JAVA RESEARCH LICENSE
The JRL was created specifically for universities and researchers who want to use Java[tm] technologies as subject matter for learning and research. It was written to simplify and relax the terms of the existing "research" section of the current SCSL.
1. What is the Java Research License (JRL)?
The JRL is a license that was created specifically for universities and researchers who want to use Java technologies as subject matter for learning and research. it was written to simplify and relax the terms of the existing "research" section of the current SCSL.
2. Have any terms of the license changed?
Yes. There is greater flexibility in working with the code for research use and the license is world wide, excluding Denied and Restricted Parties List (embargoed countries, etc.) The language has been clarified and separated from the commercial terms so researchers and teachers should feel more confident with their usage rights. In addition, this latest version of the JRL has been updated to better clarify that the license does not impose restrictions upon those who wish to work on independent open source projects.
3. Who is the JRL target audience?
This license is designed for the research community. This includes schools and universities as well as companies and individuals, who want to examine the technology source code for personal interest or research & development purposes. This license allows a licensee to work alone or with other licensees.
4. Can I use the JRL for a project on java.net?
Yes, we encourage you to. If you have accepted the terms of the JRL, and if you are developing code based on a Java download, you can choose to use this license as an alternative to the SCSL for your research/development project on java.net.
5. How do I become a "JRL Licensee?"
To agree to the terms of the JRL, you must agree to the license for one of the supported platforms, profiles or extensions.
6. What code is supported under the JRL?
Sun is supporting the JRL for most Java technologies it releases through the Java Community Process as well as research projects surrounding this code.
7. Does this license require a click-through acceptance of terms?
Yes. For enforceability, Sun requires a click-through license.
8. When do I need to get a commercial license?
This research license is only for initial research and development projects. If you decide to use your project internally for a productive use, and/or distribute your product to others, you must sign a commercial agreement such as the Java Distribution License (JDL) and meet the Java compatibility requirements.
9. Does this license cover all versions of Java?
The JRL was designed to be usable by all Java platforms (i.e., Java SE, Java EE and Java ME), profiles and optional packages which are either newly released by Sun through the Java Community Process or are currently covered under Java SCSL licenses. While not every Sun Java technology has been released under the JRL, many have. Please contact JRLFeedback@sun.com if you have any questions.
10. Am I required to purchase a support contract from Sun under this license?
No. A separate support contract is available but is not required.
11. Is the TCK available for research purposes?
Yes, a standalone TCK license is available.
12. Am I required to keep my research "Java Compatible?"
No. The license encourages you to innovate and experiment using Java technology source code. It is expected that research implementations will not be compatible with the Reference Implementation from Sun. This is OK.
13. Can I publish my source code at a conference, and in white papers?
Yes, you may publish your work in the usually accepted academic manner as long as you reference the Java Research License and include the correct copyright information.
14. Can I share my modifications with other researchers?
Yes, provided that the other researchers have accepted the JRL.
15. Can I distribute binaries of my research code?
Yes. You can distribute your binaries for research purposes under a license of your choice that complies with the terms of the JRL (e.g., includes copyright notices and references the JRL).
16. I am a current SCSL licensee, and want to use the JRL for research. Can I do this?
Yes. Current SCSL licensees can choose to use the JRL for research purposes, but they must click through the new license, and use the JRL notification in their work.
17. I am a university professor and would like to use JRL source as part of my students' research and classwork. How do I administer this?
You may distribute source and binaries covered under the JRL to your students for research or classroom work as long as you include a copy of the JRL with these materials and clearly specify to your students that their work with the licensed technology is done under its terms. Reasonable care should be taken to restrict access of all JRL materials (including its modifications) to you and your students.
18. Does the JRL prevent me from being able to create an independent open source implementation of the licensed technology?
The JRL is not a tainting license and includes an express Òresidual knowledgeÓ clause which says you're not contaminated by things you happen to remember after examining the licensed technology. The JRL allows you to use the source code for the purpose of JRL-related activities but does not prohibit you from working on an independent implementation of the technology afterwards. Obviously, if your intention is to create an ÒindependentÓ implementation of the technology then it is inappropriate to actively study JRL source while working on such an implementation. It is appropriate, however, to allow some decent interval of time (e.g. two weeks) to elapse between working on a project that involves looking at some JRL source code and working on a project that involves creating an independent implementation of the same technology.
19. May I co-mingle JRL source and source code covered under another license or agreement?
This is tricky and highly dependent upon license terms. Sun grants you the right to distribute JRL source, binaries and their modifications under the JRL or under a Sun approved commercial license. To co-mingle source or binaries covered under another license or agreement (including in some cases a company's employee agreement), you must have the right to release that code under the JRL as well.
20. Who can I contact if I have additional questions or comments?
