SOAPFault (Java EE 5 SDK)

javax.xml.soap Interface SOAPFault

所有父接口:

Element, Node, SOAPBodyElement, SOAPElement

public interface SOAPFault

extends SOAPBodyElement

An element in the SOAPBody object that contains error and/or status information. This information may relate to errors in the SOAPMessage object or to problems that are not related to the content in the message itself. Problems not related to the message itself are generally errors in processing, such as the inability to communicate with an upstream server.

Depending on the protocol specified while creating the MessageFactory instance, a SOAPFault has sub-elements as defined in the SOAP 1.1/SOAP 1.2 specification.

setFaultCode

void setFaultCode(Name faultCodeQName)
                  throws SOAPException

Sets this SOAPFault object with the given fault code.

Fault codes, which give information about the fault, are defined in the SOAP 1.1 specification. A fault code is mandatory and must be of type Name. This method provides a convenient way to set a fault code. For example,

 SOAPEnvelope se = ...;
 // Create a qualified name in the SOAP namespace with a localName
 // of "Client". Note that prefix parameter is optional and is null
 // here which causes the implementation to use an appropriate prefix.
 Name qname = se.createName("Client", null,
                            SOAPConstants.URI_NS_SOAP_ENVELOPE);
 SOAPFault fault = ...;
 fault.setFaultCode(qname);
 

It is preferable to use this method over setFaultCode(String).

参数:

faultCodeQName - a Name object giving the fault code to be set. It must be namespace qualified.

抛出异常:

SOAPException - if there was an error in adding the faultcode element to the underlying XML tree.

SAAJ 1.2

getFaultCodeAsName()

setFaultCode

void setFaultCode(QName faultCodeQName)
                  throws SOAPException

Sets this SOAPFault object with the given fault code. It is preferable to use this method over setFaultCode(Name).

参数:

faultCodeQName - a QName object giving the fault code to be set. It must be namespace qualified.

抛出异常:

SOAPException - if there was an error in adding the faultcode element to the underlying XML tree.

从以下版本开始:

SAAJ 1.3

getFaultCodeAsQName(), setFaultCode(Name), getFaultCodeAsQName()

setFaultCode

void setFaultCode(String faultCode)
                  throws SOAPException

Sets this SOAPFault object with the give fault code.

Fault codes, which given information about the fault, are defined in the SOAP 1.1 specification. This element is mandatory in SOAP 1.1. Because the fault code is required to be a QName it is preferable to use the setFaultCode(Name) form of this method.

参数:

faultCode - a String giving the fault code to be set. It must be of the form "prefix:localName" where the prefix has been defined in a namespace declaration.

抛出异常:

SOAPException - if there was an error in adding the faultCode to the underlying XML tree.

getFaultCodeAsName

Name getFaultCodeAsName()

Gets the mandatory SOAP 1.1 fault code for this SOAPFault object as a SAAJ Name object. The SOAP 1.1 specification requires the value of the "faultcode" element to be of type QName. This method returns the content of the element as a QName in the form of a SAAJ Name object. This method should be used instead of the getFaultCode method since it allows applications to easily access the namespace name without additional parsing.

返回:

a Name representing the faultcode

从以下版本开始:

SAAJ 1.2

另请参见:

setFaultCode(Name)

getFaultCodeAsQName

QName getFaultCodeAsQName()

Gets the fault code for this SOAPFault object as a QName object.

返回:

a QName representing the faultcode

从以下版本开始:

SAAJ 1.3

另请参见:

getFaultSubcodes

Iterator getFaultSubcodes()

Gets the Subcodes for this SOAPFault as an iterator over QNames.

返回:

an Iterator that accesses a sequence of QNames. This Iterator should not support the optional remove method. The order in which the Subcodes are returned reflects the hierarchy of Subcodes present in the fault from top to bottom.

抛出异常:

UnsupportedOperationException - if this message does not support the SOAP 1.2 concept of Subcode.

从以下版本开始:

SAAJ 1.3

removeAllFaultSubcodes

void removeAllFaultSubcodes()

Removes any Subcodes that may be contained by this SOAPFault. Subsequent calls to getFaultSubcodes will return an empty iterator until a call to appendFaultSubcode is made.

抛出异常:

UnsupportedOperationException - if this message does not support the SOAP 1.2 concept of Subcode.

从以下版本开始:

SAAJ 1.3

appendFaultSubcode

void appendFaultSubcode(QName subcode)
                        throws SOAPException

Adds a Subcode to the end of the sequence of Subcodes contained by this SOAPFault. Subcodes, which were introduced in SOAP 1.2, are represented by a recursive sequence of subelements rooted in the mandatory Code subelement of a SOAP Fault.

参数:

subcode - a QName containing the Value of the Subcode.

抛出异常:

SOAPException - if there was an error in setting the Subcode

UnsupportedOperationException - if this message does not support the SOAP 1.2 concept of Subcode.
