I'm upgrading some custom java code from our 10.2 environment to a new 10.3 HF3 environment and I'm running into the following error when launching Tomcat 9 under Eclipse 4.16.0:
Caused by: java.lang.NoClassDefFoundError: javax/transaction/SystemException
The target production environment is:
Java EE 1.8
This has been resolved - I rolled-back some of the unneeded Maven dependencies and I can launch Tomcat and render pages now.
