OpenAMF and Tomcat's Http11NioProtocol connector

Hi all,

 

Has anyone every successfully used OpenAMF with Tomcat's
Http11NioProtocol connector before?  I have an installation of my
application where ARP is not going to work and wanted to use the
Http11NioProtocol instead.    

 

The problem is, within OpenAMF I am getting a DataInputStream EOF error
while parsing the headers.  (Note that Http11NioProtocol is non-blocking
on request headers.)  The only three solutions that I can think of are:

  

a)       don't use Http11NioProtocol (which performs better than the
standard connector)

b)       find a way to make Http11NioProtocol request header reads
blocking

c)       find a way to make OpenAMF read  non-blocking headers

 

Your thoughts and experiences would be appreciated.  

 

Cheers,

 

Stu
