I have been attempting to use Xcode 1.5's new Java code sense to move
my development environment from NetBeans into Xcode. Well let me tell
you, it has not been a basket of roses.
After enabling Code Sense in Xcode I open up a new Java Swing project
(for example) and go to the main class of that project. I want to
import javax.swing.JFrame;
After typing in javax.swing. (both of which get correct completion
suggestions) I get a set of numbers, some comments from the header of
my file, and bunch of fairly useless stuff. Now if I type 'JF' I do
get a suggestion for 'JFrame', but shouldn't the Code Sense only show
what is in the javax.swing package? NetBeans does. Does anyone know
how I can repair this issue?
I'm afraid it isn't quite that easy with java. You need to work at it
a little bit. I've gotten it to work for me. I've yet to run into the
bugs mentioned in other responses, but I have neglected my coding a bit
of late... Anyway, quoting myself in a response from an earlier
date...
But there are two issues that people may run into that keep Java
code completion from working properly for the JDK classes:
1) If you were using index templates, they need to be rebuilt. See
/Developer/Extras/Xcode\ Index\ Templates/Index\ Templates\
ReadMe.rtf for instructions.
You might want to look inside that JavaIndex template too. Mine
didn't work because the classes.jar and ui.jar files were pointing to
the 1.4.1 installation that no longer existed. The following link is
very helpful when doing the indexing manually...
2) If you're using WebObjects, the JDK classes aren't indexed by the
index templates by default. The easiest way to do that is to add
/Library/Java/Home/src.jar to the projects, and the rebuild the
templates.
Isn't src.jar just source code? I could be mistaken though...
Anyway, I just copied the setup in JavaIndex and added the classes.jar
and ui.jar to my two WO templates. Just open them, add files, then
let Xcode finish indexing and move the .pbindex to the right place.
And while we are on the topic of WebObjects, I believe it is also
notable that the default system index template rules are backwards for
the WO indexes. The JavaDTWJavaClient index should be first in the
list since its framework specification is more specific than the
general WO index. As it is, the JavaDTW index never gets used because
the rules for the general index get called first. You can fix this by
duplicating the second entry in the default rules to your own
IndexTemplateRules.plist and putting that file in your Index Templates
folder. If you aren't working with Java Client apps though, well...
no worries ;-) Info on the rules system can be found in
/Developer/Extras/Xcode Index Templates/Index Templates ReadMe.rtf
Finally, the hint doesn't mention that for the Javadoc help indexing
to work, you need to make sure you have the latest Java Developer
package installed (available from connect.apple.com).
Definitely good advice here. The Xcode 1.5 ReadMe says it all.
Install 1.5 first, then the 1.4.2 update developer tools found at the
adc website. WebObjects users should also read the very bottom of the
1.5 release notes for instructions on fixing your WO help index if
necessary.
