GUI development in NWDS

Hi,
Is there any visual editor for developing GUI in NWDS.
I need to place my controls on the UI using the editor without having to specify the position in the code (something of a autogeneration of code for the components created in UI).
I am creating the UI using Swings.
regards
Raja Sekhar

Hi Jo,
I have installed Visual editor on the top of eclipse 3.1.
When I try to create a GUI in the eclipse, I am not able to place the controls on the UI properly. I am also not able to customize layout window to include controls in multiple colums adjacent to each other. When I click the Show customize layout window icon, "No layout options to customize the current selection" message appears.
I have installed Visual editor 1.1, then installed GEF 3.1 and EMF 2.1.2.
How do I set the Grid Layout manager. Is there any other software that I need to install.
Regards
Raja Sekhar

Dear All,
I am trying to install the EHP 1 for SAP NetWeaver Developer Studio (NWDS) 7.1 .It got installed once but when i was trying to deploy the application i was getting an error sayind that we need to have JDK1.5 Update 14 or higher for the installation.
Now i have JDK 1.5.0_14 installed in my system.So i Uninstalled the EHP 1 for SAP NetWeaver Developer Studio (NWDS) and i am trying to reinstall it but i am getting the following error

Nishita Salver

Dear Nishita,
I hope you have removed the older version of jdk before installing the new version of jdk. Also after un installation of NWDS, did you delete all the temp files and also the directories created during the original installation of NWDS. Also did you restart your system after the uninstallation of NWDS EHP1 and older jdk before reinstallation of the two softwares?
Regards,
Veera
P.S. The first thing you can try is restarting the PC and try resuming the installation, if it doesnt succeed, please remove all traces of NWDS and JDK, restart pc and then resinstall both of them.

Code developed in NWDS 7.1 CE7.1 not working in NWDS 7.1 EHP1

Hi,
The code developed using NWDS CE7.1 is working fine at runtime and then migrated to NWDS 7.1 EHP1 for a new requirement.The same code in NWDS 7.1 EHP1 is not working at runtime . The problem is with one of the columns in a table.This column is binded to a value attribute in NWDS CE7.1 whereas in NWDS 7.1 EHP1, this "value attribute" is now just an"attribute".
The column is no longer displaying the right value at runtime when deploying the code from NWDS 7.1 EHP1.
Please help.
Regards,
Reinuka.

Hi Satish,
Thanks for the reply.
Yes, the attribute's dataype is not effective at runtime.I had created a custom date datatype for this attribute and assigned a format"dd-MMM-yy HH.mm.ss" which is coming fine when the track has 7.10 sap dependencies but not when using a new track having same SCA file with 7.11 sap dependencies.I found it's not a problem with NWDS but when we with the version of the SAP dependencies added to the NWDI track.Kindly suggest.
Regards,
Reinuka Paul.

NetBeans or Eclipse: Which is better for GUI development ?

I am relatively new with JAVA, came from embedded software domain mostly in C.
My interest is to learn and develop the GUI applications using Swing.
I am currently in a process of evaluating the IDEs, Eclipse and NetBeans on Linux desktop environment (SuSE 10.3).
My primary findings found that, NetBeans is better equipped with GUI development while Eclipse needs to have a plugin installed.
For GUI development, I found that few of my fellow Java developer friends have mixed feelings about these two wonderful IDEs, in summary here are the comments:
1) Developing GUI is better without any assistance from built in designers of IDEs (e.g. NetBeans or Visual Swing of Eclipse). Because, they put extra 'garbage" codes which are very much IDE specific.
2) GUI development in NetBeans is faster and more productive than Eclipse
3) Visual Swing for Eclipse is not a matured product and it is far inferior than NetBeans' capabaility
Now I ask a question, what is the best practice to adopt for starting the GUI development ? NetBeans or Eclispse or IDE-less development ?
Thanks.

NetBeansThis is my preference for IDE's. Please note that as I stated that is my preference. There isn't any best, some are clearly better than others for one reason or another, but once again, that boils down to personal preference.
EclispseNot my preference.
IDE-less development ?IMO: that is just silly. Unless you just enjoy tons of typing; why would you ever embark on doing something without a tool to speed up the process. Now that is not to say that in using your IDE you should start out by just dragging and dropping up a storm and merrily running down the road in ignorance until you hit a rough spot and have things dramatically pointed out that you've really not a clue about what is happening. Use the IDE, but learn how to do the manual processes along with it. That means that sometimes you'll not drag and drop to build your GUI, you'll actually code the entire thing. And you really should learn to do things command-line like compile. Do yourself a really big favor too, learn the debugger. The integrated debuggers is, perhaps, one of the best inventions in productivity tools that has as of yet been invented for developers.
In any case, have fun... choose what you like, it really does come down to personal preference. I've worked in several shops over the years and most have come to the conclusion that if you can get the work done, and have projects that others can use, then to each their own preferences. The discussion rages on for and against each of the systems that you have mention--each have valid arguments--it boils down to what do you want and like.

