It maybe be having problems opening a display - try putting '-display :0.0' somewhere eg

* * * * * path to java/java StreamingSolution -display :0.0

You could need to reload the environment variable within your java script.

If your profile is ~/.bash_profile, which contained the classpath of java, to add these lines within your java script.

# Get the environment variable
if [ -f ~/.bash_profile ]; then
. ~/.bash_profile
fi
