Where are the FTP files in the XDB?

Question

Hi, I can 'MPUT' a bunch of files into the XDB. But exactly where are they and how does XDB handle them? If I query the dba_objects view from sql*plus, I can not see them. Also, how do I refresh a HTTP connection to the XDB? The first time I connect, it ask me for password. Then I think the browser somehow cache the connection, so everytime I go back I see the same folders and objects, even if I close and reopen the browser. Thanks!

John,
valid XMLSchema-based documents are stored in the default table specified in the XMLSchema. Other types of files are stored as LOBs. Further, which browser are you using? Internet Explorer version 6 should be ok - 5.5 has caching issues.
This extract from the XDB Demo whitepaper explains the repository:
All the meta-data required to manage the Oracle XML DB repository is stored in a database schema owned by the database user XDB. This user is created as part of the Oracle XML DB installation procedure. The primary table in this schema is an XMLType table called XDB$RESOURCE. The table contains one row for each file or folder managed by the Oracle XML DB repository. The documents in this table are referred to as resource documents.
The XDB$RESOURCE table is not directly exposed to the SQL programmer. Instead the contents of the repository are exposed via two public views, the RESOURCE_VIEW and the PATH_VIEW. The RESOURCE_VIEW and PATH_VIEW provide the SQL programmer the ability to access and update both the meta-data and content of a document stored in the Oracle XML DB repository.
Both the RESOURCE_VIEW and the PATH_VIEW contain a column called RES. This is an XMLType column that can be used to access and update the resource asscociated with a udocument stored in the Oracle XML DB repository.
When Schema Based XML documents are stored in the Oracle XML DB repository the document content is stored as an object in the default table identified by the XML Schema. The repository contains the meta-data about the document and a pointer (REF of XMLTYPE) that identifies the row in the default table that contains the content.
It is also possible to store other kinds of documents in the repository. When non-xml and nonschema based XML documents are stored in the repository, the content of the document is stored in a LOB alongside the meta-data about the document.
The supplied PL/SQL packages DBMS_XDB, DBMS_XDBZ and DBMS_XDB_VERSION provide the SQL programmer the ability to perform common tasks on the repository itself. The
methods provided by these packages make it possible to create, delete and rename documents and folders, to move a file or folder within the folder hierarchy, to set and change the access permissions on a file or folder and the ability to initiate and manage versioning.
