portlets can be deployed to OracleAS Portal through three
provider types: Web providers, WSRP providers, and database providers. Web
providers are deployed to a J2EE application server, which is often remote and
communicates with OracleAS Portal through Simple Object Access Protocol (SOAP)
over HTTP. Web Services for Remote Portlets (WSRP), an OASIS standard, is
supported in the Developer’s Preview of OracleAS Portal. Database providers are
Data source What you need to know about the data source
Spreadsheet The URL that points to the spreadsheet containing the data that
you want to display in the portlet.
SQL The connection information to the data source and the SQL
query that retrieves the data from the database.
XML The location of the XML source and optionally the address of
the XSL filter and the XML schema.
Web service The WSDL URL, the method of the Web service, and optionally
the XSL filter URL and the XML schema URL.
Web page The Web page data source uses the same environment as Web
Clipping. No technical background is required.
J2EE Connector
Architecture
Although not displayed on the Type page of the OmniPortlet
wizard, a J2EEtm Connector Architecture (JCA) 1.0 adapter is
also available. JCA provides a mechanism to store and retrieve
enterprise data such as that held in ERP systems (Oracle
Financials, SAP, PeopleSoft, and so on).
