java.lang.NoClassDefFoundError: oracle/jdbc/pool/OracleDataSource - New One

Question

I have Standalone application which has been migrated from Oracle 11g to 12c.I have changed the jar file from ojdbc14.jar to ojdbc7.jar (JVM version is 7).In Code also i have changed the oracle.jdbc.driverType.OracleTypes to oracle.jdbc.OracleTypes also oracle.jdbc.pool.OracleDataSource is mapping to Ojdbc7.jar.its working in local but its failing DEV Env with above exception. PS:-All the neccesary dependency also kept in lib folder and ojdbc14.jar has been replaced with ojdbc7.jar in DEV ENV,but still its throwing the above exception. Any Suggestions?

Answer 1

This must be a classpath issue. This class oracle.jdbc.pool.OracleDataSource is in ojdbc7.jar. You can check your classpath by looking at how java is launched in the DEV environment (the classpath is often set in the command line).

Answer 2

Aside from checking it is in the classpath, make sure that the file permissions for directory and jar file is properly set so that your application can access it.
