Birt runtime in tomcat jdbc connection error

Question

I created a report in Birt 4.4.0 and now want to view the report in the birt runtime in my tomcat 8.0.26. The report connects to an Oracle database and works fine in the report designer but when I execute it in the birt runtime I get the following exceptions:

I put the jdbc .jar in the tomcat's lib folder and in the WEB-INF/lib folder of the birt runtime. Also, the report uses a connection profile.

Hope someone has an idea.

The issue somehow sorted out in the comments - but for anyone landing on this question:

• you need a jar containing oracle.jdbc.driver.OracleDriver in your Application
• Search for jars containing that class in google and you will probably land at oracle's driver page (11g release or 12c release or similar). ojdbc6.jar or ojdbc7.jar is probably what you are looking for.
• for to check, whether you have a correct jar file: rename the jar file to ".zip", extract it, and find OracleDriver.java in the folder oracle/jdbc/driver/. If it exists, then this jar should help you avoid that ClassNotFound exception
