I attended the Groovy = Java Tech + Ruby + Python for the JVM session. This is a simple equation that makes a lot of sense to me, especially since I develop a lot of Groovy scripts at work. This session was a 101 introduction to groovy. Rob Cope of OpenLogic did a great job at describing the dynamic aspect of Groovy, Closures, Groovy Markup builders such as AntBuilder and XmlBuilder, and the the GDK extensions.<\/p>\n
For those not familiar to Groovy. Groovy is a object-oriented dynamic language that runs on the JVM. In Groovy, static typing and semicolons are optional. Groovy has a lot of built-in features missing in Java, such as regular expressions. A great feature of groovy is that it compiles to a class file which can be used in a Java application. According to Rob, “your boss can’t tell if you are using Groovy.”<\/p>\n
The one feature of Groovy that I was not at all familiar with was the Scriptom. Scriptom gives you access to COM objects, in a fashion that is similar to VBScript developers. Rob shows demoed Scriptom, he opened Microsoft Excel added values, created a chart, saved the chart to the file system, created a JFrame with a button that use the chart as an icon. More amazing is that he did this without restarting or closing or rebuilding anything.<\/p>\n
I am seriously thinking of replacing all our VBscript dependencies from our application. We use VBScript to open and print Word and Excel documents. With Groovy and Scriptom I could do this in the JVM.<\/p>\n
