The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Groovy vs BeanShell

Tags: groovy, beanshell, vs
I'm relatively new to using BeanShell, which I found was invaluable for writing quick'n'dirty scripts for a Lucene project. Groovy in scripting mode looks on the surface to be a replacement for BeanShell, but it compiles to byte code, which I guess means that it ought to be possible to make quick'n'dirty scripts a lot quicker because they do less work with Java reflection.

Is there a case for continuing with BeanShell or is Groovy simply "better"?

There is also (just to complicate things further) JRuby

http://jruby.codehaus.org/

Which has just got a compiler as well, so Ruby can be compiled to JVM bytecode

Personally, I currently use Groovy

From mayankeagle's first link:

> BeanShell the scripting language for Java and Groovy the dynamic, agile language for the JVM.

Concisely put and now I understand. It is funny that the definition caused so much upset in the comments at the bottom of the article.

From mayankeagle's second link:

> It's powerful. The ability to apply closures (unnamed blocks of code) to whole collections using commnads like Collection.each, Table.eachRow, and File.eachLine let you get a lot done in a few lines of code.

That *is* an attractive feature. I'm a big fan of inlining code to localise it so you don't have to keep flipping between modules. However, this mostly puts the spotlight on Sun's lack of foresight to provide support for closures in native Java... all eyes on Dolphin.

I'm interested to hear that TimYates is a Groovy user. I'll be lurking in this TA, hoping to get a sense of what it is like as a user, but only really out of idle curiosity. I think I'll be hanging in with BeanShell for my purposes, because my projects aren't naturally agile... and nor am I :-)

Thanks to both of you!
