When you are generating a VGWebTransaction program, a VGUI record, or a DataTable (type msgTable), the build descriptor option genResourceBundle specifies whether to generate a Java™ resource bundle, which is a Java object that contains strings to be presented at runtime. The content of a resource bundle generated for a VGUI record includes the Web-page title, labels, and help text; and the content of a resource bundle generated for a message table includes a set of messages.
When you are generating a VGWebTransaction program and have specified a value for the program property msgTablePrefix, EGL produces a message resource bundle regardless of the value of genResourceBundle.
If you want to specify a Java locale for the generated resource bundle, set the build descriptor option resourceBundleLocale.
