Using url-generator for loading local files

Hi all,

I just got the latest stable Orbeon release (upgrading from 3.9), and am beginning a new app. In this app, I want to load local files (local means on the same server filesystem as Orbeon) from a cloned GitHub repo instead of from a REST interface.

I believe I have followed the url-generator examples, but I can't load the local files. I've been banging my head against this all morning, but I can't figure it out. It doesn't help that the HTML error page doesn't contain information about the problem like it used to, and even though I turned on logging, there's no log where I expect it.

In order to simplify my test case as much as possible, I created a pipeline in the page-flow which calls my XPL directly.

I have this path:

<page path-info="/nomisma/test/" view="xpl/load-id.xpl"/>

This is xpl/load-id.xpl:

<p:config xmlns:p="http://www.orbeon.com/oxf/pipeline"
    xmlns:oxf="http://www.orbeon.com/oxf/processors">

    

    <p:processor name="oxf:url-generator">
        <p:input name="config">
            <url>file:///usr/local/projects/nomisma-ids/id/augustus.xml</url>
            <content-type>application/xml</content-type>
        </p:input>
        <p:output name="data" id="xml"/>
    </p:processor>
</p:config>

Even if I change the <url> to a HTTP URL for an XML file that I know exists on the web, I'm just getting a generic "An Error Has Occurred." I expect /nomisma/test/ to just show an XML file in my browser. Am I missing something?

Thanks,
Ethan

Hi Ethan,

Last year we changed the default behavior so details about the errors wouldn't be sent to the browser anymore, and improved logging to the orbeon.log. See the rational for this change on:

http://blog.orbeon.com/2012/06/neat-and-informative-error-reports-with.html

But of course, it doesn't help if you can't see the orbeon.log. I think you should fix that problem first, otherwise you'll end up banging your head against the wall at every problem you find in your way :). The path to the orbeon.log is set in resources/config/log4j.xml and by default is ../logs/orbeon.log, so with Tomcat if you start ./catalina.sh from Tomcat's bin, the log ends up in Tomcat's logs. Maybe you can put an absolute path there?

https://github.com/orbeon/orbeon-forms/blob/master/src/resources/config/log4j.xml

I hope that after this, the error in the log will help. (For one you need to have a "data" output in your pipeline <p:param type="output" name="data"/>, and the URL generator needs to be connected to that output: <p:output name="data" ref="data"/>.)

Re: Using url-generator for loading local files

I had to fiddle around a bit with the logging settings (including changing the environment to dev), but I got everything working with loading files from the disk into my form.

Thanks!
