I have EAR project, that consists of the following projects:
- TestRemoteEJB
- TestRemoteEJBClient
- TestRemoteWEB
Under each project I have set:
- Under Java Compiler I have set Compiler compliance level to 1.7
- Under Project Facets I have set Java to version 1.7
Also each project has JRE system library set to JRE7. If I use this settings, when I publish on JBoss AS7, I get UnsupportedClassVersionError. If I change the previously specified settings to 1.6 and JRE6, it successfully deploys. Why is that it works under 1.6, but not under 1.7 settings? I have the following setup on my computer.
For x86 I have:
- JRE6
- JRE7
For x64 I have:
- JDK 1.7 (which I found out is pointless as Eclipse uses its own compiler)
- JRE7
I am running Eclipse Indigo SR2 x86 edition, as I had some problems with x64 edition.
Make sure JBoss server pointing to correct Java version.
