Regarding webdyn pro java

Hi to all,
hwo many model objects we can able to create in single component controller?is there any limit?
Hwo many custom ctrollers we can create in one component?is there any limit?
if we map model and view controller directly is there any problem compared to normal connection like connect model and view controller through component controller?
Regards,
surya.

Hello Nari,
You can map model to view directly and this is okay.
Usually the best practice is to take advantage of MVC architecture WebDynpro is built on. It will be fine to map view controller with model directly as long as the view only displays data with out manipulation.
You want to format data before display, you can do it both in your component controller and view controller, and application runs fine, but say you need to display formatted data in more than one view, you will have to implement the same in other views to. This is not re-usable any more. It is only practice to keep such kind of logic or code in component controller or custom controller at your convenience so that it becomes re-usable saving you from reimplementing the same again and again.
About your other questions about number of models and custom controllers, there is no limit if I am not wrong. But it is not a good practice to overload your component. There is concept called componentization in Webdynpro, which can be used to architect huge development. Link below can help you in understanding componentization.

Colorful Screens in Webdyn pro

Hi All,
I am developing a PDA application using Netweaver Mobile 7.1. I am using NWDS 7.1 and developing the applications in the Handhelds and Laptop perspective.
How can i make the Webdyn pro screens more colorful and presentable ? I mean is there any option to add a section header and to change its color , background color, color of radio buttons or any other feature ?
Regards,
Madhu.

Hello,
There is a configuration file where you can change the color of the different part of the UI. I do not have NW 7.1 installed so I cannot tell you exactly where that file is, but there is a way to edit it.
Thank you,

Standard Adobe Forms in webdyn pro??

Hello,
I'm having a problem, I was asked that utilized the following standard webdyn pro's to change the LOGO of the company. Any idea which forms adobe used in these cases?
Webdyn pro's standard requested:
WDC_WSAM_SHMAE_SEARCH_MAT
WDC_WSGM_MAT_DOC_PRINT
WDC_WSPO_PO_DOC_PRINT
Another question is where are these configured webdyn pro in spro, any ideas?
Please Help me.
Thank you

Hi,
If i remember correctly then I think you should be able to see the adobe form only when you click on the overview/print preview button check under that action but ai not sure that you would be able to change then entire form itself. May be you should ask your fictional consultant that where does he configure this adobe form.
Since in e-rec we have different adobe forms for different purposes and i think some where these forms are configured against each process...
Are you looking to change at the WebDynpro component level or from adobe form level itself. You can access the form from SFP transaction.

Pavan

7.1: Mobile Webdyn Pro: set colors

This is a question regarding NW Mobile 7.1, PDA development.
I am using NWDS SP05 P01
How can I set the background color of a row in a table or in a rowrepeater?
Can I set anything else except using the "design" property, which does not give much control.
Can I display any lines to separate a standard navigation header?
Thanks, Andre

Hi Chintan,
thanks for pointing me there, but unfortunately I am developing for the mobile client. This is Webdyn Pro Lite, which means that many features are not available. The design features are limited compared to the Host Webdyn Pro ...
There is a setDisign method, but no explanation, what values are what.
public void setDesign(int textViewDesign) {
setPropertyValue(PROPERTY_TEXTVIEW_DESIGN, new Integer(textViewDesign));
But I really hope that colors can be set ...

Webdyn Pro - Grey out certain rows in ALV?

Hi guys,
I'm quite new to webdyn pro. So please bear with me
I've a webdyn pro component which displays a simple alv output on screen.
I have a requirement where I need to check if lets say Status = 1 or 2 or 3 or 4.
If its either one of those status, grey out those row.
How I'm displaying it is
node_searchinfo = wd_context->get_child_node( name = `SEARCH_DATA` ).
node_searchinfo->bind_table( it_searchdata ).

Hi,
You can add new attribute "CellDesign" of type WDUI_TABLE_CELL_DESIGN to your structure.
bind this attribute to alv columns cell design. Something like this
field-symbols <wa_colum> like line of lt_columns.
lt_columns = l_table->if_salv_wd_column_settings~get_columns( ).
loop at lt_columns[] assigning <wa_colum>.
<wa_colum>-r_column->set_cell_design_fieldname( value = 'CELLDESIGN' ).
endloop.
fill the celldesign value 00 (standard) and according to your status fill celldesign value (see domain WDUI_TABLE_CELL_DESIGN ).
This has been discussed many times in SCN , so you could easily find resources if you do a search.

