Orbeon issues with Exist (and solution?)

Hi everybody,

Just writing about an issue we've had with Orbeon and our solution, any
other proposals are welcome.

I'm using Orbeon as a piece of Muradora (a GUI for Fedora repository).
We deploy Orbeon 3.6.0 on Tomcat 6.0 using Java 6.0 under a Debian
environment. We've got some serious issues with Orbeon, that have been
traced to Exist, the xml database.

While starting tomcat we saw in log files complains of Orbeon (exist, in
fact) about missing jar files (xalan and xerces). Seems Exist does the
check for specific versions (like 8.9.0.3) so if you include other
versions (8.9.0.4 or 9.0 for example) it complains.

Also, if you put wrong version of the libraries, when you stop tomcat it
remains in memory, consuming CPU and resources and has to be killed
manually.

We've solved that adding XercesImpl.jar , from Xerces 2.8.1 and
Xalan.jar, from Xalan 2.7.0 into WEB-INF/lib, and rebuilding the war
files. Now Orbeon and Exist work perfectly, no complains.

That's all, comments welcome,
Pere

Pere,

Thanks for this feedback.

Another solution is to deploy eXist either as a separate WAR, or as a
standalone database. This will avoid JAR conflicts related to eXist.

Re: Re: Orbeon issues with Exist (and solution?)

Hi Erik,

Can you please give details about what config changes are required to set up
eXist as a separate WAR (not sure what's implied by having it as a "separate
database"). I'm facing related issues with those JARs - on one application
server whose classloading policy is always "parent-first", those JARs are
ignored and thus break eXist. Any leeway that I have might be useful.

Incidentally, if you hear anything about eXist having this packaging mess
fixed, please post it to the list.

Thanks,
JL

Jean-Luc,

eXist comes with a WAR file, which you can deploy in your Servlet
container.

There are two main uses of eXist in Orbeon Forms:

1. Built-in, for storing XForms state information.

For this mode, and if the eXist embedded with Orbeon Forms doesn't
work at all, you will have to modify the following appropriately in
properties.xml:

<property as="xs:string"
name="oxf.xforms.store.application.username" value="guest"/>
<property as="xs:string"
name="oxf.xforms.store.application.password" value="guest"/>
<property as="xs:anyURI"
name="oxf.xforms.store.application.uri" value="xmldb:exist:///"/>
<property as="xs:string"
name="oxf.xforms.store.application.collection" value="/db/orbeon/
xforms/cache/"/>

The default setting for the URI, "xmldb:exist:///", means the embedded
database, which is not what you want. You will have to modify the
above to point to your version of eXist, and use the proper username/
password.

2. Custom, from applications, like the Governement Forms example.

In that case, it will be up to you to use the proper URLs to point to
your version of eXist. Currently, the Governement Forms is not
configurable through properties, but we are working on that in the
context of our Form Runner effort.
