Thank you for your answer Maxim, I checked the files and found a file called openjpa-2.1.0 in the lib directory. I deleted that file and now it works.
I don’t know where the version comes from, my colleague downloaded it two days ago… (I’ll ask him and check if the file is in that version); Thanks again, All the best, Vital, De : Maxim Solodovnik [mailto:solomax...@gmail.com] Envoyé : mardi 6 mai 2014 13:17 À : Openmeetings user-list Objet : Re: OM 3.0 Loading room freeze Your logs are really weird Especially this part: java.lang.RuntimeException: public static volatile javax.persistence.metamodel.SingularAttribute org.apache.openmeetings.db.entity.basic.MailMessage_.ics at org.apache.openjpa.persistence.meta.MetamodelImpl.populate(MetamodelImpl.java:330) ~[openjpa-2.1.0.jar:2.1.0] Om 3.0.1 is bundled with OpnJPA 2.2.2 How you get this version?

Everything went fine, no problem during installation, all the tools are also installed. I can log into OM but when I try to enter a room (a default one) I see the blue loading bar and when the bar is full, it just stops. Can’t enter any room, it just freeze when loading. I don’t know where the problem could be. I’ve attached OM log, there is an error but I don’t understand it. Thank you for your help. All the best, Vital, -- WBR Maxim aka solomax
