Hi everyone,
I'm pretty new on pentaho Bi-Server and I'm trying to move my first steps into.
I've configured the Server on Ubuntu and I can access the console at pentahoserver:8080
I sucessfully created a datasource, connecting to a MSSQL 2008 database hosted by another machine on the LAN.
When I try to crete a new report I do these steps:
1) Log on Pentaho server
2) Create New Report
3) Add datasource "SQL Query"
Now, if I hit Data Preview I correctly see 10 records from my Table.
If I press "Finish" I have this error:
Unable to generate model: java.lang.UnsupportedClassVersionError: net/sourceforge/jtds/jdbc/Driver : Unsupported major.minor version 51.0 (unable to load class net.sourceforge.jtds.jdbc.Driver)
That's kinda strange because if the problem was the jdbc class, how can I see the data preview?
My catalina.out says:
17:46:09,860 ERROR [DatasourceServiceImpl] DatasourceServiceImpl.ERROR_0011 - Unable to generate model: java.lang.UnsupportedClassVersionError: net/sourceforge/jtds/jdbc/Driver : Unsupported major.minor version 51.0 (unable to load class net.sourceforge.jtds.jdbc.Driver)

etc.
I have both sqljdbc4.jar and jtds-1.3.0.jar in the lib directory (tomcat/lib), but the datasource is defined as jdbc:sqlserver
Any guess?
