server.xml:
<GlobalNamingResources>
<Resource name="jdbc/mydatasource"
auth="Container"
type="javax.sql.DataSource"
maxActive="16"
maxIdle="8"
maxWait="10000"
username="abc"
password="xyz"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost/mydatabase?autoReconnect=true"
/>
</GlobalNamingResources>
As I said, if I move the META-INF/context.xml contents
into my server.xml, then it works fine, but then I
cannot use ant manager tasks to redeploy.
I have also tried to put the driver jar into the
application war. No luck.
