Design considerations for custom C223

Hi all,
I'm building a custom report using C223 as a base. I think I've determined that the struct mkal-expand is used to store the record set returned upon executing the transaction. I want to add a couple of fields to the struct by including another struct, which I define, in the mkal-expand struct. Is that a good aprroach for adding my fields to the report? Also, when I view the screen layout in design mode all of the fields which are displayed in the executed report are NOT displayed? Why...and would I add my fields in that case?
regards,
Mat

Hi WalterLaan
Thanks again for your assistance. I still think I might be better off drawing my own charts because I know that I have a bunch of unique stuff that I have to add to the charts (results of custom market analysis techniques)... e.g. if I have to draw custom annotations above (and/or between) the 5th and 10th bars on the chart, it will be easier for me to do this if I have drawn the bars myself (i.e. I'll know exactly where the bars are on the screen... to the pixel)... whereas there may be guesswork involved if I have to find the location on the screen of the 5th bar drawn by a third-partly library (unless they explicitly provide that in their API, to determine the x and y co-ordinates of a particular bar).... but even if they provide this, I may have to deal with the complexity of having to add a transparent pane above the chart element (or some other complexity) just so that I can go ahead and draw my own custom annotations to the chart.
Again, for now I'm thinking I should just draw the charts myself... that doesn't sound too hard. The most important thing I needed to get my head around was the interactions between the data processing piece and the GUI components. I think you have laid out a pretty reasonable system for me in that regard... so thank you.
Just a quick question.... Does repaint() have to be called from the Event Dispatch Thread? I'm thinking not because as far as I understand it just schedules a paint event. I think what you said made sense... just call repaint after each new piece of data is processed.
Thanks for all your help

Design considerations for mobile version of website

My company has just implemented a new version of our coporate website using Oracle Portal, and ADF. However we do not have comprehensive mobile support but it is required. From my research I've learned we should be using ADF mobile. However, the resources I have found have been geared more at developers and I work as a Business Analyst. Can you point me to online resources (white papers, tutorials etc.) that deal with requirements and design considerations for porting over to a mobile version?
Thanks in advance.

My apologies for lateness in checking this thread.
Here is an article I wrote that might help. Most of the paper is geared toward developer, but the first few sections talks about best practices for mobile browser app in general, not just for iPhone. http://www.oracle.com/technology/pub/articles/huang-iphone.html
You can also check out this link: http://www.orato cle.com/technology/tech/wireless/adf_mobile.html.
As for design consideration, a few rules of thumb:
- First, obviously use ADF Mobile and Trinidad components. We put a lot of effort in adding rendering support for different mobile devices.
- Next, figure out what devices you want to support. Browsers found in smartphones varies greatly, and in consumer/feature phones, the support is even less consistent. In general you should be able create one app/set of screens for all mobile devices, but you should plan on having ability to test it out on different devices.
- Determine what information is really needed by mobile user. Not all information available in desktop application may be applicable for mobile users
- Design your mobile screens based on a few key principals:
- Display data as user needs it, instead of trying to display everything. For example, instead of displaying master-detail data on the same screen, break it out into 2 screens. Master data may be a list, and user would click on a particular piece of data to look at the details of that master record.
- Provide navigation buttons on each screen, and ensure they are easy to get to on a page. For example, using the iPhone paradigm, there is a navigation bar at the top of the page where you can go between views.
- Place command buttons at location where it's easy for user to get to. For example, if you need to allow user to modify a long list of fields, you may want to place save button on top and button of the screen, so user can easily get to it without having to scroll around too much.
- Use style sheets to achieve mobile-platform optimized UI. For example, if you intend to support touch screen devices (iPHone, BB Storm, etc), then style your application so buttons, command links, etc, are big enough so it's easy to get to. For non-touch screen devices, then it's OK to compress the UI, but ensure user can easily flow between controls to get to the functionality they need. For example, using a trackball to scroll to a button.
Thanks,
Joe Huang

Design advice for custom painting

Hi,
Can someone give me some high-level design advice on designing a JPanel subclass for custom painting? My panel class is becoming very complex, with lots of drawing and scaling methods, so I'm wondering if I could abstract away some of these graphical elements by creating new classes to make the design more object-oriented. However, I'm finding that there are also disadvantages in representing some of my graphic components as classes. Specifically,
1. It will lead to a much higher level of class coupling. My panel will depend on all these new classes to work correctly. In fact the situation is even worse because my panel is an inner class and, to do some of the scaling, needs to use methods from an object stored in the parent class. I would therefore have to also pass this object reference as an argument to many of these new classes.
2. It will lead to a lot of awkward passing of data between classes. For example, I need to use g2.drawImage(img, x, y, w, h, this), so I will have to pass not only the graphics context but also the panel reference itself.
Is it common for panel subclasses that do custom painting to be complex?
thanks,
Eric

