[Geoserver-devel] problems with postgis-datasource

[Jean-Pierre P. <jp...@dp...>]

hello!

i just installed geoserver 0.98 as a webapplication in tomcat 4.1.24 (jsdk 
1.4.2) on win xp. the example in the "topp--road"-directory with the 
shapefile works perfectly. to get some experience i tried to modify the 
example so that it works with postgis. i applied shp2sql to road.shp and 
loaded the data in a table called 'road''. i didn't change the schema.xml 
but modified the info.xml:

<?xml version="1.0" encoding="UTF-8"?>
<featureType xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
         <Name>road</Name>
         <Title>Random Road Centerlines</Title>
         <Abstract>This is some random road features</Abstract>
         <Keywords>road, New York City, TOPP</Keywords>
         <SRS>-1</SRS>
         <LatLonBoundingBox minx="-74.27000" miny="40.50000" 
maxx="-73.80000" maxy="40.94000"/>
         <Host>localhost</Host>
         <Port>5432</Port>
         <DatabaseName>test</DatabaseName>
         <User>Jean-Pierre</User>
         <Password/>
         <Dbtype>postgis</Dbtype>
         <Table>road</Table>
</featureType>

now i receive the following exception when i execute a request ( 
http://127.0.0.1:8081/geoserver/Dispatcher?request=GetFeature&typename=road ):

with LoggingLevel on FINEST i can see, that all connection-parameters from 
info.xml a read correctly.

do you have an idea what i could do to avoid this exception?

thanks
