Can anyone help me to convert decimal degree or degree/minutes/seconds to meters in Java?

How about GDAL?

GDAL is a translator library for raster geospatial data formats that is released under an X/MIT style Open Source license by the Open Source Geospatial Foundation. As a library, it presents a single abstract data model to the calling application for all supported formats. It also comes with a variety of useful commandline utilities for data translation and processing. The NEWS page describes the January 2011 GDAL/OGR 1.8.0 release.
