Hi Christian
I still haven't got this to work. Perhaps I am not creating the
pregeneralized shape files correctly. When I attempt to load a
pregeneralized shape file into a JMapPane I get the following stack trace:
java.lang.ArrayIndexOutOfBoundsException: 4

I am attempting to pregeneralize a standard esri shape file containing roads
(roads50.shp). I based my config file on the example
'geninfo_shapefile.xml' in the
modules\plugin\feature-pregeneralized\src\test\resources directory:
<?xml version="1.0" encoding="UTF-8"?>
<GeneralizationInfos version="1.0">
<GeneralizationInfo dataSourceName="file:target/0/streams.properties"
featureName="GenStreams" baseFeatureName="streams"
geomPropertyName="the_geom">
<Generalization dataSourceName="file:target/5.0/streams.shp"
distance="5"
featureName="streams" geomPropertyName="the_geom"/>
<Generalization dataSourceName="file:target/10.0/streams.shp"
distance="10" featureName="streams" geomPropertyName="the_geom"/>
<Generalization dataSourceName="file:target/20.0/streams.shp"
distance="20" featureName="streams" geomPropertyName="the_geom"/>
<Generalization dataSourceName="file:target/50.0/streams.shp"
distance="50" featureName="streams" geomPropertyName="the_geom"/>
</GeneralizationInfo>
</GeneralizationInfos>
I have a few questions:
- I was unable to locate the 'file:target/0/streams.properties' file, I
image that it contains some database connection properties. I have used a
URI to my original shape file instead, is that OK?
- Can the 'featureName' value (GenStreams) be any name or is it based on
some value within the original shape file?
- Can the 'baseFeatureName' value (streams) be any name or is it based on
some value within the original shape file?
The version of the config file I'm using is shown above in my original post.
Thanks,
Richard
