OpenJPA uses Subversion to manage its source code. Instructions on Subversion use can be found here.

Main repository

Web Access

The source code for OpenJPA can be freely browsed at

Anonymous access

OpenJPA source can be checked out anonymously with this command:

$> svn checkout openjpa

Once you have OpenJPA checked out you can update the source by executing the following command from within the openjpa directory.

$> svn update

Once you've got the code you'll probably want to build it; for instructions see Building OpenJPA.

Access from behind a firewall

For those users who are stuck behind a corporate firewall which is blocking http access to the Subversion repository, you can try to access it via HTTPS:

$> svn checkout openjpa

Access through a proxy

The Subversion client can go through a proxy, if you configure it to do so. First, edit your "servers" configuration file to indicate which proxy to use. The files location depends on your operating system. On Linux or Unix it is located in the directory "~/.subversion". On Windows it is in "%APPDATA%\Subversion". (Try "echo %APPDATA%", note this is a hidden directory.)

There are comments in the file explaining what to do. If you don't have that file, get the latest Subversion client and run any command; this will cause the configuration directory and template files to be created.

Example : Edit the 'servers' file and add something like :

http-proxy-host =
http-proxy-port = 3128

Submitting a Patch

If you make changes to OpenJPA, and would like to contribute the to the project, you should create a patch and post it to the OpenJPA JIRA issue tracker. To create a patch, simply execute the following command:

$> svn diff > your-changes.patch

Developer Access

Everyone can access the OpenJPA Subversion repository via HTTPS, but OpenJPA Committers must checkout the Subversion repository via HTTPS.

$> svn checkout openjpa

To commit changes to the repository, you must set your password on the Apache Subversion server. To set your password, use ssh to connect to, and enter the command svnpasswd. This will prompt you to enter a svn password of your choice (pick a safe password). Now, now your are ready to commit changes using your username/password. Execute the following command to commit your changes (svn will prompt you for your password)

$> svn commit --username your-username
Authentication realm: <> ASF Committers
Password for 'your-username': your-password

You can also pass your password on the command line directly, but this is a security problem on multiuser unix computers (the command line arguments are available via the ps command). Here is the command if you are Windows or a single user unix computer:

$> svn commit --username your-username --password your-password

Remember to replace 'your-username' and 'your-password' with your actual username and password on
