If javac isn't recognized that means you have to set the path. So at the command prompt type set path="C:\Program Files (x86)\Java\jdk1.7.0\bin";
after setting this path you can compile your programs.

with the ; token?
(thanks hope it works out!)

EDIT: thanks so very much in a 5 mins i got the solution from ya! thanx!!!

Most welcome

it worked all fine, but i restarted the prompt, and i need to set the patch again? solution for this?

If you set an environment variable (such as the 'path' variable) in your running cmd.exe, the changes are local to that session; if the session terminates the changes are lost. You have to press the 'start' button and find the dialog somewhere to make those changes permanent.

kind regards,

Here's one way on XP:
The PATH environment variable is set from the Settings | Control Panel | System panel.
Select the Advanced tab and
Click on the Environment variable's button.
At the bottom in System Variables, find the PATH entry and click the Edit button
Add the new path using ; to separate it
Its a stupid small text field so be careful.

hey, just try this....
Right click on mycomputer->properties->advanced->environmental varibales->user varibles->new->give variable name:path and variable value:C:\Program Files (x86)\Java\jdk1.7.0\bin;c:\windows\system32;
now the path will set permnently and you can run the java program any where in your system.

i readed it somewhere indeed, but you are the first with exact codes.
but your way dint work, but it solved an problem now. thanks, evryone problem solved!
