Hello,

Our current release (2.1.0) and earlier don't work with the latest GeoServer (2.14) - there was a large package renaming for JTS, which provides all the geometry implementations. Our next release (2.2.0) will work with GeoServer 2.14, but not earlier versions. So for now, you should use GeoServer 2.12 or 2.13 (2.13 had bugs that affected some GeoMesa functionality, so you may be safer with the latest 2.12).

Thanks,

Emilio

Hi all,

Hoping someone might be able to help:

 

I’m trying to setup geomesa-hbase and Geoserver on Amazon EMR. I have a working HBase and Geomesa install and have successfully imported many millions of points. I now need to put Geoserver on top of this but have run into complications. Having followed the setup guide on geomesa.org for the Geoserver plugin, I am able to add Geomesa as a store. I had to download jts-1.13.jar for this to succeed, and when I go to publish a layer Geoserver can see the data schema. If I try to compute bounds from the data an exception is thrown:

java.lang.ClassCastException: org.locationtech.jts.geom.Envelope cannot be cast to com.vividsolutions.jts.geom.Envelope

 

If I use EPSG native bounds and just add the layer it claims to succeed, but if I try to preview the layer then I get an exception:

java.lang.VerifyError: Bad type on operand stack Exception Details: Location: org/locationtech/geomesa/index/geotools/GeoMesaFeatureCollection.accepts(Lorg/opengis/feature/FeatureVisitor;Lorg/opengis/util/ProgressListener;)V @74: invokevirtual Reason: Type 'org/geotools/geometry/jts/ReferencedEnvelope' (current frame, stack[1]) is not assignable to 'com/vividsolutions/jts/geom/Envelope

 

I clearly have some kind of JAR conflict going on but I’m not sure which side is right! Do I go with LocationTech or Vivid Solutions?

 

As a further aside, I had to include htrace4 to overcome a NoClassDefFoundError relating to htrace where I had only got htrace-3.x installed.

 

Many thanks in advance,

 

Roger