GUI Development Paradigm

Hi everybody!
I'm quite new in ALBPM and I have some questions about it, especially about user interfaces.
I've been developing JSP aplications (using MVC frameworks) for a long time, and I can't figure out how does it fit in the ALBPM world.
What's the paradigm for GUI development? At first, I believe the screenflow should act like the controler, the BPM object is the model, and the custom JSPs are the views.
But... sincerely for me, the Screenflow/BPM object/Custom JSPs seem less flexible than a regular MVC (Struts, JSF, ...)
My question is: Is it mandatory to use screenflows, or I'm able to use a MVC architecture inside ALBPM? If it's possible how should I implement it?
For example: I have a custom JSP with some menu items, and this items are links to other JSP pages. This behaviour should
be modeled using screenflows or can I use another approach? What's the best practice for this task?
In MVC architecture, the menu will be inside an html form with an action pointing to a servlet (a controller). And what about screenflows?
Well, I'd like to hear some opinions about this, especially because i'm triyng to get used to BPM paradigm, and in my opinion the best approach for this is hearing from people who had experienced this situation.
Thanks in advance,
Thiago

Hi Thiago,
I think I see what you're asking. Let me know if I'm missing your point.
I personally try to have a Model version of the BPM Object. I'll build this object first. This object just has the attributes, groups and methods I need. This object will be used to pass information from the process into the individual screenflows and procedures and subprocesses.
I'll then create a View version of the same BPM Object. I create this View BPM object is created by creating an heir from the original Model BPM Object (right mouse click the Model BPM Object and click "Create Heir"). When I know I'll need to collect several Model BPM Objects into one View object, I'll instead add these as attributes (each attribute would be of the type of the desired Model BPM Object). Built this way, this View Object would have all the attributes and methods of the Model object. You'd also add to this View Object the presentations you'll later use inside the screenflows and any methods you'll use inside these presentations.
At this point, you'll have a clean Model BPM Object - uncluttererd by presentations and presentation methods. You'll have View BPM Objects that will be used exclusively inside Global, Interactive, Global Creation and Interactive activity screenflows.
When I create a screenflow I always do it after I first have created a process with a BPM Object as an instance variable already defined in it. This object does not have to be perfectly defined. It just should be present in the process. If I decide later that I need additional attributes and methods, these can be added at any point in the development lifecycle. This object is the Model object I'll pass to my screenflows.
Second, after creating this process with the BPM Object (usually the process at this stage just shows the "Happy Path") I'll add the necessary Interactive activities used in the process. (finally getting to your question) I then create screenflows for each of the Interactive activities (right click the activity -> Main task -> pick screenflow from the dropdown -> New). As you're doing this from this panel, be sure to map the Model object as both an incoming and outgoing variable into and out of the screenflow. Some people also map the "result" predefined variable as an outgoing variable from the screenflow. If you do it this way, you'll not have to do any of the 4 argument mappings you'd have to do had you added the incoming and outgoing variables manually. If you decide to do this manually, many times you'll find yourself spending an hour tracing down where you lost the contents / changes made inside screenflows.
This best practice makes it easy to pass in and get back the Model object to and from the screenflow. Once inside the screenflow, you'd do the Model to View to Model object mapping described in my earlier post.

Dan

The reason for this is due to our JVM. This application is being developed for an embedded system. There are no swing components in this JVM environment for a couple reasons: size constraints and possible license issues.

Introducing JavaStates - a new API for state based GUI development in Swing

JavaStates partially implements the semantics of D Harel' statecharts.
It is currently hosted as source forge project:
[https://sourceforge.net/projects/javastates/]
, and has been used for several years for teaching Java Swing and the specification of man machine interfaces at ESIL
[http://www.esil.univmed.fr]
[http://laurent.henocque.com]
The project provides several demos, including a full fledged swing text editor, and is stable.
Details can be found here too:
[http://javastates.posterous.com/]
I'd be very happy to interact with both experts and users.
I claim that Javastates tremendously improve the quality and speed of GUI development.
Do you agree?
Edited by: lhenocque on Mar 4, 2010 4:18 AM

