According to the mySQL reference:

http://dev.mysql.com/doc/mysql/en/Legal_names.html

It is possible to create tables and columns with reserved
names by using the backquote character: `.

Using JBoss 4.0.0, JDK 1.5 and mySQL 4.0.21 (the latest
production version) results in a SQL exception from
using the following in jbosscmp-jdbc.xml :

<entity>
<ejb-name>Session</ejb-name>
<table-name>`SESSION`</table-name>
<cmp-field>
<field-name>id</field-name>
<column-name>ID</column-name>
....

However, when the backquotes are used for column
names - NO EXCEPTION occurs.

If I try and issue the SQL commands manually with the
backquotes this works fine.

It would appear the generated SQL is incorrect when
reserved words for table names are backquoted.

Below is the exception when trying to create the table
`SESSION`.
