We had a team of 12 people all seasoned senior Java devs who learnt Grails from 0.6B and we are all still working on projects based on Grails. I wouldn’t go back to Java willingly, and we are all relieved to have broken the back of how to get somewhere quick with a Grails app. … Read more
Setting datasource { … logSql = true } in DataSource.groovy (as per these instructions) was enough to get it working in my environment. It seems that parts of the FAQ are out of date (e.g. the many-to-many columns backwards question) so this might also be something that changed in the meantime.
What finally worked for me (Grails now works smoothly) is doing almost like Steve B. has pointed out: JAVA_HOME=/usr/lib/jvm/default-java This way if the user changes the default JDK for the system, JAVA_HOME still works. default-java is a symlink to the current JVM.

In this case it should probably be cast to a clojure.lang.Associative, the highest common interface having the .containsKey method. Patch … Read more
What is Groovy on Grails? It doesn’t exist under this name anymore. It’s simply called Grails now. What is Groovy? Originally, a dynamic language for the JVM. However, since Groovy 2.0, both static and dynamic typing are supported. What is Grails? Grails (previously known as “Groovy on Grails”) is a programming framework based on Groovy … Read more
According to this SO thread, the solution is to use the non-primitive wrapper types; e.g., Integer instead of int.
There is indeed a Groovier Way. if (members) { //Some work } does everything if members is a collection. Null check as well as empty check (Empty collections are coerced to false). Hail Groovy Truth. 🙂
