Active-Record JDBC Driver

Dear all,

I am evaluating the usage of Active-Record JDBC, but I received this
error:

RuntimeError in SurveysController#new

The driver encountered an error: cannot load Java class
net.sourceforge.jtds.jdbc.Driver

RAILS_ROOT: D:/workspace/project/teaser

Where do I install the respected Jdbc driver to make it work?

Thanks in advance

What’s your database back end? You’ll need that adapter installed.

So if you’re using Postgres you would need the
activerecord-jdbcpostgresql-adapter gem installed.

Then in your database config you would simply use “jdbcpostgresql” as
your adapter name.

Good luck

You can also put the JDBC driver in your rail’s lib folder. You can also
put it in Jruby’s lib folder. Either one should allow jruby to find it.

If you put it in your application, you’ll need to “require
‘jdbc-driver-name.jar’” inside your application to get it loaded. Your
other option is to put the path to it in the CLASSPATH environment
variable before you start JRuby.