I wrote the map view for a commercial GIS system. Drawing and scaling on a JPanel is challenging, but it need not be complex.
1. To eliminate class coupling, you need to create a couple of interfaces: Renderable (what you want drawn) and Renderer (the thing doing the low-level drawing). Renderer will have before and after setup and reset methods (to do things like scaling and rotation), and methods that the renderables can use to draw graphics. The Renderable interface can be as simple as a single method: draw(Renderer).
Every type of graphic that you draw on the screen would be a different class that implements Renderable, and which knows how to draw itself using whatever lower-level drawing commands you put in the Renderer. If you construct each Renderable in terms of java.awt.Shape, then Renderable.draw() could call a method Renderer.draw(java.awt.Shape, java.awt.Color).
2. The Panel becomes fairly simple. It has a Renderer and a collection of Renderable objects. Its paint() method calls the Renderer setup method, calls Renderable.draw(Renderer) on each object, and calls the Renderer reset method. Each Renderable in turn calls Renderable.draw(java.awt.Shape, java.awt.Color) one or more times.
Renderer should get a Graphics2D from the Panel when the setup method is called. That's when the Renderer does all of the scaling, positioning, and rotation on the Graphics2D. The Renderable implementations shouldn't even need to know about it.
I don't think custom painting code is necessarily complex, merely challenging to write. If you're only drawing a few lines and circles, you probably don't have to be too concerned about design elegance and code maintainability. The map view I designed for our GIS system, on the other hand, has to handle all kinds of map geometry, icons, text, and aerial photos.

Design approach for custom Fiori application

Dear Experts,
Good day to all...!
I am having a query on finalizing design approach for one of my custom Fiori Application development using SAP UI5.
Current Application design and Features:
As now we are having application, which is been used in laptops. The application structure is like (SAP R3 --> SUP -->UI (using .net) [back-end à Middlewareà UI).
The UI is hosted on IIS server and the application type is desktop, so the users can use the application in offline as well.
Once its connected to internet, they push all the data back to SAP via SUP.
Proposal :
We are planning to migrate the same application into Fiori with same offline features and extending to mobiles and devices.
I have few queries here.
What will be the best approach to deploy the application either SUP(Latest version of SMP) or SAP R3.
If SAP R3 to deploy App:
If we choose to deploy the application in R3, How to support the offline usage mobile and devices.
Will the HTML5 local storage or indexed DB’s are sufficient to support the offline usage.
In this case, Shall we drop the SUP/SMP, Since the application directly accessed from SAP R3 ..?
SUP/SMP to deploy the app:
In this case, I need to create (wrap the ui5 files into hybrid application) a hybrid application to support the mobile and devises as native application..? Correct me If I am wrong..:)
Hope I can use the SUP/SMP local storage options to support my offline usage..? Correct me If I am wrong..:)
What will be the best option to support desktop offline usage.
We are yet to take a decision on this.. Please provide your valuable inputs , which will help us to take some decisions.
Thanks & Regards
Rabin D

Hi Anusha,
considering the reusability aspect the components approach is the much better one (see also the best practices dev guide chapter regarding components SAPUI5 SDK - Demo Kit).
It allows you to reuse that component in different applications or other UI components.
I also think that the Application.js approch will not work with Fiori, cause the Fiori Launchpad loads the Components.js of the Fiori app in an Component Container.
Best Regards, Florian

JSF Design support for custom controls

I am creating some custom JSF components, for use in my projects. They work fine, but I was not able to make them display correctly in design time (I am using Websphere).They appear like small rectangles, even when they are grids. What is the standard way to provide design time support to my controls? Or al least a way to show them properly in Websphere designer? There must be some way to make it work, because standard components and IBM components are displayed correctly.
Some hint?

At the moment, the best you can do is fill out all the metadata in faces-config.xml for your component and renderer. Beyond that, each tool developer is currently defining proprietary XML metadata and/or programmatic extensions to provide better tool support. This is, of course, an awful state of affairs, and there are the beginning of efforts today to work towards common metadata and extensions for component developers.

Design Suggestion for Custom ADF Application

Hi
I have a custom database table.
I have a custom database view which has query from multiple tables including the above table.
The custom table in the view is joined with other tables by columns like inventory_item_id, organization_id etc.
I have to show user a screen where the results of this view are shown in a table.
The user should be able to enter some data in the screen for these rows.
(he will be able to enter the data only for fields from my custom table)
When he press save button, we should enter the new data given by user into the custom table
along with some other values from view rows .. like inventory_item_id, organization_id etc ..
Can you suggest a best approach to achieve this ?
I have to use BC4J for Model and ADF For UI.
As far as my knowledge goes, I think we will not be able to do this with an updateable view since we might hit the error
ORA-01779: cannot modify a column which maps to a non key-preserved table
Is there a design pattern we can follow in BC4J so that this can be achieved?
Thanks for any help.
Sameer

Any view can be made updatable if you write INSTEAD OF triggers for it. That might be a good solution for you. You can also base a View Object on more than one Entity Object, and as long as there are good associations between the EOs it ought to work fine.

