Java XML client from xsd

true_atlantis · 09-13-2007, 10:11 AM

So, I am pretty new to XML in general, and am confused about the whole style sheet concept. First, I have been using 'org.apache.xmlrpc.client.XmlRpcClient' to send XML requests, but have been given specific XML functions with the arguments that the XML functions are expecting. Now, all I have are many XML style sheets and am trying to get a feel for how to understand the format of the xsd. For example, I have:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
	<xs:include schemaLocation="archer.xsd"/>
	<xs:element name="CreateNDTicket">
		<xs:complexType>
			<xs:sequence>
				<xs:element name="Request">
					<xs:complexType>
						<xs:sequence>
							<xs:element name="RequestHeader" type="RequestHeaderType"/>
							<xs:element name="RequestBody">
								<xs:complexType>
									<xs:sequence>
										<xs:element name="CreateCriteria">
											<xs:complexType>
												<xs:sequence>
													<xs:element name="SystemId" type="xs:string"/>
													<xs:element name="IndicatorCity" type="xs:string"/>
													<xs:element name="IndicatorState" type="xs:string"/>
													<xs:element name="AlarmStart" type="DateTimeType"/>
													<xs:element name="AttributeList" type="AttributeListType"/>
													<xs:element name="ContactInformation" type="ContactInformationType"/>
													<xs:element name="NextAction" type="xs:string" minOccurs="0"/>
													<xs:element name="ProblemCode" type="xs:string"/>
													<xs:element name="Source" type="xs:string"/>
													<xs:element name="SourceReference" type="xs:string"/>
													<xs:element name="ServiceAffected" type="xs:boolean"/>
													<xs:element name="Worklog" type="WorklogType" minOccurs="0"/>
												</xs:sequence>
											</xs:complexType>
										</xs:element>
									</xs:sequence>
								</xs:complexType>
							</xs:element>
						</xs:sequence>
					</xs:complexType>
				</xs:element>
				<xs:element name="Response" minOccurs="0">
					<xs:complexType>
						<xs:sequence>
							<xs:element name="ResponseHeader" type="ResponseHeaderType"/>
							<xs:element name="ResponseBody" minOccurs="0">
								<xs:complexType>
									<xs:sequence>
										<xs:element name="TicketId" type="xs:string"/>
									</xs:sequence>
								</xs:complexType>
							</xs:element>
						</xs:sequence>
					</xs:complexType>
				</xs:element>
			</xs:sequence>
		</xs:complexType>
	</xs:element>
</xs:schema>

Does this mean there is a function called CreateNDTicket that is expecting the arguments SystemId, IndicatorCity, ... , Worklog (variable types defined by xs:string/boolean etc)? Or does it mean there is a function called CreateNDTicket that is expecting an array that starts with 'Request' and contains another array with 'RequestHeader' which contains another array 'RequestBody' etc? Or, am I way off?

I know that types like 'DateTimeType' are defined in the included archer.xsd file.

Thanks.

Hi -

Basically, you're way off.

XML involves a whole, big alphabet soup of different things. XSL and XSLT ("Style sheets") have to do with translating an XML document into something else (for example, into a .pdf or an .html document; or into another, different XML document). That's not what you're doing here.

XSD (XSchema Definition) has to do with defining structured data. Your "CreateNDTicket" is a *record*. It happens to define a SOAP message that you happen to be using in a web service - but it's still "data", not a "function".

It sounds like you're trying to familiarize yourself with Web Services. I'd suggest picking any one API that's convenient (for example, Microsoft C# or ASP.Net, or Java Glassfish - whatever works best for you), start with some simple "hello world" web services, and work your way out from there:
