Web service data sources use a Teiid specific JCA connector "teiid-connector-ws.rar", which is deployed into the AS7.x during installation. There are many ways to create the file data source, using CLI, AdminShell, admin-console etc. The example shown below uses the CLI tool, as this works in both Standalone and Domain modes.
Execute following command using CLI once you connected to the Server. Make sure you provide the correct endpoint and other properties below. Add any additional properties required by the connector by duplicating the "connection-definitions" command below. Edit the JNDI name to match the JNDI name you used in VDB.
batch
/subsystem=resource-adapters/resource-adapter=wsDS:add(archive=teiid-connector-ws.rar, transaction-support=NoTransaction)
/subsystem=resource-adapters/resource-adapter=wsDS/connection-definitions=wsDS:add(jndi-name=java:/wsDS, class-name=org.teiid.resource.adapter.ws.WSManagedConnectionFactory, enabled=true, use-java-context=true)
/subsystem=resource-adapters/resource-adapter=wsDS/connection-definitions=wsDS/config-properties=EndPoint:add(value={end_point})
/subsystem=resource-adapters/resource-adapter=wsDS/connection-definitions=wsDS:enable
runbatch
To find out all the properties that are supported by this Web Service Connector execute the following command in the CLI.
/subsystem=teiid:read-rar-description(rar-name=teiid-connector-ws.rar)
The Web Service Data Source supports specifying a WSDL using the Wsdl property. If the Wsdl property is set, then the ServiceName, EndPointName, and NamespaceUri properties should also be set. The Wsdl property may be a URL or file location or the WSDL to use.
As of AS 7.1 CR1b release the above does not work without restarting the Server. This issue will be fixed before 7.2 Final.
Developer's Tip
If the JBoss AS 7.x is running in standalone mode, you can also manually edit the "<jboss-install>/standalone/configuration/standalone-teiid.xml" file and add the XML configuration defined in "<jboss-install>/docs/teiid/datasources/web-service" directory under "resource-adapters" subsystem. Shutdown the server before you edit this file, and restart after the modifications are done.
CXF Configuration
Each web service data source may choose a particular CXF config file and port configuration. The ConfigFile config property specifies the Spring XML configuration file for the CXF Bus and port configuration to be used by connections. If no config file is specified then the system default configuration will be used.
Only 1 port configuration can be used by this data source. You may explicitly set the local name of the port QName to use via the ConfigName property. The namespace URI for the QName in your config file should be[http://teiid.org|http://teiid.org]. See the sections on WS-Security, Logging, etc. for examples of using the CXF configuration file.
Sample Spring XML Configuration To Set Timeouts
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
xsi:schemaLocation="http://cxf.apache.org/transports/http/configuration
http://cxf.apache.org/schemas/configuration/http-conf.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<http-conf:conduit name="{http://teiid.org}configName.http-conduit">
<http-conf:client ConnectionTimeout="120000" ReceiveTimeout="240000"/>
</http-conf:conduit>
</beans>
In the conduit name {[http://teiid.org|http://teiid.org]}configName.http-conduit, the namespace, [http://teiid.org|http://teiid.org], is not configurable. The local name is followed by .http-conduit. It will be based upon the configName setting, with a default value of teiid.
See the [CXF documentation|http://cxf.apache.org/docs/] for all possible configuration options.
The CXF configuration is currently only applicable to non-binary web service calls.
Security
To enable the use of WS-Security, the SecurityType should be set to WSSecurity. At this time Teiid does not expect a WSDL to describe the service being used. Thus a Spring XML configuration file is not only required, it must instead contain all of the relevant policy configuration. And just as with the general configuration, each data source is limited to specifying only a single port configuration to use.

Note that the client port configuration is matched to the data source instance by the QName {[http://teiid.org|http://teiid.org]}port_x. The configuration may contain other port configurations with different local names.
For more information on configuring CXF interceptors, please consult the CXF documentation or the JBossWS-CXF documentation.
Logging
The CXF config property may also be used to control the logging of requests and responses for specific or all ports. Logging, when enabled, will be performed at an INFO level to the org.apache.cxf.interceptor context.

Transport Settings
The CXF config property may also be used to control low level aspects of the HTTP transport. See the CXF documentation for all possible options.
