ERROR running wallet first time: NoClassDefFoundError

[bulrush15]

I installed the Iota full GUI node from Github. The file I used was IOTA.Wallet.Setup.2.5.4.exe on Windows 8. I also installed JDK 9.0.1, and set up the path to Java in Control panel, and rebooted the PC. I copied the IRI.jar file to the iri directory, and when I start the Iota GUI node I get this error:

12/07 05:07:10.000 [main] INFO com.iota.iri.IRI - 

Welcome to IRI 1.4.1.3Exception in thread "main"java.lang.NoClassDefFoundError: javax/xml/bind/ValidationException  at com.iota.iri.IRI.main(IRI.java:55)  Caused by: java.lang.ClassNotFoundException:

1 more  Process exited with status 1

Any ideas how to fix this? Are there other system variables I'm supposed to set up?

I can't set up any nodes because I get this error.

Thank you. I'm trying to set up a full node to help the community.

Should I install the JRE 8 or JDK 8?
