Hi Derick -

I believe that what you need can be done by specifying database install 
information on the IJ command line.  This is how I setup my install 
scripts.  If the installation is complex you can wrap the commands in an 
OS script like Bryan suggests or just document the command (gets pretty 
long)  that needs to be typed by the person performing the install.  The 
scripts that IJ reads can only contain IJ commands and standard SQL 
commands, there is no programming API for IJ - Java is the Derby API and 
can do everything IJ can and more.  Here is an example of the IJ command 
line that uses variables to create a DB and specify the install 
information the reads the SQL script 'doDbSetup.sql' and saves the 
output/messages in doDbSetup.log.

 -- variables

-- command line
java -Dij.protocol=jdbc:derby:  
-Dij.database=$INSTALLDIR/$DBNAME$DBOPTIONS org.apache.derby.tools.ij 
<   doDbSetup.sql   >> doDbSetup.log
