Anyone here who is working in distributed computing using jini? I have tried in the last months, but jini seems like stuck.

Thanks.

The jini.org site seems to be pretty active and is probably the best place to get help.

What do you mean by "stuck"?

Compared to other java technologies jini is much less active. I want to work with jini for distribute computing but a have found very few active projects using jini. Maybe I just looked in the wrong place but even I found that there are project to generate a java spaces api without the jini stuff. The jini.org site looks really fine but when I tried out the tutorials and examples, I found that they are out of date of the current jini distribution. The examples ran fine in a local machine but when I tried to run them in a distributed way the connections didn�t succeed. I converted to rmi objects and did the same thing and worked just fine. I think I miss configured something but after three days didn�t get the correct configuration following the site instructions step by step.

Would you recommend me to use rather plane rmi to do the distributed stuff? I mean jini concept sounds as just the api to use in distributed environments but I can�t invest a lot of time in a project if there isn�t a strong community supporting jini.

I understand your concern - Jini does not get as much publicity as I think it should, and after much dithering there is still not a simple install and go package.

Sun is trying to create an open-source Jini project at the Apache Software Foundation. Take a look at this proposal (only a few days old).

Do you have a specific project in mind?

Most of the activity I see is using Javaspaces and there are some free Javaspaces releases.

I�m working in a grid computing enviroment. So JINI just seems perfect in paper. But when I began trying to use it I found I has little commercial use.

I�m in the point where I need to decide to use an already working api for java grid computing. Or trying to do something new as adding functionality to a working api. The thing is that working api use RMI or plain sockets and it would be interesting to port some of their functionalities to JINI ground.
 
I agree. Here's the link: http://aspose.com/file-tools
