Thanks for the quick responses Thomas and Marco. It looks like there
might be an issue with the 32-bit OpenJDK. I'm going to stick with
the SUN JDK for now since it's working well so far.

Thanks again!

Ah-ha. Beat me by five minutes. :-)

Glad it's working for you now - we'll have to look into what needs to be
done to get it working on the OpenJDK.

I have Axiom Stack running on OpenJDK.
java version "1.6.0_0"
OpenJDK Runtime Environment (build 1.6.0_0-b11)
OpenJDK 64-Bit Server VM (build 1.6.0_0-b11, mixed mode)

You're probably running into the issue below. It's the only I had when
getting set up.

Mike,

It sounds like there's something strange going on with Rhino. The
unquoted XML you see in the axiom-generate.js is a language feature of
Javascript 1.6 called E4X:
([link]) - XML can
be expressed as a literal and treated as a first-class object. I

Figured it out... switching to the SUN JDK fixed it. It didn't like
the OpenJDK at all:

java version "1.6.0_0"
IcedTea6 1.3.1 (6b12-0ubuntu6.5) Runtime Environment (build 1.6.0_0-
b12)
OpenJDK Server VM (build 1.6.0_0-b12, mixed mode)

I'm trying to setup axiom stack and just run the manage app and it's
erroring out right away.

I expanded the tar for axiom stack 3.2.9 and started the server by
running "start.sh". Everything appears to come up ok and I go to
[link] with my browser. From there I select the
"manage" link. At which point I get the following error:

Maks,

There are a few methods that can be used here.
getObjects
getHits
getHitCount

The reason getHits adds those fields is because it's supposed to bring
back the ids. I'll look a bit closer at the internals and let you know
what I see.

Re: [Axiom Stack] accessing sql db

But it does kind of make sense, as its just way to get how many
matches to a query instead of having to fetch all matching objects
into mem (as array) and then getting .length
And the sql its generating 'select count(*) is what i'd expect, its
just adding the columns names, which is what causes the error.

New Axiom Stack Demo Application - Twax

2009-07-24T20:53:44Z

We wanted to announce that there is a new demo application in the
axiom-demos ([link]) repository.

In case you couldn't guess from the subject, the application is called
Twax which is short for Twitter on Axiom [Stack] (reimplementation,
not using the Twitter API). Feel free to fork it and try it out. The

Maks,

Hits is actually a feature of Lucene and I'd be surprised if you had
said it worked with a relational DB. We should probably fix up the
messaging and error out if your using it with non-Lucene objects.

Basically Hits are just pointers to the document rather than the full
document. When using Lucene it requires less memory and less

Hi Nick,

Thanks for that.
Yep, "dbsource.type = relational" did the trick.
app.getObjects() works fine now, but app.getHitCount() causes an error
as it seem to generate invalid SQL,
eg.
SELECT COUNT(*) TITLE, ISBN FROM BOOKS
java.sql.SQLException: Column 'BOOKS.ISBN' is invalid in the select

Maks,

Sorry in the delay. I've put up a repository on Github that will hold
all of our "Demo" type applications so be sure to look back there for
more from time to time. The demo's are meant to be purely for
reference.

The code lives at: [link]

That said, I think I figured out what was going wrong. Most of the

Maks,

That isn't the way that it should be working in Axiom Stack.

Typically my test cases with H2 have been in using the internal DB (we
have H2 working with Lucene internally), and that has always worked
for me without issues.

But, I'll throw together an example application tomorrow to see what I

Re: accessing sql db

Hi Nick,

I'm afraid its still not working.

From what I can see looking through the axiom src and comparing to my
log files, it looks like only a query to the lucene index is being
run.

I should actually explain that what I'm trying to do is read data in
the sql db that was not added via axiom app, so it would not have any
