Constructor Detail

SOAPParser

public SOAPParser()

Creates SOAPParser.

Method Detail

initOutput

public void initOutput()
                throws java.lang.Exception

Initializes the output Document

Overrides:

initOutput in class XMLParser

Throws:

java.lang.Exception - If could not find output stream.

parseRequest

public Entry parseRequest(java.lang.Object request)
                   throws java.lang.Exception

Sets the current input stream and initializes the parser.

Parameters:

request - the requested Reader.

Returns:

first read entry containing the parsed attributes.

Throws:

java.lang.Exception - if I/O error occurs.

findNamedElement

public org.w3c.dom.Node findNamedElement(org.w3c.dom.NodeList list,
                                         java.lang.String name)

Finds node element by given name.

Parameters:

list - NodeList to search into.

name - the name of the searched node.

Returns:

first Element node named name.

getElementList

public java.util.Vector<org.w3c.dom.Element> getElementList(org.w3c.dom.Node parent)

Return list containing all children of the parent node.

Parameters:

parent - the parent Node.

Returns:

Vector with all Element children

getElement

public org.w3c.dom.Node getElement(org.w3c.dom.Node parent,
                                   int index)

Returns Node object by given index.

Parameters:

parent - the parent Node.

index - the index of the desired Node.

Returns:

Node object at index position.

getFirstText

public org.w3c.dom.Node getFirstText(org.w3c.dom.Node parent)

Gets the text of the first child of a given Node.

Parameters:

parent - the parent Node

Returns:

string containing the text value.

dumpNodes

public void dumpNodes(java.lang.String prefix,
                      org.w3c.dom.NodeList list)

Prints the contents of the NodeList depending on the types of the .

Parameters:

prefix - prefix of the log message.

list - the NodeList object to be printed.

See Also:

printNode(String, Node)

printNode

public void printNode(java.lang.String prefix,
                      org.w3c.dom.Node n)

Prints the contents of the Node depending on its type.

Parameters:

prefix - prefix of the log message.

n - the Node to be printed.

p

public void p(java.lang.String s)

Writes a message to the log.

Parameters:

s - The log message

See Also:

ParserImpl.logmsg(String)

readEntry

public Entry readEntry()
                throws java.lang.Exception

Reads SOAP XML documents. The attribute SOAP_CALL is set to reflect the first tag following the SOAP-ENV:Body tag. Each tag under the SOAP_CALL tag translates to an attribute in the entry object.

Specified by:

readEntry in interface ParserInterface

Overrides:

readEntry in class XMLParser

Returns:

the entry containing the read attributes.

Throws:

java.lang.Exception - if the XML file is invalid or malformed SOAP XML document.

public org.w3c.dom.Node findBodyElement()

Finds the SOAP Body element.

Returns:

The SOAP Body element

writeEntry

public void writeEntry(Entry entry)
                throws java.lang.Exception

Writes SOAP XML document. The SOAPParser uses attributes from the entry to build the document. The SOAP_CALL attribute is expected to contain the value for the SOAP call. For all others attribute in the entry, a tag with that name and value is created.

Specified by:

writeEntry in interface ParserInterface

Overrides:

writeEntry in class XMLParser

Parameters:

entry - the entry containing the attributes to write.

Throws:

java.lang.Exception - if could not build the DOM tree or serialize the DOM element.

See Also:

DOMException
