I have been reading Groovy, and I'm half way down. I started to love groovy a lot, and apply it to solve some simple real world problem; As I love building web applications, i would go for reading Grails webframework as I know Groovy.
But If I want to build desktop-applications, which framework will be the good choice? I wanted to create a simple IDE for Groovy language(or say for any language), that can do syntax highlighting and other kind of stuffs.As mentioned earlier, I love Groovy a lot when compared to Java; And Griffon is a framework that is built on Groovy, mainly for creating Desktop-appplications. But I didn't find enough resources for Griffon!
Is Griffon is the good framework for those people who know and love Groovy(as I do)? Can I choose it for building a simple IDE as mentioned above? Or there are any other framework that is built on Groovy, which is good when compare to Griffon?
The problem I have found with Griffon is that a number of the plugins are a bit out of date in that they aren't using the latest UI libraries (e.g. Flamingo, Substance, and SwingXBuilder, altho I think this has just been upgraded to use SwingX 1.6).
I am using SwingBuilder directly, with a few extensions I have added via my own builder implementation:

If you want to build an IDE I can recommend the RSyntaxTextArea component, as it has great support for many programming languages and is pretty simple to use:
http://fifesoft.com/rsyntaxtextarea/
Griffon is a fairly good MVC based framework, and is built on top of Java Swing. So it can do anything that Swing can do.
To be honest I found Griffon a little too much for relatively simple UIs, so I usually write my apps in Groovy using SwingBuilder directly.
If you really want to get into Griffon I recommend getting the Book
Griffon in Action It seems to be the only place where everything is documented, although the web page is coming along and improving all the time.
There are definitely various resources out there that will let you learn more about Griffon, for example the Griffon Guide -> http://dist.codehaus.org/griffon/guide/index.html
"Griffon in Action" is another popular resource which you can buy in electronic form today; being the author of both makes me a little biased ;-)
You can keep up to date on Griffon news by following the mailing lists and #theaviary on Twitter

i have to do a DSL and an interpreter of it using Eclipse modeling framework i think so , because i dont have a lot of information about it . I have four months to do it and i am very lost .
The DSL have to read files from sensors , and with the DSL you can make complex math operations . Anyone one know any free resource/book/tutorial/guide where i can read about that ( i can't find anything useful) or anyone can tell my some clues to follow and how start . Thank you so much.
I try to find some examples doing someting like that and i can't find anything.
Eclipse Modeling Project: A Domain-Specific Language (DSL) Toolkit and EMF: Eclipse Modeling Framework (2nd Edition) are two great books on this topic that you can get used for about five dollars each. While not free, they are well worth the small price. There is also a newer reference Implementing Domain Specific Languages with Xtext and Xtend that seems very relevant but I have not had the pleasure of reading it yet, so can't vouch for it.
There are also many free talks on these subjects on youtube and all the EMF, Xtext, etc. websites have quite a bit of tutorials.
Also, based on this question: Interpreter vs. Code Generator Xtext , Xtext does not appear to support interpreters but Xbase may.
There are examples of using XText to build an interpreter / interpreted language (eg. https://eclipse.org/Xtext/documentation/202_scripting.html).
For me, it took a while to get all plugins configurations correct, but it is well documented, on Xtext web and in github / tutorials.
Also, look at XTend (http://www.eclipse.org/xtend/) as this is a major birck in XText framework.
I'm working on a product which is an RCP application based on Eclipse 3.x api. Now we are trying to move it to Eclipse 4.x. We are using some internal classes in our code. I've already read the tutorial provided by Vogella about migrating to Eclipse 4.x from 3.x, but I'm still not getting how to start.
We want to take advantage of the new Eclipse features, my main question is that we have good number of views, layouts in our old code, so what should be the approach I should follow. Also is there a way to create an application model from my older application using 3.x API.
I'm stuck and not getting how to proceed.
this really depends what you are trying to do. Do you just want to update your IDE? Or should the project be based on the e4 platform.
I recently updated a project from 3.x to the new IDE. This works very good, the compatibility layer does a good job and you are able to run the application with minimal changes. However if you do this, you cannot use the benefits of the e4 platform.
If you want to move your application to e4, thats more work to do. Mostly you will not want to touch all the old code, so there is a possiblity to have 3.x and e4 plugins run together in your application. Thats done with the e4 bridge and wrapper classes for old code. Most of the IDE views and editor are also still based on 3.x, so if you use them, the e4 bridge is also a good way to incorporate them.
Some information can be found here:

