Send mail first introduce the package path of Java EE to classpath, already installed JBuilder can be found in its installation path Lib directory
To Mail.jar,activation.jar, add the two packages to the system's environment variables, so you can even do so without jbuilder development
was used.

After compiling, create a text file in the directory of class file Mailserver.properties,
Format:
