Description This method initializes the API. The parameters specify the default locale, and which version of the API your application should bind with (see the Notes below for more details).
You must call this method before calling any of the other methods in the API.
public static void initializeWithLocale(
) throws UWIException;
Table 1. Method parameters
|progName||String||The name of the application calling initializeWithLocale. This name is used to identify the application within the PureEdgeAPI.ini file. It also sets the name that is returned by the XFDL applicationName function.|
|progVer||String||The version and build number of the application calling initializeWithLocale. If the PureEdgeAPI.ini file has an entry for this version of the application, the application will bind to the version of the API listed in that entry.|
|apiVer||String||The version number of the API the application should use by default. If the PureEdgeAPI.ini file does not contain an entry for the specific application, the application will bind to the API specified by this parameter.|
|theLocale||String||The default locale of the application.|
Returns Nothing if call is successful or throws a generic exception (UWIException) if an error occurs.

About binding your applications to the API:
When you initialize the API, the initializeWithLocale method determines which version of the API to use based on the parameters you pass it. This allows you to exercise a great deal of control over which version of the API is used by your applications, and prevents the problems normally associated with common DLL files (often referred to as “DLL hell”).
initializeWithLocale uses a configuration file to determine which version of the API will bind to any application. This allows multiple versions of the API to co-exist on your computer, and ensures that your applications use the correct version of the API.
The configuration file is called PureEdgeAPI.ini and is installed with the API.
Note: You should redistribute the PureEdgeAPI.ini file with any applications that use the API. See Developing and distributing applications API 4 Java.
The configuration file contains a section for each application that might call the API, plus a default “API” section. Each section contains a list of version numbers in the following format:
DTK.initializeWithLocale("progName", "progVer", "apiVer", "theLocale")
For example, the configuration file on a Windows® system might look like this:
<version of application> = <path to API>
The above example contains the default [API] section and a section for the formSample application. The asterisk acts as a wildcard. In the example, 7.6.* corresponds to 7.6.0, 7.6.1, and so on.
The initialize method checks the configuration file to see if your application is listed. For example, using the configuration example above, if you make an initialization call as follows:
7.7.* = C:\Program Files\IBM\Forms Server\4.0\API\redist\msc32\PureEdge\76
7.5.* = C:\Program Files\IBM\Forms Server\4.0\API\redist\msc32\PureEdge\75
1.1.0 = C:\Program Files\IBM\Forms Server\4.0\API\redist\msc32\PureEdge\76
1.0.0 = C:\Program Files\IBM\Forms Server\4.0\API\redist\msc32\PureEdge\75
the application binds to the API in C:\Program Files\IBM\Forms Server\4.0\API\redist\msc32\PureEdge\76 because the entry for version 1.1.0 in the formSample section points to C:\Program Files\IBM\Forms Server\4.0\API\redist\msc32\PureEdge\76.
If your application is not listed in the configuration file, the initialization call uses the version of the API in the apiVer parameter. For example, if you make an initialization call as follows:
DTK.initialize("formSample", "1.1.0", "7.7.0")
the application binds to the API in the [API] section that corresponds to 7.6.0 because there is no entry for version 2.0.0 in the formSample section.
You can add your own entries to the configuration file before distributing it to your customers, or you can rely on the default API entries.
DTK.initialize("formSample", "2.0.0", "7.6.0")
Example In the example below, initializeWithLocale initializes the API for the application called formSample.
private static void initialize( ) throws UWIException
DTK.initializeWithLocale("formSample", "1.0.0", "5.1.0", "fr-FR");
