> It's relatively straight forward to call static functions in JDK using

> select reflect("java.lang.Math", "max", 2, 3) from mytable limit 1;

> However, how do I use reflect to call non-static functions (e.g., indexOf()
> method in java.lang.String class)?
> None of the following usage of reflect is correct. Assuming that mytable

> select text, reflect('java.lang.String', 'indexOf', 'school today'),
> reflect('java.lang.String', 'indexOf', text, 'school today'),
> reflect('java.lang.String', 'indexOf', 'school today', text)
> from mytable
