when i deploy a entity bean, i encounter a error like this:
2004-05-17 08:41:35,810 WARN [org.jboss.system.ServiceController] Problem starting service jboss.j2ee:jndiName=City,service=EJB
org.jboss.deployment.DeploymentException: Error in jbosscmp-jdbc.xml : datasource-mapping MYSQL not found
at org.jboss.ejb.plugins.cmp.jdbc.metadata.JDBCEntityMetaData.(JDBCEntityMetaData.java:374)
at org.jboss.ejb.plugins.cmp.jdbc.metadata.JDBCApplicationMetaData.(JDBCApplicationMetaData.java:237)
...
in standardjbosscmp-jdbc.xml i defined
java:/MYSQLDS
<datasource-mapping>MYSQL</datasource-mapping>
and in standardjaws.xml i defined
java:/MySqlDS
<type-mapping>mySql</type-mapping>
did i do anything wrong? what might cause such an error?