Thanks for the good practise hint, and many more thanks for your interest.
I haven't tried anything but don't you get an explosion of states?
explosion of states is controlled by concurrent regions. Two states in two concurrent regions can be active at the same time.
There can be no 'explosion' anyway since the states are programmer declared. The list is finite, and under control.
For example the program I'm working on has a table and actions are enabled based on:
-no selection/single selection/multi selection
-top/bottom row selected (move up/down action)
-user read/write permission
-properties of the object of the selected row
The situation you describe is handled by (at least) four concurrent regions.
The typical error is usually forgetting a particular one which result in action being enabled/disabled when the shouldn't. Currently solving that by having a callback method which enables all the action correctly and gets called whenever there is a selection/security/etc update.
Javastates cares for both setting the properties of the states (including the callbacks to fire) and for the cleanup. Using this allows for defect free interfaces in the sense that nothing can be left over.
Using Javastates helps you to separate your logic in the same way as object programming with virtual functions does. You should end up replacing a code with many if/thens by separate listeners, dynamically set by callbacks.
Also fluent interface method chaining is nice until it becomes a flood in my opinion - similar to how GroupLayout is better handled by Matisse GUI builder than by hand, JavaStates might benefit more from a graphical tool.
You are right. Both apis exist. The fluent api is provided for simplicity, since it prevents from declaring useless local variables.
Also for a GUI builder. I created the foundation of Javastates for an interpreted language called WIZ in the IDE Openside around 1990 (that was in C).
Then later I implemented a subset of the current Java features in C++, that were interfaced in the GUI Builder called ILOG Views.
So yes I agree a GUI can help, but anyway the Java code resulting from using states is mare more concise and structured than it would otherwise.

What was the first GUI development tool of Oracle?

Hi,
I am an Oracle Developer and currently developing my own Website dedicated to Oracle, especially on the development tools. In my website I have a page dedicated to the history and development of the Oracle Developer tools, from SQL*FORMS 1,2,3,4 etc. to the Current Developer. What I want to know are the release dates of the first Windows based development tools by Oracle. I know that Forms 4 was the first Windows based GUI development tool Oracle released ( I think it was called Oracle CDE). But I don't know when it was released. Was it in 1993 or 1994? If you can tell me which month it would be even better and more accurate. I got to know through the Internet that Developer/2000 Version 1 was released in March/1995. Is this true? Any information on this would be greatly appreciated.
Thanks & regards

Hi,
the first version of CE was 7.1. Followed by 7.11 and 7.20. But you have to be carefull. There was a netweaver release 7.0 which already included parts of the components shipped with CE (e.g CAF and WebDynpro). But these are different releases, so it is not possible to do an easy upgrade from NW 7.0 to CE 7.1
Best regards,Stefan

IDE for gui development

Does any one know a good ide for java gui development other than JBuilder...
thanks
SP

I use both JBuilder and Eclipse, but to be honest, I never created a GUI with any of them. In my experience, at least some GUI-creators produce a lot of junk - the GUIs always looked different during runtime than they did in the editor window. Do it like I do and manually code them.

GUI development direction

I am trying to get a feel for where Sun is heading with GUI development tools. The visu tool (XDesigner) included with Forte C++ installs with "support" for integrating a numer of widget sets into the base program. However, I have never been able to create a fully functional widget set-specific version of the visu tool with the supplied integration files. The CDE widgets can be integrated somewhat successfully, but other user_widgets directories like that for Motif 2.0 are missing files, and it's clear that these were never tested before pressing the CDs. Without these additional widgets (combo boxes, tabbed panes,...), it's not possible to create a reasonably modern GUI. These problems are not addressed with each new release or update, which indicates that it must not be a priority for Sun or other developers. I've asked about this on various tech support calls to Sun, but no one had information. Does anyone have any clues to Sun's direction regarding modern GUI development with C++?

Motif 2.x development is not supported in Forte Developer 6U2 and previous versions.
It will be supported in Forte Developer 7 though.
You can try out the FD7EA2 package with your code for now, but FD7EA2 does not honor the "visu" name and "VISUROOT" environment variable. You will have to change "visu" to "xdesigner" in any existing makefiles and "VISUROOT" to "XDROOT". Other than that it should be compatible.
FD7EA2 is available at http://wwws.sun.com/software/Developer-products/info/features/fd7ea2.html .

Tools for GUI development in Java

hi,
Can anybody tell me which r the tools available for GUI development using java?which could be the best

Take care not to produce much source code! Use a suitable framework rather than a tool and save maintainability. E.g. http://www.must.de/cameleon.html

Some issues regarding JEE adapter module development in NWDS 7.1

Hi guys,
I'm trying to develop my first AM in NWDS 7.1 and I'm facing some issues which I'd be happy if you would help me out with.
1, I'm going step by step according this document http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/c0b39e65-981e-2b10-1c9c-fc3f8e6747fa&overridelayout=true but I have an information Warning "Classpath entry PI_AF_LIBS/... (all PI AF 7.1 classes) will not be exported or published. Runtime ClassNotFOundExcpetion may result". Why am I getting this if I have checked the checkboxes with these libraries in Project->Preferences->Java Build Path->Order and Export(tab)? If this checked I'd say it will be exported with the project.
2, I need to create an SDA file to deploy the module, because the server is not available directly. So first if I'm not wrong I need to have an EAR file which I can use to create the SDA. But how can I get this EAR file? This document describes only direct way of deployment.
Thanks in advance,
Olian

1. The jars need to be referenced in the project build path to enable the compilation of the code
The warning can be overlooked as the jars are present in PI.
2. The EAR Project that gets created (as per the description in the referred document) can be exported to the get the necessary
ear file.
