Question

我创建了一个自定义SSLSocketFactory类并将其设置如下

ldapEnv.put(Context.SECURITY_PROTOCOL, "ssl");
ldapEnv.put(FACTORY_SOCKET, socketFactoryClass);

LdapContext ldapContext = new InitialLdapContext(ldapEnv, null);

从Eclipse Dev Environment运行并从命令提示符运行它作为Jar文件时，它工作正常。但是当我将它包装在服务包装器中并将其作为Windows服务启动时，它不起作用。我得到以下异常，

javax.naming.CommunicationException: 192.168.100.22:636 [Root exception is java.lang.ClassNotFoundException: com/testing/diraccess/service/ActiveDirectory$TestSSLFactory]

任何帮助???

似乎这个问题可能是由于JNDI依赖于设置正确的线程上下文类加载器（管理员可能没有这样做），这是必需的，因为JNDI类是由加载器层次结构和类加载器的类加载器加载的。将找不到应用程序/容器类加载器加载的类。所以JNDI提供了一个钩子来通过线程上下文类加载器来加载这些类。

看看是否有效，

 // Save the current thread context class loader
 ClassLoader currentCL = Thread.currentThread().getContextClassLoader();

// Set the context class loader to the one we know for sure loaded classes inside configstore-core.jar
Thread.currentThread().setContextClassLoader(OmParticipant.class.getClassLoader());

// Invoke the jndi related code that will internally try to load our socket factory impl
...

//restore the original class loader
Thread.currentThread().setContextClassLoader(currentCL );

我发布此问题已经很长时间了。由于这篇文章没有任何答案，似乎也得到了一些观点，我想我可以分享我最后解决的问题（我已经在几年前的问题评论部分发布了这个）。

我能够通过使用-Xbootclasspath/a:选项将该jar文件包含在引导加载程序类路径中来解决此问题。但无论如何我不喜欢这个解决方案。
