证书签名validation失败

我的网站托管在亚马逊上。 它建立在java 1.4.2_13的微软版本上。 我注意到电子邮件没有出去。 我没有对代码进行任何更改。 我在亚马逊的网站上找到了这个文件，并按照他们的指示找出我们的java环境没有通过测试。 所以，我导入了新的ssl根证书。 我可以validation它是否在密钥库中，但是当我运行其shaTest并且仍然没有发送电子邮件时，我收到以下错误消息。 任何帮助表示赞赏。 谢谢！

Java本身在1.4.2中得到了SHA256支持，但微软Java可能没有 – 特别是因为它已经停止了很长时间。 你也许可以使用bouncycastle 。

注意Java 1.4于2002年问世。 那是14年前的事了。 那应该是一个巨大的红旗; 我不会在连接到互联网的任何机器上运行它。
