[Exist-open] RE: Please help!! Problem with XQueryGenerator

[Lung, J. <JL...@fr...>]

Ok, I think I have a solution to this problem.  Actually I believe it's =
because my setup is different than what the XQueryGenerator expects. =20

The XQueryGenerator provided with eXist connects to the local instance =
of eXist.  I put the exist-option.jar (and exist.jar) in my own web app =
and tried to use it from my own web app (which is using cocoon =
framework) to connect to a remote eXist instance.  It always threw the =
XMLDBException and complained that it couldn't get the database.  I =
reviewed the XQueryGenerator code and added the following lines before =
the DatabaseManager.getCollection() call:

this.collectionURI =3D parameters.getParameter("collection", =
"xmldb:exist://yoda:8080/exist/xmlrpc/db");
String driver =3D "org.exist.xmldb.DatabaseImpl";
Class c =3D Class.forName(driver);
org.xmldb.api.base.Database database =3D (org.xmldb.api.base.Database) =
c.newInstance();
DatabaseManager.registerDatabase(database);

It worked fine after I added these statements.  Still, I'm not clear why =
the XQueryGenerator didn't register a driver.  Maybe because the default =
is to connect to a local instance of eXist?  Any insight to this =
problem/solution, Wolfgang?

Laurent, please let us know if this solves your problem too.

thanks!!
