Hi,
I'm a new user of geotools and i'm trying to use de SpearfihPostgis
sample to view data from my own postgis database.
I'm not changing significant parts of the code but i'm getting this error:
java.lang.NullPointerException
at
org.geotools.renderer.j2d.RenderedLayerFactory.findGeometry(RenderedLayerFactory.java:685)
I'm guessing the mapcontext is not getting any data from the database,
but i don't know why.
I'm not familiar with neither PostGIS and RenderedLayerFactory (I didn't wrote this class). But
looking at the source code, it sound like that a Feature contains no data (in which case throwing a
NullPointerException would be a RenderedLayerFactory bug). If you have any chance to step through
the code, it may be worth to put a break point on RenderedLayerFactory line 661 and check what
'geoName' is, and if an attribute exists for this name.
Martin.
