Hi Jin,
Can you confirm you installed the driver?
Code:
roo> addon search jtds
1 found, sorted by rank; T = trusted developer; R = Roo 1.1 compatible
ID T R DESCRIPTION -------------------------------------------------------------
01 Y Y 1.2.4.0001 #jdbcdriver driverclass:net.sourceforge.jtds.jdbc.Driver.
This bundle wraps the standard Maven artifact: jtds-1.2.4.
--------------------------------------------------------------------------------
...
roo> addon install id --searchResultId 01
Target resource(s):
-------------------
Spring Roo - Wrapping - jtds (1.2.4.0001)
Deploying...done.
Successfully installed add-on: Spring Roo - Wrapping - jtds [version: 1.2.4.0001]
...
roo> osgi ps
If you issue the 'osgi ps' command, does it list the jdts driver at the end of the list? It should read something like this:
[ 74] [Active ] [ 1] Spring Roo - Wrapping - jtds (1.2.4.0001)
