Colin, thanks for your suggestions.  Sorry it has taken me so long to get
back to this.  This is, indeed, a local connection, though the application
is designed to run on multiple platforms, so I don't want to introduce too
much iSeries-specific stuff.

I can get this to work, as I can the jdbc:db2://localhost form of the URL,
and indeed, the version I'm accustomed which specifies the name of the SQL
collection (= library) on the URL, like this:
jdbc:db2://localhost/library-name.

All well and good.  However, it seems to me that I ought to be able to do
the same thing when using the toolbox driver with native optimisations.  So
using a URL like jdbc:as400://localhost/library-name, after loading
com.ibm.as400.access.AS400JDBCDriver, should work.  However, instead I get
an SQLException saying "Password is *NONE" (see stack trace below).

Now, we can tell our clients that they should use the native driver; but I
think that both drivers ought to behave in the same way here, and that the
native driver is doing the correct thing.  Others may disagree, of course.
I would be particularly interested to hear from the Toolbox developers who
sometimes post here; or anyone who has any ideas about how to get round
this, of course.

Note also that I get the same results when I call
DriverManager.getConnection(url) as when I call
DriverManager.getConnection(url, user, password) with null values for user
and password, or with "*CURRENT" for user and password.

Here's the stack trace when I use the Toolbox driver with native
optimisations:
