How to deplay a JDBC Driver that can be used by WepApp
Hello,
we are currently migrating from Tomcat to Wildfly 10 server. We like to take advantages of a Java EE Server. Currently we have some issues with the DataSource. We have deployed the JDBC Driver on Wildfly and set up the DataSource.
That works mainly good, but we like to use DatabaseQueryNotification (Oracle).
Now the problem I run into:
When I package the Driver with my war (additionally), I get an ClassCastException because of mismatch of T4Connection and OracleConnection. Therefore I removed the JDBC-Driver from my War (maven -> scope: provided). But now my Application failed on Deployment, because of NoClassDefFound (see Stacktrace bellow).
How can I make sure that the JDBC Driver can be found by the application?
Thanks in advance!
public class DBListener implements IDBListener, Runnable, DatabaseChangeListener, IPropertyListener, Serializable {
@Resource(lookup = "java:/PlsDS")
private DataSource dataSource;
...
Connection tmpCon = dataSource.getConnection();
connection = (OracleConnection) tmpCon.getMetaData().getConnection();
}
