ResourceNotFoundException: Cannot load "/forms/my-app/service/new.xpl" with webapp loader

Greetings,

I've got strange behaviour using Orbeon forms server recently.

Sometimes the forms are submitted correctly, sometimes not with no obvious reason.
Moreover, the problem seems intermittent, unpredictable

The errors are the following :

2012-02-24 10:29:52,551 INFO  OrbeonSessionListener  - Session Listener - Session created.
2012-02-24 10:29:52,730 INFO  ProcessorService  - /fr/service/custom/my-app/new - Received request

and

What are the "/forms/my-app/service/new.xpl" and "/apps/search/page-flow.xml" files?
 (XPL stands for Xml Pipeline Language) What are their purposes?

So I've checked, these files were not there (in the webapp folders), but the app was running well before without those files.

Does anyone has encountered this kind of problem or has an idea or hint in order to debug that?

Any help will be appreciated!

Greetings,

Do I have to conclude that nobody has any idea about what is happening with ResourceNotFoundException: Cannot load "/forms/my-app/service/new.xpl  and "/apps/search/page-flow.xml" errors?

Or maybe post something on Friday afternoon was a very bad idea ;-)

Any help, hint or pointer to documentation wil be appreciated!

Claude

Claude,

That is definitely funny, because I have never seen these errors, at
least not in such a random way!

Is there, by any chance, a form whose app/form name includes "new"
and/or "service" or maybe "custom"?

Here is the page flow which matches on paths:

https://github.com/orbeon/orbeon-forms/blob/master/src/resources/apps/fr/page-flow.xml

More specifically, the entry that seems to hit:

https://github.com/orbeon/orbeon-forms/blob/master/src/resources/apps/fr/page-flow.xml#L153

In order for this to match, the URL would have to be:

/fr/service/custom/my-app/new

But still, I don't know how that URL could occur randomly.

Greetings Eric,

Thank you for the answer!

I agree, it's pretty strange... ;-(
So it's why I've decided to post my problem in order to get « expert's» advice on it.

You give me some useful clues, I will look forward and keep you informed of my progress.

Many thanks again!

Claude

No, I’ve checked

You definitely score a point here.

After looking at the XML code of page-flow.xml, I’ve concluded that « my-app » should come from Orbeon which I guessed could be a « default value » from the matcher when it failed or something else. There is no « my-app » chain in our entire project.

Maybe the error comes from the « redirection » mechanism we used to store a copy of the form in an outside repository. In order to do that we have just modify the properties-local.xml configuration file.

<property as="xs:anyURI" name="oxf.fr.persistence.app.uri.*.*.data" value="http://localhost:8080/epm-client-test/OsylEditorEntryPoint/OrbeonRedirect"
<property as="xs:anyURI" name="oxf.fr.persistence.app.uri.orbeon.*.data" value="/fr/service/exist" />

Does this mean something to you?

Thanks again for your help!

Claude

Unfortunately I still don't see how or why this is happening :(
