Compiling and running using external jar files

I am able to compile the program SendEmail.java, but I can't figure out why isn't it running. Here is the program: 

C:\6sem>javac -cp "C:\Program Files (x86)\Java\jre7\javamail-1.4.7\mail.jar;C:\Program Files (x86)\Java\jre7\javamail-1.4.7\activation.jar" SendEmail.java

C:\6sem>java -cp "C:\Program Files (x86)\Java\jre7\javamail-1.4.7\mail.jar;C:\Program Files (x86)\Java\jre7\javamail-1.4.7\activation.jar" SendEmail

Error: Could not find or load main class SendEmail

Kindly help on how to fix this error.

It happens because of the classPath issue.

Probably SendMail exists in two or more places, but in different Packages

Try this:-

java -cp "C:\Program Files (x86)\Java\jre7\javamail-1.4.7\mail.jar;C:\Program Files (x86)\Java\jre7\javamail-1.4.7\activation.jar" your.actual.class.is.here.SendEmail

You need to specifiy the full name of the class with the package name. This looks like the following example:

java -cp "C:\Program Files (x86)\Java\jre7\javamail-1.4.7\mail.jar;C:\Program Files (x86)\Java\jre7\javamail-1.4.7\activation.jar" com.company.dummy.SendEmail
