Hi all,

I tried to run this command but faced with the unsupportedclassversionerror. Currently, I am using jdk1.7.0_79. Any advise for me?

C:\windup-distribution-3.0.0.Alpha1>bin\windup.bat --source eap:5 --target eap:7

--input C:\AFService.war

Using Windup at C:\windup-distribution-3.0.0.Alpha1\bin\..

Using Java at C:\Program Files\Java\jdk1.7.0_79\

Hi Wendy,

Windup 3.x switched to JAVA 8, so you need to install Java 8 to use it.
