Call web service in handleGpioPinDigitalStateChangeEvent? - Raspberry Pi Forums

dear forumers!

i'd call webservice when pir sensor active.
created web service call wsimport:
wsimport -keep -s src http://webservicex.net/geoipservice.asmx?wsdl

wrote test application. in code call service on start, , call again when pir sensor gettig active.
first calling right, when try call on handlegpiopindigitalstatechangeevent method of gpiopinlistenerdigital object i've got nullpointerexception in pi4j-gpio-event-executor-0.

have idea how change code?

thank in advance can provide.

adrian

it looks sequence:

code: select all

geoipservice service = new geoipservice(); service.getgeoipservicesoap(); 

fail if run twice inside same application.

code work once if once inside event handler?
