Why is conversion from array/vector of chars to jcharArray not working?

Question

This really is an array/vector of chars, not a string (i.e. not a char* string).
jcharArray convert(JNIEnv* env, const std:vector<char> vect)
     int size = vect.size();
     jcharArray arr = env->NewCharArray( size );
     env->SetCharArrayRegion( arr, 0, size, ( jchar * ) &( vect[ 0 ] ) );
     return arr;
}It returns garble to Java instead of the characters put into the vector. What am I doing wrong?

Answer 1

Presumably you have some reason to think that vect[ 0 ] is going to represent a contigous memory segement for the rest of the characters.
A java "char" and C "char" are not the same size.
