Two question about KM API

Hi all,

I have a requirement to use KM API, to upload doc files to a specific repo & to display a list for user download files.

Now I get two problem:

1, how to write description while creating a resource.

I know how to create resource, but after new a Content, I tried to new instance of IMutableProperty and write in, there's ReadOnlyPropertyExcetion, I do not know where to set property of this resource.

2, I did above test by setting sharing reference in webdynpro reference & import some external jar files, this works fine for standalone component. But if I want to checkIn it as a DC to NWDI, I got compile error, what kind of used DC shall I import, I guess this is the way DC can accept.

Thank you

William
