  • Step 6

    Create a File Project for the .properties file that you’re going to upload.

  • Step 7

    Enter the following details about your file translation project:

    Field Name Value
    Project Name espmcloud
    File Type Java Properties File
    Domain Sales
    Source Language English
    Target Languages Enter the languages of your choice, such as French and Italian

    Choose Proceed to upload file(s).

    Create project
  • Step 8

    You can upload the properties file in two ways: there’s the drag & drop option, which automatically starts the translation process, and there’s the more traditional file selection option, which requires you to select the file and start the translation process. The end result is the same, it’s just a matter of how you prefer to work.

    Drag & Drop Option

    Simply drag the file from your Eclipse project to the translation project screen. SAP Translation Hub uploads your properties file to the translation project.

    File Selection Option

    1. On the translation project screen, choose Upload File:
    2. Navigate to the folder on your local PC that contains the file and open it:
      Select properties file

    3. Choose Upload:
      Select properties file

    Regardless of the option you choose, you need to start the translation step by selecting Translate without Download or Translate and Download:

    Start translation
  • Step 9

    To review the translated texts, choose the Translations tab.
    On this screen, you can switch between target languages and view information about the translation provider and quality rating:

    Choose translations tab
  • Step 10

    To better plan the language review process, you can filter translations by the quality rating. For example, this enables you to see only those translations that have a quality rating below a certain threshold, such as 50.
    Choose the filter icon above the Quality Index column:

    Choose filter button

    Choose Quality Index:

    Choose quality index button

    Enter 50 as the upper limit or move the right slider bubble to the center of the scale:

    If you want to update any translations, make the changes in the Translated Text column and choose Save Changes:

    Save translation project
  • Step 12

    Now it’s time to download your translations so that you see your Java app in other languages. Choose Download Translations:

    Download translations

    SAP Translation Hub prepares a zip file that contains properties files for each of the target languages in your translation project; save the zip file on your local PC and make a note of its location. You’ll need to navigate to this file later in the tutorial.

    Confirm zip download
  • Step 13

    Now it’s time to head back to your Eclipse window and import the translations into the project for your Java app.

    Ensure that you’re looking at the Java perspective:

    The properties files per target language appear in the i18n folder:

    Choose Servers tab

    Right-click Java Web Server and choose Clean…:

    Choose Servers tab

    Confirm the clean process by choosing OK:

  • Step 15

    To see your app in the translated languages, enter the following address in a browser; the last two letters denote the language of your app: http://localhost:8080/espm-cloud-web/webshop/?sap-language=fr
