Creation of individual Java classes within UDFs in mappings?

Hello,

is it possible to create new specific Java classes and objects within UDFs in a mapping?

I often have to do mappings from IDoc (e.g. ORDERS) to some totally different Inhouse structures. I have to work a lot with java in order to map the source structure to the target structure.

It would be easyier if I could define classes like "CAR" and create objects like "myCar1", store them in the globalContainer and read these objects at another position of the target structure.

Is something like that possible?

Thanks,

Christoph
