Spatial Data in EJB with JBOSS

Question

Hello,
how do I handle Entity Beans with spatial fields (type sdo_geometry)to JBoss?
I have problems to insert data this way: I get
an SQL-Exception "Invalid column type"
I think the problem is the jdbc-datatype mapping in JBoss (jbosscmp-jdbc). No matter which jdbc-type I use, the exception occurs anyway.

Hi Syedurur,
You may be in the wrong forum as OBIEE only utilizes MapViewer as far as I know.

So as Stefan notes, you are not going to be able to use SDE.ST_GEOMETRY with OBIEE as its not an Oracle product.  However, your ArcSDE registered MDSYS.SDO_GEOMETRY geometry should work fine.  Yet in your example you posted you seem to have Web Mercator (3857) ordinates but the SDO_SRID is WGS 84 (8307) so that is mangled and not going to draw anything correctly.  Try changing the SDO_SRID to 3857.
Now Stefan is a bit incorrect about the ease of moving from SDE.ST_GEOMETRY to MDSYS.SDO_GEOMETRY.  The folks at ESRI make it simple to move in the other direction but - surprise! - not to move away from their proprietary spatial type. 
ArcGIS Help (10.2, 10.2.1, and 10.2.2)
Now you can still accomplish this by exporting your data from the geodatabase and then importing it back in as SDO but that is certainly not as simple as using the above one-step migration tool.
In theory you could convert SDE.ST_GEOMETRY to MDSYS.SDO_GEOMETRY on the fly in the database with SQL.  Both ESRI and Oracle proudly spout their unwavering support for OGC standards.  Thus this should work
SELECT MDSYS.SDO_GEOMETRY(SDE.ST_AsText(a.shape),8307) FROM my_ESRI_ST_GEO_table a;
(Note change the 8307 to the matching Oracle SRID of your data)
But my experience was that the very old Oracle Java WKT parser mixed with the somewhat non-standard ESRI External DLL WKT writer is not a very reliable combination.  But do give it a try and feel free to report back to us how it goes.  I really have not tried this in a couple of years so perhaps things are better now.
Cheers and Happy New Years,