How to generate Webdyn Pro URLs

Hello,
Within the class structure of our system hosting eRecruitment 6.03 there is a class and method with which I can generate a valid url for a posting object with the following code:
       CALL METHOD cl_bsp_runtime=>construct_bsp_url
          EXPORTING
            in_protocol    = 'https'
            in_application = 'hrrcf_pinstappl'
            in_page        = 'application.do'
            in_parameters = lt_params
          IMPORTING
            out_abs_url    = abs_url
            out_local_url = local_url.
Is there an equivalent method for generating a URL which will call the Webdyn Pro interface instead of the BSP.
Thanks,

Need Expert Advice regarding oracle and java objects

In our project, we are submitting data for many screens at a time. Some screens will have a list of records to be submitted. There is also some hierarchy among the data up to 4 levels.
In such a scenario, we need to know the best way to exchange data between Oracle and Java. Currently java holds the data as objects, where each object may contain an array of next level of objects in it.
Is it best approach to pass the entire data with hierarchy to Oracle using nested table approach and internally oracle handling the data? Is there any other way to do this?
Also in some scenarios we need to pass the entire information for all the screens in one shot with the hierarchy. So we need to know a solution for that also. Could you please help us in this regard?

Regarding usage of java script in adobe forms

Hello experts,
Please any body help me out with what events i should use in java script / formcalc .
send links for java scripting and formcalc.
Thanxs,
adi.

The reference for Formcalc is available inside you designer installation directory.
Like this one C:\Program Files\Adobe\Designer 7.1\Documentation\EN\FormCalc.pdf
There you can also find general LifeCycle Designer Documentation (Designer.chm)
In this file goto Creating Calculations and Scripts -> Events -> List of events
As for JavaScript - reference is not in the package, so you have to search a bit. Something is available:
Like this one: http://partners.adobe.com/public/developer/en/tips/CalcScripts.pdf
Hope this helps!

What's the general consensus regarding Generics in Java?

Just curious what folks think about how it's implemented in Java and whether you're in favor of it or not (not that it will make any difference).
I haven't been using it yet because I am still working on 1.4.x, but I've been familiarizing myself as best as I can with how to use them.
I realize they fill an important need, but I am not convinced they were/are worth the rather steep price paid for readability.
Curious to get others opinions on this. Regards,
~Bill

So "new MyWrapper(aString)" is untyped, we need to
use "new MyWrapper<String>(aString)" whichviolates
the principle of Dont-repeat-yourself.I don't think so... what if I wanted to create
something like this?
new MyWrapper<Number>(new Integer(4))That's still possible. My problem is that it works exactly as I'd like it to work as long as I call a method, but not when I instanciate a new object. Let's assume for a second that MyWrapper has a static generic method createWrapper() that just calls the constructor:
public class MyWrapper<T> {
     private T foo;
     public MyWrapper(T foo) {
          this.foo = foo;
     public T getFoo() {
          return foo;
     public static <WT,VT extends WT> MyWrapper<WT> createWrapper(VT foo) {
          return new MyWrapper<WT>(foo);
}Here WT is the generic type of the returned wrapper (WrapperType) and VT is the type of the value(ValueType).
Now we see a strange discrepancy on how the object instanciation ("call of a constructor", so to speak) works and how calling another Method works:
MyWrapper<Integer> i1 = new MyWrapper(Integer.valueOf(1)); //unsafe, not infered
MyWrapper<Integer> i2 = MyWrapper.createWrapper(Integer.valueOf(1)); //ok, everything fine
MyWrapper<Number> n1 = new MyWrapper(Integer.valueOf(1)); //unsafe, not infered
MyWrapper<Number> n2 = MyWrapper.createWrapper(Integer.valueOf(1)); //ok, everything fineIf you compile this code (or simply paste it in any modern IDE) you'll see that you'll get warning in the two lines calling the constructor. While the lines calling createWrapper() seem ok. So somehow the compiler can infer the type information when calling a method but can't do that when calling a constructor. That's what's troubling me.
