Create SOAP Request with Java

The Membrane SOA Model can create SOAP requests out of a WSDL document and a Java Map filled with the data for the request.

Listing 1: CreateSOAPRequest

The following table shows the input for the SOARequestCreator.

Key	Value
xpath:/create/article/name	foo
xpath:/create/article/description	bar
xpath:/create/article/price/amount	00.00
xpath:/create/article/price/currency	USD
xpath:/create/article/id	1

Using the table above you get the following soap request message.

01.<s11:Envelope xmlns:s11='http://schemas.xmlsoap.org/soap/envelope/'>

02.<s11:Body>

03.<ns1:create xmlns:ns1='http://predic8.com/wsdl/material/ArticleService/1/'>

04.<article xmlns:ns1='http://predic8.com/material/1/'>

05.<name xmlns:ns1='http://predic8.com/material/1/'>foo</name>

06.<description xmlns:ns1='http://predic8.com/material/1/'>bar</description>

07.<price xmlns:ns1='http://predic8.com/common/1/'>

08.<amount xmlns:ns1='http://predic8.com/common/1/'>00.00</amount>

09.<currency xmlns:ns1='http://predic8.com/common/1/'>USD</currency>

10.</price>

11.<id xmlns:ns1='http://predic8.com/material/1/'>1</id>

12.</article>

13.</ns1:create>

14.</s11:Body>

15.</s11:Envelope>

Unbounded Elements

To create a list of repeating elements in a SOAP request square brackets can be used.
Listing 3 shows how to set the formParams from Listing 1 to create a request with more than one item.

01....

02.HashMap<String, String> formParams = new HashMap<String, String>();

03.formParams.put("xpath:/order/items/item[1]/name", "apple");

04.formParams.put("xpath:/order/items/item[1]/quantity", "3");

05.formParams.put("xpath:/order/items/item[1]/price", ".95");

06.formParams.put("xpath:/order/items/item[2]/name", "orange");

07.formParams.put("xpath:/order/items/item[2]/quantity", "5");

08.formParams.put("xpath:/order/items/item[2]/price", "1.45");
