We have recently installed Orbeon Forms stable 3.8.0 CE’s orbeon.war and that works out of box.

Because some features do not work in the stable version we installed the CE nightly build orbeon-CE.war, but this one does not work out of the box.

Form builder has some exceptions. Not only the builder fails but the examples too, so Form runner too.

Java exception

java.lang.NullPointerException
class: java.util.zip.Deflater
method: ensureOpen
line: 421

We are using Linux Debian Lenny 2.6.26-smp, Tomcat 5.5.

Probably we are running into some undocumented requirement for this nightly build…?

    Problem identified and workaround:

    We use IBM java 1.5 and this is what we found.

    Orbeon stable works OK with IBM java 1.5, Orbeon nightly does not work with IBM java 1.5, see previously mentioned zip error.

    We then installed SUN java 1.5 and Orbeon nightly works OK with SUN java 1.5., but first there was a problem:

    *Exception in thread “exist_QuartzScheduler_QuartzSchedulerThread” java.lang.OutOfMemoryError: PermGen space*

    And we googled up this thread:

    http://orbeon-forms-ops-users.24843.n4.nabble.com/Data-lost-on-quot-Save-Document-quot-td40450.html

    The permgen space is a separate VM
    setting. It can be increased with a
    VM option, e.g.:
    -XX:MaxPermSize=128m

    Which solved the problem.
