I have a Groovy script that converts some very poorly formatted data into XML. This part works fine, but it's also happily passing some characters along that aren't legal in XML. So I'm adding some code to strip these out, and this is where the problem is coming from. The code that isn't compiling is this: def illegalChars = ~/[\u0000-...
I want to read a webpage A in ISO-8859-1 charset, according to the browser, and return the content in UTF-8 as a content of the webpage B. This is: I want to show the content of the page A in the same charset that I use to show the rest of the page B, that is UTF-8. How do I do this in java/groovy? thanks in advance ...
The following Groovy commands illustrate my problem. First of all, this works (as seen on lotrepls.appspot.com) as expected (note that \u0061 is 'a'). >>> print "a".matches(/\u0061/) true Now let's say that we want to match \n, using the Unicode escape \u000A. The following, using "pattern" as a string, behaves as expected: >>> pri...
I have some resources I must access with SSL that use self-signed certificates. In general, most tools have a simple setting to allow these to be accessed without error or just a warning. However, it seems like the proper way to do this with the JVM is to import the signing certificate into a keystore as a CA. I have a groovy script I...
By default SomeController.groovy has a controller name of some. Also, pkg.SomeController has a controller name of pkg/some. Is there a way to plug a custom mechanism for this translation. In my particular instance I want to get rid of the pkg (it's a long story why I need this) I can try to use @Controller("name") but given the number ...

So we have some unit tests written in groovy. We have the Groovy Eclipse plugin going, we have gmaven going, but the problem is that the maven eclipse plugin doesn't automatically add the src/test/groovy directory as a source directory. So, I enlisted the build-helper plugin to add a source directory, but then the problem becomes the sou...

I would like to develop some apps for the JVM using a concise, dynamic language. The most popular choices for this seem to be Jython, JRuby, Groovy, and maybe Clojure. Rhino appears to be fast and very stable, but I see no books on Rhino development and little discussion. Why is there apparently little use of JavaScript for other than e...
I have been maintaining a maven java project for year. Recently, I learned Ruby and asked why haven't these nice features (of Ruby) existed in Java, and I am so happy to find Groovy the answer. It's already out there for more than 6 years and what a shame I didn't know about it sooner. Now come to the story: I have a lot of java code wri...

Use Case: Take an HTML file with comments in a specific format (a format I specified), and change it to a JSP page that fills in these special areas with custom JSP code. Simple Example: <html> <!-- start:custom-title-content --> <h1>this is the generic title content used to develop the HTML page</h1> <!-- end:custom-title-content --...
I have a test grails app setup with a context of "/testapp". When I add a link in my gsp that references / it does not go to the root of my grails.app.context, but to the root of my grails.serverURL property. For example given a link with href "/css/main.css" I would expect that this link would actually look in localhost:8080/testapp/c...

I have two java projects, A and B, A depends on B. In project B I've added a groovy class (Foo.groovy) and a java class (Bar.java) that uses the groovy class. In MyEclipse, Foo.class is in bin-groovy, and I can run things from MyEclipse just fine. However, when MyEclipse deploys project A to tomcat, it does not include the Foo.class file...
