JavaMail库上的限制错误

Question

When trying to use the Session class from the javamail library I get an error:

Description Resource Path Location Type Access restriction: The type Session is not accessible due to restriction on required library C:\\Program Files\\Java\\jre7\\lib\\ext\\mail.jar Mailer.java /MailerApp/src line 21 Java Problem

Don't I have the library in the right place? I have the folder in the jdf1.7.0_01/jre/lib/ext directory.

您无需将库放在jre/lib/ext ，只需以常规方式将其添加到应用程序的类路径中（您无需说出所使用的IDE或构建系统，因此我无济于事“通常的方式”将是）。
