Compiling the Java API
Hi,
I'm relatively new to developing in Java, so this might be a very dumb question...
Recently, I downloaded the JDK and the source for the Java API and I've been trying to compile everything in java.util.
Frustratingly, I can't get all of the classes in java.util to compile straight off the bat.. Specifically, the classes Locale, Currency, JapaneseImperialCalendar and Calendar report a missing symbol error - either for LocaleData or OpenListResourceBundle.
I've tried hunting for the source for both of these classes, and also looked around the web to see what I could find, but found nothing. I've also looked for a class file or jar file that might be missing from my class path but I haven't found anything that looks useful.
So something in the configuration of what I'm doing is wrong - if anyone can offer any help on getting java.util to compile I would greatly appreciate it!
Thanks,
Chris

Why?
It has already been compiled for you.

If you just want to mess around try compiling java.util.regex. That might use just standard API classes.

Hi,
Thank you all for your help - unfortunately, I specifically want to compile collections because I'm wanting to play around with and change some of them a little, and I figure the first thing to do is to get them compiling "out of the box".
Any suggestions as to where I can get the full source from would be much appreciated, I'm sure that's a particularly dumb question, but nonetheless I have looked for that as well with no luck.
Alternately, I'm sure that, e.g., LocaleData.class exists somewhere, even if it's only in a part of the JRE I've downloaded - else code which uses the Calendar class could never work! If anyone has any hints as to where I might find these class files that would also solve my problems!
Thanks :)
Chris

You can't legally deploy the result of these modifications and compilations so what exactly is the point?

Maybe you can just extend the classes in question
or write wrapper classes to encapsulate.

A link was provided already.

If a class uses another class then it is really unlikely to run if the second class doesn't exist.Obviously the Java API runs.So I would guess that your real problem is that you are not building correctly.

Hello all,
* There was a link to the full source posted? Where? I *am* blind!
* Yep, agreed that there's definitely something wrong with the build process... any suggestions as to how I might fix it? I think it's my classpath that's missing something, but I haven't found, e.g., LocaleData.class in any of the JREs so... confused! If anyone can offer any help it'd be much appreciated! :)
Cheers,
Chris

First tell us why you think compiling the source yourself is a better option than just extending existing classes or using encapsulation.
