I wonder if Oracle Jet is a framework or a library? On their website, Oracle said it is a collection of Jquery, JqueryUI and stuff as a library but I saw many people refers to it as framework. So which is correct?
It's actually more of a Toolkit. Thus the name, "JavaScript Extension Toolkit". You can use as little or as much of it as you like. If you use all of it, it would be similar to other frameworks. If you only use some of the UI components, they could be considered individual libraries I guess.
In the end, it's a toolkit that you can decide how to make the best use of.

I am starting to develop my very first joomla 3 component.
Should I choose legacy or native classes and why?
What about support in the future?
Joomla core components use Legacy classes. Are they gonna be removed in the future?
Thanks!
If you are starting Joomla! development right now, my opinion is to start using the legacy classes. From my knowledge, the legacy support will be in the next major release (3.5) as well in the current STS releases (3.1, 3.2).
What is going to happen in the future is rather a thing that will be discussed, software is evolving, so is Joomla.
You should learn using the legacy classes because:
you will find most of the documentation / books / support about them
core components are build using them (and understanding how core components work, is a key to your success in developing extensions).
Native classes:
are rather poorly documented
not so many examples (for example just the Joomla installer is using them)
not so many use them, so getting support might be rather difficult
it good to have a look at them one you have more experience with Joomla, so that you can understand the benefits
they don't have the powerful JModel that the legacy classes have, so building CRUD functionality will require more code to write and mentain
there are no clear rules on how the code should be organised, so this for a beginner may be confusing, not having a pattern to rely on.
Hope this helps.
I'm currently in an internship and i have to create a whole BI application.
I think i'll use pentaho, and I have to use just open source component.
I know that Pentaho Analyzer is not free
My question is: Is saiku an equivalent of analyzer?
If yes, can I use it with pentaho instead of analyzer?

I'm the developer of Pivot4J project and want to share my (subjective) opinion on the subject.
First, as though you righteously assumed Pivot4J to be more of an API than an application, it does not always mean you need to write lot of code to use it.
We also have a Pentaho BI plugin which does not require any coding and has comparable features to Saiku plugin, though it's targeted toward the yet unreleased Pentaho 5.0 platform.
And our sample application provides most of the functionalities that JPivot web application has, even though it lacks a data source configuration feature which will be soon to be fixed.
Compared to Saiku, I think each project has its own advantage in different scenarios.
Saiku has a much lightweight architecture on the client side than our sample application and the plugin, so it can be deployed and embedded virtually anywhere.
While it's not much difficult to create a full REST style analytic application with Pivot4J, our current sample and plugin applications require at least a Servlet container to run and are more difficult to be embeded than Saiku in certain environment.
On the other hand, as Pivot4J is designed to be UI independent API from the start, it could provide more flexibility than Saiku in my opinion to developers when they want to build their own application on top of it, or intend to customize core behaviors of the API.
For example, if you want to use Pivot4J with your own application which is build with ExtJS, DhtmlX, or any other UI toolkits, it'd be much easier to achieve a seamless integration with Pivot4J, as it provides you with convenient abstract extension points to do that.
Finally, if you're familiar with Javascript you might find working with Saiku easier as it delegates most of the UI related works to the client side.
On the other hand, if you're an old school Java developer like me :) you might find our sample application to be easier to understand and work with, as there's virtually no custom script involved and everything is done on the server side with JSF component model.
To conclude, I'd like to say that Pivot4J is not just an API which cannot be used without writing much codes as it already includes quite feature complete Pentaho BI plugin for the upcoming 5.0 release of the platform. And as Pivot4J and Saiku take rather different approach from each other, each has its own strength and advantage which could be leveraged to suit the specific use case.
Yes of course. Both the tools use the same underlying OLAP engine - Mondrian. Saiku is essentially the same as analyzer providing many of the same features - however it has a different architecture which additionally makes it very embeddable and pluggable. Plus Saiku can be used standalone too if you want to.
Check out the demo at dev.analytical-labs.com to see what it can do.
Also for help you wont find many tools with such a great community - hook up with them on Freenode IRC at either ##Pentaho or ##Saiku depending on your questions!
Pentaho is the right choice for OS BI too - Presume you looked at Jaspersoft as well? Worth a look but you'll no doubt realise the features are better in Pentaho.
Have you think about a pure javascript UI to pivot your olap cubes? There is one such component calls WebPivotTable at http://webpivottable.com
Jpivot, saiku and pentaho are all based on olap4j API so that they all need a java server side service. WebPivotTable use AJAX call to xmla service directly so that it can be used to pivot any xmla OLAP server, like mondrian, SSAS, iccube. Since it doesn't tie up with any java back end and also it is pure javascript based, you can easily integrate it into any website or web application.
I plan to make an web application using XPages for the design (plus the Lotus Notes Elements), but instead of storing the data in Lotus Notes, I will store the data in a RDBMS (specifically an Oracle Database). As you can see, I want to create a clear separation between the design and data. Is there a way I can do this? I mean, is there a way I can use Oracle as the data source and XPages/Lotus Notes for the UI only? Thanks a lot!
