Loading Resources In "Seperate Deployment"

Hi Orbeon experts,

I'm still trying to get the bookcast example running within a "seperate
deployment". This means I've copied the complete folder
"resources/apps/xforms-bookcast", including subfolders from "ops.war" to a
folder within my web app. When I request the bookcast example in the
browser, I get the following exception:


Type    class org.orbeon.oxf.common.ValidationException

        at com.sun.msv.reader.SimpleState.startElement(SimpleState.java:76)



I assume it is not a validation problem, but rather the schema XSD file
cannot be loaded. Surprisingly the context path of OPS (= ops_nightly) is
being appended to the context path of my web app (= mywebapp).

When I try to use the OXF protocol instead
(oxf:apps/xforms-bookcast/schema.xsd), I get an ResourceNotFoundException:


Type    class org.orbeon.oxf.resources.ResourceNotFoundException
Message Cannot find resource apps/xforms-bookcast/schema.xsd

        at org.orbeon.oxf.util.NetUtils.getLastModified(NetUtils.java:146)


Referencing the schema with an absolute path
(oxf:/apps/xforms-bookcast/schema.xsd)  seems to work. But I'm not sure from
which web app the resources are loaded (ops or mywebapp)!?

In what way do I need to change the paths for the images to get the loaded
by  the  browser?  Is it possible to use relative paths for images and other
resources, to avoid conflicts when moving an application to an other folder?

Thanks in advance for your help!

Hi BitByter,

Do you have an explicit reference to schema.xsd in your code? Where is
it? Is it an absolute path?

Hi Alex,

as I mentioned, I simply copied the complete bookcast example that is being
packaged with the ops.war and then just referenced/loaded the view.xhtml
file from my webapp. So the XSD schema is referenced like this:

<xforms:model schema="/apps/xforms-bookcast/schema.xsd">

From which location are resources (images, xsd, etc.) being loaded when a
"seperate deployment" is used?

Bitbyter,
    /apps/xforms-bookcast/schema.xsd

would be /mywebapp/WEB-INF/resources/apps/xforms-bookcast/schema.xsd

does this file exist?

Hi Ryan,

no, the file /mywebapp/WEB-INF/resources/apps/xforms-bookcast/schema.xsd
does not exist at this location. I've corrected the path to the XSD schema
like this:

<xforms:model schema="/xforms/xforms-bookcast/schema.xsd">

And this XSD schema now is available via the URL
http://localhost:9090/mywebapp/xforms/xforms-bookcast/schema.xsd

Unfortunately when I load the "view.xhtml" page which references this XSD
schema as above mentioned, I still get the following exception:

Type    class org.orbeon.oxf.common.ValidationException

For some reason Orbeon Forms (OF) seems to automatically prepend its own web
context (= ops_nightly). So how do I get this bookcast example running in a
"seperate deployment"?

I further noticed that OF seems to look up reasources always in its own
location where it has been deployed when using the oxf: protocol. Is this
correct? This would mean that oxf: could not be used in a "seperate
deployment".

BitByter,
    Well oxf: protocol definitly works in a "seperate deployment" as I use it all the time. Have you tried searching your mywebapp folder for ops_nightly being referenced anywhere? thats the only reason I can think that it would try to access that

Well  not with the nigtly build from 2007/04/07 that I currently use. When I
reference the XSD schema like this:

<xforms:model schema="oxf:/xforms/xforms-bookcast/schema.xsd">

And when I then copy '/xforms/xforms-bookcast/schema.xsd' to the folder
WEB-INF/resources of the OPS web app, then the XSD schema is found. But when
I copy '/xforms/xforms-bookcast/schema.xsd' to the WEB-INF/resources folder
or  directly  to the web app root folder of mywebapp, the XSD fails to load.
So I am really astonished that it works somehow for you. Maybe you are using
a different servlet filter or something else?!

So did you get the bookcast example running in your "seperate deployment"?

Mywebapp  is  the  context name, respectively root folder of my web app. The
only  place  where  "ops_nightly" is mentioned is the deployment descriptor,
where the Orbeon filters are defined:

   <filter>
      <filter-name>ops-xforms-filter</filter-name>
      <filter-class>org.orbeon.oxf.servlet.OPSXFormsFilter</filter-class>
      <init-param>
         <param-name>oxf.xforms.renderer.context</param-name>
         <param-value>/ops_nightly</param-value>
      </init-param>
   </filter>
   <filter-mapping>
      <filter-name>ops-xforms-filter</filter-name>
      <url-pattern>/xforms/*</url-pattern>
   </filter-mapping>
   <filter-mapping>
      <filter-name>ops-xforms-filter</filter-name>
      <url-pattern>/ops/*</url-pattern>
   </filter-mapping>


Really strange all that.

