tc/bl/exception/lib obsolete DC dependencies

Hi,

In my project, I have 2 warnings because I'm using dependencies that are deprecated. They are:

tc/bl/exception/lib

Warning Reason: DC tc/bl/exception/lib is obsolete and should no longer be used. This functionnality is provided by SUN JSDK.

tc/bl/jrfc/api

Warning Reason: The component is deprecated.

What should I do with that? Should I deleted them? How can I replace them with correct dependencies?

Thanks for your help!

Martin
