Why is my project private?

All projects are created private by default, since over 90% are abandoned before any work is done or they are spam. Once you have a license, a clear description and a little bit of work done (first code checked in or documentation or bug tracker set up, etc) let me know and I will make it public for you and move it to the correct community. Dealing with projects this way helps keep junk projects from clogging up our catalog and search engine hits. More details about the workflow are at

Why do I only get five projects? How do I increase my number of projects?

The limit is in place to prevent spambots from automatically creating spam projects. If you need more projects, simply email communitymanager at and we’ll be happy to increase your limit.

Who can see/do stuff to my project?

What are the project features?

How can I migrate a project from to

The plan to merge projects into is definitely still on, but we don't have a schedule for it. There will be a big announcement when we get ready to do this and all project owners will be notified by email ahead of time.

How do I write a blog?

You need to be approved by our editor (not hard, just send him an email with everything spelled right and reasonable grammar) and it needs to stay on topic about things of interest to the community. If you want to do a one-off post on another blog and have it featured, you can do that too. Either way, the contact is Kevin Farnham. His email is editor at

How do I contact individual members on

Just append to any user name. So to contact helen, I would send a message to helen at You email is forwarded to the email address the user entered when they registered for

I see an error/broken link or have a question on a project - how can I contact the owners of a project?

If the project home page lists the owners, you can contact them directly (see previous question). However, if you want to contact all of the owners at once, or if the project page does not list the owners (some customized pages do not show the owner usernames), you can always reach the owners of a project by sending email to admins at So for example, if you wanted to email the owner(s) of project Incubator, you would use admins at

How do I change my username?

It is not possible to change your username. If you really need to do that, you need to create a new account. Then you will need to rejoin any projects that you have joined under the current username.

Where can I get support for Java? has updates, patches, training, and just about everything you could need. If you have a coding problem, try asking in our forums.

How can I get Java Magazine?

How do I file a bug?

There are two places to file bugs. Look at your page tab. Does it show the Java cup and steam? Then file your bug at If you see three bars use And, if you get confused, send us an email and we'll point you in the right direction.

How do I report spam?

What is is a premier web-based, open community created to facilitate Java™ technology collaboration in applied areas of technology and industry solutions. is a central gathering place for Java™ technology enthusiasts and existing communities across industries, platforms, and interest groups.

What is the goal of

The goal is to expand the Java™ technology portfolio of applications, tools, and services by promoting conversation and collaboration around development of practical applications across industry groups.

What will developers find on

On, developers can find and post material related to their specialized needs. Through a variety of collaborative tools such as wikis, weblogs, discussion forums, mail lists, and RSS newsfeeds, as well as traditional open source tools like Subversion, Mercurial, Git, and JIRA, allows developers to come to one place to find out the latest news and opinions, have conversations with other developers who share specific interests, and ultimately engage in efficient development efforts using Java™ technology.

Is an Oracle web site? was launched by Sun in 2003 and acquired by Oracle in 2010.  It is financially sponsored by Oracle; the majority of the content comes from companies and individuals outside of Oracle.

How does Oracle benefit from

A thriving community benefits all active participants, including Oracle. By participating in communities, Oracle can create better products, establish new business relationships and partnerships, and engage more closely with developers who are committed to using Java™ technology in innovative and creative ways.

How is Cognisync involved in

What are the specific technologies used to provide the collaborative environment on

At the foundation of is an infrastructure and philosophy that supports open communication and development among peers. It includes project-support tools such as mailing lists, identities and personalities, reputation, weblogs, and wikis. It provides the tools an open source development project needs to be successful; code versioning systems, bug-tracking systems, project roles, forums and mailing lists. It also provides tools for gathering information on what's happening in the industry through RSS newsfeeds.

How can I get involved with

There are many ways to participate. Go to Get Involved for details on participation options. compared to related developer web sites


Does relate to the Java Community Process[sm]?

No. The Java Community Process[sm] (JCP[sm]) program is the formalized, community-based process for evolving and maintaining Java™ technology.  Java™ technology is the only successful binary standard, and the JCP Program defines that standard in the Java[x] namespace.  It charters the evolution and development of all Java™ specifications and APIs.  For more information, see is a resource for developers and others using the Java™ platform to develop innovative applications and to make their work environment more productive.  It provides a catalog of tools and applications that facilitate development using Java™ technologies and encourages groups with common interests to meet and work together.

Will some Java™ Specification Requests be hosted as projects? can support Java™ Specification Requests ("JSR™") projects.  It is up to the JSR expert lead and the Java Community Process[sm] to decide on a case-by-case basis if this forum is appropriate.

How is different from Oracle's other Java™ websites?

The Oracle branded websites are web sites that represent the voice of Oracle and provide materials related to commercial products developed by Oracle. These sites are traditional information portals that focus on Oracle's implementation of Java™ technology. is the place where the entire community has a voice.  Although information on Java™ technology from many sources is available on the site, the emphasis is on application and value-added resource development through collaboration.

Participants benefit by joining with and having access to other members of the community with similar interests. At, they have a centralized meeting place to go for help with their projects. They can leverage the rich set of collaborative tools available for their use. can save the effort and expense of starting a unique, stand-alone web site and allows new projects to instantly be part of the larger community focused on Java™ technology.  Existing web sites can affiliate with by creating a home page in the project catalog and still take advantage of the additional collaborative tools.

If we join, will we be able to better influence the future of Java™ technology?

The Java Community ProcessSM (JCPSM) program is the appropriate place to contribute to the evolution of binary standards for Java™ technology. is intended as a space to collaborate while applying Java™ technology, but in some cases work on may lead to proposal of a Java Specification Request. was envisioned as a suitable place for experimentation, and also as a framework for leading an accepted Java Specification Request.

Can all companies and organizations participate in

Yes.  All companies and their employees interested in Java™ technology are encouraged to participate in, as long as they adhere to the Guiding Principles of the site.


Projects at


What types of projects are likely to get started on

Current projects at have evolved from an interest of one person, and/or a collective interest, or a need among a group of people.  Some of these groups already exist and have been looking for a venue to engage with others.   We have engaged in enthusiastic conversations with:

  • Standards groups that want to collaborate on applications using Java™ technologies, but which have no expertise in site or collaborative code management.
  • Industry-specific application engineers who are looking for a place to reach out to other engineers developing and supporting similar systems.
  • Universities around the world with technologists who want to collaborate on research and need a home.
  • Educators who wish to collaborate on developing new courses on Java™ technologies.
  • Companies that want to expose some ideas to developers during their exploration stages.
  • ISPs and support engineers who have small utilities and tools they are willing to share.
  • Java User Groups that want to share their meeting topics and lectures.
  • Small companies and individuals who are cooking up ideas and looking for a forum of developers.
  • Existing communities and web sites focused on Java™ technology that want to leverage the information shared on and around

I have an idea for a new interest group.  How do I engage the community?

First, we recommend you review wikis and weblogs on the site for conversations that might be related, and scan project homes and their sub-projects for similar efforts.  If you believe an interest group exists related to Java™ technology and there is no suitable venue for members to communicate and/or develop code together, you can solicit people with similar interests with a blog, mail list, or an entry to the incubator.

Is for open source projects only?

Today, open source projects are the only projects supports.




When you request a new project, you will be asked to indicate the license you wish to use.   You can choose one from the list provided or select "other" and add the license of your choice to your homepage documentation.
