[Gvsig_english] Problems using geoBD with Oracle layer

To know the spatial indexes of a table you can execute that SQL:
 
SELECT INDEX_NAME,STATUS
FROM USER_INDEXES 
WHERE TABLE_NAME='MYTABLE' AND ITYP_NAME='SPATIAL_INDEX'
ORDER BY INDEX_NAME
 
By the way, there is a known bug related with spatial indexes reported some days ago. The next release of the extension will have it resolved. Sorry for the inconvenience...
 
And about ogr2ogr... the log is showing that the SRID (the Oracle specific code with the coordinate system and datum information) is null. I've experienced some problems with the new JCRS extension and the Oracle driver, and it seems that is related with that situation (a layer/table without reference information). We will work on it.
 
Thank you for your comments.

Hello Jorge,
thanks for your comment. I browsed through the gvSIG-logfile, and found that the layers seem to have this information, like

"DEBUG AWT-EventQueue-1 es.prodevelop.cit.gvsig.fmap.drivers.jdbc.oracle.OracleSpatialDriver - ======================================================

Ok. What I do not know yet is whether this layer has a spatial index or not. I'll try to find out this.


Additionally, I added a table to this database on my own using ogr2ogr. The geometry column of this layer is detected by gvSIG. However this layer cannot be added to my view - 

The layer in the log:
DEBUG AWT-EventQueue-1 es.prodevelop.cit.gvsig.fmap.drivers.jdbc.oracle.OracleSpatialDriver - OWNER: RGBUSER1

and the error message:

I just don't really get it. Ideas?
