Attach a cateogry to document using JAVA API's 1

[Adilp]

Dear Friends,

First of all i am very new to Livelink Application.

I am trying to attach a category to the document using java API's. I created a document object and an category object but i can not find any methods to attach a category to the document.
any help is appreciated.

Secondly can someone please tell me if there are any good livelink books for programmers in market. i tried to look on net but i could not find any.

Thank you in Advance ,

Adi.

the best source for livelink api is opentext knowledge base where you will meet a lot of experienced livelink programmers.I say livelink because the API expects you to know the idiosyncracies of livelink to a good extent.Some other resources are

http://www.greggriffiths.org

most of the LAPI samples there were written by me.I try to be as informative in my coding as I can.The yahoo group livelinkteam@yahoo.com can be a good source also.Greg is planning a book.Here's a simple code for Adding Document With Category,If you prefer the source file itself plese drop me a mail at appnair at gmail dot com.This code is for
educational purposes only all the stuff is hardcoded.In production you may want to read the documentation itself.
