My first exercise was to see if I could get Galaxy to work with MySQL. That was very straightforward and worked with no hiccups.
My next exercise was to see if I could configure Galaxy to work with Microsoft SQL Server 2005.
It appears that I've encountered something unusual - and so submitted two potential bug reports to the Mule Galaxy development team:
GALAXY-422: Using Microsoft SQL Server JDBC Driver 2.0 (sqljdbc4.jar) will throw java.lang.UnsupportedClassVersionError: Bad version number in .class file
GALAXY-423: Using Microsoft SQL Server 2005 JDBC Driver 1.2 (sqljdbc.jar) will throw java.lang.NumberFormatException: multiple points at sun.misc.FloatingDecimal.readJavaFormatString
I'll update this posting as my research continues...
