Canu00B4t see log with J2EE Visual Admin or Standalone Log Viewer

Question

Bom dia!
When logging on Log Viewer, it shows de error message: Unable to invoke LogControllerFacadeMBean method:"getMetaDataOfReaders" In J2EE Visual Admin the error message after click in the item Log Viewer is Error while loading service Log Viewer
When I click in defaultTrace.trc nothing appears. The same for the others log archives listed in Log Viewer.
Can someone help me with this?
Very thanks from Spain.
In the console I see the following java exception:
Exception in thread "AWT-EventQueue-0" com.sapmarkets.bam.util.BAMRuntimeExcepti
on: Unable to invoke LogControllerFacadeMBean method: "getMetaDataOfReaders".

Hello Ivan,
Make sure that you are using a supported JDK version as per note below:
723909 Java VM settings for J2EE 6.40/7.0
And also, make sure that the necessary environment variables are pointing to the correct JDK version.
Regards,
Rafael
