Can I ? - XSQL dynamic database connection

Question

[raised this a couple of days ago on the 9iJDeveloper forum - but that's vanished]
How do you write XSQL without knowledge of username and passwords.
The physical user will be supplying their DbUser and DbPassword in a
web login
page and these are to be used throughout the web application.
XSQL requires a connection alias. i.e. "demo"
<page xmlns:xsql="urn:oracle-xsql" connection="demo" >
<xsql:query max-rows="-1" null-indicator="no" row-element="USER"
rowset-element="" tag-case="upper">
select user from sys.dual
</xsql:query>
</page>
But I need to set the username and password for "demo" in runtime.
(Reason: Each database user has specific roles and limits on viewable
information)

Not with the default implementation of oracle.xml.xsql.XSQLConnectionManager and oracle.xml.xsql.XSQLConnectionManagerFactory, however I've worked with customers who have written a custom XSQL Connection Manager to handle connections in any way that's appropriate for your application. Some have used Oracle8i OCI8 JDBC's proxy connection feature, others have implemented a custom strategy.
The online documentation for XSQL (part of the doc for the XDK for Java on OTN that ships with the database documentation set) talks about the two interfaces above that your implementation must implement.
