first of all, you got your classpath in the wrong spot, it should be declared before you name the class to be executed.

secondly, you cannot set a classpath to a class file, only to directories which hold class files, or jars and zips which contain class files.

So, in your case, you would do:

java -cp C:\ Test

the explanation is: the classpath is set first, to the directory C:\ since that's where your Test.class file is
then you just have to name the class by itself, without any folder information since you set the classpath to find it in correct location.
be advised, the class name is case sensitive, so if it really is named "test.class" just write "test". But typically class files
have first letter capitolized.

Pls help me to solve this problem, thanks !

java -cp classpath c:\j2sdk1.4.1\lib\tools.jar;C:\ c:\test

Try
java -classpath .;c:\j2sdk1.4.1\lib\tools.jar test

put your .bat file in the classpath and try it from there first.

My .bat file (that works):

C:\JavaTools\Test>type maptest.bat

c:\j2sdk1.4.0-rc\bin\java -jar ..\MappingClient.jar

I have my classpath always set correctly when system boot:

my envoronment variables look like the following:
classpath C:\j2sdk1.4.1_01\lib\tools.jar;C:\j2sdk1.4.1_01\lib\mail.jar;C:\j2sdk1.4.1_01\lib\activation.jar;C:\j2sdk1.4.1_01\lib\imap.jar;C:\j2sdk1.4.1_01\lib\mailapi.jar;smtp.jar; C:\documents and settings\damien\desktop\java;.;

to set classpath on you system, right click on m computer, properties -> advanced -> env variables...
and there, add a varaible called classpath and put in it the things youwill ned (note on mine, I had to manually put mail.jar, activation.jar, and the directory on my desktop from which I run the java class and where the batch file that runs it is saved)

now, if I want to run a class that is in my C:\documents and settings\damien\desktop\java folder, I just create a .bat file that has the following in it and save it in the same folder.

java classname


that's it

you can't do -cp and classpath!

just use -cp. If you want to include the environment variable classpath then do %CLASSPATH%
