problem with jboss and mysql

[jbjsg]

when i deploy a entity bean, i encounter an 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
< datasource >java:/MYSQLDS < /datasource >
< datasource-mapping >MYSQL< /datasource-mapping>
and in standardjaws.xml i defined
< datasource >java:/MySqlDS< /datasource >
< type-mapping >mySql< /type-mapping >

did i do anything wrong? what might cause such an error?

This is not a JCA issue, you should be in the CMP forum
(or probably more correctly the beginners forum)

I suggest you read the getting started guide, rather than posting every basic error
into the forums.

Here's a hint (notice the case):

[ejort@htimes2 conf]$ grep -ri mysql standardjbosscmp-jdbc.xml
 <name>mySQL</name>
