Did you try adding the current folder (.) to the classpath?

In addition to GGolf's fine advice, which should solve that immediate problem, let me add a couple of extras:

- http://sscce.org/
This fine discussion of the Simple, Self-Contained Compilable (Correct) Example (SSCCE) by Andrew Thompson will help you two ways. Creating an exampleoften reveals the problem to you before you post your question, and the example isolates your issue and makes it easier for people to respond sensibly. GGolf was clever to figure out your issue without an SSCCE.

- Use packages.
You put 'SendMailTLSDFC' in the default package, or "no-package" package. Don't do that.

Also, study the Java tutorial and other documentation on classpaths.

You need

java -cp . SendMailTLSDFC

Otherwise the java command assumes "." is the name of the class you
are trying to run.

java -cp . SendMailTLSDFC

are trying to run.

Deepak, you should read the documentation on the "javac" and "java" commands.

Randomly tossing strings into your command isn't nearly as effective as
looking up the correct syntax and using it.

java -cp . SendMailTLSDFC

are trying to run.

To the OP: You'll need mail.jar on the classpath too, so the command
will be:

java -cp D:\mail.jar;. SendMailTLSDFC

They forget that the simplest language is the one you

markup language will bit by bit become even more convoluted
and complicated than HTML because of the unplanned way it grows.
