[xwiki-users] HTTP status 500 - xwiki entreprise 7.1.2 on RHEL6/MySql

Hello, After a lot of tests on a debian version (where « everything » is made for us), i would like to implement the 7.1.2 of wiki enterprise to a dev environment following my company actual "standard ». I hope, after some time and tests, push this into production. The base system is composed by : - RHEL 6.7 - MySQL - Tomcat6 - openjdk 7 I have followed the installation guide to configure everything as i think it must be. But at first launch of xwiki, i have obtained an « HTTP STATUS 500 » with the wall of text below. This is the adapted part ot he hibernate.cfg.xml file related to MySQL if needed : <!-- MySQL configuration. Uncomment if you want to use MySQL and comment out other database configurations. Notes: - if you want the main wiki database to be different than "xwiki" you will also have to set the property xwiki.db in xwiki.cfg file --> <property name="connection.url">jdbc:mysql://localhost/xwiki</property> <property name="connection.username">xwiki</property> <property name="connection.password">xwiki</property> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> <property name="connection.useUnicode">true</property> <property name="connection.characterEncoding">UTF-8</property> <property name="dbcp.poolPreparedStatements">true</property> <property name="dbcp.maxOpenPreparedStatements">20</property> <mapping resource="xwiki.hbm.xml"/> <mapping resource="feeds.hbm.xml"/> <mapping resource="activitystream.hbm.xml"/> <mapping resource="instance.hbm.xml"/> <mapping resource="mailsender.hbm.xml"/> I have first tested the "7.2-Milestone 2 » version. I have seen some error like this one with other people and the milestone 3, with apparently correction to their errors, is not already available as a war file. So I have switched back to the the stable version. Same error… Could you please point me to the right direction with this ? Thanks Daniel. *type* Exception report *message* *description* *The server encountered an internal error () that prevented it from fulfilling this request.* *exception* javax.servlet.ServletException:
