Sith Pleadings 
Which connector(JDBC, ODBC) geopointe is used to access the salesforce data. Is there any open source JDBC Connectors is available to connect salesforce data?.
Mohamed, note that we at SpatialKey do not access the Salesforce data directly. The Geopointe application (which runs on the Salesforce platform) accesses the data and moves it to SpatialKey.
With that said, there is no JBDC or ODBC connection being made in Geopointe. It is a native Salesforce APEX application and uses Salesforce APIs to get at the data. For more information you would need to contact the Geopointe folks. I personally am not a Salesforce expert.
