I'm running the standalone version of Jaspersoft Studio 1.0.7. I was able to connect it to my development JasperServer CE 4.5 server as well as to a Production JS CE 4.2 server. I was able to create a database connector to my SQL Server database. I have NOT been able to test the connector, in fact when I kill and restart the studio because it sits there and does nothing, the two data connectors replicate themselves in the listing but deleting one, deletes both. I have NOT been able to create a new report (SQL Query) as when I go to get the fields from the data connector, I get a "Progress Information" popup with the line "Use initiated job" and nothing happens. I will be reverting back to iReport until Jaspersoft Studio really works. Running Java7, Windows 7 Pro, 64 bit
