Java Forum / General / July 2007how to display java API document in eclipse
Hi, I'm new to Eclipse. Is there a way to display java API specification when the mouse is on a standard java class/function? For example, when I hover on the word "System", it should display the spec of java.lang.System like the following page or similar content? http://java.sun.com/javase/6/docs/api/java/lang/System.html I specified javadoc location (http://java.sun.com/j2se/1.5.0/docs/ api/) in project properties in eclipse, but when I hover on the word System, a small yellow popup box displays: "java.lang,System Note: This element neither has attached source nor attached javadoc and hence no information could be found" Did I do anything wrong?

What you have to do, is to specify the Javadoc location of your JRE system library (especially "rt.jar", because this jar file contains the classes java.lang.*, etc). You can do it from the tree view in your package explorer: Right-click on "JRE System Library - rt.jar"; from the pop-up-menu select "Properties"; in the dialog go to "Javadoc location" and enter your location.

(on my system I have "C:/Programme/Java/jdk1.6.0_01/src.zip") Actually it is the "java source attachment" (not the "javadoc loaction") from where eclipse gets the texts showing up in the yellow pop-ups.

But this is not what I want. I am trying to display the following page in eclipse, for example, http://java.sun.com/javase/6/docs/api/java/sql/Connection.html (it'll be better if it is displayed in frame) when I click (or by any other action) on the word "Connection" in my code.

There are two categories of Javadoc as far as Eclipse is concerned: 1) Javadoc you generate for the classes you write yourself. 2) Javadoc for the Sun class libraries You have applied a solution intended for 1 to the docs for 2. > I am trying to display the following page in eclipse, for example, > http://java.sun.com/javase/6/docs/api/java/sql/Connection.html (it'll > be better if it is displayed in frame) when I click (or by any other > action) on the word "Connection" in my code. Thomas already pointed out the correct approach.

I got it working now. The only step I missed before was to press shift-F2. By the way, do you know how to get Firefox to work with Eclipse and recognize the space in "file:/c:/Program Files/..."? Firefox only reads "file:/c:/Program", and I tried to put quotes around the location string in eclipse, it doesn't work.

Interestingly, it works for me without encoding the space I have WinXP Pro SP2 Firefox 2.0.0.4, Eclipse 3.2.2 (the Web Services version), In Eclipse my rt.jar "Javadoc location" has (*) Javadoc URL Javadoc location path: file:/C:/Program Files/Java/jdk1.6.0_01/docs/api/ I think I used the "Browse" button rather than type it in by hand. When I press shift-f2 Firefox shows the URL as (e.g.) file:///C:/Program%20Files/Java/jdk1.6.0_01/docs/api/javax/xml/validation/Validator.html > > wei schrieb: > [quoted text clipped - 22 lines] > When I press shift-f2 Firefox shows the URL as (e.g.) > file:///C:/Program%20Files/Java/jdk1.6.0_01/docs/api/javax/xml/validation/Validator.html Ian, I have the same versions of software as you do, and tried both approaches before I post my last message, none of them works with my local javadoc file 1. use %20 with/without quotes, eclipse shows "Location does not exist" 2. use browse button, eclipse is ok, but firefox showed the error 3. use web docs in sun site, works. I'd try to get away from it, since it needs internet connection. Thanks, Wei >>>wei schrieb: >> [quoted text clipped - 37 lines] > > Wei I suspect the problem is in the way Eclipse launches Firefox which is probably using WinXP file associations to launch your default browser. Windows on this PC launches 'Firefox URL's using DDE "%1",,0,0,,,, Maybe your registry entry lacks the quotes around %1? I used Windows Explorer, Folder Options, File Types to find this. Perhaps our history of updating Firefox/Mozilla differs and this lead to a glitch on your PC? > >>>wei schrieb: > [quoted text clipped - 48 lines] > Perhaps our history of updating Firefox/Mozilla differs and this lead to > a glitch on your PC? Ian, I checked the settings on my pc, and it's the same as yours. DDE "%1",,0,0,,,, with quotes around %1 and the application used to open html files is C:\PROGRA~1\MOZILL~1\FIREFOX.EXE -url "%1" -requestPending Do you think it's a setting issue in Eclipse?
