How do I convert a Java byte array into a Scala byte array?

Question

I am new to Scala and work currently on a project involving both Java and a Scala modules. Now I\'d like to call a Scala method from Java using a parameter of type byte[].

I tried to reproduce your error but it ran as expected. Running with scala 2.9.0 and sbt

java code:

package stackOverflow;

public class ByteContainer {

    private byte[] bytes;

    public ByteContainer(byte[] bytes){
        this.bytes = bytes;
    }

    public byte[] getBytes() {
        return bytes;
    }

    public void setBytes(byte[] bytes) {
        this.bytes = bytes;
    }

}

scala code:

package stackOverflow

import stackOverflow._

class ScalaByte{
    val bytes:Array[Byte] = "this is my test".getBytes()
}

object ByteUser extends App{
    val b = new ByteContainer((new ScalaByte()).bytes)
    val s = b.getBytes()
    println(s)
}

output: [B@6ef38f6f

This compiles and runs. Is this not what you were asking about? feel free to comment.
