"); With only this class and ojdbc7.jar in the current directory, run the following tests: Try loading class oracle.jdbc.OracleDriver >java -XX:-UseSplitVerifier -cp ojdbc7.jar;. The exception means that it cannot find that file on the classpath or in any of the jars on the classpath.

C:\>java -version java version "1.8.0_281" Since this class is not a wrapper, just check to see if this implements the requested interface. For example, if the property value is set to 10, Connection Labeling reuses high-cost connections when there are no low-cost connections available and the total connections reach 10. If a Universal Connection Pool instance is not yet created, this method must first create a pool instance, in which case pool and connection factory configuration properties should be set on this adapter prior to invoking this method.
