Hello friends. I'm an experienced Java programmer, but never had used the hibernate, this is my first time with it.
I've got tired of searching solutions for my problem, and with no success. I hope some other can help me fix this problem.

I'm running JDK 5 in eclipse (no plugins), to build a J2SE server, that communicates with a MySQL 5, using InnoDB.

It throws a com.mysql.jdbc.exceptions.MySQLSyntaxErrorException, and says the syntax is incorrect. But the SQL comes as a lot of interrogation points.
Tryed a lot of configurations. Including putting the user and password in commas, but then it tells the username/password is incorrect. The problems is really freaking me out, because I can't read the SQL, and its not telling the real source of the error, just some Warnings and the Exceptions. The warnings and exceptions, due to appear order, are the following:
  • WARNING: Could not obtain connection to query metadata
  • com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '????????????????????????????????' at line 1
  • WARNING: SQL Error: 1064, SQLState: 42000
  • SEVERE: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '????????????????????????????????' at line 1
Hera are all the mapping and configuration XMLs, inside this quoting and code tags.

Problem Solved: Updated Compiler from JDK5 to JDK6... Seems like the MySQL Connector (or something else) was incompactible with JDK5.
