This chapter describes internationalization issues to consider when developing an integrated Excel workbook, how to use resource bundles, and how to localize the integrated Excel workbook.
This chapter includes the following sections:
ADF Desktop Integration provides several features that allow you to deliver integrated Excel workbooks as part of an internationalized Fusion web application. One of the principal features is the use of resource bundles to manage the localization of user-visible strings that appear in Oracle ADF components at design time. It also uses resource bundles to manage the user-visible strings that appear in these components at runtime. This chapter also describes the use of resource bundles.
Note the following points about internationalization and localization in an integrated Excel workbook:
ADF Desktop Integration supports both single- and double-byte character sets. It marshals data transmitted between an Excel worksheet and a Fusion web application into XML payloads. These XML payloads use UTF-8 encoding with dates, times, and numbers in canonical formats.
The locale of the system where the Excel workbook is used determines the format for dates, times, and numbers. These settings (formats and the locale of the system) may differ from the settings used by the Fusion web application. ADF Desktop Integration does not attempt to synchronize these settings, but it ensures that the data retains its integrity. ADF Desktop Integration does not provide a mechanism for end users to change the language or display settings of the Oracle ADF components in an integrated Excel workbook at runtime.
When configuring or applying styles to ADF components in an integrated Excel workbook, configure or choose styles that are locale-sensitive. For more information, see Section 9.2, "Working with Styles."
For more information about internationalizing Fusion web applications, see the "Internationalizing and Localizing Pages" chapter in the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework.
You can create integrated Excel workbooks for your internationalized Fusion web application. Designing your integrated Excel workbook as part of the internationalized Fusion web application helps in its easy adaptation to specific local languages and cultures. Using resource bundles and other components, you can configure your integrated Excel workbook for a specific local language or culture by translating text and adding locale-specific components at design time, and also at runtime. For more information, see Section 10.3, "Localization in ADF Desktop Integration."
Figure 10-1 shows an example of an integrated Excel workbook configured for the Japanese language.
ADF Desktop Integration uses resource bundles to manage user-visible strings that appear in the ADF components of an integrated Excel workbook at design time and runtime. JDeveloper stores resource bundles in the ADF Desktop Integration project.
You can register up to twenty resource bundles containing string values you define with an integrated Excel workbook. A resource bundle must not exceed 1 megabyte. If you attempt to register more than twenty resource bundles or a resource bundle that exceeds 1 megabyte, ADF Desktop Integration writes a warning to the client-side log file and stops registration of additional resource bundles or resource bundle data after the 1 megabyte limit is reached.
For example, if resource bundle A measures 2 megabyte and resource bundle B measures 1 megabyte, ADF Desktop Integration registers the first megabyte of data in resource bundle A and all of the data in resource bundle B. For information about client-side logging, see Section C.3.2, "About Client-Side Logging."
Resources workbook property specifies what resource bundles an integrated Excel workbook can use. This property specifies an array of resource bundles (
Resources list) in the integrated Excel workbook. Each element in the array has a property that uniquely identifies a resource bundle (
Alias) and a property that identifies the path to the resource bundle in the JDeveloper desktop integration project (
Class). For example,
EditCustomers-DT.xlsx in the Summit sample application for ADF Desktop Integration references the
res resource bundle that has the following value for the
More information about the
Resources workbook property can be found in Section A.12, "Workbook Actions and Properties."
By default, ADF Desktop Integration provides a reserved resource bundle that supplies string key values used by many component properties at runtime. When you enable an Excel workbook to integrate it with a Fusion web application, the reserved resource bundle is registered by default with the workbook. ADF Desktop Integration uses the value
_ADFDIres to uniquely identify this resource bundle. Many EL expressions reference string values in this resource bundle.
If you register another resource bundle, you can replace default string key values assigned from the
_ADFDIres resource bundle to many of the ADF component properties.
You register a resource bundle by adding an element to the
Resources list using the Edit Resources dialog.
To register a resource bundle:
Open the integrated Excel workbook.
In the Workbook group of the Oracle ADF tab, click Workbook Properties.
In the Edit Workbook Properties dialog, click the browse (...) icon beside the input field for Resources to display the Edit Resources dialog shown in Figure 10-2.
Specify values for the resource bundle and then click OK.
For information about the values to specify for a resource bundle, see the entry for Resources in Table A-18.
While registering a resource bundle class, do not include the file extension.
The overridable resources contains several user-visible runtime strings that you cannot replace by configuring the properties of the ADF Desktop Integration components. Examples include the strings that appear in the default upload dialog illustrated in Figure 7-9.
To replace these user-visible runtime strings, you create a resource bundle in your Fusion web application that contains the string keys from the overridable resource that ADF Desktop Integration supports. Appendix E, "String Keys in the Overridable Resources" lists these string keys. You define values for the string keys listed in Appendix E to override in the resource bundle you create.
To override resources that are not configurable:
Create a resource bundle in your Fusion web application.
For information about creating a resource bundle, see the "Manually Defining Resource Bundles and Locales" section in the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework.
Define the string key values you want to appear at runtime in the resource bundle for the string keys listed in Appendix E, "String Keys in the Overridable Resources."
_ADFDIres as the value of the Alias property when you register the resource bundle you created in Step 1.
For information about how to register a resource bundle, see Section 10.2.1, "How to Register a Resource Bundle in an Integrated Excel Workbook."
Table E-1 describes the string keys in the overridable resources that ADF Desktop Integration supports. Supply an alternative value to the value listed in the English value column for each string key in the overridable resource.
ADF Desktop Integration retrieves the values of string keys listed in Table E-1 that you defined in the resource bundle you created. It retrieves the values of other string keys that you did not define in the resource bundle you created from the reserved resource bundle.
If you provide override values for
LOGIN_CONFIRM_CONNECT_2, the override values will not appear on the first connection to the web application. The default values will be used on the first connection.
See the following sections for additional information about resource bundles in an integrated Excel workbook.
ADF Desktop Integration supports use of the following types of resource bundle:
Properties bundle (
List resource bundle (
Xliff resource bundle (
For more information about resource bundles, see the "Manually Defining Locales and Resource Bundles" section in the Oracle Fusion Middleware Web User Interface Developer's Guide for Oracle Application Development Framework.
ADF Desktop Integration caches the values of string keys from the resource bundles that an integrated Excel workbook retrieves when it first connects to the Fusion web application. If you change a string key value in a resource bundle after an integrated Excel workbook has cached the previous value, the modified value does not appear in the workbook unless the
ClearAllData workbook action is invoked and the end user closes and reopens the workbook so that it retrieves the modified value from the Fusion web application. For more information about the
ClearAllData workbook action, see Table A-17.
ADF Desktop Integration requires that you enclose the string key name in EL expressions using the
 characters, as in the following example:
Note that ADF Desktop Integration does not support the following syntax:
ADF Desktop Integration integrates several diverse sets of technologies. Each of these technologies provides various options for controlling the choice of natural human language when you localize your Fusion web application.
When the end user interacts with an integrated Excel workbook, various elements are involved. Each of these elements has its own set of supported languages and resource translations. In such a scenario, the translation of language is the responsibility of the respective publisher.
Table 10-1 presents a summary of elements involved and their role in translation:
