version 1.1.4
DerbyOOo is part of a Suite of LibreOffice and/or OpenOffice extensions allowing to offer you innovative services in these office suites.
This extension allows you to use Apache Derby database in embedded mode, making the database portable (a single odb file).
It allows you to take advantage of the ACID properties of the underlying Apache Derby database.
Being free software I encourage you:
- To duplicate its source code.
- To make changes, corrections, improvements.
- To open issue if needed.
In short, to participate in the development of this extension.
Because it is together that we can make Free Software smarter.
The DerbyOOo extension uses the jdbcDriverOOo extension to work.
It must therefore meet the requirement of the jdbcDriverOOo extension.
Since version 1.1.0, only LibreOffice 24.2.x or higher is supported. If it is not possible for you to use such a version, use the previous version of DerbyOOo. But in this case, this extension cannot be installed with the HyperSQLOOo extension, see bug #156471. In addition, it will be difficult for you to migrate odb files created under lower versions of DerbyOOo. I recommend using LibreOffice 24.2.x minimum with DerbyOOo 1.1.0 or higher.
On Linux and macOS the Python packages used by the extension, if already installed, may come from the system and therefore may not be up to date.
To ensure that your Python packages are up to date it is recommended to use the System Info option in the extension Options accessible by:
Tools -> Options -> Base drivers -> Embedded SQLite Driver -> View log -> System Info
If outdated packages appear, you can update them with the command:
pip install --upgrade <package-name>
It seems important that the file was not renamed when it was downloaded.
If necessary, rename it before installing it.
-
Install jdbcDriverOOo.oxt extension
This extension is necessary to use Apache Derby with all its features.
-
Install DerbyOOo.oxt extension
Restart LibreOffice after installation.
Be careful, restarting LibreOffice may not be enough.
- On Windows to ensure that LibreOffice restarts correctly, use Windows Task Manager to verify that no LibreOffice services are visible after LibreOffice shuts down (and kill it if so).
- Under Linux or macOS you can also ensure that LibreOffice restarts correctly, by launching it from a terminal with the command
sofficeand using the key combinationCtrl + Cif after stopping LibreOffice, the terminal is not active (no command prompt).
In LibreOffice / OpenOffice go to File -> New -> Database...:
In step: Select database:
- select: Create a new database
- in: Emdedded database: choose: Embedded SQLite Driver
- click on button: Next
In step: Save and proceed:
- adjust the parameters according to your needs...
- click on button: Finish
Have fun...
DerbyOOo is an com.sun.star.sdbc.Driver UNO service written in Python.
It is an overlay to the jdbcDriverOOo extension allowing to store the Derby database in an odb file (which is, in fact, a compressed file).
Its operation is quite basic, namely:
- When requesting a connection, several things are done:
- If it does not already exist, a subdirectory with name:
.+odb_file_name+.lckis created in the location of the odb file where all Derby files are extracted from the database directory of the odb file (unzip). - The jdbcDriverOOo extension is used to get the com.sun.star.sdbc.XConnection interface from the subdirectory path +
/Derby. - If the connection is successful, a DocumentHandler is added as an com.sun.star.util.XCloseListener and com.sun.star.document.XStorageChangeListener to the odb file.
- If the connection is unsuccessful and the files was extracted in phase 1, the subdirectory will be deleted.
- If it does not already exist, a subdirectory with name:
- When closing or renaming (Save As) the odb file, if the connection was successful, the DocumentHandler copies all files present in the subdirectory into the (new) database directory of the odb file (zip), then delete the subdirectory.
The main purpose of this mode of operation is to take advantage of the ACID characteristics of the underlying database in the event of an abnormal closure of LibreOffice. On the other hand, the function: file -> Save has no effect on the underlying database. Only closing the odb file or saving it under a different name (File -> Save As) will save the database in the odb file.

I encourage you in case of problem 😕
to create an issue
I will try to solve it 😄
- Implementation of a new format in odb files allowing the name of the catalog of the underlying database to be taken into account.
- This version is based on fix #154989 available since LibreOffice 24.2.x. It can therefore work with other extensions offering integrated database services.
- Now DerbyOOo requires LibreOffice 24.2.x minimum and will load for the url:
sdbc:embedded:derby.
- Updated the Python packaging package to version 24.1.
- Updated the Python setuptools package to version 72.1.0.
- The extension will ask you to install the jdbcDriverOOo extension in versions 1.4.2 minimum.
- Fixed issue #2 which appears to be a regression related to the release of JaybirdOOo. Thanks to TeddyBoomer for reporting it.
- Updated the Python setuptools package to version 73.0.1.
- Logging accessible in extension options now displays correctly on Windows.
- Derby is now properly shutdown before files are recompressed into the odb file (ie: the db.lck file is no longer present in the odb file).
- The extension options are now accessible via: Tools -> Options... -> LibreOffice Base -> Embedded Derby Driver
- Changes to extension options that require a restart of LibreOffice will result in a message being displayed.
- Support for LibreOffice version 24.8.x.
- Requires the latest version of jdbcDriverOOo 1.4.4.
- In the extension options it is possible to define the options: View system tables, Use bookmarks and Force SQL mode which will be specific to this driver.
- The extension will ask you to install jdbcDriverOOo extension in versions 1.4.6 minimum.
- Modification of the extension options accessible via: Tools -> Options... -> LibreOffice Base -> Embedded Derby Driver in order to comply with the new graphic charter.
-
Add new language for internationalization...
-
Anything welcome...
