Open Source Java HTTP Codecs

Question

I am writing a web server from the scratch. There I need a Http codec which can decode a string request (buffer) to an Http object and encode http object into Sting (buffer).

I found three Codecs,

1. Apache Codecs (can't use this because this is tightly coupled with their server coding structure)
2. Netty Codes (can't use this because this is tightly coupled with their server coding structure)
3. JDrupes Codecs (Has some concurrency issues)

But non of these can be used for my purpose. Are there any other Codecs I can use?
