[java-gnome-hackers] jcharArray, jbyteArray, jstring

[Mark H. <mh...@ti...>]

Hi,
  I've been trying some of the other applications again and coming into
yet more problems which I assume to be related to passing byte arrays.
I'm not entirely sure why I'm encountering them and noone else is - I am
just using normal english and even the same source files in some cases.
I guess it must be a difference between kaffe and java.
The latest methods I've found problems with are for new Gtk Labels and
Frames. 
This is all autogenerated code:
JNIEXPORT jint JNICALL Java_org_gnu_gtk_Label_gtk_1label_1new (JNIEnv
*env, jclass cls, jbyteArray str) 
{
  jint str_len = (*env)->GetArrayLength(env, str);
  gchar* str_g = (gchar*)g_malloc(str_len + 1);
  (*env)->GetByteArrayRegion(env, str, 0, str_len, (jbyte*)str_g);
  str_g[str_len] = 0;
  {
      return (jint)gtk_label_new (str_g);
  }
}

I've found that changing it to this fixes the problems (for me at least)
JNIEXPORT jint JNICALL Java_org_gnu_gtk_Label_gtk_1label_1new (JNIEnv
*env, jclass cls, jstring str) 
{
  const  gchar *str_g = (*env)->GetStringUTFChars(env, str, 0);
  {
      return (jint)gtk_label_new (str_g);
  }
}
Is this the best way to handle it?
