I tried to run the NETrainCommand using the -server option, but I
received the following error:

Error: no `server' JVM at `C:\Program
Files\Java\j2re1.4.2_07\bin\server\jvm.dll'.

Does anyone know what I did wrong?

here's the command line I used:

java -server -Xmx512M
-Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser -cp
../lib/lingpipe_1_0_7.jar;../lib/xml-apis.jar;../lib/xercesImpl.jar
com.aliasi.ne.command.NETrainCommand -model=NCHFDL

cmb.xml cow.xml edu.xml fbc.xml gra.xml grg.xml lfc.xml mat.xml

Thanks!
