I need to create a standalone Swing application with an embedded database
that can be downloaded to 500 workstation using Java Web Start. I have the
following questions:
1.- Can I use Derby downloading it using Java Web Start?
Yes, just include the derby JAR file in your JNLP file:
<resources>
<j2se version="1.5+" java-vm-args="-Xms8m -Xmx32m"
href="http://java.sun.com/products/autodl/j2se"/>
<jar href="<MyApp.jar"/>
<jar href="derby.jar"/>
</resources>
2.- What happens when I download a new version of Deby? Will it upgrade my
database files automatically without ANY user intervention?
