NetBeans third party javadoc adding problem

Question

I'm trying to add zxing java doc. I've tried different approaches:
1) Java Platforms > Javadoc, rather than Tools > Libraries > Javadoc
2) * Go to Project Properties > Libraries dialog
* On "Compile" tab press the "Add JAR/Folder" button and locate your library
* On "Compile" tab press the "Edit" button with your library selected
* Add javadoc path

I tried different paths:
a) "javadoc" folder, containing index.html
b) "docs" folder, containing "javadocs" folder
c) zip file, containing "docs" folder

But neither of that helped me - I always receive "Javadoc not found. Either Javadoc documentation for this item does not exist or you have not added specified Javadoc in the Java Platform Manager or the Library Manager."

Answer 1

To add a javadoc of a third party library first you have to create a library bundle inside Netbeans. Go to Library Manager (Tools > Libraries) window and create a New Library. You will have to add necessary jar files manually under Library Classpath tab.

Then switch to Javadoc tab and give the path to your javadoc zip file. Click OK and Netbeans will display the documentation straight away.
