Running Geronimo 3.0.1 under Java 8

[Paul Vorbach]

Hello folks!

I am trying to migrate an existing Geronimo instance from 2.2 to 3.0.1. The
new instance needs to run under Java 8, though.

Trying to run Geronimo (no modifications have been made yet), I get the
following output:

C:\geronimo_filialglt\bin>geronimo run
Using GERONIMO_HOME: C:\geronimo_filialglt
Using GERONIMO_SERVER: C:\geronimo_filialglt
Using GERONIMO_TMPDIR: C:\geronimo_filialglt\var\temp
Using JRE_HOME: C:\Program Files\Java\jdk1.8.0_31\jre
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option
MaxPermSize=128m; support was removed in 8.0
Main not found

I read this has to do with the JVM/JDK. Has anybody else had similar issues
with Java 8 and solved them?

Best regards,
Paul

I found a solution for my problem:

You can rename the property "jre-1.7" in etc/config.properties to
"jre-1.8". After that, Geronimo will start successfully with Java 8.

Paul
