Urgent! Problem connecting C# & JAVA with EAServer 5.5

[Imran]

Dear All,

I need to connect my C# project with EASERVER 5.5. I want to use some
of the components deployed on easerver. The components deployed on
easerver are PB NVO's.

I generated .TLB files for the components. But when i add reference
in
the DotNet it gives me error that TLB is not valid.

"Please make sure the tlb file is valid Com or assembly."

I am not getting how i can connect my C# project with easerver 5.5.

Regards
Imran Zaheer