There actually has been native support for RDBMS/JDBC connectivity in Xpages since July 2011. Take a look at the Extension Library on OpenNTF (http://extlib.openntf.org/) and read the blogpost announcing the functionality: http://www.openntf.org/blogs/openntf.nsf/d6plinks/NHEF-8JYMXE.
It's not yet officially supported through IBM (not part of the Upgrade Pack 1 - http://www-01.ibm.com/software/lotus/notesanddomino/nd85-UpgradePack853-1.html), but there will be support for it in the future.
The short answer appears to be "yes but no" .
XPages is JDBC compliant, so you can connect to anything, including Oracle. The snag is, you'll probably have to write the code yourself. Apparently there are plans to open source a JDBC-based Relational Database XPages DataSource but there's been no activity as such. Find out more
XPages101.net may be a good site for cutting your teeth on Xpages. They have 60 lessons you can subscribe to. They are highly recommended. You may be particularly interested in lesson 55.
DISCLAIMER: I am not affiliated with XPages101.net in any way.
The XPages environment doesn't have any particular support for relational data sources, but there are two viable options depending on how cautious your organization is about using recent and beta software and how much support code you're willing to write.
For the former case, the XPages Extension Library (http://extlib.openntf.org/) is adding in relational database support for the 8.5.3 release of Domino, which is scheduled to come out at the beginning of next month. I'm not in the 8.5.3 beta, so I haven't seen this in action, but the video on their page looks promising and the Extension Library is high-quality in general. So if you're willing to deploy 8.5.3 when it comes out and use the Extension Library, it'll likely do just what you want.
If you won't be immediately upgrading or don't want to deploy the Library, you can write your own code using JDBC drivers; there's an example of this technique here: http://www-10.lotus.com/ldd/ddwiki.nsf/dx/xpage_integration_rdb.htm . While you can't, for example, just pass a RecordSet to a Repeat control on an XPage, if you're willing to write your own ORM, you could make your objects implement the List interface use Java-Bean-style naming, which would let you use them in standard controls and write expression language like "#{someRecord.someField}".
I'm looking for a set of Javascript based UI components for a web app I'm building and have found that many of the best looking web apps were built with the Capuccino framework; see http://www.getflow.com/, http://www.picsengine.com/home/ and http://timetableapp.com/ for examples.
However, I'm not a Cocoa developer and have no interest in learning Objective-J. Ideally, I'd find a set of components that provide the visual end result of Capuccino apps without the underlying weight of the framework.
I have seen the Aristo jQuery UI them (http://taitems.tumblr.com/post/482577430/introducing-aristo-a-jquery-ui-theme), but jQuery UI just doesn't seem to have the depth of components available in Capuccino.
I realize this may be a long shot, but I figured it can't hurt to ask. :)
Thanks.
As another option, there is jQuery UI: nice if you are already familiar with jQuery, with the plus side of not being too heavyweight, but may not have all the components you need pre-defined. A nice thing is that it encourages to write the HTML in a way that degrades gracefully when your application in older browsers.
Maybe sproutcore is an alternative for you, although it requires you to hand-code everything in javascript from scratch. It offers most basic components and is easily adjustable to your personal design goals. Sproutcore is used in Apples Mobile Me and in some other big projects.
Another possibility might by vaadin which offers a rich set of prebuild controls and is based on Googles GWT javascript compiler. But it only makes sense if you are developing in a java environment.
Can anyone recommend a GUI builder tool for creating DHTML web apps using AJAX to communicate with a web service backend? I'd like to avoid having to mess around with designing HTML, marshalling/unmarshalling data, checking for browser compatibility, etc. The tool should have a library of widgets that can be put into an application and hooked up to functionality, and be extensible enough to be able to define custom widgets. Of course free and/or open source is preferrable but I would consider proprietary tools too.
Also to what extent does the choice of GUI tool affect what platform or language I would use for the backend? If the GUI is just calling a web service then I should be able to use anything on the server-side to provide that interface but maybe some gui-side tools use a proprietary data exchange format that requires some specific server-side code?
Edit: I don't need a widget that can be dragged, I want an IDE that allows one to build a gui easily (i.e. a RAD tool).
WaveMaker is open source, runs on J2EE.
If you're comfortable with Java, maybe you could try Google Web Toolkit? http://code.google.com/webtoolkit/
I'm using Wavemaker and it does exactly what are u asking...
It is really easy to use and very perfomant....
I believe Dreamweaver does some of this, but in my opinion such editors are not a good idea. They produce horrible, unmaintainable server-side code and are quite inflexible.
Wavemaker beats everything else I have used hands down. Applications can be developed rapidly, has drag and drop, can connect to any web service, and has unmatched database management tools. The only problem with it is that it has kept changing hands/ownership so much and its future direction is not clear.
Delphi for PHP from Codegear has some of this capability, but I would agree with ceejayoz that such tools don't necessarily make for nice code.
On Dan's suggestion I took a look at GWT. I'd heard of it before but never looked at it that closely and it seems pretty interesting. Certainly it takes away the annoyance of pixel pushing and making things work in multiple browsers. I also tried searching for "gwt rad tools" and came up with a couple of results:
Instantiations GWT Designer (commercial, $59/year)
Wirelexsoft Vistafei (still in beta but will have a free and a commercial version)
I'll take a look at these but if anyone's used something else let me know.
