Java builder error

[Vasilica]

I'm trying to wrap a program of mine to work with java. I tried a simple "hello world" first,

-hello world.m-

disp('hello world');

ant:

<mkdir dir="C:\work\hellopck\distrib" />
<mkdir dir="C:\work\hellopck\src" />
mcc -W 'java:hellopck,hellocls' -T link:lib -d C:\work\hellopck\src -w enable:specified_file_mismatch -w enable:repeated_file -w enable:switch_ignored -w enable:missing_lib_sentinel -w enable:demo_license -v class{hellocls:C:\work\hello.m}

java is installed same version with matlab java :

C:\Users\salas>java -version
java version "1.6.0_17"
Java(TM) SE Runtime Environment (build 1.6.0_17-b04)
Java HotSpot(TM) Client VM (build 14.3-b01, mixed mode, sharing)

C:\Program Files\Java\jdk1.6.0_17\bin>javac -version
javac 1.6.0_17

>> version -java

ans =

Environment variable is set:

>> getenv JAVA_HOME

Any help ?