Design considerations for wrapping higher level process

So Ive used workflow now on a few projects and have become comfortable building/coding with it. Recently a discussion was started to design a new process to automate a part of the business Im in and there are several different departments, each with
their own different functions and processes that they perform. During this discussion, the thought came to me - why stop with just the "small" picture where I was using WF to contain and execute business rules, but also wrap the higher level
abstractions also.
For example, a department performs steps A, B and C. Each step might have some branching in it (if/then etc). Its only the "steps Im using workflow currently.
Above the department, there is another layer, lets call it "group". There would be several different groups, each with its own departments, some with the same name as other groups, but the internal structure might be different for a given
department between groups. So this means that if I modeled a department in one group, I cant assume I can reuse that department in another groups workflow.
My main unknown however, is how would a user interact with a workflow that was this high level. Abstracting higher levels, means users dont need to interact with or execute the whole workflow each time, only a part of it. So am I looking at pausing/resuming
the bigger workflow? How can I "skip" to a certain stage or area of a workflow, bypassing the stuff that has already been done?
Correct me if Im wrong, but this seems to be where I need to look at bookmarks?
In my case, something similar to an order in a shopping cart is what would be the input type for the bigger workflow. There are several different groups of users that have to set or add properties to associated objects (sql tables) related to the order
before it can be marked "complete".
How would you tie together a "wizard" type concept with workflow? This seems to be the type of model we are considering. A user takes an order a few steps, then another user from a different group/department adds some attributes and
the workflow/wizard continues a few more levels down. Finally, after all the rules have been matched and required data provided, the workflow can "finish".
Hope my description seems clear.

If you want to skip to certain state or bypass what stuff that has been done, you need give logic judgment first. Bookmarks are the mechanism that enables an activity to passively wait for input without holding onto a workflow thread. When an activity signals
that it is waiting for stimulus, it can create a bookmark. So bookmark is available for you during create this application.
Here are some workflow applications, see:

Design Considerations for a Repository Manager in a clustered environment

Hi,
I am currently building a repository manager for a backend document management system. Our portal is installed in a load balanced clusterd environment and we are creating the following functionality in the repostiory manager -
- Browse content
- Read/Write document Metadata
- Upload/download documentation
- Reserve/Unreserve documentation
- Search
How will a clustered environment affect the implementation of the repository manager? Would I need to check for a clustered installation in any kind of way in my code? Currently I do not see why this would be necessary, but i'm not entirely sure and I need this manager to work in a clustered environment.
I could see this as being an issue if we are caching information about the documents in the repository. However, we are not. We will only be caching user information which can be stored separately in a single cache on each server.
Thanks for your help,
Scott

Hi Scott!
There might be two reasons for knowing whether other cluster nodes are running or not and for communicating with them:
- synchronizing access to the backend
- synchronizing caches
If your repository manager must care for serialized access to the backend you will have to synchronize cluster-wide. You don't have to, if your backend can handle parallel access on its own (like a web-server).
If you cache data in your repository and you want to update the caches of the repositories on the other cluster nodes (maybe because you don't get events for changed data from your backend), you must think of sending messages between cluster nodes. You don't have to, if you think that the expiration of your cache entries is shorter than the required timeliness of the data.
Kind Regards, Dirk

Design view for jsp custom tags.

when we drag-and-drop custom tag control in the source of jsp page, when we switch to the design view of jsp we should be able to view controls as desired.
Observation: 1) Eclipse 3.2 doesn't have design view for jsp pages.
2) which software uses the design view. we need to extend eclipse core framework and we do not find any technical approach document to proceed further on this.
3) RAD 6.0 we can see a JSP in design view.
I'm searching for any technical approach document to create plugin that can intercept the custom tags and provide a design view.
Will any one suggest the plugin for that.

Can I write Design-time for JSP custom tag(not JSF components)

I have some old JSP custom tags(not JSF components), and I want to use them in the IDE through the toolbox.
Now I have already written the BeanInfos for these tags, and they can be drag from the toolbox; but it will throw a Exception when render the tags, and the properties in the Property Editor are not which I describe in the BeanInfos.

Entering custom backend service in Design Time for Processes and Forms

Hi all,
I am trying to create a form that have 3 fields:
1. pernr
2. ename
3. effective_date
I done all the necessary setup of BADI ,class, interface and form.
However I cannot seem to insert my custom backend service in the Design Time for Processes and Forms workbench (t-code:hrasr_dt).
Currently, I am just using SAP_PA for my backend service which is unable to load the ename into my form. The code in my custom class will not be triggered if I did not use my custom back end service in the Design Time for Processes and Forms.
Whenever I tried using my custom back end service, I will encounter the assertion_failed dump.
Anyone have any idea?
Edited by: Siong Chao on Dec 22, 2010 6:35 AM

Hi Siong Chao,
The filter name you have used in the BADI for your generic service requires to be defined in the Create / Edit Generic Service - Definition.( You can see this on selecting the Back-end services node under Form Scenario definition while using HRASR_DT transaction code)
Once you do that, you can import the fields defined in the Generic service BADI - using the same procedure used in standard SAP backend sevices.
Hope this clarifies. Please let me know if you have any further questions.

Architecture/design templates for SOA-BPM?

Dear All,
Can anybody point me towards architecture and design templates for SOA-BPM?
It can be platform-agnostic, say from general BPM standpoint; and/or customized to cover product-specific considerations e.g. SOA Suite 11g or OBPM 11g. A logically structured one covering both would be too ideal.
