关于GeoTools的 Can't load a service for category "MathTransformFactory"解决方案

最近在使用GeoServer做GIS开发,使用过程中就出现了设置投影的时候,报出了标题上的错误。很郁闷……

publicCoordinateReferenceSystemSetC()throwsIOException{
Stringwkt=
"PROJCS[\"UTM_Zone_10N\","+"GEOGCS[\"WGS84\","+
"DATUM[\"WGS84\","+

try{
CoordinateReferenceSystemcrs=CRS.parseWKT(wkt1);
returncrs;
}catch(FactoryExceptionparse){
throw(IOException)newIOException("UnabledtoparseWKTEXT

wkt).initCause(parse);
}
}

Inline...CRS.parseWKT(wkt1)wascatchedexception.

最后才发现:


少拷了两个与其相关的jar包:jsr-275-1.0-beta-2.jar和vecmath-1.3.1.jar。把这两个jar包拷贝到bin目录下就没有问题了
