Compression

[fe...@gmail.com]

Hi everybody, I'm looking on the internet to find compression classes that 
can be used with java.nio, but I can't find them.

I only want to create an IoFilter that can deflate and inflate data on the 
fly when it arrives, because I have to send many repetition over the same 
connection in my protocol, and java.zip is uneffective in my case ( many 
little repetitive packets).

Has somebody any idea about what I can do?
I have find jzlib but it seems like if it is no more in development.

thanks to all!

https://issues.apache.org/jira/browse/DIRMINA-179

I've attached the patch file.  You will also need jzlib-1.0.7.jar

I dont know if I'm supposed to upload that to jira as well.  You can
make your own jar after downloading the source from here -

You are a god mister 8)
I was already trying to write my own implementation but I started from the 
scratch, so I was lost.

Thanks a lot!

Seems like this is your lucky day.  I've just finished implementing a
compression filter with MINA.  Had sent it to trustin for review
yesterday.  I still have to open a JIRA issue since I've not finished
testing it out.  You're welcome to try it out.  Let me open a JIRA
issue and attach the diff file.
