Question

好吧，这让我感到困惑。我想用邮件运行jetty maven插件。我被限制在6.1.15，因为我们使用的是JDK 1.6。

我继续得到这个例外。

org.springframework.beans.factory.BeanCreationException: Error creating bean with nam 'mailService' defined in ServletContext resource [/WEB-INF/spring-agenttools.xml]:

Instantiation of bean failed; nested exception is  org.springframework.beans.BeanInstantiationException: Could not instantiate bean class  [com.tttt.iss.agenttools.util.MailService]: Constructor threw exception; nested exception is  

java.lang.ClassCastException: javax.mail.Session cannot be cast to javax.mail.Session

我已经像这样配置了这个插件。如果我从类路径中删除所有mail.jar，我的代码将无法正常工作。如果我添加它，我会得到异常

我怎样才能使这个工作？我使用的是javax.mail：mail：1.4。与Jetty版本相同。

是否可以排除或覆盖Jetty插件邮件？

注意，mail.jar只添加一次到类路径。

更新

当我完全删除mail.jar时，应用程序启动，但我收到以下问题。所以现在我只有一个mail.Session而不是其余的。

感谢您的帮助， Coenos

我使用以下属性

修复了它

<configuration>
   <systemProperties>
     <systemProperty>
        <key>org.mortbay.jetty.webapp.parentLoaderPriority</key>
        <value>true</value>
