OSM deployment with failed osmwebui

Hi everyone,
I've just installed an OSM server:

Specs:
Oracle Enterprise Linux 6u1 (x86-64)
Oracle Database 11gR2
Weblogic 10.3.1.0
OSM 7.0.2

Everything seems to work just fine (cartridge management, oms console), except osmwebui, which gives a "Error 500: Internal Server Error" message:

Error 500--Internal Server Error
