I'm learning about JBPM, and I'm reading the docs. I followed the installation procedures on the tutorial (chapter 3), but now I have not a clue to where to go. So I'll have to ask these (stupid) questions, please be patient.
No worries, we'll try to help.
but now I have not a clue to where to go.
If what you're asking is where do you go next to start developing, my example application might help you. It's located here: https://community.jboss.org/wiki/SimpleJBPM54InsideJBossAS711WebAppExample I think I was in the same sort of place you are about what to do next, and have managed to peice together this example web app...
How can I use Eclipse to use JBPM now?
By default, when you run ant start.demo, Eclipse should have started and been all configured and ready to go... But you do not need to install the JBPM stuff into Eclipse through the installer, you can just add the plugins through update sites. Still, the installer is a good way to try it out. Further on in the doucmentation there is a section on using the designer and the console.
Can this "demo" be used on production? If not, where can I find a tutorial that shows how to setup a production jbpm? I googled and googled, but up to no avail.
I'm not 100% sure, but I think it can be. I did find some forums/wikis out there about how to install the stuff without using the installer. One way to do it is to walk through the build.xml and see what all it does, but like I said, I think I have seen some more descriptive instructions out there in various places... as I understand it at this point, the installer doesn't do a whole lot more than download stuff and put them in the right places inside the JBoss file structure and eclipse file structure.
