java - IceSSL NullPointerException (java)

Question

我正在使用 ICE 中间件开发应用程序。我对 IceSSL 有疑问。像这样配置客户端和服务器之后:

Ice.Plugin.IceSSL=IceSSL.PluginFactory
IceSSL.DefaultDir=.
IceSSL.Keystore=ssl/s/s.jks
IceSSL.Password=qwerty
IceSSL.Truststore=ssl/s/s.jks

我收到这样的错误:

 -- 23.05.12 10:57:55:913 ServerApplication: Network: accepting ssl connection
   local address = 127.0.0.1:10001
   remote address = 127.0.0.1:65415
!! 23.05.12 10:57:56:086 ServerApplication: error: Ice.ThreadPool.Server-0: exception in `Ice.ThreadPool.Server':

   event handler: local address = 127.0.0.1:10001
   remote address = 127.0.0.1:65415

有人知道如何解决这个问题吗？

Answer 1

错误地将证书添加到 keystore 后，我遇到了同样的问题。如果您查看 keytool -list -keystore yourkeystore.jsk 的输出，您将看到证书列表。在我的例子中，两者都被列为 trustedCertEntry(这就是 keytool 在没有私钥的情况下显示证书的方式)。

Enter keystore password:  

(...)
Your keystore contains 2 entries

cacert, May 23, 2012, trustedCertEntry, 
Certificate fingerprint (SHA1): 47:...:5C
rsakey, May 23, 2012, trustedCertEntry, 
Certificate fingerprint (SHA1): D2:...:61

您的证书可能应该列为 PrivateKeyEntry，CA 的列为 trustedCertEntry。

您可以尝试仅使用 key 工具生成证书。它适用于我的情况。希望对您有所帮助。
