2 -When setting up a point at which your customers can talk to you, eMagiz offers various methods of creating such a point. One of those options is to host a SOAP Webservice in eMagiz that handles XML messages asynchronously or synchronously. In this microlearning, we will zoom in on the part that validation of the messages plays when offering such a SOAP web service.
2 +n some cases, the input you receive or the output that you need to send to an external party cannot handle all characters or the input or output is written with the help of a character set. In this microlearning, we will learn how you can define the character set for file-based connectivity to ensure that you can process and deliver files according to the specifications.

9 9  == 2. Key concepts ==
10 -This microlearning centers around configuring your SOAP web service.
11 11  
12 -By configuring, we mean: Designing and determining the characteristics of the SOAP web service.
15 +This microlearning centers around learning how to define the character set to ensure that eMagiz processes the information correctly.
13 13  
14 -Crucial parts in the configuration are:
15 -* Operation Name
16 -* SOAP Webservice Namespace
17 -* Validation
18 -* Authentication
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.
19 19  
20 -Of these four points, we will zoom in on the validation part of our SOAP Webservice in this microlearning.
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)

26 -Crucial parts in the configuration are:
27 -* Operation Name
28 -* SOAP Webservice Namespace
29 -* Validation
30 -* Authentication
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:

32 -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 proper credentials (security) and the correct answers (validation) can enter and perform their actions. In the previous microlearning, we talked about the security part. In this microlearning, we talk about the validation part.

30 +- Flat file to XML transformer
31 +- File outbound channel adapter

34 -=== 3.1 Configuration on system message level in Design ===
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.
35 35  
36 -As you have learned from the crash course, you can validate an XML message with the help of an XSD. This XSD describes data types, order, associations, and length of attributes. You can use such an XSD to validate what your clients send you. eMagiz will automatically define a WSDL based on the combination of system messages you provide for each operation you want to host. To ensure that the WSDL is created correctly, don't forget to add an entity called "Send{givenname}Request" to the (request) system message and an entity called "Send{givenname}Response" in case you have a response system message. An example of how this needs to be configured in Design is shown below.

38 -[[image:Main.Images.Microlearning.WebHome@novice-soap-webservice-connectivity-validate-incoming-messages-gen3--root-entity-for-wsdl.png]]
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.

40 -=== 3.2 Effect in Create ===
39 +Congratulations you have successfully learned how to specify the character set.
41 41  
42 -In the infra flow, eMagiz automatically adds a support object of the "Dynamic WSDL" type. In this support object, the link is made between the system message definitions and the WSDL that will be created based on this.

46 -{{warning}}Note that when you make changes to the system message after the integration is already in Create, or when you add a new integration to Create, you need to create a new version of your infra flow to be able to deploy the changes to your WSDL.{{/warning}}
47 -
48 -In this same support object, you also see the default location of the hosted SOAP endpoint, which is http://localhost:${entry.connector.ws.port}/ws/{soap WS name}/. Based on this, you can find the WSDL by adding {soap WS name}.wsdl to the URI. In this example, when hosting the SOAP web service on-premise, a valid URI would be "http://localhost:8099/ws/soapgn3-connector/soapgn3-connector.wsdl".
49 -
50 -{{info}}Note that when running your web service in the eMagiz cloud, the first part (the host part) will change depending on your configuration in Deploy Architecture and the cloud slot on which you are running. An example URI, in that case, would be "https://soap-test-cloud0000.emagizcloud.com/ws/soapgn3-connector/soapgn3-connector.wsdl"{{/info}}

52 -With this done, you have successfully added validation to your SOAP web service.

69 -** Do not forget to add the correct root entity to your system message to make the WSDL work
48 +* Some external system talk in a different character set
49 +* eMagiz talks in default UTF-8 as a character set and assumes everyone else also does this
50 +* In cases of mismatch correct is at the point where you talk with the other system (i.e. entry or exit)
51 +* eMagiz provides several components within which you can define the character set
