Allow updated JDBC Drivers

Current Situation

• The JOC Cockpit includes a number of JDBC Drivers that ship with the product.
• If a users adds an individual JDBC Driver then there is no control of the priority of .jar files with the classpath in Jetty

Desired Behavior

• When specifying during setup that no internal connector should be used then the JOC Cockpit setup should not install the respective internal connectors.

Maintainer Note

• Internal JDBC drivers provided by the setup are no longer included in the war file (./jetty_base/webapps/joc.war), but are stored under ./jetty_base/lib/ext/joc.
• Only those JDBC drivers that are required are stored.

Workaround

• You can apply the attached patch file for use with Oracle databases:
  • stop JOC Cockpit
  • Download patch_20200210_Oracle.zip
  • copy it to the directory ./jetty_base/patches/ of the JOC installation
  • call java jar ./jetty_base/patches/bin/patch-executor<version>.jar
  • start JOC Cockpit
