samples of SAP Trex catalog

Hi,

iam looking for Java TREX samples to access the catalog. unable to find these anywhere in SAP world.

any samples using the

"com.sapmarkets.isa.catalog.trex"

or

"com.sapportals.trex.core" packages.

i need ways to access the Catalog in ISA which has been configured to Trex.

any help would be greatly appreciated.
