2.自己用的

myeclipse中發送郵件出現Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/mail/util/LineInputStream

出現這個問題的原因是jar包版本不統一,解決方案如下:
我在項目匯入了jar包

與myeclipse內建jar衝突了

刪除Java EE 5 Libraries/javaee.jar/mail裡的包有東西.

具體操作：

進入myeclipse的安裝目錄：我安裝的是myeclipse blue 8.5 具體路徑如下

E:\development_tools\myeclipse_8.5\install_d\common\plugins\com.genuitec.eclipse.j2eedt.core_8.5.0.me201003231033\data\libraryset\EE_5

找到javaee.jar，開啟後刪除mail檔案夾即可（需要先關閉運行著的myeclipse，否則無法刪除）
