How to use API documentation in Eclipse?

If i add some jar to my build path and want to see some hints as i type when programming (e.g. parameters and return values of some functions), how can it be achieved? E.g. 开发者_如何学编程 I want some help when using Axis and online documentation is available (http://ws.apache.org/axis/java/apiDocs/index.html).

How to "import" this or any other similiar javadocs into Eclipse?

Open the Project Preference and go to Java Build Path. There you can attach javadoc location for every jar you have.

1. In the Package Explorer view expand your project and its library folder for the Axis library.

2. Right-click the Axis jar and select Properties.

3. In the Properties dialog, select Javadoc Location in the tree on the left.

4. With the Javadoc URL option selected, click Browse.

5. Navigate to the appropriate folder (see table that follows) and click OK twice to exit the Properties dialog.
