Feed Description: Java related topics for all major areas. So you will see J2ME, J2SE and J2EE issues here.
Until recently, i allways had problems with distributing demo applications to my customers (with demo i mean snapshots of a current software project in the J2SE area), because of the database involved. There was allways the issue with syncronizing the structure and changing the drivers, because normally i am using different databases than my customers. All this was quite time consuming and error prone and it was time to move to a better solution for demoing.
Because of JBoss, i was aware of hsqldb (is hypersonicSQL a deprecated name?) and after googling for alternatives, i only saw cloudscape, but being an IBM product, i thought that hsqldb is most likely faster to deploy and integrate.
All in all, the docs are well organized, so it took me about 10 minutes to integrate a test database into my current Swing Application. The GUI tools to create and maintain the database are simple but sufficient. After correcting some JDO mappings, i was able to run my application with hsqldb.
And when i am speaking of JDO, again it was so nice to see that i only had to edit _one_ jdo vendor config file in order to replace my former DB2v8 target database to hsqldb. Now i can just package my application with the db directory inside and put a 500k hsqldb jar in the classpath. Everything else is just a: java -jar MyApp.jar
