Osgi 将JavaMail 1.5与XPages一起使用
我有一个XPage应用程序，可以通过IMAP（和SSL）读取来自GMail的邮件，并将它们存储在nsf数据库中 为此，我需要JavaMail 1.5 在阅读了一些帖子后，我得出结论，我必须构建自己的OSGI插件。 继John Dalsgaard关于的博客之后，我能够将JavaMail 1.5 jar文件包装到OSGI插件中。该插件导出所有JavaMail包，以便我可以在XPage应用程序中使用它们 在我的XPage中，有一些java代码试图建立到GMail的连接。但是连接总是超时，所以我打开了javamail的调试选项。调试表明我的java代码仍然使用javamail 1.3（domino服务器提供的版本） 因此，我将java代码移到了OSGI插件中，并导出了该包，这样我仍然可以在XPage中使用它。打开debug for javamail显示了正确的版本1.5。但是现在我得到了异常Osgi 将JavaMail 1.5与XPages一起使用,osgi,xpages,jakarta-mail,Osgi,Xpages,Jakarta Mail,我有一个XPage应用程序，可以通过IMAP（和SSL）读取来自GMail的邮件，并将它们存储在nsf数据库中 为此，我需要JavaMail 1.5 在阅读了一些帖子后，我得出结论，我必须构建自己的OSGI插件。 继John Dalsgaard关于的博客之后，我能够将JavaMail 1.5 jar文件包装到OSGI插件中。该插件导出所有JavaMail包，以便我可以在XPage应用程序中使用它们 在我的XPage中，有一些java代码试图建立到GMail的连接。但是连接总是超时，所以我打开了j
javax.mail.NoSuchProviderExceptionimapimaps我错过了什么？为什么我不能在osgi插件中使用javamail 1.5 jar文件？我在maven central中找到了这个jar：
它似乎是一个有效的OSGi包。也许这会有所帮助？javax.mail的代码并不真正对OSGi友好。它使用线程上下文类加载器查找实例化实现 您可以通过以下方式对此进行欺骗：
- 将javax.mail和com.sun.mail.imap安装到OSGi容器中。版本1.5.2具有OSGi清单头，因此应该可以工作
- 调用javax.mail api中加载提供程序的函数时，请将线程上下文类加载器设置为肯定知道imap类的类加载器
com.sun.mail.handlers.multipart_mixed incompatible with javax.activation.DataContentHandler
- 删除javax.activation包。这可能会解决问题，因为在这种情况下，每个捆绑包都会连接到系统包。但是，您仍然可以在以后获取ClassNotFoundExceptions。。。与类加载器错误实践作斗争：）
- 从系统包中删除javax.activation。在这种情况下，每个人都将连接到捆绑包。然而，同样的问题也可能发生，javax.activation bundle（或TCC）无法看到应该加载的类
- 在stacktrace中找到一个可以更改TCC的点，并设置一个可以查看所有必需类的类加载器。这也是单核技术的常见技巧（如在原始示例中，但现在用于此函数调用）
- 找到一种具有这些特性但对OSGi更友好的技术。如果你能找到，请把它贴在这里：）
