classpath error

[Shiva Mohan]

I have downloaded JDK 1.5 and setted the environment variable as

.;C:\ProgramFiles\Java\jdk1.5.0_20\bin;

and I have created my first java program and put it in directory PP that direstory is created inside C:\ProgramFiles\Java\jdk1.5.0_20\bin.

now, in that commad prompt, i have given
set CLASSPATH
that gave result CLASSPATH=.;C:\ProgramFiles\Java\jdk1.5.0_20\bin;

now, I am at pp folder>javac JavaHelloWorld.java
it gives javac is not recognized......please help me

You have to modify System Variable - PATH - and put there link to the javac.
If you do not have PATH variable - create one.

[Ankit Garg]

This is not a ClassPath problem. Set the path environment variable to include

C:\ProgramFiles\Java\jdk1.5.0_20\bin

The classpath variable doesn't need to include this path...

[Shiva Mohan]

Thanks for the help, Lukas and Ankit.

After set
PATH=.;C:\Program Files\Java\jdk1.5.0_20\bin

i am getting the same error

C:\Program Files\Java\jdk1.5.0_20\bin\PP> javac
'javac' is not recognized as an internal or external command,
operable program or batch file.

You have to create PATH variable in the same place where CLASSPATH variable is defined.
After that you have to reopen your console - it takes PATH value when it starts.

as lukas said , we need to create "PATH" variable in "system variables" section.

also , put ";" towards the end.

[Shiva Mohan]

Thanks for the reply. I actually changed the CLASSPATH to PATH and already ; was at the end.

please note the my first java application is on pp directory and i have placed this directory in
c:\program files\jdk....\bin path

still,the error comes

[Ankit Garg]

I think you might have created two path environment variables. Try this on the console

set PATH=%PATH%;C:\Program Files\Java\jdk1.5.0_20\bin

Then try to run the javac command in the same console. Also I hope that your JDK is installed in the directory that you gave us i.e. C:\Program Files\Java\jdk1.5.0_20\ and there is a javac.exe in the directory C:\Program Files\Java\jdk1.5.0_20\bin...

Hi Shiva,
For classpath setting click here

[Jesper de Jong]

The problem could be that there is a space in C:\Program Files\...
Surround it with quotes, like this:

set PATH=%PATH%;"C:\Program Files\Java\jdk1.5.0_20\bin"

Note that PATH and CLASSPATH are two different things!
