Check your environment variables:
I posted this in a previous thread:

Considering you have windows:

Goto start--->right click on my computer--->select properties
Goto the advanced tab, and you should see a button at the bottom that says environment variables...click on that.

The only thing you need to worry about is the PATH variable, and the CLASSPATH variable, nothing else.

SKIP THIS STEP AND GO ON TO THE CLASSPATH, IF IT DOESN'T WORK AFTER SETTING THE CLASSPATH, THEN COME BACK AND SET THIS.
The path variable must point to the bin folder in the sun app server, and the bin folder in the jdk directory. Now, those are two different directories, so you seperate them with a semicolon when creating it. Here is what mine looks like:

C:\Sun\AppServer\bin;C:\Program Files\Java\jdk1.5.0\bin




Classpath....This points to the tools.jar file in the jdk directory. It's pretty easy to find. Here is what mine looks like:

.;%classpath%.;C\Program Files\Java\jdk1.5.0\lib\tools.jar

Your's will look similar, although you do not need the .;%classpath%.; statement.


Next, you need to know how to access your files at the command line.

To do so, you simply type cd/folderName at the command line. The cd stands for current directory. My folder was named javawork, so to access it, I did this at the command prompt:

cd/javawork // brings me to the right directory
javac Hello.java //compiles my program
java Hello //runs my program


Let me know if you don't undestand something or need more help.

My path is: c:\matlab\bin;c:\bin;C:\Program Files\ESTsoft\ALZip\;C:\Program Files\Java\jdk1.5.0\bin
& the classpath is:"C:\Program files\java\jdk1.5.0\lib\tools.jar"

Dont be a party pooper!

Anyways, try adding a period to the end of the classpath:

C:\Program files\java\jdk1.5.0\lib\tools.jar.

Get it. Got it. Good.

You should have let me know that it still wasn't working. These problems can take a while to fix.

Now, if you tried putting the period at the end of the .jar extension(.jar.) and it didn't work, try adding this at the VERY beginninng:

.;%classpath%.;

Hi Manisha i am also new to this site you have to set u r classpath.
for eg if you have saved u r program as C:\abc\ then set path to this folder as set path=C:\j2sdk1.4.1\bin; and set calsspath=;.; then u r program will work.
