Tiny Java utility for reading data from AS/400 database, convert it to JSON, and import it to CouchDB database.
It is NOT a generic tool. You will need to edit the code to use it.
I am sharing it because it was very hard for me to find working code and good documentation for this task.
With time I will improve it and add documentation for others to use.
It is an Eclipse Java project, so the easiest way is to import it in Eclipse. Since it is also a Maven project, I also recommend installing m2e plugin.
You can build an executable jar package with Maven:
mvn package
But first you should manually install jt400 with something like:
mvn install:install-file \
-Dfile=lib/jt400.jar \
-DgroupId=it.nuccioservizi.jars \
-DartifactId=jt400 \
-Dversion=1 -Dpackaging=jar
I put a script in `bin/install-jt400_jar' for convenience. This is because public maven packages are quite old.
You must create a local.properties file with your local settings (usernames, passwords, ...). Or pass them via command line.
Run it as a console Java application.
It all started by the need to build a CouchApp backed by some data available on a legacy as400 system.
Java was chosen for driver support. The open-source jt400 drivers are the best I have found to query an as400 DB. They deal perfectly with character encodings (as400 does not use UTF-8) and they work seamlessly on any platform.
Documentation was the real problem (how to make it work through an SSH tunnel?). So I have decided to share this code hoping it will be useful to others.
