It would be telling in what way?
If I can't build ant on OS400, then there is a problem with ant on
OS400.
If I can't run ant on OS400, then there is a problem with ant on OS400.
I'd rather deal with the problem I'm having rather than a potential
other problem that I don't have to deal with.
In my book, the whole idea of Java is that you can create it on one
platform and then run it on many. It may sound selfish, but I'm not
interested in whether ant will build on OS400, mearly in trying to
figure out why it won't run.
I really don't see how trying to build it will get me any closer to why
it doesn't run.

Chris

I think Peter is right, Ant doesn't find java in the path it expects
it to be so it picks up the one from your PATH.
Where is the java executable (relative to JAVA_HOME)?

Correct.
There is also no jre hierarchy within JAVA_HOME.

I'm not sure what you mean by single jar.
There are four jars in the JAVA_HOME/lib dir: rt.jar, i18n.jar,
tools.jar and sunrsasign.jar.
I've copied the rt.jar file to a linux machine where I can easily disect
it, and lo and behold, it does have a java/util/Iterator.class file in
it.
So if you are asking whether rt.jar has lots of class files in it, then
yes, it does, inlcuding the ones that ant says it can't find.
This is getting interesting....

Just to clarify this for us. There is an rt.jar in JAVA_HOME/lib,
yes?
Is this a single jar and does it also contain the collections classes
(as you seem to have problems finding Iterator).

Ah yes. You see, Java installed in the object file system. The Unix file system entities
are just links. All the JDK's come installed. But you choose your Java in the object
file system. Look:

To clarify, I did an 'export CLASSPATH=<path>:<path>' with the relevant
paths to jar files in the jdk set, from the command prompt in qsh.
It made absolutely no difference to the output I got when I ran the
build script.

This may not be enough. If you look at the ant script
($ANT_HOME/bin/ant) that checks
where java is, it will default to the java on the path, if it cannot
find a java exe in the JAVA_HOME
directory structure. There is custom code for different platforms there
- but none for
OS/400.
What is the java on the path? (java -version should be sufficient).

Re: Problem on OS/400
Posted by Chris Wood <ch...@thesprocket.org>.
Further strangeness:
Our other OS/400 machine reports version 1.3.1 regardless of which java
binary you run (it has 1.1.8, 1.2 and 1.3 installed).
Have played about with renaming binaries to see if it's really running
what you ask it to run.
If I rename the 1.1.8 java binary, and then run the 1.3.1 java binary, I
still get the result of version being 1.1.8.
If I rename the 1.3.1 binary in addition to the 1.1.8 binary and then
try to run the 1.3.1 binary, I get file not found.
Have copied the binaries to linux and done a diff. They are the same
files. But why?
And more to the point, why does our other OS/400 box exhibit the same
behaviour, but with everything resolving to version 1.3.1 rather than
1.1.8???
Does anyone on here know OS/400 enough to comment?
Does anyone have more than one version of Java on their OS/400 and see
the same effect?
I'm going to try compiling ant on the box that resolves to 1.3.1 to see
what we get.

C.

Aha!
Now this *is* interesting:
>export JAVA_HOME=/qibm/proddata/java400/jdk13
>echo $JAVA_HOME
/qibm/proddata/java400/jdk13
>echo $PATH
/usr/bin:
>/usr/bin/java -version
qsh: 001-0014 Command /usr/bin/java not found.
> java -version
java version "1.1.8"
So, despite having a path set in qsh, it appears that it isn't used, and
it's actually some OS/400 magic that determines what binaries can be
seen.
And the icing on the cake:
> /qibm/proddata/java400/jdk13/bin/java -version
java version "1.1.8"
> /qibm/proddata/java400/jdk12/bin/java -version
java version "1.1.8"
Hum. Very strange. But is it an install problem with the jdks or
something very odd about the way OS/400 and/or qsh works?
Ok, I'm going to do a bit more research. We have another machine with
1.3 on it - I'll see what it says.
Thanks for the help so far guys, I'll keep you posted.

Yup, I understand this. The machine has 1.1, 1.2 and 1.3 on it, from the
packages supplied by IBM.
I had explicitly set the JAVA_HOME variable to the 1.3 version before
running the script.
I know little about the intricacies of OS/400 (I'm a unix man mainly),
but from a look at the files that comprise the jdk, there is no jre
subdirectory, so things do look rather different to what I'm expecting
to see.
I've not got much experience with IBM JDKs. Could this be a common
feature of them, or perhaps it's just OS/400 specific? I have access to
an AIX unix machine, so will do a bit of digging to see what things are
like there.

ANYTHING can happen on OS/400 :-) I'm uncompressing Ant 1.6.3 beta now on a machine with a 1.3.1 jvm.
If I don't run out of disk space doing so :-( I'll try to build it.

Ant 1.6 needs a 1.2 jvm, ant 1.5 and before is happy with a 1.1 jvm.

Ah, now we are making progress. It does appear, don't you think, that either
your installation is incomplete or the classpath is not properly set. Since you
say your installation works otherwise, one guesses that one of the ANT scripts
is setting the classpath incorrectly.

When you say "manually set" do you mean "by modifying the ANT build script(s)"
or "setting prior to the scripts' execution"? It should be the former ... see how the ANT
scripts work and modify them accordingly.
If I have time I will log into a friend's OS/400 box and try myself to build ANT. I'm a bit
busy but will try to make the time, I'm getting interested.

I got something similar when I extracted natively on OS/400 from a tar
package. However, I got round this issue by extracting on a linux box,
then repackaging using zip (jar would work too). This was then natively
extracted using jar on the OS/400. The odd thing about this is that if
you look at the files extracted with tar by using, say the the wrklnk
tool, then they look just fine - it's not until you actually try to
compile things that you get the error you mention above.
Had forgotten all about this problem until you mentioned it. Try as per
above to work around it.

Ok, I've had some time to try and get the source for beta3 compiled on
OS400.
Here's what I found:
I set the JAVA_HOME variable to be the path to the IBM-supplied JDK,
which is /qibm/proddata/java400/jdk13.
Tried to run the build.sh shell script. It won't run the bootstrap
script. This is a common OS400 qsh problem, as 'sh' isn't in /bin. I
modified build.sh to simply call 'sh bootstrap.sh', and this worked
around this problem.
I could then call 'sh build.sh' from qsh to run the build process.
I then get the two lines:
... Bootstrapping Ant Distribution
... Compiling Ant Classes
Just like I get on other platforms, such as Linux.
However, after a suitably OS400-sized pause, I then get a large stream
of errors.
The first one is:
src/main/org/apache/tools/ant/Project.java:65: Class java.util.Iterator
not found in import. import java.util.Iterator; ^
(sorry, wrapping has broken the effect on this somewhat. The ^ was
pointing to the j of java on the last line)
This sounds like a classpath issue to me, but I'm no expert. I've tried
manually setting the classpath to include the path to rt.jar which
should have this class. Note that the IBM supplied J2sdk is a little odd
- it doesn't have a jre directory - the rt.jar file is in the main lib
directory. Manually setting the classpath to this makes zero difference.

But if you *can* build Ant on OS/400, the problem is very much narrowed down.
Or if in building Ant on OS/400, you have little problems which you overcome,
they may add up to solving the big problem you have. And that is my hope
and expectation.

To build Ant, Ant has to run (there's a little Ant jar compiled in the Ant source
distribution). You build by running a script, build.sh .... please try it and tell me
what happens.
