Could not list layers for this store, an error occurred retrieving them: Unable to acquire a reader for this coverage with format: ImageMosaicJDBC

hosuresh
Hi...


I followed the steps as in below link
http://docs.geoserver.org/stable/en/user/tutorials/imagemosaic-jdbc/imagemosaic-jdbc_tutorial.html

FWtool version am using is: 2.4.7
Geoserver: 2.1.2

I was got the below option in Store as i was added the plugin in proper directory.

ImageMosaicJDBC - Image mosaicking/pyramidal jdbc plugin

Steps i followed:

gdalinfo C:/working/PLU_rast.tif

gdal_retile -co "WORLDFILE=YES"  -r bilinear -ps 512 512 -of PNG -levels 5 -targetDir C:/working/tile C:/working/PLU_rast.tif

java -jar C:/GeoserverTomcat/webapps/geoserver/WEB-INF/lib/gt-imagemosaic-jdbc-2.7.3.jar

java -jar C:/GeoserverTomcat/webapps/geoserver/WEB-INF/lib/gt-imagemosaic-jdbc-2.7.3.jar ddl -config C:/GeoserverTomcat/webapps/geoserver/data/coverages/osm.postgis.xml -spatialTNPrefix tileosm -pyramids 5 -statementDelim ";" -srs 4326 -targetDir C:/working/sqlscript

java -jar C:/GeoserverTomcat/webapps/geoserver/WEB-INF/lib/gt-imagemosaic-jdbc-2.7.3.jar import -config C:/GeoserverTomcat/webapps/geoserver/data/coverages/osm.postgis.xml -spatialTNPrefix tileosm -tileTNPrefix tileosm -dir C:/working/tile -ext png


All  the above commands are executed properly...
If u find any mistakes in above commands please help me and...

My osm.postgis.xml file is like:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE ImageMosaicJDBCConfig [
  <!ENTITY mapping PUBLIC "mapping"  "mapping.postgis.xml.inc">
  <!ENTITY connect PUBLIC "connect"  "connect.postgis.xml.inc">]>
<config version="1.0">
  <coverageName name="osm"/>
  <coordsys name="EPSG:4326"/>
 
  <scaleop  interpolation="2"/>
  <verify cardinality="false"/>
  &mapping;
  &connect;
</config>



After it need to add the store so...
selected the ImageMosaicJDBC - Image mosaicking/pyramidal jdbc plugin
I given the name to store and
given the url file:coverages/osm.postgis.xml

After it it was taking some time.
store with the name displayed in the Store

After it want to add the layer from store
I selected the Layer... it was loading for some time after it its Displaying error like:

Could not list layers for this store, an error occurred retrieving them: Unable to acquire a reader for this coverage with format: ImageMosaicJDBC


when i check the logs they are like:
