Rich client frameworks

Hello,
I am looking for a framework to develop rich client application quickly or easily. I have found the following frameworks:
1. TikeSwing: I have read it is a good choice, but it has not enough documentation.
2. SpringRCP: It can be another choice, but I think It is not matured.
3. With EclipseRCP or NetbeansRCp.
Anybody knows something about them? Any opinion?
Thanks in advance.

I also want to develop a rich client application and I decided to use NetBeans platform. The reason why I did this decision is that NetBeans IDE has a very nice templates which will guide you through the creation of your first RCP application. However, the documentation is not very good, but getting better each day...
Hope this opinion helps.

Swing Rich Client Framework

Are there any good swing rich client development and server integration framework?

jwenting wrote:
You're thinking too much about one thing, the client and user interface.
Don't. Think about the entire system.
What you're looking for is classic subscriber/publisher systems, where a client subscribes to updates from a publisher and the publisher pushes updates to published clients.
The client has to do nothing after subscribing to actually receive updates, but will of course have to actually handle the incoming data, for example by reading out a queue of incoming messages at regular intervals.Yes subscribe/publish is one type of communication which is the asynchronous messages I referred to, another is session-like communication when users chat (a user may have multiple chat session going and may also go out of band for some types of communication, that is not relayed via server) and then theres request-response communication when the client logs into the server (the client goes through 6-13 steps for authentication and data synchronization which is what I expect to use the statemachine for). You could say the client works autonomously while logging in, and is driven by user and server input the rest of the time. I should mention the protocol is well established and massive, Im not looking to design that.
So basically my design has an network IO thread that queues incoming messages to a protocol parser that turn xml messages into java objects. Then I have a BIG GRAY box that uses the java object to decide how to interact with the datamodel and other parts of the system.
The BIG GRAY box is the hole in my design (well I put some homemade design there but I dont like reinventing the wheel if there some principles or client design catalog somewhere that I just havent found using google). The example of updating the datamodel optimistically is just one example of the type of issues I have to deal with when the model is acted upon by both a user and a server.

JDeveloper 11g/ADF Faces Rich Client

Hello,
We are trying to decide between using JDeveloper 10.1.4 and JDeveloper 11g for developing a new application - we plan to use just the ADF Faces layer of the ADF Framework along with Spring and TopLink for other layers.
On one hand we think that is is safer to use 10.x version of ADF Faces as it may be more stable and on the other hand we are tempted to use 11g as it provides Ajax-enabled JSF Components.
Has anyone used ADF Faces Rich Client Framework for developing applications? Is it stable enought to be used for production-level applications?
I would love to hear your thoughts!

Hi,
don't use 10.1.3.4 to develop a new application now unless you have browser constraints with your user-base.
ADF Faces RC / 11g requires:
FireFox 2, 3
Internet Explorer 7.0
Safari 3.0
11g is a significant update and they have vastly improved/redesigned a lot of things that were difficult/complex to do in earlier versions.
Plus the 11g user interface is way better from a users perspective.

Rich Client advice

Hi all,
Been searching the archives.
I've developed a Swing standalone app and would like to convert it into a "Rick Client" but shifting certain parts over to a backend. My initial work has been a servlet on Tomcat webserver I maintain.
Can anyone point me to any up-to-date examples or Rich Client development?
Is the use of http requests/responses the standard way to do this or are there non-servlet examples?
There seem to be so many frameworks for this (Eclipse RC, Spring RC etc.)
Many thanks.

Thanks for the pointer. I will look at the tutorials.
I guess what I really want to know is what do people use as the most "vanilla"/non-framework communication between a Rich Client and a backend server.
Do the back ends tend to be servlets/JSPs or WebServices or what?
Thanks again.

