Description
Currently, it is possible to define Datasource and Drivers as such in the standalone.xml:
<subsystem xmlns="urn:jboss:domain:datasources:4.0"> <datasources> <datasource jndi-name="java:jboss/datasources/ExampleDS" pool-name="ExampleDS" enabled="true" use-java-context="true"> <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE</connection-url> <driver>h2</driver> <security> <user-name>sa</user-name> <password>sa</password> </security> </datasource> <drivers> <driver name="h2" module="com.h2database.h2"> <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class> </driver> </drivers> </datasources> </subsystem>
The driver module attribute allows to point to a well define module which is fine. Though it doesn't seems possible to point to another "slot" to be able to switch between multiple version of the same driver.
It would be nice if we could do so, ex:
<driver name="h2" module="com.h2database.h2" module-slot="1.0"> <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class> </driver>
Also, while playing with the configuration, I've noticed that whatever you put onto the driver definition will be safely discarded instead of throwing an XSD validation exception. I'm not sure this is the proper behavior as it could be very misleading, ex:
<driver name="h2" module="com.h2database.h2" module-slot="1.0">
Currenly doesn't throw any exception and is getting rewrited to:
<driver name="h2" module="com.h2database.h2">
Should a bug be opened for that? To me it looks a bit similar to: WFLY-4464
The only workaround I'm aware of is to either:
1. create a new main module.xml that depends on the actual versioned slot
2. have the versioning scheme part of the dependency (ex: com/h2database-1.0/main)
Both solutions are not very elegant.
Thanks,
