How to import Business Publisher Objects into a JSP

Hi

I am trying to import Objects of business publisher to my jsp, but i can´t figured it out the full address.

for example:

com.idsscheer.aris.businesspublisher.application.business.common.environment.IBPEnvironment

I want to import the IBPSearchContext Object, can someone help me to find the full path?

i have a second question, i have a custom jsp inside the business publisher that have a list of models (IBPModelContext) is there a way to get the modelId from that object.

Thank you for your time

See ya