[solved] problems w/rich client component demo

Hello -
I've been trying to run the rich client component demo as described in http://www.oracle.com/technology/products/adf/adffaces/11/doc/demo/adf_faces_rc_demo.html
in TP2 of JDeveloper 11. I've run into a few problems. (I am assuming that the article will work as written in TP2 since the date on the article is September 2007.)
(minor) The link to the demo under the "Running the Demo from Oracle JDeveloper" section is broken. The link in the section for "Installing the ADF Faces Component Demo on a Standalone OC4J" works.
Attempt #1: When I create the project from the WAR file and try to run index.jspx, JDev tries to compile the project. It shows the following errors:

Nevermind. I thought I had TP2 but I think it was really TP1. Creating (and running) the project from the WAR file works for me now.

Complete business server/client framework?

We would like to know which free and well-documented solutions we can use for:
- persistence framework
- business data object distribution from server to clients including change notification, server and client side caching and client side locking per user.
- (hacker) security for the above
- User/group based rights.
- Swing MVC framework
- Creating Swing data entry component with default functionality such as save, undo/redo and change checking.
Details below...
We have made an in-house client/server banqueting program from the ground up in (almost) pure Java. It is NOT web based, and we don't have any experience in using J2EE technologies (except for connecting to a mail server). What started out small became a quite large application that works nicely but is hard to maintain. It is time to do some major refactoring.
I dare to claim that almost all the problems we are facing (see below) can be found in any serious client/server business application.
Having said that, I find it quite difficult to find the right solutions for our project in the large place that is the internet. It would be a waste to spend days learning something only to find out it is not the way to go.
So I hope some of you can kindly suggest the right Java frameworks to solve our problems and reduce our ad hoc spaghetti code... Preferably, these frameworks should be used by many other developers and be well documented.
Current architecture:
Server:
Connects to a MSSQLServer database, creates POJO data objects (mapped mostly 1 on 1 with DB tables) and can provide these objects and simple reporting services (PDF, Word XML) to multiple clients over RMI.
The "writable" objects that clients request can be locked by a client before saving. When a client saves, or when the status of the lock changes, an event is pushed to all clients.
Client:
Connects to the server with username + password.
Uses Swing to show components like: a calendar with reservations, a reservation entry screen (including products), a customer entry screen, a product screen, etc...
Internally our system is much more complicated than it should be.
Some of the current major flaws:
1) adding a new table/object requires adaptation of at least 4 classes on the server and one HUGE data access class on the client and the creation of 4 different MSSQL stored procedures (selecting, saving = inserting, updating).
2) logging in over RMI is not done over an encrypted channel.
We have some concerns with the security over RMI (and our use of it).
* Is it possible for a hacked client to inject code into the server?
* It may be possible in our design that clients can spoof being another user.
* When a client saves an object, the server pushes this object to
all the other clients using remote method calls from server to the other clients. If I'm not mistaken we have to be very careful with RMI that one of these clients cannot block the code execution by not returning from this call...
3)We would like to have user groups that have rights for specific
objects such as allow nothing, allow read, allow write, etc...
4) our client side data access class does not automatically provide caching requiring us to create more or less ad hoc caches
5) Swing does NOT have a strict (enforced) model-view-controller architecture. Our client has severely mixed application logic with representation logic.
6) We have a few Swing components for data entry in data Objects we request from the server. They share functionality (and buttons) such as save, reload and popping up messages like "do you wish to save the changes?" none of these default functionalities have been abstracted, so it's often a matter of copy/paste and cluttered code.
When properly abstracted to a model undo/redo functionality might also automatically possible without extra programming...
To overcome point 1) we could use an Object to Relational mapping framework such as Hibernate or Cayenne.
To overcome point 2) and 3) we would like to be able to distribute the objects to the clients on the clients demand. The framework for this should include client side cache and the possibility for locking an object and receiving notifications from the server when another client changes the object.
(It would also be nice if all logged in clients can listen to a collection of objects (e.g. Products) and get notified when some client adds a new product without needing the lock on the Product collection.)
Preferably this framework should be hacker proof.
To overcome point 4) we would like to have an MVC framework for Swing with which we can bind fields in a data object or model to a view. When data is entered in the view the model is automatically updated and other views are updated, without the need of all those Swing specific listeners. Whenever the data is updated programmatically the views are also automatically updated.
For this I found JStaple as part of Cayenne, but I don't know if this is a mature and well-documented system.

