Hello, Thanks for your answers. One last question, do you know when the last port of Proj.4 C/C++ code to Java occured ?
Working in France, maybe you know Martin, that IGN France recently contributed to Proj.4 in order to update projection & transformations related to RGF93/Lambert93 (it's in proj.4 version 4-6-1). It's in this context that I plan to use GeoTools 2.5 via SDI. Using RGF93/Lambert93 when publishing datasets will be a legal obligation in France starting on Monday March 9th. In the mean time I have contacted the person in charge of RGF93/L93 project at IGN France in order to know whether they had validated GeoTools for this use or no. We'll see what his answer would be.
