Class WSDLHelper

java.lang.Object
  extended byorg.apache.jmeter.protocol.http.util.WSDLHelper

public class WSDLHelper
extends Object

For now I use DOM for WSDLHelper, but it would be more efficient to use JAXB to generate an object model for WSDL and use it to perform serialization and deserialization. It also makes it easier to traverse the WSDL to get necessary information.

Field Detail

WSDLURL

protected URL WSDLURL
-------------------------------------------- The members used by the class to do its work --------------------------------------------


CONN

protected HttpURLConnection CONN

WSDLDOC

protected org.w3c.dom.Document WSDLDOC

SOAPBINDING

protected String SOAPBINDING

BINDNAME

public String BINDNAME

SOAPOPS

protected Object[] SOAPOPS

ACTIONS

protected HashMap ACTIONS
Constructor Detail

WSDLHelper

public WSDLHelper(String url)
           throws MalformedURLException
Default constructor takes a string URL

Method Detail

getURL

public URL getURL()
Returns the URL

Returns:
the URL

getBinding

public String getBinding()
Returns the binding point for the webservice. Right now it naively assumes there's only one binding point with numerous soap operations.

Returns:
String

connect

protected void connect()
                throws IOException
Method is used internally to connect to the URL. It's protected; therefore external classes should use parse to get the resource at the given location.

Throws:
IOException

close

protected void close()
We try to close the connection to make sure it doesn't hang around.


buildDocument

protected void buildDocument()
                      throws javax.xml.parsers.ParserConfigurationException,
                             IOException,
                             org.xml.sax.SAXException
Method is used internally to parse the InputStream and build the document using javax.xml.parser API.

Throws:
javax.xml.parsers.ParserConfigurationException
IOException
org.xml.sax.SAXException

parse

public void parse()
           throws WSDLException
Call this method to retrieve the WSDL. This method must be called, otherwise a connection to the URL won't be made and the stream won't be parsed.

Throws:
WSDLException

getWebMethods

public String[] getWebMethods()
Get a list of the web methods as a string array.


getSoapAction

public String getSoapAction(String key)
Return the soap action matching the operation name.


getWSDLDocument

public org.w3c.dom.Document getWSDLDocument()
Get the wsdl document.


getSOAPBindings

public Object[] getSOAPBindings()
Method will look at the binding nodes and see if the first child is a soap:binding. If it is, it adds it to an array.

Returns:
Node[]

getOperations

public Object[] getOperations()
Look at the bindings with soap operations and get the soap operations. Since WSDL may describe multiple bindings and each binding may have multiple soap operations, we iterate through the binding nodes with a first child that is a soap binding. If a WSDL doesn't use the same formatting convention, it is possible we may not get a list of all the soap operations. If that is the case, getSOAPBindings() will need to be changed. I should double check the WSDL spec to see what the official requirement is. Another option is to get all operation nodes and check to see if the first child is a soap:operation. The benefit of not getting all operation nodes is WSDL could contain duplicate operations that are not SOAP methods. If there are a large number of methods and half of them are HTTP operations, getting all operations could slow things down.

Returns:
Node[]

main

public static void main(String[] args)
Simple test for the class uses bidbuy.wsdl from Apache's soap driver examples.

Parameters:
args -
