public class WSDefinition
/** Definition of the WebService data control instance.
The webservice data control definitions can be created in following ways
#loadFromMetadata(Node, HashMap)
to load from the metadata definition. Once the definition is loaded,
it calls the createDataControl()
to create the data control
instance.

public WSDefinition()
public WSDefinition(java.net.URL wsdlURL) throws AdapterException
wsdlURL
- The WSDL URL
describing the service.
{@link
- AdapterException} if the data control definition
cannot be created from the WSDL URL
AdapterException
public WSDefinition(java.lang.String name, java.net.URL wsdlURL) throws AdapterException
name
- The name of the data control for which the definition
is being created.wsdlURL
- The URL of the service description.
{@link
- AdapterException} if the definition for this data
control could be created. This failure may happen if the
WSDL url is invalid and the model cannot be initialized.
or the underlying connection cannot be created.
AdapterException
public WSDefinition(java.lang.String name, java.net.URL wsdlURL, WSModel model, javax.xml.namespace.QName serviceName) throws AdapterException
name
- The name of the data control for which the definition
is being created.wsdlURL
- The URL of the service description.model
- The model representing the Service. The model describes
all the ports and operations exposed by the service
description.serviceName
- The qualified service name for which the definition
is to be intialized. The service description may
describe more that one service. In such a case
the definition is created for the requested service.
{@link
- AdapterException} if the definition for this data
control could be created. This failure may happen if the
WSDL url is invalid and the model cannot be initialized.
or the underlying connection cannot be created.

AdapterException
public boolean isStructureDirty(boolean refresh)
refresh
if refresh is requested. If a refresh is needed,
the data control definition recreates the underlying model and connection
to update the metadata of any possible changes to the service operation
signature.
isStructureDirty
in class AbstractDefinition
refresh
- flag to indicate if the refresh is requested for the
structure. If true
, the definition
regenerates the underlying model, operation map and
connection information. This re-generation is needed to
rebuild the structure and make sure that the runtime
has the right connection metadata to execute any modified
operation bindings
true
if the implementation decides that the
structure of the data should be regenerated,
false
otherwise.public Node getMetadata()
The WSDL is parsed to extract as much information as is needed to be stored in the metdata to invoke the service operation at runtime.
getMetadata
in class AbstractDefinition
Node
that defines the metadata for this instance.
This metadata will be used at the runtime to fetch data from the
data source.public java.util.Map getDefaultDCOperations(javax.xml.namespace.QName serviceName) throws AdapterException
serviceName
- The Qualified service Name for which operations
must be fetched.
Map
of Operations for this service.
{@link
- AdapterException} if the service does not exist in
the underlying model.
AdapterException
public void bindServiceConnection(javax.naming.Context context) throws AdapterException
context
- The Context
provided by the caller into which
the connection for this service is to be bound.
{@link
- AdapterException} If the connection cannot be bound into
the context provided.
AdapterException
public boolean isSupported(java.lang.String flag)
AbstractDefinition
isSupported
in class AbstractDefinition
flag
- one of the values defined in
DataControlDefinition
.
public void setRootStructureName(java.lang.String rootDefName)
rootDefName
- The qualified root structure name for this dcpublic java.lang.String getRootStructureName()
protected void destroy() throws AdapterException
Should be invoked by the data control when it is released from an application. The data control definition is voided out once the destroy is invoked. This includes cleaning up of the operations table, purging out the security model and the underlying connection bindings. The definition is not usable anymore once it is destroyed. A new instance of the definition must be created for the dc by loading the definition from the metadata.
AdapterException
- if the definition cannot be destroyed.
