Pass Scala Seq into Scala function from Java

Question

I have been smacking my head against the table for hours. I am trying to call a function that is written in a library that takes Seq<Object> as the only argument type. The problem is, I can't seem to be able to construct anything that Scala wants to recognize as a collection type.

I've tried everything from using Scala Buffers and the like and trying to convert to a Seq or using the $colon$colon stuff. Nothing works can someone please point me in the right direction.

EDIT:

This is the code I'm using at the moment

    List<Object> objs = new ArrayList<>();

    Object obj = new Object();
    objs.add(obj);   

    function(JavaConversions.asScalaBuffer(objs));

Which has no errors but I receive java.lang.String cannot be cast to [B

I omitted some arguments to new Object() since it is sensitive data

thanks

Answer 1

java.lang.String cannot be cast to [B means you're trying to pass a String to a method that calls for a byte[] (that's what [B means).

Try calling getBytes on your String and that should fix your problem.

(Note: It appears your problem has nothing to do with the code you posted. Maybe it's in the "sensitive" part that you removed.)
