Configuring JDBC agent in BAM workbench

Hi,

I am triying to define a new event in BAM application workbench.
I am getting the following error even I use the predefined JDBC
agent "adobe_jdbc_agent" in BAM workbench.The error detail is below.

Could anyone tell me what is wrong and how can I fix it?

Thanks

Cihan
