Hi,
I installed (last month) Eclipse PDT All-in-one (Ganymede), and it works
fine (to PHP development). There is JRE 1.6 in my PC.
I would like to learn Java and I tried to enable Java plugin in Eclipse
(to create Java projects, Java source files, etc) but it failed. In 'Help
> Software Updates > Installed Software' section I can't see anything
about Java plugin (which is the basic Java plugin in Eclipse? I guess it
is the JDT, isn't it?). I tried to enable JDT on the 'Avaible Software'
tab (I selected the 'Eclipse Java Development Tools' and clicked to
Install button) but it stopped at all times until downloading. I tried to
download manually, but it failed too. (My internet connection is OK in
other cases!)
Am I doing something wrong, or there are other problems?
Thanks, Adam
[sorry to my English]

Hello Derek,
I understand but it is not there! :) That was my first idea, but there are
neither in the File / New menu nor in Project Explorer window (including
right click)! I browsed the Program Files\Eclipse\plugin folder, and there
are the files of JDT, but in Eclipse is not any trace of availability for
create Java projects.
Since then, I tried to install JDT again in Eclipse Software Update
section, and it succeeded! Everything works fine!
Thanks, Adam
Ps: Please, somebody tell me, which is Eclipse's basic plugin for simple
Java SE development! Thx.

You've got the right thing, JDT.
By the way, because the update can use mirror sites, sometimes those
mirror sites are unreliable. That is probably why your first attempt at
installing JDT failed. I wish that Eclipse didn't have to rely on
mirrors, but I think that is the only way they can keep up with the
demand for downloads and updates - remember that Eclipse Foundation is
non-profit and has limited resources.
Hope this helps,
Eric

All the org.eclipse.jdt.* plug-ins, for example, org.eclipse.jdt.core,
org.eclipse.jdt.ui, org.eclipse.jdt.apt.core, ... there are about a dozen in
all. There are also some other plug-ins that the org.eclipse.jdt.* plug-ins
depend upon, that are included in the JDT package.
If you have org.eclipse.jdt.ui, then you probably have all the others as
well.
Make sure that you are running Eclipse on a 1.5 or higher JRE (check your
Help -> About -> Software Configuration to be sure). It will run on
lower-level platforms but not all functionality will be available.

Oh, some more things:
1. I know you said in your first post that you have a 1.6 JRE, but you
should really check in Help -> About -> Configuration Details to be sure
that is the one that is getting used, and if you are running on Linux make
sure that it is a Sun JRE (not gcj).
2. Check the error log (Window -> Show View -> Error Log, or you might have
to look inside the PDE Perspective, or just look with a text editor in
[workspace-directory]/.metadata/.log) to see if there are any errors being
reported.
