BSP, Webdynpro, Java - Pros / Cons

In the past I made programs using BSP and ABAP. I read a lot of webdynpros and know about the advantages comparing to BSP. But are there also disadvantes?
And what's about the Java technology? I read a lot about the Java technology using SAP. But now a customer asked me to explain why he should use Netweaver with the J2EE-engine.
Is it possible to give me some pros and cons for
a) Java
b) Webdynpro
comparing to the development of BSP-pages with ABAP(Objects)?

First of all another major "difference" between Webdynpro and BSP/JSP beside the UI control is the fact that Webdynpro is always stateful. BSP/JSP have the advantage of being able to program stateful/stateless (or switch between the two). Stateless applications can be very useful when creating internet facing highly scalable applications. However when creating business transactions for a smaller group of users, stateful is acceptable.
Now to ABAP vs. Java. One real world advantage that ABAP has over Java currently is that nearly all the backend business data and logic is contained on the ABAP side of the world. Although you can access this logic and data with Java, ABAP obviously has an easier time doing so. Look at ABAP WebDynpro for instance. If you are creating a WDA component on ECC 6.0 you excellent built in functionality for Value Help. You also can just use Open SQL in your Model Class and avoid any complications that might come from Adaptive RFC. I'm not saying that there is anything wrong with the Java tools. Adaptive RFC is actually quite impressive. However ABAP has the simple advantage of being closer to the application data/logic. Although SAP is working hard to bring the java Development and Transport environment up to the same level as the ABAP world, it is hard to ignore the close relationship between ABAP and the underlying Busines Logic. ESA enablement will help fill that gap in the future, but can't close it all together.
However none of the gaps that I discussed are insurmountable. I think the final decision does come back to what programming language are you and your group most comfortable working in and supporting. In the long term you will create better applications by leveraging the skills sets that you have than trying to force yourself into a environment that you/your group isn't comfortable with.

Portal Eventing in WebDynpro Java Pros and Cons

Does anyone have a link to an article that discusses th epros and cons of using portal eventing between dynpro development components between iViews rather than using one larger web dynpro application. I am clear that reuse can be an issue if you don't make each view t's own development component but I also find portal eventing to be very lacking. What do others think about on this issue and is that an SAP recommendation?

Please read the restriction section.
I will make much more sense if we need a high degree of data interchange between WDP components, to use context mapping and thus internal WDP calls rather than portal eventing.

Your opinion on: BSP or Java Webdynpro or ABAP Webdynpro?

Could you please give me your opinion on the business scenario we have here:
We are implementing SRM 4.0 with backend R/3 4.6C, WAS 6.4 and Portal 6.0. SRM has its typical shopping cart applications mainly for procurement and the workflow trail displaying the approval. The client wants us to build a few custom forms on the web frontend of SRM (or may be in Portal). The idea is to store these forms and display when needed with the status info just like a shopping cart.
Now the requirements for these forms are as follows:
1. These forms will have multiple fields which need to have the F4 kind of help. (the F4 options will reside in SRM or R/3)
2. The form should have some kind of a ALV grid (autoexpanding feature) which will allow the user to put in multiple line items so that they could submit more items on one form.
3. Users need to be able to attach a spreadsheet to the form which should not be editable once the form is submitted. The attached spreadsheet should be stored. (We are planning on using Archivelink Filenet for this)
4. Upon submission, a workflow will be kicked off as per the defined Org structure for approval of the form.
5. After submission, the user should be able to go and view the approval status of the form and also print the summary of the values that he entered in the form. (may be a smartform could be provided for this)
We looked at different options to accomplish this task:
BSP:
Creating BSP pages and giving access as links to the user on the webfrontend of SRM. Now, if we go the BSP route, we need to develop in SRM as the R/3 4.6 c does not have BSP development capabilities. If we take this approach, I am not sure if all the above requirements (specially like attaching spreadhseets) will be met with BSP pages.
SAP Webdynpro Java:
It seems that the Webdynpro is easier to use because of the graphical tools available. But the only problem if we go this route is that we will have to find a java guy.
SAP Webdynpro ABAP:
We currently have WAS 6.4. As per the documentation, the ABAP Webdynpro development tool is available from NW04s onwards. So, we are still not sure if we could use it. But, we want to push towards upgrading if necessary. Being an old time ABAPer, developing ABAP Webdynpro seems do-able. (i know it may not be that easy).
Last but not the least, DIALOG Program:
Creating a dialog program in R/3 or SRM seems fairly simple. Then, an iview could be created on the portal for this transaction, though at this point I am not sure how a spreadsheet could be attached and stored within a dialog program.
The creation of the workflow may not be that bad after the original form is designed. The graphical display of the approval trail might be difficult, but we might get away with a report for that. For printing the details of the form, I guess I could develop a smartform and put out a button on the screen to print it out in the display view.
Could you please give me your opinion / best approach for accomplishing this task, keeping in mind the complexities of these new dimension products?
Thanks

