What should you do?
- Download and install a community-supported MQSeries adapter.
- Use the built-in MQSeries adapter.
- Use the MQSeries application programming interface (API) to write your own MQSeries adapter.
- Download and install the Microsoft-supported MQSeries adapter.
Well this one is kinda obvious, Use the built-in MQSeries adapter.
"For BizTalk Server 2004 the MQSeries adapter was available as a Web
download. In BizTalk Server 2006, the MQSeries support comes built-in. With the
MQSeries adapter, organizations can use XML-enabled MQSeries investments, making it possible to more securely and reliably integrate disparate applications."
