Please read Wiki entry:
   This can be done with system properties ... or programmatically.

Hi Vadim,
I too have had trouble setting programmatic authentication for xindice.
Xindice 1.1b4 was up and running with no problems.  I had set up Cocoon's
cforms to write data to the xindice database using flowscript/xupdate.  It
was accessing the database over xmldb:xindice://localhost:8080/db.
The problem came when I enabled Tomcat's BASIC authentication on the
xindice directory, as recommended in the wiki entry
(http://wiki.apache.org/xindice/BasicAuthentication)
You recommend the code:
 driver.setProperty(DatabaseImpl.PROP_XMLRPC_USER, "xindice");
 driver.setProperty(DatabaseImpl.PROP_XMLRPC_PASSWORD, "manager");
However, driver is a protected field of DatabaseImpl
(http://xml.apache.org/xindice/api/org/apache/xindice/client/xmldb/DatabaseImpl.html)
and PROP_XMLRPC_[USER|PASSWORD] are private fields of DatabaseImpl
(http://cvs.apache.org/viewcvs.cgi/xml-xindice/java/src/org/apache/xindice/client/xmldb/xmlrpc/DatabaseImpl.java?view=markup).
 

Oops. My fault.

Trying to work around this, I set up some test code that included:
 try {
   String driver = "org.apache.xindice.client.xmldb.DatabaseImpl";
   Class c = Class.forName(driver);
   Database database = (Database)c.newInstance();
 

Correction:
   database.setProperty(
     "xmlrpc-password", "...");
   database.setProperty(
     "xmlrpc-user", "xindice");
   DatabaseManager.registerDatabase(database);
   String uri = "xmldb:xindice://localhost:8080/db";
 

One more:
   col = DatabaseManager.getCollection(uri);
   assert col != null;
 } ...
I believed that DatabaseManager would pass on the properties to
DatabaseImpl (the xml-rpc version), which would then pass them on to the
XmlRpcClient, but the output I get is
 

Well, I don't believe in this. I simply don't know what would happen 
with DatabaseManager properties. But I happen to know what happens with 
DatabaseImpl properties :-)


 trying to register database
 XML:DB Exception occured (error code: 0)
org.xmldb.api.base.XMLDBException: Cannot communicate with the server:
http://localhost:8080/xindice
Looking through the code
(http://cvs.apache.org/viewcvs.cgi/xml-xindice/java/src/org/apache/xindice/client/xmldb/xmlrpc/DatabaseImpl.java?view=markup),
I found the comment
 /* TODO: introduce authentication some day */
 

Please don't confuse basic HTTP authentication on XML-RPC protocol which 
is *global* to all databases deployed with per-collection authentication 
of XML:DB API. While former works, latter is not implemented yet, as 
well as user and role management.


Yet the code seems to be present
 XmlRpcClient client = new XmlRpcClient(xmlRpcURL);
 if (basicUser != null) {
   client.setBasicAuthentication(basicUser, basicPassword);
 }
 return client;
 

Yup.

Could you please give me some guidance on this?
 

Hope know things are clear. Feel free to amend wiki page with Java code 
snippet.

Thanks,
Vadim