I would say that all four solutions to solving your tasks are technically feasible. Here are some thoughts that I had however:
First ABAP Webdynpro: it is true that ABAP webdynpro is only available with Netweaver04s. 04S is still in ramp-up which means that only a subset of the customer base is allow to implement it. It will not become generally available until later this year (check the service marketplace for current release estimates). That being said, it probably elimintes WDA as a possiblity for your project unless you are will to wait and to upgrade.
However having worked with WDA for a while it is probably the best tool to custom develop what you describe. It has excellent built-in F4 value help. It also has a damn fine ALV grid implementation. The spreadsheet could be just as simple as file upload in binary or your could try your hand at office integration. Finally for the form you could use Adobe Interactive Forms which also has very nice integration into WDA.
Now to Dialog Programming: You could of course use dialog programming. It seems a little bit of a waste to custom build something so large if WDA is in your near future. There are obvious disadvantages (little OO structure, no MVC, etc). You would have ALV grid, office integration and of course F4 help. You could still use Adobe forms if you implement this on the 640 system. However there are integration points with dialog and Adobe Interactive Forms. You could still use printed forms however. If you did the dialog program on the 640 system, you could use the integrated ITS to expose it to the web. The integrated ITS in my experience has quite nice performance although the look and feel remains just like the SAPGui.
The Java Webdynpro route: Well you hit the nail on the head - if you don't have a Java programmer already and you don't have the bandwidth to invest in learning Java, this can be a problem. The Java Webdynpro environment is quite nice. There are some things I like better than ABAP and some things that ABAP is defintely still better at. However when it comes to heavy integration with an ABAP backend - ABAP Webdynpro is still the way to go. Java Webdynpro does have a help feature (OVS), but it isn't "for free" or nearly as nice as the ABAP Webdynpro (perhaps it will get there some day). That is one of the major advantages of WDA - its closeness to the business data brings several framework advantages like F4 and field help. WebDynpro Java in 640 also doesn't have an ALV grid implementation. I am sure that this is something both environments will eventually have, but right now ABAP has the advantage. On the other hand, Webdynpro Java has equal support when it comes to office integration, file upload, and Adobe Forms support. You would have a more difficult time integration SmartForms however.
Finally we come to BSP. Honestly if I were in your position I would probably choose BSP (unless you could wait for the ABAP Webdynpro upgrade). You could build a nice MVC OO application using BSP (stateful or stateless). The BSP product is mature and quite well documented thanks to SDN. You have the BSP Extensions which when used in Design2003 use the Unified Renderer. That means that your output will look nearly identical to the same UI elements in Webdynpro. Also BSP supports portal integration (session management, eventing, and themes).
The downside to BSP is that it isn't a full framework (also one of its advantages). You can insert all your own html and javascript (unlike webdynpro). But this also means that SAP doesn't delivery as many framework services. For instance there is no ALV or Value Help. There is no Office Integration or Adobe Forms integration. There is some farily good Smart Forms integration. Now the upside- many people have already hit these limitations and overcame them. In the weblogs on SDN and in a certain SAP Press book (cough, cough) you will find out of the box solutions for many of these problems. You can find ready to use solutions for Adobe Integration, Office Integration (using Microsoft Office Web Controls), and F4 help. It will mean investing a little more time up front to get this "home grown framework" up and running - but it is perfectly feasible.
There is a learning curve to all these new technologies however. This sounds like an abmious project. I wouldn't want to try and tackle this project in any of these technologies if I was new to them. With Webdynpro or BSP - consider giving yourself time to learn the environment and cut your teeth on some demo apps before jumping into such a huge development.

Webdynpro java and oracle DB connection..

Hi,
I have a good knowledge of WD (web dynpro java) projects having ECC as backend as i have done lot of projects where ECC is backend and WD JAVA is front end.
but in my new project i have wd java as front end but my backend is oracle DB. I want to know how to create/setup connection betwen webdynpro java and oracle DB, how to proceed on this ? wat all settings I have to do in VA (visual admin) and all.
please let me know how to proceed on this. Any document/tutorial on this will be very helpful..

