driver-datasource-class-name and driver-xa-datasource-class-name need to be validated when updating --------------------------------------------------------------------------------------------------- Key: WFLY-10640 URL: https://issues.jboss.org/browse/WFLY-10640 Project: WildFly Issue Type: Bug Components: JCA Reporter: Lin Gao Assignee: Lin Gao Priority: Minor Download oracle jdbc driver at http://www.oracle.com/technetwork/database/features/jdbc/jdbc-ucp-122-311... Install the driver as a module and add the JDBC driver: {code:bash} module add --name=com.oracle.jdbc --resources=/opt/Downloads/ojdbc8.jar --dependencies=[javax.api, javax.transaction.api] /subsystem=datasources/jdbc-driver=oracle:add(driver-name=oracle, driver-module-name=com.oracle.jdbc, driver-datasource-class-name=oracle.jdbc.datasource.OracleDataSource, driver-xa-datasource-class-name=oracle.jdbc.xa.client.OracleXADataSource, driver-class-name=oracle.jdbc.OracleDriver) {code} It should fail because the configuraiton: {code:java} driver-datasource-class-name=oracle.jdbc.datasource.OracleDataSource {code} is wrong, +oracle.jdbc.datasource.OracleDataSource+ is an interface, not a concrete class. It should be the same for the data-source creation when specifying the datasource-class.
