My preferred approach is to store pointers as Object (and access some field via index), which has the advantage that you can't fiddle with the pointer from the Java-side in any way. Of course, using a long is slightly more clear. For the access of the pointer I prefer to pass it directly via the method arguments. This avoids all the find* blah stuff. If this ain't possible for some reason it is advisable to only do the findClass stuff once and store the indices in some variable (IMO). /Roman -- “Improvement makes straight roads, but the crooked roads, without Improvement, are roads of Genius.” - William Blake
