java not internal command of cmd.exe.

as command without file extension , without full path, windows searches first in current directory c:\blazeds\sampledb java.* find either java.com, java.exe, java.bat, java.cmd , other file extensions.

the file extensions defined in environment variable pathext separated semicolons can viewed in command prompt window command set pathext

if there no such file file name java in current directory, windows searches in directories specified separated semicolons in environment variable path. entering path or set path in command prompt window results in display of directories. (set path lists directories of path , file extensions of pathext both environment variables start string "path".)

the environment variable java_home needed perhaps java package , other applications, not read windows find executable file name java.

search directory containing java.exe , append directory of file path. on command line can done with:

path=%path%;full path directory containing java 

do not enter double quotes if full path directory containing java.exe contains 1 or more space characters.

or run java application command line

"full path directory\java.exe" -cp hsqldb.jar org.hsqldb.server
