-------------------------------------
Key: GEOT-1215
URL: http://jira.codehaus.org/browse/GEOT-1215
Project: GeoTools
Issue Type: Bug
Components: data mysql
Affects Versions: 2.4.M1
Reporter: Debasish Sahu
Assigned To: Gary Sheppard
Fix For: 2.4.M2
MySQLDataStore currently does not supports CRS , cause of which when one tries
to render mysql geometries using StreamingRendererer (2.4-M1)
the following exception is thrown

A possible fix is to modify the buildAttributeType to take in account the CRS
of the table or geometry .Example modification of Mulitpolygon
return AttributeTypeFactory.newAttributeType(rs
.getString(COLUMN_NAME), MultiPolygon.class);
to
return
AttributeTypeFactory.newAttributeType(rs.getString(COLUMN_NAME),Geometry.class,
false, 0, null,DefaultGeographicCRS.WGS84);
