There are several alternatives to Grails:

• JRuby is an alternative to Grails. Grails uses Groovy as the language, whereas JRuby uses the Ruby language


• Jython -  implementation of Python in Java


• Rhino - JS Scripting language included by default with Java 6 SE. See the VisualBuider Java 6 tutorial.


• Scala - based on academic papers not as popular as Groovy but with some powerful features such as strong integration with Java and very good XML processing features. Look out for a future VisualBuilder.com Scala tutorial.

Examples of the different scripting languages:

Ruby File.

foreach('visualbuilder.txt', 'r') do |line|    

  puts line  

end 

Scala

import scala.io.Source  

for {  

    (line) <- Source.fromFile("visualbuilder.txt").getLines  

}

print(line)

Rhino

lines = readFile("visualbuilder.txt").split("\n");  

lines.pop(); 

for (i in lines) {  

    print(lines[i]);  

}

Groovy

new File("visualbuilder.txt").eachLine { line ->

    println line  

}
