getting method description [message #324085]

Hi,

I would like to be able to see a method's description by simply hovering the
mouse over it. I know this is possible in eclipse since I've seen it
before, I just can't get it with the current version I am using (3.2.2).

Currently what I am seeing is this whenever I hover the mouse over any
element:

Note: This element neither has attached source nor attached Javadoc and
hence no information could be found.

Thanks in advance,

This tells exactly why it's not working: the element you hover over is
probably in a library (jar) which neither has attached source nor Javadoc.

Thank you for your response Daniel.

However, I get this message even when I hover over the keyword 'String', for
example, which is in the Java default library. When I type the . (dot)
after, say, an instance of a String, eclipse displays all the methods for
that String instance..such as trim(), equals(),..etc. However, how do I get
the descriptions of these methods. More precisely, how do I import the
javadoc for these methods so that eclipse can show the description of these
methods.

thanks again,

actually never mind..i solved my problem.

and for those caring to know:

- download the Javadoc for your JDK and unzip it anywhere. This will create
a docs folder for you.
- go to your project properties and select "Java Build Path" and select the
"Libraries" tab.
- expand the "JRE System Library ... " item and select under it the
"rt.jar - C:\blah..blah.."
- you will see two items under it,
- source attachment: (None)
- Javadoc location: (None)
- select "Javadoc localtion" and click on "Edit" on the right.
- then browse to your "docs" forlder that you unzipped before, if the
"package-list" file does not fall directly under the "docs" folder, then it
is most likely under the "api" folder under "docs".
- select whichever folder has the "package-list" file directly under it and
"ok" everything...and bam, you will start seeing descriptions for your
methods.

enjoy and thanks for those who tried to help.

Are you sure you are using a JDK rather than a JRE?
