I use Oracle MapViewer to generate my mapping data and currently I'm using an Oracle database as my spatial back-end. I would like to move my data over the PostGIS but I can't find any references if Oracle MapViewer actually supports PostGIS.

So my question is? Is there out of the box support for PostGIS? Would I have to write my own custom spatial data provider?

MapViewer is specifically built for Oracle Spatial. It not as good as one wishes. Geoserver was a better option in our workplace. –  Mapperz Jan 10 '13 at 22:18
    
@Mapperz Hmmm... not good to hear. Sadly we already have a lot invested in MapViewer. –  Mark Robinson Jan 11 '13 at 0:19

There is no support for PostGIS in Oracle MapViewer, AFAIK.

MapViewer relies on Oracle Spatial, their SDO_GEOMETRY type and Oracle SQL syntax dialect. MDSYS database schema is full of Oracle-specific GIS metadata, custom types etc. which cannot be easily ported to another database engine.
It uses JDBC to connect to database, which could theoretically allow it to connect to a non-Oracle server too, but it's not enough.

I know MapViewer has an alternative spatial provider interface but I think it's more intended for things like Shapefiles to supplement an Oracle installation. I ended up going with GeoServer. –  Mark Robinson Jan 23 '13 at 16:33
