To browse CVS via the web use the FishEye interface
For those developers who are stuck behind a corporate firewall, you could try ask your firewall administrator nicely to open up CVS or SSH - or failing that Fisheye can support tarball downloads...
This project's CVS repository can be checked out through anonymous (pserver) CVS with the following instruction set. When prompted for a password for anonymous, simply press the Enter key.
Updates from within the module's directory do not need the -d parameter.
Only project developers can access the CVS tree via this method. SSH1 must be installed on your client machine. Substitute username with the proper value. Enter your site password when prompted.
Remember to replace 'username' with your actual username on cvs.activemq.codehaus.org.
