relative URLs to other applications within tomcat

Hi everyone,

I want to use Orbeon as an interface to my standalone eXist installation, not the one included with Orbeon.  Both Orbeon and eXist are installed underneath tomcat, and are located at /ops and /exist, respectively.  The problem is that whenever I use a relative URL with an absolute path to exist (ie, href="/exist/rest/db/foo.xml"), it doesn't find the file.  

The causes seem to be twofold: 1) /exist is mapped to orbeon's exist installation, 2) orbeon rewrites all absolute paths as relative to orbeon, not the server itself.  I tried using f:url-norewrite="true", but this only worked in xforms, not xpl.  I'm guessing this is because the URL rewriter only works on xforms pages. I'm not sure, then, where I can reconfigure the way that XPL deals with absolute paths.  

Is there any way I can map /exist to the server-relative /exist instead of something underneath /ops, and have it stick for all URLs used by orbeon, both in xforms and xpl?  

Thanks a bunch,
~James

Hi,
i worked with an external eXist-DB too, but the only way i could make this
work was to explicit name the server-path, i.e.
http://localhost:8080/exist/... instadt of the realtiv path /exist/...
I wrote my important paths to an extra instance which i include to all pages
so when i change the server, i only have to change one config-file and all
will work well again. HTH

I assume you are using the href attributes on p:input? Is that the use
case which is failing?

In XPL, absolute paths in p:input/@href will be interpreted relatively
to the base URI of the XPL file, which is probably a URL like:

   oxf:/path/to/my.xpl

So you will get a resulting URI which is an "oxf:" URI, not an "http:"
URI. One workaround would be to use an absolute URI.

One thing you can do is use the oxf:xforms-submission processor to
retrieve the data instead. This way you can, on the submission, use
f:url-norewrite="true".

The drawback is a little more code to write, and a probable
performance impact.
