Either ADD the java directory to your path OR

Change the batch file to include the full path where java is installed i.e. instead of
java -cp ".\reprap.jar;.\RXTXcomm.jar;.\j3dcore.jar;.\j3
d-org-java3d-all.jar;.\j3dutils.jar;.\swing-layout-1.0.3.jar;.\vecmath.jar;." -X
mx1024M org/reprap/Main
use
"c:\Program Files\Java\jre6\bin\java.exe" -cp ".\reprap.jar;.\RXTXcomm.jar;.\j3dcore.jar;.\j3
d-org-java3d-all.jar;.\j3dutils.jar;.\swing-layout-1.0.3.jar;.\vecmath.jar;." -X
mx1024M org/reprap/Main
Making sure of course that it is the proper path to JAVA on your system.]]> rhmorrison RepRap Host Fri, 05 Nov 2010 08:19:56 -0400 https://reprap.org/forum/read.php?12,65493,65493#msg-65493 Java problem https://reprap.org/forum/read.php?12,65493,65493#msg-65493
I'm running the lastest java on my Win7 64-bit system and I keep getting this problem

C:\Windows\system32>rem Amount of RAM to allow Java VM to use

C:\Windows\system32>set REPRAP_RAM_SIZE=1024M

C:\Windows\system32>rem reprap.jar file and stl file

C:\Windows\system32>set REPRAP_DIR=C:\Program Files\Reprap

C:\Windows\system32>rem Java3D and j3d.org libraries

C:\Windows\system32>rem set JAVA_LIBRARY_DIR=C:\Program Files\Reprap

C:\Windows\system32>rem cd so we can find the reprap-wv.stl file. Can we avoid
this??

C:\Windows\system32>IF NOT EXIST reprap-wv.stl cd "C:\Program Files\Reprap"

C:\Program Files\reprap>java -cp ".\reprap.jar;.\RXTXcomm.jar;.\j3dcore.jar;.\j3
d-org-java3d-all.jar;.\j3dutils.jar;.\swing-layout-1.0.3.jar;.\vecmath.jar;." -X

'java' is not recognized as an internal or external command,
operable program or batch file.

C:\Program Files\reprap>if ERRORLEVEL 1 pause
Press any key to continue . . .

Now I run 2 other java programs with no problems but reprap just don't want to run, can anyone help, java is not my cup of tea.

Thanks