After a day of checking out the Cayenne tool I have discovered that it works very well for creating a client/server "persistent" application (including web support through Servlets/JSP).
There is no such thing as "pessimistic locking" of objects and notifications of other clients though... This is a major drawback, so the quest for a great framework isn't over yet...
Edit: Spring Framework!!!
After a lot of time researching I am coming to the conclusion that (at least) using the Spring framework is the best bet.
The Spring Rich Client Project has a sample client application which can be run on top of their sample webserver application (PetClinic example).
http://spring-rich-c.sourceforge.net/
Spring can integrate with just about any Java libraries, frameworks and API's available, and has thought about almost all of the concerns I have.
The beauty is, that many concerns can be configured transparently using XML files and do not clutter your code (think about Acegi security, transaction management, etc...). This also enables you in easily switching many technologies. (e.g. if you use Hibernate/JPA switching a db is as easy as changing a few lines of settings.)
There are however a few things I am still missing:
* Undo/redo support in the client (preferably transparent to your code)
* Pessimistic locking at the application level. For this I might work together with people from the Terracotta "distributed virtual machine" (which also looks like a very good solution for scaling existing applications), or check the Spring forums if something like that has already been implemented.

Can I disable the ADF Rich client javascript?

I would like to work around the ADF framework and use my own javascript. Is there a way to turn off the rich client libs so they are not downloaded to the client? I want to use jQuery and my own javascript.
Thanks for any tips, tricks, links, or examples.

ADF is an MVC framework - ADF Faces is the View layer.
You can use the rest of the MV layers with a different front end.
So you can use ADF Business services and access them for example from a simple JSF that doesn't use the Oracle JSF components.
That being said, I think you are going about it the wrong way.
The real question is what specifically does JQuery gives you that ADF Faces doesn't?
What specifically are you trying to achieve and can't achieve with ADF Faces?

JDeveloper as Rich Client Platform?

Hello,
is it possible to remove all default extensions in Developer or SQL Developer and only use custom extensions?
This means, is it possible to do something similar to the Eclipse Rich Client Platform? Has someone already tried this ?
kind regards
peter

You would like to remove all the extensions that make JDev look like a developers's IDE. You would like to keep the plugin infrastructure that allows the development of modules of 'business functionality' (banking, science, media arts etc) as plug-in extensions. The application will not look like an IDE but we would have the flexibility to use JDev features (such as the wizards infrastructure, or the various viewers) in our applications
In other words, we would like the Eclipse RCP functionality and the ADF framework in a nice integrated package. Unfortunately, I don't think that this is going to happen any time soon. Otherwise, Oracle would have already made an attempt to create an ADF plugin for Eclipse...

Export Error on WebI Rich Client

Hi guys,
Is there any explanation or any suggested solution for the following problem..

JDev 11g: Task Flows,Rich Client- some questions to the Oracle team

Hello,
We're currently involved (early stages) in a large project with a Jan-Mar 2008 pilot delivery timeframe - one heavily including end-user customizable workflow elements, to which the aforementioned JDev/ADF 11 features would be a great fit.
Our plans so far were to go ADF with BC and include Shale or Spring WebFlow plus custom development to provide for the very same things that the feature-complete Task Flows will offer.
Questions:
1. Delivery timeframe - any unofficial pointers on the schedule for the next JDev/ADF releases?
2. Platform compatibility - Will the framework (ADF) run on J2EE 1.3 (OAS 10.1.2.x) or does it require 1.4+?
3. Design-time-at-runtime for Task Flows - Do we have it in the released bits? (Couldn't find it). Any pointers on how is it supposed to operate?
4. Am I right to think that what we're seeing with Task Flows is (among other things) a piece of the replacement functionality for the decommissioned Oracle Workflow subsystem (which bit us, by the way, as it was part of our original architecture).
5. Will Rich Client support older platforms than the currently supported IE7 and Firefox 2?
Thanks for any and all pointers,
Thanassis Stathopoulos
Athens, Greece