I haven't used the bookcast example, but I have used oxf: successfully. Have you tried changing ops_nightly to your own context?

Try looking at http://www.orbeon.com/ops/doc/reference-xforms-java#d123e56 it goes into some essential details for setting up Orbeon for JSP

Yes, but this doesn't work as then Orbeon servlet filter then would forward
the XForms processing to my web app - as far as I understood the
documentation.

Could you maybe post a very simple example that works for you. Maybe one
where an image is used as a button or something similar?

Maybe just to make things clear: you have deployed two web application in
your web container (Tomcat). First "ops.war" and then your real application,
let us name it "myapp.war"? And all resources (images, etc.) which are
refernced in "myapp.war" are also packaged in "myapp.war" and are not
contained in "ops.war"? And which filter (class) of Orbeon Forms do you use?

Yes,  I've  read that document and followed the instructions. But I would be
great  if it could be expanded with a concrete example. Maybe porting/moving one of
the XForms examples to an external web application.  :)

BitByter,
    I believe what the exception is thrown because the file cannot be found, when OPS can't find a file it will return a 404 Not Found page which is HTML, hence the element "html" is not allowed here!

So its still not finding the url. I think I have perhaps go a bit mixed up with how your trying to access this, do you have an app under the context of ops_nightly? which contains the bookcast app?

No, I got an seperate web application with its own WAR file, where Orbeon
Forms is not included. Orbeon Froms (/ops_nightly) is deploy in the same web
container separately (thus "seperate deployment"). I just delete all the
sample applications from resources/apps folder from the "ops.war" to avoid
accidently accessing those.

This  means  my  web  application is not located within the /ops_nightly web
app, respectively "ops.war".

OK, thanks for that information, so that I do not need to try out any

Yes, that's what I thought too. :)   So do you have any idea when a fix might
be available with a nightly build, because this is something essential for
my further work with Orbeon Forms?

I will try and use that while waiting for a fix.  :)

This workaround works for XML resources, but it does not work for images.
When I use an absolute path like
http://localhost:9090/mywebapp/xforms/xforms-bookcast/images/save.gif for the save
button, following error page is generated by Orbeon Forms:

So this seems as if it is not possible to place images or any other binary
resources beneath the folder of the application itself, in this case beneath
the "xforms-bookcast" folder. As a workaround I've moved the images to a
folder which does not trigger the Orbeon Forms servlet filter. Is this going
to change, or is this drawback going to stay for "seperate deployments"?

Furthermore when I look at my Tomcat access log, I currently get the
following entries when I access the bookcast example once:

127.0.0.1 - - [16/Apr/2007:10:24:52 +0100] "GET /mywebapp/xforms/xforms-bookcast/schema.xsd HTTP/1.1" 200 1771

So there are four resource which are servered with an HTTP status code 404
(file not found). Those are some JavaScript and CSS files, which non is
explicitly referenced by the "view.xhtml" file of the bookcast example. I
assume that at least those JavaScript stuff is mandatory to get Orbeon Forms
work correctly. Is there any way to make these necessary files also
available in a seperate deployment?

And by the way, am I the first to use Orbeon Forms for a seperate
deployment? Currently I'm really wondering how all others successfully
integrated Orbeon Forms into their existing web applications.

I think that everything under /xforms will go through the filter,
which will perform the forwarding the Orbeon Forms web application,
which in turn will assume that what it gets is XML. So if your
web.xml, you map /xforms to the Orbeon Forms filter, then you should
make sure not to have any image under /xforms. Have you tried moving
the images under say /images?

You might very well be one of the first to use this feature! Separate
deployment is a new feature, which is only included in the nightly
builds. But this is a feature that we are planning to support in the
long term, as we think that "separate deployment" is a better option
than the "integrated deployment" for more complex applications.

Yes, that's what I meant. Probably I was not clear enough. So it is not
possible to keep binary resources (images, pdf, etc.) in a subfolder of the
xforms app. It's not nice, but I could live with that.

But do you have a workaround or solution for the problem that all the
JavaScript and CSS stylesheets which are loaded implicitly ('xforms-min.js',
'orbeon.css', 'xforms-min.css' and 'xforms-widgets.css') by Orbeon Forms
currently can't be loaded with a "separate deployment"? I assume that at
least without the JavaScript stuff, all the XForms processing won't work.
Thus, currently this seems to be a no go for a "separate deployment". Isn't
it?

It is fixed now! It should make it to an automatic build soon. I also
attach a JSP version of the Bookcast example, which loads schema.xsd
from the same location and also fixes a few paths to work in separate
deployment mode.
