Hi ,
I don't know if this is the right place to post my question because it relates to JAVA . I am beginner of JAVA , using a tutorial as reference I am trying to run a simple program in JAVA env. I have installed JDSK kit from java.sun.com but when I tried to run a program from the DOS prompt , I am getting this error ,
This what I typed in : C:/Documents and Setting\javac -classpath ExampleProgram.java
Error I got :
'javac' is not recognized as an internal or external command.


I tried to set the environment variable also, but it is not working.

Please help.

Thanks.

What env variables have you set ?

JAVA_HOME/bin directory should be in your path. JAVA_HOME is where you
have installed the java sdk.

Also, if you set the env variables, you need to open another command prompt window and then try your command, again.

Thanks Vino.

I have installed jdk in c:/Program Files directory. Won't I be able to use from this location.
If you don't mind could u walk me through the steps after installation .


thanks

If c:\Program Files\j2sdk1.5 is where you have installed java sdk.

You can run javac from this directory as well. But getting a command prompt to traverse to this directory requires you to type in extra. So put c:\Program Files\j2sdk1.5\bin in your path. After that you can run javac, java from anywhere.

It is best that you set classpath to include the current directory. Just append a . to the CLASSPATH settings if not already set.

javac ExampleProgram.java

Look at this instruction manual

Hi Vino,
Thanks for your time.

But still I am getting error saying "cannot read:ExampleProgram.java"

These are all the steps I tried .

1. I made C:/Program Files\Java\jdk1.5.0_04\bin (this were I have installed jdk) as my current working directory.
2 . then I setted up my CLASSPATH -->
C:/Program Files\Java\jdk1.5.0_04\bin > SET CLASSPATH=%CLASSPATH%;.

3. then I complied my program from the above location :

C:/Program Files\Java\jdk1.5.0_04\bin >javac ExampleProgram.java
At this stage I am getting this error .
error : "cannot read:ExampleProgram.java" 1 error

Here is what the code I wrote :
class ExampleProgram {
public static void main(String[] args){
System.out.println("I'm a Simple Program");
}
}

Could you tell me what I am missing here? I appreciate your patience and time vino.


Thanks.

Where did you place the ExampleProgram.java? Right inside jdkXXXXX\bin?? You shouldn't put any user programs inside!

I will start again.

You should add the following to your path variables.
C:/Program Files/Java/jdk1.5.0_04/bin

You will need the classpath setting SET CLASSPATH=%CLASSPATH%;.

Suppose, all your java programs are placed in c:/ANAMIKA56

You will need to traverse to c:/ANAMIKA56 and then issue javac ExampleProgram.java

Once the program is compiled, run it as follows: java ExampleProgram

The path settings is necessary because after that, you go to any directory you want and then issue a javac/java. If you dont set the path variable, you need to do the following everytime. C:/Program Files/Java/jdk1.5.0_04/bin/javac ExampleProgram.java.

Like cbkihong said, its good not to put any java programs inside the java installation directory.
