Error checking if entity exists
Hi all,
I trying to use CMP EJB with JBOSS 3.2.3 and MS SQL Server 2000.
When I am trying to create a simple EJB I have the following error:
2004-06-09 15:44:25,613 ERROR [org.jboss.ejb.plugins.cmp.jdbc.JDBCCreateEntityCommand.Customer] Error checking if entity exists
java.sql.SQLException: Unexpected token: in statement [SELECT COUNT(*) FROM CUSTOMER WHERE ]

I looked for this error over Internet and this forum, and I didn t found any solution. I m also using Xdoclet with Maven
