Like many other open-source projects, the OpenDMK project requires contributors to jointly assign their copyright on contributed code. If you haven't yet signed the Oracle Contributor Agreement (OCA) then please do so scan it and e-mail the result to sun_ca(at)sun.com.
Please make sure to specify your java.net user name, and to specify OpenDMK as the project you'd like to contribute to so that we can process and store your OCA.
The OCA gives Oracle and the contributor joint copyright interests in the code. The contributor retains copyrights while also granting those rights to Oracle as the Community's sponsor. You only need to sign the OCA once in order to cover all changes that you might contribute to any Oracle-sponsored open-source community including not just OpenDMK but also, for example, GlassFish, NetBeans, etc. If you've already signed the OCA or the former SCA (Sun Contributor Agreement) in order to contribute to some other Oracle-sponsored community then you do not need to sign it again in order to contribute to OpenDMK. (You can learn more about the OCA by consulting its FAQ.)
If you have any question regarding the Oracle Contributor Agreement please have a look at the Oracle Contributor Agreement (OCA) FAQ.
