Adding Labels to a Vector Map with Java Mapscript

[Alejandro Rico]

Hi all!!

Working in my problem with the labels, i see  that is needed to set the
minSize and the maxSize to the labelObj object, and with the following lines
all work fine:

Etiquetas.setMaxSize(256);
Etiquetas.setMinSize(4);

thanks to all of you for your help !!!
