It may be not compiled?

It is already compiled.

Using your data and script, I got the results of the estimated plane.

        Nz =                 -0.002866284759                 +0.000745242995

Do I use JavaW or JavaC ?

No, javaC ist the java compiler. The javaw command is identical to java, except that with javaw there is no associated console window. Use javaw when you do not want a command prompt window to appear.

Please remove the rem in the last line to execute the pause command to get the error message, i.e.

rem ARGS: {ELLIPSE3D/CIRCULARCYLINDER/CYLINDER/CIRCLE3D/PLANE}  LVERM  POINTS  REPORT
java -jar FormFittingToolboxConsole.jar PLANE 0 PLANE3d.txt PLANE3d.out
