I am writing my first taglib as part of a plugin and I would like to document it. Adding javadoc (is there any place that documents groovydoc or is it really the same thing?) doesn't seem to work for non-methods. Specifically, is it possible to document the def mytag in: /** * This doc shows up */ class MyTagLib { static namespace ...

Hi, I'm working on a XML-document with Groovy and test a node for a certain attribute, which has a namespace prefix. How could it work: in groovy-script: ...

I'm able to run Groovy scripts from Groovy using proc = "cmd /c groovy BillingServer.groovy".execute(null, new File("C:\")) However, I can't find a way to then terminate/kill the process. waitForOrKill(1) and destroy() "act" like they've worked, but the external process continues to run. Calling exitValue() fails with java.lang.Ill...
Let's say I have an existing application written in Java which I wish to add scripting support to. This is fairly trivial with Groovy (and just as trivial in .Net with any of the Iron range of dynamic languages). As trivial as adding the support is, it raises a whole host of questions about script execution and security - and how to imp...

Hi, As a "learn Groovy" project, I'm developing a site to manage my media collection (MP3, MP4, AVI, OGG) and I wasn't able to find any open source library to retrieve meta data from this files. I was thinking of something like Linux's file command. I've found few libraries on Java that do one or the other (like mp3info), but not a tota...
Hi I'm looking to parse spreadsheets (xls/ods) in Groovy. I have been using the Roo library for Ruby and was looking to try the same tasks in Groovy, as Java is already installed on a development server I use, and I would like to keep the number of technologies on the server to a simple core few. I am aware that the ods format is zipped...

I use GORM to generate my database's DDL from groovy classes. Which is great. However, the order of fields in the generated SQL is not the same as the order of fields in the class. For example, if I create the class class Person { String firstName String lastName String address String email } the following SQL is generated ...

I'm looking to run some un-verified scripts (written in a yet-to-be-determined language, but needs to be Java-based, so JRuby, Groovy, Jython, BeanShell, etc are all candidates). I want these scripts to be able to do some things and restricted from doing other things. Normally, I'd just go use Java's SecurityManager and be done with it....
Is there some way to use default parameters values with closures in Groovy? This is what I tried so far: class Persona { String name Persona( String name ) { this.name = name } String salute( String salute = "Hola" ) { salute + ' ' + this.name } } Persona.metaClass.salute2 = { String salute ...
