Hi Ron,
Thanks for the reply.
Below are some more code samples from my stalled project.
If I remove ICompanyDao's 'GetByID' method, (and it's corresponding call in
the CompanyService ), leaving ICompanyDao devoid of any members, everything
seems to work!
The moment I include a method in the ICompanyDao I get the "Error
configuring DAO. Cause: Ambiguous match found" error.
Any input appreciated.
Many thanks
Jason

Subject: Re: Error configuring DAO. Cause: Ambiguous match found.
Can we see ICompanyDao and the method signatures from the class that
implements ICompanyDao. This looks like a DynamicProxy exception.
