15		-This microlearning centers around learning how to define the character set to ensure that eMagiz processes the information correctly.
	15	+By configuring, we mean: Designing and determining the characteristics of the SOAP web service
16	16
17		-By character set, we mean: The composite number of different characters that are being used and supported by computer software and hardware. It consists of codes, bit patterns, or natural numbers used in defining some particular character.
	17	+Crucial parts in the configuration are:
	18	+* Operation Name
	19	+* SOAP Webservice Namespace
	20	+* Validation
	21	+* Authentication

19		-* Some external system talk in a different character set
20		-* eMagiz talks in default UTF-8 as a character set and assumes everyone else also does this
21		-* In cases of mismatch correct is at the point where you talk with the other system (i.e. entry or exit)
	23	+Of these four points, we will zoom in on the validation part of our SOAP Webservice in this microlearning.

27		-Sometimes external systems only talk in a specific character set. To ensure that all the data is properly communicated between eMagiz and the other system we need to make sure that we define which character set that is so we can tell it to eMagiz via a component. That way eMagiz will deviate from its default (i.e. UTF-8) and will process the file according to that different character set. In practice, we mainly see windows-1252 as an alternative that pops up once in a while. In various components that deal with file handling, you can define the character set on which eMagiz should act. Examples of such components are:
	35	+Of these four points, we will zoom in on the validation part of our SOAP Webservice in this microlearning. The SOAP Webservice serves as a point of entry where people with the rights credentials (security) and the right answers (validation) are allowed to enter and perform their actions. In the next microlearning, we will talk about the security part. In this microlearning, we talk about the validation part.

30		-- Flat file to XML transformer
31		-- File outbound channel adapter
	37	+As you have learned from the crash course you can validate an XML message with the help of an XSD. This XSD describes dataTypes, order, associations, and length of attributes. You can use such an XSD for the validation of what your clients send you. eMagiz will automatically define a WSDL based on the XSD that you provide that stores metainformation and stores the XSD for validation purposes. This way you can communicate the WSDL (location) to external parties as a reference document upon which they can build their solution. If you keep the eMagiz defaults you can access the WSDL via http://host:port/ws/ws-name/ws-name.wsdl. Note that you need to all values (except for the ws and .wsdl part) with actual values.
32	32
33		-In all these components you have the option to define the character set within the Advanced tab of the component. In this microlearning, we will use the File to string transformer to illustrate how that will look.
	39	+What eMagiz does need from you is the correct XSD for validation. As a starting point you should download the XSD that eMagiz has generated based on the system message(s) you have defined in the Design phase. Once you have that you can structure the XSD correctly. A valid XSD start with a schema segment. In this segment you need to define your SOAP WS namespace:

	45	+ targetNamespace="http://www.academy.emagiz.com/ns/mlacade-bus/spwbsrv-connector/1.0/">
36	36
37		-In this field, you can define the character set of your choice. To make this work in eMagiz you need to navigate to the Create phase of eMagiz and open the entry flow in which you want to retrieve the file to a certain location. Within the context of this flow, we need to add functionality that will ensure that the correct character set is used. To do so first enter "Start Editing" mode on flow level. After that open, the File to string transformer, navigate to the Advanced tab, and fill in the correct character set. After you have defined the correct character set the only thing left to do is to Save the component. See the suggested additional readings section on the complete list of character sets that are supported by Java 8.
	47	+Once you have that you need to copy all complex and simple types from the XSD that you downloaded and paste them below the lines you have created:
38	38
39		-Congratulations you have successfully learned how to specify the character set.
	49	+<xs:complexType name="Input">
	50	+ <xs:sequence>
	51	+ <xs:element name="String" type="nonEmptyString"/>
	52	+ <xs:element minOccurs="0" name="Decimal" type="xs:decimal"/>
	53	+ <xs:element name="Enum" type="Enum"/>
	54	+ <xs:element name="Integer" type="xs:long"/>
	55	+ <xs:element name="Boolean" type="xs:boolean"/>
	56	+ <xs:element minOccurs="0" name="DateTime" type="xs:dateTime"/>
	57	+ </xs:sequence>
	58	+ </xs:complexType>
	59	+ <xs:simpleType name="nonEmptyString">
	60	+ <xs:restriction base="xs:string">
	61	+ <xs:minLength value="1"/>
	62	+ </xs:restriction>
	63	+ </xs:simpleType>
	64	+ <xs:simpleType name="Enum">
	65	+ <xs:restriction base="xs:string">
	66	+ <xs:enumeration value="URGENT"/>
	67	+ <xs:enumeration value="HIGH"/>
	68	+ <xs:enumeration value="MEDIUM"/>
	69	+ <xs:enumeration value="LOW"/>
	70	+ <xs:enumeration value="PLANNING"/>
	71	+ </xs:restriction>
	72	+ </xs:simpleType>
40	40
	74	+To wrap things up you need to define your Request and Response element and close the schema:
	75	+
	76	+<xs:element name="SendNptRequest">
	77	+ <xs:complexType>
	78	+ <xs:sequence>
	79	+ <xs:element name="Input" type="Input"/>
	80	+ </xs:sequence>
	81	+ </xs:complexType>
	82	+ </xs:element>
	83	+ <xs:element name="SendNptResponse">
	84	+ <xs:complexType/>
	85	+ </xs:element>
	86	+ </xs:schema>
	87	+
	88	+Combining this will result in a valid XSD for my example. In your case, you will need to enter other values. When you are done with the creation of the XSD save it with a name such as spwbsrv-connector.xsd and upload it to the flow. After you have uploaded the XSD link it to the connector-xsd support object in your entry.

	94	+With this done you have successfully added validation to your SOAP web service.
