Eclipse - Javadoc

Hello,

Apologies for such a basic question.

I already had Eclipse installed and decided against downloading the SDK. After following the setup guide here I noticed the javadocs won’t show.

I tried setting the project properties -> Javadoc Location and even validating the location which was confirmed as correct. It also opens in the web browser just fine but I don’t get any docs on the auto completion or javadoc tab.

Anyone know what I am doing wrong?

Thanks.
