Vaadin JAR includes the sources and Eclipse parses the JavaDoc directly from there. You shouldn’t need to install the JavaDocs. Just hit
F2 on a method or class and it displays it.
However, some classes and methods do not have JavaDoc at all, in which case Eclipse complains about missing sources or JavaDocs. But the compliet applies only to the particular element.
You can attach external JavaDoc to a package in Eclipse from the project settings. Project Properties → Java Build Path → Web App Libraries → vaadin-x.x.x.jar → JavaDoc location → edit. However, I don’t see that it has any effect, probably as Eclipse already gets the information from the sources.
I have already known the F2 method But unfortunately it is not enough for me
what I would like is to view the online api documentation of vaadin in eclipse
If you press F2 on vaadin component you get a window, with a few buttons at the bottom, and there is one which says “Open external javadoc” unfortunately this button is inactive now
I would like to use that button, so that I dont have to search manually the online javadoc at vaadin.com, just push that button which opens the related documentation at vaadin.com
Ah, I hadn’t noticed the “Open External JavaDoc” button before. It seems to work just ok, once you attach the JavaDoc from Vaadin installation package to the Vaadin Jar. It opens the JavaDoc at the correct position in your default browser. See the instructions in my previous post.
Here’s how you set the JavaDoc path in the project settings:
