DWR has a few restrictions:- Avoid reserved JavaScript words
- Methods named after reserved words are automatically excluded. Most JavaScript reserved words are also Java reserved words, so you won't be having a method called "try()" anyway. However the most common gotcha is "delete()", which has special meaning from JavaScript but not Java.
- Overloaded methods can be involved in a bit of a lottery as to which gets called, so avoid overloaded methods.
