to comment on my idea and kindly suggest me a better option if my idea is not ideal....
i am not into java till now so i am not willing to learn java web dynpro..
please suggest a better option so that i can use my abap skills to the fullest..
thanks in advance.

Hi Ramu,
Yes, ABAP Web dynpro is a Netweaver product. It cums with mySAP suite.
This is the hot technology in the market and if you are not a JAVA guy then you must go with ABAP Web dynpro.
Basically with the help of ABAP Web dynpro we develope custom products for the client. this is UI based technology and one of best option for "ABAPers" .
For Web dynpro ABAP you will require SAP ECC 6.0 onwards and WAS 7.0
is a must. It has very good future propspects as this is best UI technology.
In web dynpro ABAP we follow MVC(Model View Controller) architecture.
In this object oriented ABAP is used to provide background functionality. Here, your ABAP skills can be utilized to the fullest. Programming in web dynpro ABAP is different than conventional ABAP programming. Here we strictly follow MVC architecture in terms of controller interface. Also there are many wizards available so that we can directly pick the code from wizards.
e.g We can call BAPI through a service call in web dynpro application. Thus automatically backgroud code for BAPI execution will be generated.
To start with Web dynpro ABAP you can try following tutorial:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a282c952-0801-0010-1eb5-87953e036712
You can start with tutorials and all. There are around six tutorials in SDN library.

WEB DYNPRO ABAP IN NETWEAVER 04

Hi to all
When, in my system, I view System / Status, I view that in component versions appear "Netweaver 04".
In this version: I can develop web dynpro for abap ???
Thank you by the information
Regards
Dario Rodriguez.

Hi Dario!
You need SAP Web AS 7.00. SAP NetWeaver 04 is SAP Web AS 6.40.
Thus with your current system you cannot create WDA systems.

NetWeaver, Web Dynpro, WebAS, J2EE enigine, BSP : putting it all together

Hello Friends,
I am new to the developing environment of Web Dynpro. I just need a confirmation on my understanding. Please go through the following abstract and reply with a yes or changes if you dont agree.
Web dynpro is a component of SAP NetWeaver, which also offers many other components such as XI, MI, MDM and BI. All put together NetWeaver provides people, business as well as information intergration. Web Dynpro in itself offers an easy way to develop highly interactive web pages through the MVC architecture. The coding or the meta data is in Java and hence a JDK needs to be installed on the local machine for its compilation. For running it needs to be deployed on the J2EE engine on the Web Application server. The project object gets a URL and accessing this URL displays the web application developed.
Am I correct, till here ? If yes, then BSP initially used for making such web applications holds portability issues unlike Web Dynpro which can be used to develop applications in Java or ABAP, hence the reason why BSP is running off the road and Web DynPro is getting into the picture.
Thanx for yor patience.

Hi Shiv,
first of all, welcome at SDN.
> I am new to the developing environment of Web Dynpro.
No problem, each one of us has been a newbie at the beginning.
> I just need a confirmation on my understanding.
> Please go through the following abstract and reply

> Web dynpro is a component of SAP NetWeaver,
No, Web Dynpro is basically a programming model and SAP's strategic approach for developing highly interactive business applications (it's not really or only a web framework, even if it's used mostly in conjunction with Web browser clients). The Web Dynpro runtime is part of the Web Application Server (until NetWeaver '05 available for Java only, followed by the ABAP runtime). So Web Dynpro is an integrated part of the application platform of SAP NetWeaver, but not a standalone component.

Ok so far.

The metadata is independant from possible target runtimes. At the moment, the metadata is used to generate Java classes only, but this is not mandatory. In case of the Web application server for Java, you need a JDK to run the server itself and as a logical consequence each kind of application hosted by the server (including Web Dynpro apps).
> For running it needs to be deployed
> on the J2EE engine on the Web Application server. The

Nearly correct. In fact, each Web Dynpro application is represented by an URL. A Web Dynpro project can contain multiple applications, so there might be multiple URLs for different applications contained in a single WD project.

Roughly spoken, BSPs are for the ABAP "world" what JSPs are for the Java world. You'll always need an ABAP environment to run BSPs as you'll always need a Java runtime to run JSPs. Portability is limited in both cases to the corresponding basic runtime environment. But, as already stated, this is not really the case for Web Dynpro, since it abstracts the information needed to build the UIs in a manner which is generally independant from the target runtime environment.

You are welcome.
Hope that helps.
