Hello,
please refer to this TechNote:

(prereq Eclipse version for the RTC Client is 3.3.2)

As you intend to use the J2EE Eclipse, also be aware of:
https://jazz.net/jazz/web/projects/Rational%20Team%20Concert#action=com.ibm.team.workitem.viewWorkItem&id=63965

workaround: after unzipping the Eclipse J2EE packages, be sure to start
Eclipse a first time before installing RTC CLient)

For building J2EE applications, i need to use the existing eclipse
with J2EE.

I have tried to search for options for using exisiting eclipse while
installing rtc express client but couldn't find.
