i not getting why thr bytechunk.java giving error.

it highly appreciated if can throw light on this. thanks.

the problem in handing httpservletrequest in server side using hapi provided api maximum size of buffer in hapi classes capped 4kb.in case hl7 message having base 64 string payload of 20-30 kb. problem solved when incoming httpservletrequest handled in separate dopost method , hl7 message created incoming data.
