Re: [naviserver-devel] Running TCLWS on NaviServer

[Wolfgang W. <wol...@di...>]

Hi Claudio!

I can confirm what Gustaf wrote below. We are using our own 
initialization routine, which is similar to the one provided by the 
tclws package. We have our own logging facilities, wo we don't need the 
log package:

namespace eval ::WS::AOLserver {
   if {![info exists wsVersion]} {
     variable wsVersion [package require WS::Server]
   }
   #if {![info exists logVersion]} {
   # variable logVersion [package require log]
   #}
}

For returning values, we use exactly the line from Gustaf:

set data(query) [ns_getcontent -as_file false -binary false]

This is handy for REST interfaces as well.

regards,

Wolfgang
