Right. You need to download the source and/or the Javadoc to a local
drive and then change the source and/or Javadoc location of the rt.jar
to that location.

Hi, thanks for replying.
Can you tell me where to change the javadoc location? Is it in properties->javadoc location? I thought it's location to export javadoc?
A person here said that too
| Quote: | In Eclipse 4.5 Galileo, the place you're looking for is probably under the project's Properties -> Javadoc location, but that's for the generated Javadoc.
This is wrong, actually. For 3rd party projects, you need to go to Package Explorer -> References Libraries and access the Properties of the JAR you imported. There, you have a Javadoc Location.
I've just tested this with Apache HttpComponents Client.
|
But I cannot find where's package explorer.
And the last, if netbeans can show the javadoc offline means that I already have javadoc downloaded somewhere? I cannot find any javadoc in netbeans directory..

"Bumping" the forum is useless. We're all eager to answer every question
that comes along, each according to his capacity and knowledge. If your
question hasn't been answered, it simply means no one who knows has read

Let me take a stab at answering this question.
First, I'm not certain which sorts of things you're looking to get hints on.
If it's third party stuff, say a class out of a Hibernate or some such
JAR, there is a way to "hook up" the Javadoc. If this is the case, or
something close to it, please examine
http://www.javahotchocolate.com/tutorials/jars.html, particularly
Appendix D: Setting up a third-party library. This will show you how to
wire up source code or Javadoc so that, from your Eclipse code editor,
you can hover over a symbol to see information or get a hint while
typing in an expression.
I hope this is helpful. If it isn't, it may help you narrow down what
functionality you're looking for.

Hi, I found where to change the setting of javadoc, it really is connecting to internet to get javadoc.
It's not third party stuff, JPanel is already included in Java default SDK right?
Here's the screenshot to make more clear
http://j.imagehost.org/0490/javadoc2.jpg
Sorry, I want to ask more:
1. I have to change the javadoc for every single jar? and for every new project I create? Is there no default setting to change it?
screenshot -> http://a.imagehost.org/0887/javadoc.jpg
2. I tried to download javadoc here
it says that it's already include in java sdk but I cannot find any javadoc in java sdk folder, I only found javadoc.exe.
In netbeans I only found org-netbeans-modules-javadoc.jar, it seems that it's module to generate javadoc but it's working offline in netbeans proofs that the javadoc is already in my computer?
If only javadoc working offline in eclipse, it would be better than netbeans.. 
I'm using Eclipse IDE for Java EE Developers (190 MB), should I download Eclipse IDE for Java and Report Developers (221 MB) to get the javadoc offline?
Thanks

I'm going to punt a little on some of these issues on the off-chance
someone else knows more.
I'm 99.9% certain that different Eclipse downloads will make no
difference in what or how you see Javadoc.
I don't have any trouble getting getting Javadoc for just about anything
I decide I want and I added that section to my tutorial on JARs in
consequence although I do know know just a little bit more now. Perhaps
I'll update it.
I hope someone can see through your impediments better than I.
Best of luck,
Russ

If you are interested in the javadoc for the JDK, then your best bet is
to insure you are using a JDK and not a JRE and to also make sure that
you have installed the source code for the JDK. Eclipse will then
automatically associate the source with the JDK and display both the
source code and javadoc.
JDK source is incuded in a file called src.zip. It is simply a zip file
of the .java files that make up the JDK. Leave the file as (don't unzip
it). It is normally going to be in the base directory of the JDK after
installation.
Since you aren't able to see the javadoc locally, My guess is you never
installed it or you are running against a JRE instead of a JDK. If you
are running against a JRE, I would recommend that you install a JDK and
use that for your development. You can defined the JDK/JRE that Eclipse
uses on the Window->Preferences->Java->Installed JRE section. Use the
Add or Edit buttons to point to a JDK.
If you are pointing to a JDK and still aren't seeing the javadoc
locally, then you need to associate the source with the JDK. ON the
same Installed JRE screen, use the Edit button to edit the settings for
the JDK. In the list of jar files, you can set source attachment.
Select all the jar files (click on first one, shift click on last one)
and select the Source Attachment button. Navigate to the location where
the src.zip file is located and select it.
You can also set a separate Javadoc location in a similar manner by
using the Javadoc location button. However, if the source attachment is
successful, you shouldn't need the javadoc location.
Once set for a workspace, all projects created will use the locations
for the default JDK so they will pick it up automatically.

Yes it's already working!
eclipse is pointing to jre folder instead of jdk.
I have jre6 and jdk1.6.0_16 installed in java folder(I have the jre first then installed jdk later).
Now I also know that the javadoc is in the src.zip folder.
Your instruction is very clear.
Thanks a lot!

The point we've been trying gently to make, Leon, is that it's not best
practice to point Eclipse at a mere JRE. You've expended a great deal of
time and effort on this problem, which you haven't fixed yet, that would
not have arisen if you'd simply downloaded a JDK and pointed Eclipse at
it using eclipse.ini.
Good luck,
Russ
