I'll try to answer, but you'll have to accept that sometimes product names are rather poorly chosen.

JServer: name for the Java VM running inside an Oracle instance, either for an 8i database or 9i database. As far as I know, packages like utl_smtp depend on it.

JServ: old servlet engine by Apache, distributed by Oracle with their 8i database.

OC4J: servlet, JSP and EJB container, originally developed by Ironflare under the Orion name, about 1.5 years ago licensed by Oracle and now developed separately, is the Java core of Oracle's 9i application server.

Tomcat: servlet and JSP (not EJB) container developed by the Jakarta project, you can think of it as an evolution of JServ if you like, but the two are completely different code bases.

You cannot expect to find OC4J in your Oracle 8i database installation, though if you download OC4J from Oracle it can be made to connect to an Oracle 8i database.
