Java 1.7.0_03 Error: Could not find or load main class

I just upgraded to the latest Java

> java -version
java version "1.7.0_03"
Java(TM) SE Runtime Environment (build 1.7.0_03-b05)
Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02, mixed mode)
> javac -version
javac 1.7.0_03

I am having issues to execute Java program from the command-line. For instance:

public class Tester {
    public static void main(String[] args) {
        System.out.println("in main");
    }
}

I compiled it on the command-line, then try to execute it:

> javac Tester.java
> java Tester
Error: Could not find or load main class Tester

Is this a bug? Strangely, I have no problem to execute the program using Eclipse.

classpath=.

if you want to run program in current working directory where your class reside.

java gives three options.

first option

java -cp Tester

Second option for current working directory

java -cp . Tester

Third option export CLASSPATH variable

export CLASSPATH=$CLASSPATH:. (this is the best one if your directory changes) or

export CLASSPATH=$PWD

export CLASSPATH=

after that you must sorce the bashrc or bashprofile.

I had the same error when trying to run Tomcat and realized it was because I was using a 64 bit version of Tomcat on a 32 bit system. Once I tried the 32 bit version, it worked.
