| 3.0 FCS: can't step into the JDK [message #165970] |

I've just installed 3.0 on a machine which has never had Eclipse before.
I'm debugging the following fragment (with the default settings):
String urlString = ". valid url ."
URL url = new URL(urlString);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
InputStream is = con.getInputStream();
StringBuffer buf = new StringBuffer();
int c;
while((c = is.read()) != -1) {
buf.append((char)c);
}
The code works fine. I press F5 (step into to debug). I do NOT step into
any of the JDK. I do not have Step Filtering turned on (when I drop the Run
menu there is no checkbox associated with "Use Step Filters"). Pressing F5
is no different from pressing F6 - I do not step into any of the JDK methods
shown above. I believe I've tried various settings of the toggle and the
checkboxes from Preferences->Java->Debug->Step Filtering and none appear to
work. What am I doing wrong? I must be missing something obvious!
Thanks,
Russell

When you install the Sun JDK you get two installs, one is the JDK and one is
the JRE. Unfortunately the JRE one (c:\Program files\...) is the one that
gets put in the registry so it's the one Eclipse picks up on, and it has no
sources. Two solutions:
1. Use the -vm argument to eclipse.exe to force it to use javaw.exe from the
JDK, or
2. Inside Eclipse use Window > Preferences > Java > Installed JREs, Click
Add, and teach Eclipse about the name and location of the JDK. For example,
JRE Name: JDK 1.4.2_04
JRE home directory: c:\j2sdk1.4.2_04
Everything else should be filled in for you so press OK.
Then put a check mark next to the new JDK. Press OK again.
Everything should rebuild and you should have full source and javadoc for
the Java run-time libraries.
Some people prefer the first solution (even Eclipse doc recommends it) but I
like the second one for some reason. YMMV. I believe there's a bugzilla
entry open on this to always pick the JDK no matter what the registry says.

Yes, that was it. I had not told Eclipse about the availability of the SDK
and it got the JRE from the registry. Once I pointed it to the SDK all was
well. It's been so long since I'd installed Eclipse on a machine which
didn't have one that I'd forgotten this step.
Thanks to all who've posted suggestions.
