I am decoding http packets. And I faced a problem that chunk problem. When I get a http packet it has a header and body. When transefer-encoding is chunked I don't know what to do ?

Is there a useful API or class for dechunk the data in JAVA ?

And if someone , experienced about http decoding , please show me a way how to do this ?

Use a fullworthy HTTP client like Apache HttpComponents Client or just the Java SE provided java.net.URLConnection (mini tutorial here). Both handles it fully transparently and gives you a "normal" InputStream back. HttpClient in turn also comes with a ChunkedInputStream which you just have to decorate your InputStream with.

If you really insist in homegrowing a library for this, then I'd suggest to create a class like ChunkedInputStream extends InputStream and write logic accordingly. You can find more detail how to parse it in this Wikipedia article.
