使用Java（1.6.0_17）從mac（10.6.6）發送電子郵件

Question

我正在嘗試從Java程序發送電子郵件。 當我使用Java的早期版本（在我的10.5 Mac上）時，它起作用了，但是由於我得到了10.6.6，所以無法從我的應用程序發送電子郵件。 我得到的錯誤是

Answer 1

可以這樣：

Caused by: java.security.UnrecoverableKeyException: Password must not be null

是你的問題嗎？ 如果沒有，我將在更新后檢查您是否具有正確的SSL庫。

編輯：假設您使用的是openSSL，則應該使用“ openssl version ”。 還要檢查您的“ JAVA_HOME” /“ JRE_HOME ”以及其他此類Java環境變量的設置是否正確，並且可能遵循此人的解決方案來解決類似的問題。 我暗中懷疑您的問題有關。
