Caused by: java.lang.NullPointerException

Hi there, this is an AXIS service!
Perhaps there will be a form for invoking the service here...
Using JasperServer 5.2.0 and JasperStudio 5.5.0.

Answer 1

This may likely be due to some local HTTP proxy setup problem.
To solve this you can try the following:
Window->Preferences->General->Network Connections->
Provider: Manual (where Eclipse proxy settings are applied)
(adjust proxy rules as desired) (try including/excluding rules matching your jasper server host)
restart Eclipse (important!)
I found this solution a little hidden here: Jasper forum question 3143 comment 16.
