Hi Jim,
Thanks for your reply. I took a look at your
example and the first problem was simply that I didn't include the Map factory
support in the 0.2 release, because I didn't think it was very usefull and I
wanted to test it a little more. Anyway, I have it working in my CVS working
copy and I will make another release including this soon.
After correcting this no exception is thrown. But
the XSLT template is not running correctly, presumably because the XML generated
by JXV is not the same as that generated by Domify. If you could show me a piece
of XML code demonstrating what type of XML you expect to get, I can configure
JXV to produce it.
p.s. I came across a suspicious line in
the maverick config file:
<!-- set default-transform-method to
"dom" to use dom instead of sax-->
<view-factory type="jxv"
provider="org.infohazard.maverick.opt.view.JXVViewFactory"
default-transform-method="sax">
You don't seem to close this config element. I
guess you had it right in your working copy but forgot to pack the correct
version in the JAR.
By the way, in the view factory you don't have to
check for nulls. JXV handles them.

Hi Gal,
I started playing around with making a custom
view for Maverick that uses JXV but it seems to blow up pretty readily (JXV
that is, not the custom view).
If you want to see how far I've gotten, you can
download what I have here and play around with it:

Subject: [Mav-user] Java XML View
open source project
Hello all.
I have recently released version 0.2 of JXV,
an open source project aimed to convert Java objects into "XML views". JXV
supports the same type of dynamic DOM tree implemented in Domify, and also
implements a SAX-based approach which is usually more scalable. Here is a
copy of the release announcement:
-- start of quote
I am pleased to announce the first public
release of JXV.
JXV is a library which allows for Java objects to be
given "XML Views", and for those views to be read back into objects. JXV
supports both SAX and DOM output, and can read XML input from any
SAX-compliant parser. Resulting DOM trees are dynamic, and reflect changes
made to the object model even after they were created. JXV fully supports
namespaces in it's XML views, and can correctly parse and read XML content
with namespaces.
JXV uses a pluggable architecture which allows
XML view factories to be configured and loaded at runtime. The JXV
configuration mechanisms also leverage XML namespaces to allow the
configurations for those different view factories to be inlined within the
JXV configuration file. In this release, JXV comes pre-configured with
view factories for JavaBeans, collections, array, and "flat objects" such
as Strings, primitives, etc. These factories support a wide variety of
configuration options, and are sufficient for most object models. Future
versions of JXV will include pre-configured support for additional
factories. JXV may also release special-purpose factories (such as ones
providing views for RowSets, ResultSets and other JDBC structures) as
extension packages.
JXV is open-source and freely available in
both source and binary form. It is covered by an Apache-like license (see
information at the project page). The JXV distribution contains a compiled
binary version as well as a buildable "src" dir (Ant is required to use
the build script).
-- end of quote
Note that shortly after this release I had
released version 0.2 with minor documentation improvements and JDK1.3
support (previous version depended on 1.4 for some exception-related
classes).
I think JXV can be put to good use in
Maverick. I would be happy to try and help the Maverick developers wire
JXV into Mavericks existing architecture. If anybody is interested in
trying this, please contact me. Also any questions/comments/suggestions
are welcome.
Regards
Gal
