The JavaDoc popup remains empty, how do I install documentation?

Problem: "No javadoc found" in Editor popup window.

Solution: Download and install the "Java SE Documentation" files from sun.com.

Download documentation for your Java platform (either JDK1.5 or JDK6)

• http://java.sun.com/javase/downloads/ - current version (JDK 6)
• http://java.sun.com/javase/downloads/index_jdk5.jsp - JDK 1.5

Save the file; you do not need to unzip it.

1. In NetBeans IDE, go to "Tools > Java Platforms".
2. Select the platform that you use, and click the Javadoc tab.
3. Click "Add ZIP/Folder" and browse to where you save the file, e.g. jdk-6-doc.zip, then click "Add".
4. Close the Java Platform Manager.

The Javadoc popup should now work and display more information on the usage of a command.
