[Pljava-dev] A couple PL/Java questions

[Eric E]

Hi,
    I've been looking at PL/Java, and I'm pretty impressed so far.  I'm 
still unclear on a couple things:
1) Is is possible to write Java code directly embedded in the function 
are is all code in .jar files found in the classpath?
2) Is it possible to write a PL/Java function that returns a tuple with 
the number of of elements determined at runtime (to be used with a 
SELECT * from myfunc(arg);  )?

Thanks,

Eric
