javax.xml.rpc

Interface Call

public interface Call

The javax.xml.rpc.Call interface provides support for the dynamic invocation of a service endpoint. The javax.xml.rpc.Service interface acts as a factory for the creation of Call instances.

Once a Call instance is created, various setter and getter methods may be used to configure this Call instance.

Method Detail

isParameterAndReturnSpecRequired

boolean isParameterAndReturnSpecRequired(QName operationName)

Indicates whether addParameter and setReturnType methods are to be invoked to specify the parameter and return type specification for a specific operation.

Parameters:

operationName - Qualified name of the operation

Returns:

Returns true if the Call implementation class requires addParameter and setReturnType to be invoked in the client code for the specified operation. This method returns false otherwise.

Throws:

IllegalArgumentException - If invalid operation name is specified

addParameter

void addParameter(String paramName,
                  QName xmlType,
                  ParameterMode parameterMode)

Adds a parameter type and mode for a specific operation. Note that the client code may not call any addParameter and setReturnType methods before calling the invoke method. In this case, the Call implementation class determines the parameter types by using reflection on parameters, using the WSDL description and configured type mapping registry.

Parameters:

paramName - Name of the parameter

xmlType - XML type of the parameter

parameterMode - Mode of the parameter-whether ParameterMode.IN, ParameterMode.OUT, or ParameterMode.INOUT,

Throws:

javax.xml.rpc.JAXRPCException: - This exception may be thrown if the method isParameterAndReturnSpecRequired returns false for this operation.

IllegalArgumentException - If any illegal parameter name or XML type is specified

See Also:

isParameterAndReturnSpecRequired(javax.xml.namespace.QName)

addParameter

void addParameter(String paramName,
                  QName xmlType,
                  Class javaType,
                  ParameterMode parameterMode)

Adds a parameter type and mode for a specific operation. This method is used to specify the Java type for either OUT or INOUT parameters.

Parameters:

paramName - Name of the parameter

xmlType - XML type of the parameter

javaType - Java class of the parameter

parameterMode - Mode of the parameter-whether ParameterMode.IN, OUT or INOUT

Throws:

JAXRPCException -

• This exception may be thrown if this method is invoked when the method isParameterAndReturnSpecRequired returns false.
• If specified XML type and Java type mapping is not valid. For example, TypeMappingRegistry has no serializers for this mapping.

IllegalArgumentException - If any illegal parameter name or XML type is specified

UnsupportedOperationException - If this method is not supported

See Also:

isParameterAndReturnSpecRequired(javax.xml.namespace.QName)

getParameterTypeByName

QName getParameterTypeByName(String paramName)

Gets the XML type of a parameter by name

Parameters:

paramName - Name of the parameter

Returns:

Returns XML type for the specified parameter

setReturnType

void setReturnType(QName xmlType)

Sets the return type for a specific operation. Invoking setReturnType(null) removes the return type for this Call object.

Parameters:

xmlType - XML data type of the return value

Throws:

JAXRPCException - This exception may be thrown when the method isParameterAndReturnSpecRequired returns false.

IllegalArgumentException - If an illegal XML type is specified

setReturnType

void setReturnType(QName xmlType,
                   Class javaType)

Sets the return type for a specific operation.

Parameters:

xmlType - XML data type of the return value

javaType - Java Class of the return value

Throws:

JAXRPCException -

• This exception may be thrown if this method is invoked when the method isParameterAndReturnSpecRequired returns false.
• If XML type and Java type cannot be mapped using the standard type mapping or TypeMapping registry

UnsupportedOperationException - If this method is not supported

IllegalArgumentException - If an illegal XML type is specified

getReturnType

QName getReturnType()

Gets the return type for a specific operation

Returns:

Returns the XML type for the return value

removeAllParameters

void removeAllParameters()

Removes all specified parameters from this Call instance. Note that this method removes only the parameters and not the return type. The setReturnType(null) is used to remove the return type.

Throws:

JAXRPCException - This exception may be thrown If this method is called when the method isParameterAndReturnSpecRequired returns false for this Call's operation.

getOperationName

QName getOperationName()

Gets the name of the operation to be invoked using this Call instance.

Returns:

Qualified name of the operation

setOperationName

void setOperationName(QName operationName)

Sets the name of the operation to be invoked using this Call instance.

Parameters:

value - Value of the property

Throws:

JAXRPCException -

• If an optional standard property name is specified, however this Call implementation class does not support the configuration of this property.

• If there is any error in the configuration of a valid property.

getProperty

Object getProperty(String name)

invokeOneWay

void invokeOneWay(Object[] inputParams)

Returns:

Map Output parameters for the last Call.invoke(). Empty Map is returned if there are no output parameters.

Throws:

JAXRPCException - If this method is invoked for a one-way operation or is invoked before any invoke method has been called.

getOutputValues

List getOutputValues()
