7:06 p.m.
I'm trying to insert a row into simple table using ejb/jboss but keep getting this
error and stuck for 2 days.
Executing SQL: SELECT COUNT(*) FROM testing WHERE
2009-07-18 19:06:49,718 ERROR
[org.jboss.ejb.plugins.cmp.jdbc.JDBCCreateEntityCommand.TestEJB] Error checking if entity
exists
java.sql.SQLException: You have an error in your SQL syntax; check the manual that

line 1
jbosscmp-jdbc.xml
<enterprise-beans>
<ejb-name>TestEJB</ejb-name>
<table-name>testing</table-name>
<cmp-field>
<field-name>id</field-name>
<column-name>id</column-name>
</cmp-field>
<cmp-field>
<field-name>email</field-name>
<column-name>email</column-name>
</cmp-field>
<!--<entity-command name="mysql-get-generated-keys"/>-->
</enterprise-beans>
table 'testing' just has two fields viz. id and email. id being primary and
auto-increment. (Though it's an auto-increment but I'm passing id value as well)
Following is the complete error. Not sure what I'm doing right. Any help would be
greatly appreciated