Thanks Shay,
http://www.oracle.com/technology/products/jdev/collateral/papers/11/newfeatures/index.html
Regarding my question 3 "Design time at runtime" - quoting from "JDeveloper 11g new features" at the above URL, under "ADF Task Flow". The third entry from the paragraph's end reads:
'Support for customization of task flows at runtime using "design time at runtime"'.
I was wondering what this is exactly - web-deployable editor to edit the flow definition after deployment?
Re your point 4, product replacement - with the feature set described in the paragraph above, Task Flows is much more than a Web UI controller. With "save for later", transactions, flow abstraction/nesting, BPEL outcalls, conditional logic, method calls etc etc it probably covers 50% of a typical workflow package and 75% of an embeddable workflow library (audit trail/timeouts/persistence nonwithstanding). This made me wonder whether it is part of a bigger, yet-to-be-announced OAS feature. Especially if one also considers the "design-time-at-runtime" sentence listed above.
Now, definition-wise, I guess it' s whether this feature set is considered half-full or half-empty :-)
Thanks again,
Thanassis

Doubts reg. Web Intelligence rich client.

Dear Experts,
I have seen in BOW310 Document "Web Intelligence Rich Client lets you continue to work with Web Intelligence documents (WID) when you are unable to connect to InfoView, when you want to perform calculations locally rather than on the server".
Now my Doubts are:
1. If we are not able to connect to InfoView then how will data come to WEB Rich Client in offline mode to perform the calculations?
2. Suppose Webi Rich Client is connected to the Server ie., in connected mode (not in disconnected mode) then calculations will be performed on the server or locally.
regards
Sam

Hello Sam,
If we are not able to connect to InfoView then how will data come to WEB Rich Client in offline mode to
perform the calculations?
The Webi Rich Client will allow you to work in offline mode if you have connected at least once to the relevant CMS. When you connect to the CMS, your security information is stored in an LSI file. It this LSI file that decides whether you have access to open a report.
When you're in offline mode (and have appropriate rights on the CMS), you will be able to
1. Create/ refresh documents if you have the appropriate universes and db middleware on your machine.
2. Only view, edit and save documents if you do not have the universes/ middleware. I.e. you can only work with data already saved with the report.
Suppose Webi Rich Client is connected to the Server ie., in connected mode (not in disconnected mode) then calculations will be performed on the server or locally.
This depends on how the Webi Rich Client (WRC) is launched.
1. If the WRC is launched via InfoView, then the WRC uses the same session as your InfoView session (no login is required), connects to the CMS over HTTP. All calculations are performed on the server.
2. If the WRC is launched locally (i.e. from the Start Menu / an icon), then communication with the CMS occurs via the CORBA framework. Your machine needs to have the middleware to connect to the DB and calculations are performed locally (on your machine).
Best,
Srinivas

Rich client & web services, how to avoid unnecessary bloat

Hi!
Im creating a rich client with java. From this rich client I need to consume web services. Now im wondering which web services framework to use in the client. It seems that almost all (axis, xfire, jax-ws) frameworks require 10+ dependency jars.
This I dont like of course because the rich client is going to be distrubuted over network and I would like to keep it as slim as possible. 5-10 MB in dependencies is not ok when rest of the program is 100k...
I guess that everything is going to be different in Mustang (it should include all the needed jars) but i need to support older versions for next x years.
So if anyone knows any suitable solutions please post here. Thanks.

