Modified: periodicity/conf/database/developers databases.xml
Added:
periodicity/src/plugins-build/database/src/java/org/apache/commons/periodicity/database
DriverContentHandler.java
Log:
Changed the representation of driver schemes from
<scheme>jdbc:database</scheme>
<protocol>
<scheme>jdbc:database</scheme>
</protocol>
A scheme should no longer be put directly in <driver> element. It must
be nested in a protocol element inside the driver element.
Added a SAX content handler to parse driver information out of the
databases.xml file.
