Client Toolkit Examples

This table below contains links to each of the examples covered in the Client Toolkit Tutorial. For more details please refer to the tutorial. For comprehensive documentation of the Client Toolkit APIs please refer to the OGSA-DAI Javadoc.

Example	Description
A Simple Example
Simple Example	Runs a simple query on a relational data service resource exposed by a data service.
The Basics
Locating A Data Service	Contacts a data service and gets the list of resources exposed by the data service.
Performing Queries
Simple SQL Query	Submits a simple SQL query.
Sequence of SQL Queries	Submits a request containing several queries.
Parameterised SQL Query	Parameterises an SQL query then submits it repeatedly with different parameter values.
Simple XPath Query	Submits a simple XPath query against an XMLDB collection.
Processing Results
Processing SQL Query Results	Processes the results of an SQL query using the JDBC `java.sql.ResultSet` interface.
Processing Larger SQL Query Result Sets	Process the results of an SQL query that returns a large number of rows. The rows are returned asynchronously from the service via the use of a DTOutputStream so that the entire results do not have to be returned to the client in one go.
Processing XPath Query Results	Processes the results of an XPath query using the XMLDB org.xmldb.api.base.ResourceSet interface.
Updates and Bulk Load
SQL Update	Performs an SQL update. A new row is inserted, updated and then deleted.
SQL Bulk Load	Bulk loads the results of a query performed against one table into another table.
SQL Update Parameterised Via Data Transport	Performs a parameterised SQL update, the parameter values being provided via the service's putBlock data transport operation.
XUpdate	Performs an XUpdate statement.
Transforming Data
XSL Transform With Delivery	Transforms the results of an SQL query into an HTML table. The XSL Transform document is loaded from a URL.
Using Sessions
Using Sessions	A session is created, a request joins the session, the session is terminated.
Asynchronous Requests
Aysnchronous Requests	Introduces asynchronous requests and explains how to monitor the status of a request.
Asynchronous Delivery
Data Transport Example	One service pulls data to another service via the use of the getBlock data transport operation.
Data Integration
Data Integration Example	A simple data integration scenario. An XPath query is performed on an XML database, the results are transformed into a WebRowSet and bulk loaded into a temporary table on a relational database.
Using Message-Level andTransport-Level Security (OGSA-DAI WSRF only)
Using Transport Level Security	Using transport-level security when communicating with a service.
Using Message Level Security	Using message-level security when communicating with a service.
