javax.mail.NoSuchProviderException:在使用Free8.5.5.9和Apache 1.4时

Question

我有一个发送邮件的网络应用程序。为了执行邮件发送，我使用了基于1.4的库。当我使用Websphere fine 8.5.5.7时，一切都很好，但是在升级到8.5.5.9之后，它停止工作并抛出一个异常：javax.mail.NoSuchProviderException --完整堆栈跟踪--我在问题末尾发布的。

同样，我尝试在Websphere fine 8.5.5.7和8.5.5.9的两个安装上运行它，在第一个安装上，它在第二个坏掉时运行得很好。我试着看看两者之间的区别，它看起来自由本身就有com.ibm.ws.javax.mail-1.5_1.5.xx.jar包，它会干扰commons-email 1.4使用的Java javax-mail-1.5.2，在这里看它的pom.xml。

经过一些调试，我注意到：解放8.5.5.9使用com.ibm.ws.javax.mail-1.5_1.5.12.jar，而解放8.5.5.7使用com.ibm.ws.javax.mail-1.5_1.5.10.jar可能--这是对我的错误造成的。

因此，我的问题是，我如何消除com.ibm.ws.javax.mail的影响，它与自由一起使它发挥作用，或者还有其他解决办法？另外，我可以在哪里为自由小组提交错误报告？

Update：它看起来自由有可以启用或禁用的JavaMail 1.5特性，我没有显式地启用它，它看起来在我的特性中隐式地启用了它，这是我的特性列表：

<featureManager>
        <feature>jdbc-4.1</feature>
        <feature>adminCenter-1.0</feature>
        <feature>jndi-1.0</feature>
        <feature>localConnector-1.0</feature>
        <feature>servlet-3.1</feature>
        <feature>ssl-1.0</feature>
        <feature>jaxrs-2.0</feature>
        <feature>cdi-1.2</feature>
        <feature>ejbLite-3.2</feature>
        <feature>jsf-2.2</feature>
    </featureManager>

更新2我通过使用本文：用替代版本覆盖提供的API解决了这个问题

只需在server.xml中进行以下更改：

<application id="" name="Scholar" type="ear" location="scholar.ear">
  <classloader delegation="parentLast" />
</application>

现在你的图书馆将获得比自由图书馆更高的优先权。

Answer 2

从Free8.5.5.8到8.5.5.9更新后，我点击了javax.mail.NoSuchProviderException: smtp。将<feature>javaMail-1.5</feature>添加到我的server.xml中为我工作。
