Hello All,
I am using IBM Websphere MQ classes for .Net and trying to send a message from .Net to MQ using SSL.
1) I have installed MQ Client on my windows 2000 machine and used IBM Key Management Tool to create a key database file (kdb).
2) Created a self-signed certificate in the above created kdb.
3) Extracted the certificate and sent to MQ group to import on their end.
4) Received a certificate from MQ group and I added it to my .kdb.
5) Installed both the certificates on my windows 2000 machine
6) Stash the password for .kdb.
Then, I have the following in my VB .Net code.
'set the MQEnvironment values
qEnvironment.Hostname = hostName
qEnvironment.Port = port
qEnvironment.Channel = channel
'************************************************************
' FOR SSL
'************************************************************
qEnvironment.SSLCipherSpec = "RC4_SHA_US"
qEnvironment.SSLKeyRepository = "F:\installs\keys\rssmq" 'rssmq.kdb is stored in F:\installs\keys
qEnvironment.SSLPeerName = "CN=TRMGR, OU=IT, O=KP"
'************************************************************
'Create a connection to the queue manager using the connection properties just defined
Try
qMgr = New MQQueueManager(qManager)
System.Console.WriteLine("create of MQQueueManager successful")
Catch mqe As IBM.WMQ.MQException
System.Console.WriteLine("create of MQQueueManager ended with {0}", mqe.Message)
End Try
Then , I get the following error:
MQRC_SSL_INITIALIZATION_ERROR
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
I read that SSLPeerName is an optional one. So, I tried without SSLPeerName and got below exception.
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object.
at IBM.WMQ.MQClient.MQCONNX(String qMgrName, MQCNO& mqcno, Int32& pHconn, Int32& pCompCode, Int32& pReason)
at IBM.WMQ.MQClientConnector.MQCONNX(String qMgrName, MQConnectOptions& cno, Int32& hConn, Int32& compCode, Int32& reason)
at IBM.WMQ.MQQueueManager.Connect(String queueManagerName)
at IBM.WMQ.MQQueueManager..ctor(String queueManagerName)
Am I missing anything ? Can anyone please help me ? |

That connection method doesn't support SSL. Check the Clients & Security manuals.

I read that SSL is supported with unmanaged client connections.
How do I speicify "unmanaged client connection" to MQ from my .Net 1.1 code ? Please guide me. Thanks in advance. |

Eh?
There's no indication here that something has been done to set whether this is a managed connection or not.
Also, the error has nothing to do with the type of connection. "Object reference not set to an instance of an object" is purely a .NET programing level error... Perhaps it would be good to know that the right variables are properly initialized. |

How pray did you initialize the MQEnvironment class ?
Your code shows qEnvironment but does not show how this is related to MQEnvironment!

If I use,
Dim qEnvironment As MQEnvironment '* MQEnvironment instance
qEnvironment = New MQEnvironment
I get error,
'IBM.WMQ.MQEnvironment.Private Sub New() is not accessible in this context because it is Private'.
I think this is not causing my original 'object refernce' error. I have used the same code without SSL for MQEnvironment variable and it works perfectly.
It could be something related to SSL installaion. How do I verify SSL intallation is correct on my end ?
I have my self-signed certificate and certtificate signed by MQ Server in my "trusted root certification authorities". I am using windows 2000 with .net 1.1 ? Is there a way to check my SSL intallation is correct ? any ideas ? |

same question - is the MQEnvironment a static class? Do you need to init it?
I have got the same error, but it is stange, as the SSL key repository can be set in the environment variable, if I set it that way, then it is 2059, if set up as MQEnvironment.SSLKeyRepository = @"C:\SSLCertificates\key"; then init error ... no idea how to go around
BTW the ssl cipher value which I use is NULL_SHA |

Yes I believe MQEnvironment is a static class.
Have fun

More precisely, MQEnvironment is a class with static properties.
An application does not need to instantiate MQEnvironment, to get/set its properties. |
