PDF function throws error when custom css is invoked through servlet

Hi guys,
We have a need to externalize custom css files out of the Orbeon war and
into the file system. For that purpose, we have created a servlet that
allows us to access the external css file. We then use the *property*
element: *oxf.fr.css.custom.uri.orbeon.** of the properties-local.xml to
invoke the servlet *url*. Here it is:
<property as="xs:string" name="oxf.fr.css.custom.uri.orbeon.*"
value="http://localhost/orbeon/external/stylesheet/customer-style.css"/>  

The above works well however we have noticed an unfortunate side effect: it
breaks the *pdf*  button functionality.
Instead of having the usual print preview page, we have an "An error has
occurred while processing the request."
Unfortunately the stack trace does not give much indication of what the
problem could be. Here it is:

Hi Disanka,

Sorry for the late response! If this is still an issue, can I ask if you're
using Tomcat? If you are, there is a simple way of externalizing resources,
without making any change to the Orbeon Forms war, by adding the following
inside the <Context> for Orbeon Forms, in your Tomcat's server.xml:

<Parameter override="false"
           name="oxf.resources.priority.0"
         
value="org.orbeon.oxf.resources.FilesystemResourceManagerFactory"/>
<Parameter override="false"
         
name="oxf.resources.priority.0.oxf.resources.filesystem.sandbox-directory"
           value="/path/to/external/resources-local"/>

Then you can put inside that path (`/path/to/external/resources-local`),
whatever you would put in the `WEB-INF/resources`. Would that work for you?
