Look into "Java Number Cruncher: The Java Programmer's Guide to Numerical Computing" - Chapter 12.5 Big Decimal Functions : there is some source code with as exact as possible algorithm to compute exponential and logarithm.

Using the mathematical formula : x^y=exp(y*ln(x)) you can achieve a result with maximum precision.

Nevertheless doubles do have a good precision and I strongly recommand you test if it's not precise enough for your need.
