It's java.lang.NoClassDefFoundError
Do a search on thsi board first, usually adding . to the CLASSPATH would help, i.e.
> set CLASSPATH=.
or
> java -cp . Test

Otherwise, please show us the results of the following:

> echo %JAVA_HOME%
> echo %PATH%
> echo %CLASSPATH%
> rem X is the drive letter where the java source is
> X:
> rem YourFolder is the folder where the java source is
> cd doc
> dir
> rem YourClassName is the class name
> javac Test.java
> java Test
