I am trying to compile the simple c++ code which publish the message using fastrtpsgen command. For example, fastrtpsgen HelloWorld.idl

This is output:

Afaik, if you're not using the ROS 2 message generation infrastructure, you'll have to follow the regular setup and installation instructions for FastRTPS. Those include installing a JDK if I remember correctly.

This is not really a ROS related issue though and this forum is trying to focus on ROS Q&A only.

It might be better to ask the FastRTPS maintainers this question.
