Business Services Server creation - issue

Hi All,
I am trying to create a business services server for our JDE.

I have successfully built full package containing business services, I have created a server in my WLS domain but when I try to create a managed instance using my Server Manager I get:

Unable to install the instance 'BSSV02'; an exception was thrown during the installation procedure. : Exception invoking method install : Exception invoking method configureHttpPort : Failed to connect to WebLogic. Make sure the domain administration server is running.
Failure during invoke:invoke(, , installInstance) javax.management.MBeanException : Unable to install the instance 'BSSV02'; an exception was thrown during the installation procedure.