The problem here is the SOAP engine running on Oracle9iAS 1.0.2.2 is a lower version than that running on Oracle9iAS 9.0.3/OC4J 9.0.3.
To get them to interoperate (e.g. 1.0.2.2 calling 9.0.3), you would have to do the following:
1. Build your Web service in OC4J 9.0.3/JDev 9.0.3
2. Deploy to 9.0.3 environment
3. Build a Web service client on the 1.0.2.2 environment, not using any 9.0.3 libraries (see below for a link to a paper to do this)
Conversely if you wanted to call from a OC4J 9.0.3 Web service client to a Oracle9iAS 1.0.2.2 Web service, you would have to do the following:
1. Build your Web service on 1.0.2.2 using 1.0.2.2 libraries
2. Deploy this to a 1.0.2.2 environment
3. Build a client to the 1.0.2.2 Web service using the 9.0.3 libraries
The reason it likely is not working is that it looks like you are mixing two different generations of SOAP libraries.
See the link below for how to build and consume Web services using Oracle9iAS 1.0.2.2:
http://otn.oracle.com/tech/webservices/htdocs/soapr1/ExploreSOAP1022.html
At the end of that paper is a link to another paper showing how to use JDeveloper 3.2 to build a Web service for 1.0.2.2 - it shows how to use its libraries versus the libraries that came with 9.0.3.

If I connect with the rich client "import document"is disabled.
if I try to create a new document from the rich client it returns the error below (I used the rich client on two workstations):

No data in webby using IE or firefox but data in webby Rich client

hi everybody,
I got a newbie probleme with BO edge XI r3.1 trial version.
If i create a report on webby via infoview usin a webby universe (efashion eg) , no text appear in my report, inluding data and text titles even i type something (structure is ok)
If i import this report on webby rich client, all the text appear. If i export on infoview and if i open my exported report via infoview all is ok. If i change my query and add something opn my report, all previous data stay but the new text doesn't appear....
Thanks for your help
Herve
ps Java version is the last one, and i run my trial on a windows xp sp3 via oracle virtual box. I used express install.

Seems Java version problem.
Can you change Display properties for existing and new query objects : "Read Cell Content as" to "HTML" and see ??
If you can, then use Java build less than 20 : JDK1.6.0_20 less to this like _17 or _18.
It solves your problem.
One more reason you are having multiple Java versions installed on your machine.
Work around:
Uninstall all installed Java versions.
When you are working on Infoview, to view WebI reports data , at that it will ask you for Java Virtual Machine Install, now install it, which works good now.
Thank You!!

WebI report in Rich Client refreshing - But not in the webbased WebI client

Dear experts,
I am quite new to BO and I am currently facing the following problem regarding our WebI reports:
I created a WebI report in the WebI Rich Client. This report accesses an OLAP universe, which in turn gets data from a SAP BW through a BI query. I also exported the report to the CMS. In InfoView, it is displayed correctly as well. The report displays the data alright.
Now here comes the strange part of it: When refreshing the report from within the WebI Rich Client, the data is being updated (the current BW data is being shown) as it is supposed to. BUT when refreshing the report from within the WebI Java client (in InfoView), the report would not update, i.e. it would not display the current BW data but instead the old data. When scheduling instance creation the instances would also not display the current data.
We are am running BO XI 3.1, no FixPacks.
Does anybody have a clue why this is happening?
Any hint would be appreciated.
Many thanks in advance!
Best,
Kai

Hi Ingo,
Many thanks for your reply!
The report would not refresh after I hit "Refresh data" ("Daten regenerieren" in German). Plus the newly created instances (one instance is being created every 5 mins) would also not show the current data.
The funny thing is that as soon as I go back to the Rich Client and hit "Refresh data" in the Rich Client, the report would always show the current data, never the old ones.
We should probably continue discussing in just one thread (Scheduled WebI report instances with differing values), this issue seems to be interrelated somehow anyway. Sorry for opening up multiple threads.
Thanks and best regards,
Kai