Hi Rahul,
Create a DataSource to the oracle db in Visual Admin, give the datasource an alias name and connect to the db from WebDynpro by calling the alias name.
These document might be useful:

Thanks!!!

Hi,
You cannot use BlazeDS or LiveCycle DS for .NET back end.
Those products are for Java back end. You should be using Flex and
Weborb, if you want invoke .NET objects from Flex application using

Convert Webdynpro Java WebService

Hello,
I have a Webdynpro Java Application deployed on the Portal Server. I want to convert this Application to a WebService and call it from a BSP Application . How can I achieve the same ?
Any help would be highly appreciated.

Hi,
As John rightly pointed out, you cant convert a webdynpro java app to webservice. as wd java is meant for UI developing. But you can convert a RFC to webservice and can use it in your application.
Kindly refer this link for more information:

How to create a calender view in webdynpro java EP 7.0

Hi ,
I want to create a calender view in webdynpro,
Requirments are
1. it should be current month view
2. Below each day i want to show office in-time and out-time in two cloumns(these values will be coming tru RFCs).
ie

10am | 4pm
Is this possible in webdynpro java EP 7.0 ?
Please help me
Thanks

Hi Kumar,
If you are using EP7.0, there is no calendar UI element in webdynpro development. There is only date navigator UI element. This is demonstrated in the below article.

Passing Parameters via Post Method from Webdynpro Java to a web application

Hello Experts,
I want to pass few parameters from a web dynpro application to an external web application.
In order to achieve this, I am referring to the below thread:
HTTP Post
As mentioned in the thread, I am trying to create an additional Suspend Plug parameter (besides 'Url' of type String) with name 'postParams' and of type Map.
But when I build my DC, I am getting the same error which most of the people in the thread have mentioned:
Controller XXXCompInterfaceView [Suspend]: Outbound plug (of type 'Suspend') 'Suspend' may have at most two parameters: 'Url' of type 'string' and 'postParams' of type 'Map'.
I am using SAP NetWeaver Developer Studio Version: 7.01.00
Kindly suggest if this is the NWDS version issue or is it something else that I am missing out.
Also, if it is the NWDS version issue please let me know the NWDS version that I can use to avoid this error.
Any other suggestion/alternative approach to pass the parameters via POST method from webdynpro java to an external web application apart from the one which is mentioned in the above thread is most welcome.
Thanks & Regards,
Anurag

Hi,
This is purely a java approach, even you can try this for your requirement.
There are two types of http calls synchronous call or Asynchronous call. So you have to choose the way to pass parameters in post method based on the http call.
if it is synchronous means, collect all the values from users/parameters using UI element eg: form and pass all the values via form to the next page is nothing but your web application url.
If it is Asynchronous means, write a http client in java and integrate the same with your custom code and you can find an option for sending parameters in post method.
here you go and find the way to implement Asynchronous scenario,

Pros & Cons of Using SAP PI Interfaces for Report Generation

Hi Guru's
I have a Scenario's like
I have to generate a customized report in SAP with the main data's available in SAP ECC and some required data available in the Legacy System.
I want to know the Pros & cons of using SAP PI RFC/Proxy adapter interface to get the data from the legacy system for each time the user execute the report in SAP ECC.
Thanks in Advance

There are couple of "dimensions" to consider in your PI interface design. For exemple when you are running the sizing exercise (Since we are considering adding a net new interface), you will need to capture specific information about new interface.i.e. S/A, adapters, frequency, avg payload size. etc..Note that the last two attributes will be hard to size properly in this case since you can't predict how frequent the end user will run the report which will impact the latency time required to pull the data. Latency will affect the user experience as visible side affect and definitely the SLA for other interfaces running at the same time.
On the other hand, the data you are trying to retrieve from the legacy won't be used for transactional purpose but for the end user to pull KPIs from the system which can affect ECC as well. You may end up doing lot hot fixes for your report (Assuming that the report is a medium complexity code)
There are other factors to consider but let's consider these are the major one.
Cheers,

Print button on my webdynpro JAVA page

Hi Experts,
Is there any way that I can include a print button on my webdynpro JAVA page. ON click of the Print button I have to print the entire Page. User is able to print the page by using the print option of Browser, but in that case if the page is having a vertical or horizontal scroll, print output will contain only the visible part.
Thanks and Regards,
Sarath Satheesan

Hi Sarath,
