org.xml.sax.SAXParseException: Content is not allowed in prolog.

[Leo <le...@tstt.net.tt>]

Hi folks

The Error:
org.xml.sax.SAXParseException: Content is not allowed in prolog.

Steps being performed:
I have a page store.xsp which attempts
to store a sample document(beet.xml) into the eXist database.

Storing documents works fine in eXist so I know it works
(this is done via xadmin.xsp)

I have copied the relevant code into my document store.xsp.
I know I am connecting to the database, because I have
a drop down list which is built from items in the database.

But I get the following error when attempting
to access the same code that works in eXist directly.
The following Code snippet from store.xsp generates the error.

<xmldb:collection>
	<xmldb:uri>collectionURI</xmldb:uri>
      <xmldb:user>user</xmldb:user>
      <xmldb:password>passwd</xmldb:password>
      <xmldb:store>
               <xmldb:name>fileName</xmldb:name>
               <xmldb:source>source</xmldb:source>
               <xmldb:overwrite>overwrite</xmldb:overwrite>
      </xmldb:store>
      <xmldb:error>
                <error>Error: <xmldb:get-error/></error>
      </xmldb:error>
</xmldb:collection>


I think the source of the problem is:

Hi folks

I have been making progress in my quest to have eXist
working inside forrest.

I am able to simple things such as retreive xml documents
and listing of collections.

However when I attempt to add a document: Introduction.xml, which
validates and displays correctly in Forrest
to the database, I get the following error

I don't think eXist is returning the XML correctly.  Content before the
prolog means characters before the <?xml version="1.0"?> bit.  If you
remove that from beet.xml you might have better luck, although that
doesn't solve the real problem.

Anyway, you're likely to find many more eXist users on the
users@cocoon.apache.org list than here.  There's a Cocoon Wiki page as
evidence that somewhere there knows how to do it:
