B4J Question Downgrade application to java 7

[schimanski]

Is it possible to downgrade my application to run under java 7? It runs fine under java 8, but in our company, there is only java 7 on all windows-pc installed.

#AdditionalJar: sqlite-jdbc-3.7.2
#AdditionalJar: bcprov-jdk15on-154

I'm using the follwing librariers:

Most probably no. UI applications depend on Java 8u40+.

You might be able to run it on Java 7 if you don't use fx.Msgbox and the other dialog methods.

Thank you for your fast answer!

I have two more question about it:

1 With the B4J Packager it is easy to install alle necessary java components on the devices. Does the packager renew the existing java 7 components or does it install the java 8 components parallel?

2 Does the java 8 components, which are installed with the packager, ask the system for updates, when there are available? Because it is a closed system, it is better not to stir java-updates.

Thank you for your efforts...

1. It will package the Java version you use when you run B4J Packager.

2.

Does the java 8 components, which are installed with the packager, ask the system for updates, when there are available?

No. They are never being updated.
