I’m working my way through the Lift Application Development Cookbook by Gilberto T. Garcia Jr and have run up against a problem I can’t seem to resolve. I’ve copied the source code Chap06-map-table and I’m trying to modify it to work with my IBM i (iSeries, AS/400, i5) database. I was able to make it work with the first type of connection using Squeryl Record. However, I can’t seem to figure how to get this to work using a JNDI Datasource. I’ve spent a couple of days searching the internet for examples of setting this up and have not found a good example involving a DB/400 database connection. Below is the error I get when I attempt to start the container and the code I’ve modified in an effort to make it work. Any help would be appreciated. There seems to be some choices for the data source class from jt4oo.jar (jtOpen) and I’m not sure which would be the best to use or perhaps there’s another. I’ve been trying this with each of the three and am assuming the first is the correct one.
