(keitai-l) how to preverify from command line

hi all,

I am new to i-appli application development. I am using a Doja  emulator for
developing an i-appli application.
I am unable to preverify the classes from command line .Though I am able to
do  it from emulator.
Basically i am trying to use the  "-g:none" debug option .When I try to
download the application on to the device (mobile phone ).It pops the
message -- "This software contains an error "

I am using the following versions
j2me_cldc1.1  ,iDKDoJa3.0, and j2sdk1.4.1 all  are installed under  C:\
directory
----------------------------------------------------------------------------
--------------------------------------------------------------------
Steps which I follow to preverify are

Step 1.
-----
javac -g:none -bootclasspath c:\j2me_cldc\bin\common\api\classes  -classpath
C:\iDKDoJa3.0\lib\doja_classes;C:\iDKDoJa3.0\lib\classes;c:\j2me_cldc\bin\co
mmon\api\classes;.  Helloworld.java HelloworldCanvas.java

Step2
-----
move *.class compiled

Step3
-----
c:\j2me_cldc\bin\win32\preverify -classpath
c:\j2me_cldc\bin\api\classes;C:\iDKDoJa3.0\lib\doja_classes;C:\iDKDoJa3.0\li
b\classes;.;  -d preverified  compiled

Step3
-----
jar -cvfM Helloworld.jar preverified\*.class

I also changed the  JAM file before uploading .
