How to ... the whole thing?

[Former Member]

Hi everybody,

I am very new in creating web dynpro application and I want to know what I have to do. Sounds like a big problem and it is. I started with web dynpro a few month ago and I know how to bind a adaptive RFC model and how to create a custom controller but that's it. Now I want to ask if someone could help me learning a little bit more about web dynpro and what I have to do. Since I started working with it I looked into this forum to found some information and sometimes it really helped me. Once I found a threat where someone asked the same questions like I do at the moment but I do not know where it was and how I get there again. Maybe someone could link this threat if he knows what I mean. Or maybe someone would help me with some questions I have. My problem is that I don't know what I have to do, to create what I want. An as an additional problem, no one of my colleagues can help me, because no one knows web dynpro as I do.

So please send some links where I can learn to work with web dynpro.

If there is someone out there with to much time maybe he could help me with all my questions but one day I want to be able to help my selves.

I hope you do understand what I want, because my english is not the best (more worst than everything else)

Thanks a lot and bye

Andy

Hi again,

first I want to thank you all for the fast and good help and for all links that you guys send me. Now I think that my problem is not web dynpro but our back end system. I always thought that web dynpro is a program with more bugs than windows. But know I think that this program is working very good and that it allow me to do a lot of things. I think I understand now how I import models, bind them to custom controllers and create views. Hmm creating views seems to be very easy with point and click.

Now I have another question. What about the programming code? I use web dynpro for java and I want to know if I need some java experience or if this would be useful? Or can I do whatever I want by clicking the right buttons? For me, it looks like I don't need any experience in java but if it is useful I will look forward to find something where I could learn some basics.

Why I ask all these questions is because I'm a trainee at my office and no one knows more about web dynpro than I do. Well it is not that much, but hopefully it some day mean that I could work here after finish my training.

And I ask because my boss want me to find out if web dynpro could help the company in an economical way. Until last week my thought was "no" because I don't thought that someone could learn web dynpro on his own. But now I think that it is not that difficult. When I'm able to understand what web dynpro do, someone else will do it too.

Now here is a long message for a short meaning

So thank you again and byebye.

Hope to here from you as soon as yesterday

Hi Andy,

You don't need a lot of Java experience to code simple Web Dynpro applications, not really.

Of course, since you will be writing some code even in the simplest application it's obviously a good idea to know a little.

Of Java itself you don't need more than an understanding of the syntax and of object orientation in general. Remember, with Web Dynpro development you will be programming almost exclusively with SAP Web Dynpro classes so all the core Java experience in the world won't give you knowledge of these classes but it would give you the experience to quickly understand classes/objects, the programming model and it would mean that you already knew how to read/understand/use JavaDocs etc.

You will need to know how to write Java code but you certainly don't need any real previous Java programming experience.

Basic syntax knowledge of Java and a good programming head should see you through,

Patrick.

I recommend reading the book "Inside Web Dynpro for Java" by Chris Whealy. It explains in a very clear way those Web Dynpro concepts that are a little bit hard to understand at first sight like context mapping etc.

You do not need very deep Java knowledge to write Web Dynpro controller code. Honestly, the generated Web Dynpro classes are not suited for <b>learning </b>Java concepts because they are of a very technical nature.

Hi Andy,

https://www.sdn.sap.com/irj/sdn/developerareas/webdynpro?rid=/webcontent/uuid/8921447c-0501-0010-07b...; [original link is broken] [original link is broken] is a link to the Web Dynpro Sample Applications and Tutorials page.

<a href="https://www.sdn.sap.com/irj/sdn/developerareas/webdynpro">This</a> is a link to the Web Dynpro homepage here on SDN, a very good starting point for you.

I really think that you can find all that you need right here on SDN, the forum is great but remember that there's more to SDN than just the forum.

Also, if you haven't already done them there are many examples that you'll find in NWDS. Click Help -> SAP Wab AS Documentation -> SAP Web Dynpro Applications, there's a lot there.

Best regards,

Patrick.
