I've installed NHaystack 1.2.5 on a Niagara 3.5 system. Through the station I can query points just fine. tHowever when I try o post an HTTP request to <server>/haystack, the platform application director gives:
ERROR [10:35:49 15-Dec-15 PST][web] Internal Server Error
java.lang.NullPointerException

Am I missing any steps on the installation process for NHaystack?

What happens if you do /haystack/ops or /haystack/about? There could be a problem with redirects not working with /haystack.

/haystack/ops gives
ver:"2.0"
name,summary
"about","Summary information for server"
"ops","Operations supported by this server"
"formats","Grid data formats supported by this server"
"read","Read entity records in database"
"nav","Navigate record tree"
"watchSub","Watch subscription"
"watchUnsub","Watch unsubscription"
"watchPoll","Watch poll cov or refresh"
"pointWrite","Read/write writable point priority array"
"hisRead","Read time series from historian"
"hisWrite","Write time series data to historian"
"invokeAction","Invoke action on target entity"
"extendedRead","Extended Read"
"extended","Extended Functions"
I think you are fine then. This is probably some kind of bug with redirect handling in the servlet -- I'll look into it. It should be pretty benign though.

/haystack/ops gives
and /haystack/about gives
productName,moduleName,productVersion,serverTime,tz,moduleUri,serverName,productUri,serverBootTime,haystackVersion,moduleVersion "Niagara AX","nhaystack","3.5.25.1",2015-12-15T11:24:22.460-08:00 Los_Angeles,"Los_Angeles",`https://bitbucket.org/jasondbriggs/nhaystack`,"Leavitt_MS",`http://www.tridium.com/`,2015-12-15T10:32:48.056-08:00 Los_Angeles,"2.0","1.2.5"
So that seems to be working ok.
