developing IDS or honeypot using java

hi,i'm interested to develop either IDS or honeypot using java. i never heard of any java IDS or honeypot API, so it seems I have to start from the scratch, right? Can anyone here show me where should I start?

there is one tool "JHONEYPOT" which is made using java and in case of IDS ,u can just study about snort IDS and find source code of it or logic of snort ,i think it will be simple to implement logic in java.
