hi , is there anybody who run java programs in SciTE editor. i have downloaded this from http://www.scintilla.org/SciTEDownload.html. somebody suggested this in this forum and also suggested how to run java programs in this editor.but when i tried to compile ...i got message "javac squareroot.java (of course ,this is my source file) file cannot found".

forum suggestion was to set up the correct path(enviornment variable). but unfortunately i am not able to do that. i went to the control panel>system>advance>.....>path. and clicked edit and got a small window which contained

variable name : path
variable value: %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem

what should i do now??? let me tell u also my java compiler is in c:\
i.e c:\java\bin .......so i tried like below..

variable name : path
variable value: %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem ;c:\java\bin

then clicked ok. i saved my squareroot.java in f:.then i compiled but got the same message.... plzzzz help to fix this...

this editor is interesting. generally i run my program from command line by going to bin directory writing on a notepad. i have sun java 1.4.1 and win-xp system.

thanks

 If you are running your editor using command lien I think you need to restart your cmd window.

This problem may be caused by your editor. For example UltraEdit32 supports many programming language text highlighting and many other things including running commands, such as javac.
  First I set up the system variable - PATH (you already done this)
  Then set the command line I would like to use: javac -deprecation %P%n.java
( two variables have their meanings: %P - currently edited file path (DOS format), %n - file name (Windows format)
  And it works fine.

This was only an example, I also had such a problem. I don't use SciTE editor, but I think you should read about parameter passing and internal command running in editors help more aqurately

is this setting correct??

 variable name : path
variable value: %SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem ;c:\java\bin


plz note...my java is in C:\java\bin   and source code is in  F:\

i  DID NOT RESTART the editor.... i will check this

i simply clicked on the compile menu  after writing the source code....and saw a vertical window to come up where it says " javac squareroot.java (of course ,this is my source file) file cannot found".

> is this setting correct??

  It seems correct given that you have installed java in the c:\java folder.

> where it says " javac squareroot.java (of course ,this is my source file) file cannot found".

  It should say: "javac f:\squareroot.javafile"

  Is there any way to tell your editor explicitly where to find the source files?

you'll need to restart the editor to pick up the PATH changes.

It tells the OS where to search for programs, in your case javac.

When you type javac (or any command), the OS searches the directories in the PATH to locate where the javac executable is on your file system.