I've read both the tutorial.But I am stucked and got too much confused as to where to start from. Basically 3 features are there
1. css styling of widgets(which i understood and did a bit of it)
2. to introduce dependency injection in my code
3. to put the application model
What approach I should follow?
This document helped me in deciding which strategy to adopt. http://www.eclipse.org/forums/index.php/fa/17403/ for migration.Indicates clearly which strategy you should adopt based on your existing code structure.Hope it helps
Have anyone tried to write a Netbeans RCP application in scala (Instead of Java). The reason for my question there is an API in Scala which wraps JavaFX. Likewise is there any API to make to develop Netbeans RCP based apps written in scala.
For wrapping JavaFX there is ScalaFX. Netbeans Rich Client Platform is not small, and a Scala wrapper seems impractical to me (I am not aware of any); just call the Java code from Scala. Java/Scala interoperability is generally decent, so while you might occasionally have to write a little bit of Java as an interface, you can pretty much just use Scala for any Java project.
(Getting the build process to work might be a little tricky, though; expect to invest a little time there.)
I personally dont see any useful use case to use JVM language to develop NB RCP/Plugin. NB It self provides a IDE where you can use the drag-drop feature, codegen, annotation based IDE to created it. If you want to have a syntax sugar in writing NB RCP then i feel its waste of time where we already have a good IDE. JVM is not going to do any much difference that the existing environment.
If you see that you need a NB like modular, GUI based framework in Scala ecosystem that, I personally feel writing binding wont solve that problem. Scala need some framework like Griffon.
I am a newbie to AspectJ and to learn it I am trying to search for some open-source simple applications that use AspectJ for the web but I am unable to retrieve any. I am trying to build a filter through this technology but I am not able to find any working examples that are suited in particular to Eclipse/Tomcat.
You can get (many variations) of a simple e-commerce application built using Spring+AspectJ from http://manning.com/laddad2 (click on "Source Code" link).
Not sure they're specifically targeted at Tomcat, but the examples at
Eclipse AspectJ Sample code ought to give you a start.
Is it possible to create Eclipse plugins/program Eclipse RCP apps without Java? (preferably in Jython)
This will be possible in the next Eclipse major release e4:
One of the goals of e4 is to provide support for writing plugins in other languages.
The quote is from http://wiki.eclipse.org/E4/JavaScript which summarizes the current state of using javascript to implement eclipse plug-ins in e4.
This issue in eclipse's bugzilla issue #227058 also has some discussion on that, but I believe it is outdated.
I am currently not aware of activity regarding other languages.
No. An Eclipse plugin is an OSGi bundle, and that requires interacting with a variety of things that can't implemented in Jython as far as I can see.
If you want to avoid Java, you can look at other things that target the JVM, but you will have to figure if you can produce and consume the specific items needed to call the necessary things and be called in the necessary ways.
OSGi bundles may be written in other JVM languages like Scala. Eclipse plug-ins, as of now, does not support any language other than Java. The Eclipse Plug-in Development Environment heavily makes use of JDT which ties it to Java. However there are some plans I heard that plug-ins might be supported in other languages. But I don't see that coming in near future.
You can write your main code in Jython and use Java interfaces to call then from Java. Take a look at this for details. Also, I am writing a utility library (github.com/abhin4v/jywrapper) to do the same. It has very little documentation right now, but you can look at the examples provided.
