I have a spring MVC application where current oracle version of my application is 1.1.0.7.0 and I have this dependency

<dependency>
    <groupId>com.oracle</groupId>
    <artifactId>ons</artifactId>
    <version>11.1.0.7.0</version>
</dependency>

I need to upgrade to oracle 19c.When I looked at Maven Repository, I found that the Oracle ons artifact is moved to com.oracle.database.jdbc. When I replaced the ons dependency with the new dependency as below, I am getting java.lang.NoClassDefFoundError: oracle/ons/ONS" Errors . Below is my new dependency for oracle 19c. Pease advise.

<dependency>
    <groupId>com.oracle.database.jdbc</groupId>
    <artifactId>ojdbc8</artifactId>
    <version>19.12.0.0</version>
</dependency>
maven oracle spring java

As you already noticed, the artifact has been moved, together with other artifacts.

In particular, to add the ONS library to your project, you need to add this dependency:

<dependency>
   <groupId>com.oracle.database.ha</groupId>
   <artifactId>ons</artifactId>
</dependency>

Here you can find the complete documentation about how to use the new artifacts.
