Seems your java environment is not correct.
Try running "java -version" is that working ok.
Check your environment with "set" is JAVA_HOME set, and ANT_HOME ? 

Remember to put %JAVA_HOME%/bin on the environment PATH setting.
That should be it.

Subject: Ant won't run, help interpreting output needed

I have used ant on several occasions in the past, installing in on three or 
four computers. I just installed it on my workstation at a new job this 
morning. I have a build.xml file in the directory from which I call ant, but 
with or without the build file, I get the following. Can someone tell me where 
I've gone wrong? Thanks.

=================================================
H:\dev\java\XMLfromSPOOL>ant
Usage: java [-options] class [args...]
           (to execute a class)
   or  java [-options] -jar jarfile [args...]
           (to execute a jar file)

where options include:
    -client       to select the "client" VM
    -server       to select the "server" VM
    -hotspot      is a synonym for the "client" VM  [deprecated]
                  The default VM is client.

    -cp <class search path of directories and zip/jar files>
    -classpath <class search path of directories and zip/jar files>
