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

public 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:

java.lang.IllegalArgumentException - If invalid operation name is specified

addParameter

public void addParameter(java.lang.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.

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

See Also:

isParameterAndReturnSpecRequired(javax.xml.namespace.QName)

addParameter

public void addParameter(java.lang.String paramName,
                         QName xmlType,
                         java.lang.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.

Gets the return type for a specific operation

Returns:

Returns the XML type for the return value
