Hello everyone.
First of all, sorry if this post not be on the correct site of forum, I am new here.
I have used Eclipse since 2014 as the default IDE for Java programming, and recently decided to uninstall Eclipse Neon and move to the latest version of Eclipse. But in the new version, when I write a method and the intellisense screen appears that offers different possible methods, the second screen that offered API information of the method suggested by intellisense, does not appear.
Throughout the last 7 days I have been looking for a solution on the Internet, but I did not see anyone with the same problem, so I am a little strange.
On the other hand, I have checked the program settings, but I did not find the option to activate the screen, partly because I do not know the name of it either.
It is strange that the new version does not allow users to use an option, which in Neon was by default and I see it so useful, but I want to know if it is possible to activate it in the settings, and if so, how can I do it.
Does anyone know?
My question is simple: How can I activate the second intellisense screen that shows Java API information about suggested methods in the intellisense screen in Eclipse?
This is the screen that I can't see in the latest version:
(I attach a picture to show the screen)
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
My Eclipse is:
Version: 2020-09 (4.17.0)
Build id: 20200910-1200
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Those are actually modules and packages for supporting the generation of Javadoc, not actual reference Javadoc. It looks like you'll need to 1) Install an actual JDK from somewhere like adoptopenjdk.net , 2) add the newly installed JDK to your Installed JREs preference page, and 3) right-click on that node and choose that JDK instead of the the current value, which looks like the one provided to run Eclipse itself.
In general, if you're going to develop something using Java, you should install and use a full JDK and not just a Java runtime.

True, but note that the jars are all in the .p2 pool. Is this JRE14 the justj JRE bundled with Eclipse so that Eclipse can run at all without users having to install a JRE/JDK first?
Perhaps the EPPs for Java should include not a JRE but a JDK, and the Oomph installer should set up a JDK when it installs an Eclipse for Java development?
Or perhaps things should be set up such that the justj JREs used to run Eclipse are not available as Java targets to build against? If a JDK cannot be included for whatever reason, an Eclipse for Java development could even prompt the user to download and install a JDK if none can be found. Even better, it could do it for the user: show a dialog, let the user select the Java version(s), download and install the JDK(s).
(There are also some other reports about people not being able to run javac. Likely that's also related to them having only a (justj?) JRE but no JDK.)
@Ed Merks, what's your take on this?

I have been trying different options and I have tried to install Eclipse on another computer and I have the same problem, so I have thought that maybe it is that I installed the wrong java, the jdk, the jre and the eclipse itself ... It is something that surprises me , but, it's the only thing I can think of doing at this point.
Do you have this information screen in your Eclipse next to the Intellisense screen?
Do you know if there is any way to completely uninstall Eclipse, Java, JDK and JRE, to be able to do an installation from scratch and in the correct order through a complete guide that certifies that the program is perfectly installed and functional?
It is to leave doubts.
I ask, because if the failure occurs on two different computers, I think it is unlikely that it is a failure of the computer itself. Although I am almost completely convinced that this window has to be enabled or disabled in Eclipse. But in the absence of finding an option that allows you to do so, if you have this window simply by installing the program, I understand that it may be a configuration error in the installation.
I honestly don't know what else to do or try.
