DJF - Desktop Java Forms
You can see almost all examples of forms definition, data bindings and assistances in demo applications.
After downloading you can run this demo: java -jar djf-demo-1.2-standalone.jar
Main features of Desktop Java Forms:
- Easy CRUD operations.
- View relationships between parent and multiple types of children. There can be various combinations, for example:
- master table and its detail table(s);
- master table and its nested detail table(s);
- master table and its several detail fields with table(s);
- several master tables and their detail table(s); - Reusing components, such as forms, panels and beans.
- Each form has zero to n models and one control panel with following buttons: add record, refresh form, delete record, save, exit form.
- Each form invokes another form (there is no limit).
- Moving between UI-items without mouse (like in DOS forms) by using tab button, up-down arrows (with CTRL combination for text panels)
- Adaptive column display in the grid depending on the resolution.
- Shows wait panel during execution of long operations.
- Supports the following widgets: table, tgrid (tree based on table), combobox and parent-child (linked) combobox, label, text, int, long, num, short, byte, date, textarea, checkbox, period, password, file, phone.
- Supports user activity log.

DbfEngine Java API
Also API allows read memory files (.mem) of Foxpro. Samples for both operations you may see at DbfEngine javadoc.
This API is pure lightweight library without memory consumption and any third party libraries (there are no java loggers and etc.)
The DBF Java API is intended as engine for data exchange purposes.
Features
Engine is very small and fast.
API for reading is made as iterator, API for writing is made in manner as JDBC statement. It is allows to write compact Java code. See code samples below.
Also you can look inside your dbf file by invoking it through command line:
java -jar dbfEngine-1.12.jar your.dbf
The result of parsing dbf header and content will be placed into textual file.
Limitations
This version was tested under MS Foxpro 2.6 without memo field support.
Requirements
DbfEngine requires JDK 1.6 or higher.
Licensing
DbfEngine is issued on under the GNU Lesser General Public License. For further information click here.
Download
You may download DbfEngine 1.12 (2021-APR-25) version binary code here. The source cpde you may get in GitHub repository.

API представляет собой легковесную библиотеку без использования сторонних библиотек. Библиотека предназначена для решения задач обмена данными. В частности ее использует РКЦ флекс для чтения реестров платежей из банков и для выгрузки данных в сторону организаций.
Особенности
API очень компактная и быстрая в работе.
В части чтения данных API выполнена как традиционный итератор, в части записи данных API выполнена как jdbc Statement. Все это позволяет писать компактный код. Смотрите примеры ниже.
Также при помощи этой библиотеки вы можете "заглянуть" внутрь вашего dbf файла через вызов командной строки:
java -jar dbfEngine-1.12.jar your.dbf
Результат разбора шапки dbf файла и содержимого будет помещен в выходной текстовый файл.
Ограничения
Данная версия библиотеки проверена на dbf файлах MS Foxpro 2.6 без поддержки memo.
Требования
DbfEngine для своей работы требует JDK 1.6 или выше.
Лицензирование
API выпущена под лицензией LGPL.
Загрузка
Вы можете скачать бинарную библиотеку версии 1.12 (2021-04-25) здесь, исходный код доступен в GitHub репозитории.
