Polling for changes in a database has been a requirement for systems for a very long time. With Oracle BPEL, of course, this need exists and we will review one way you can go about this:
Create a BPEL that would poll the database periodically for records with a specific flag.

In early 2008, Oracle allowed you to enable WebCenter 11g and SOA 11g Tech Previews through the Oracle JDeveloper 11g Technology Preview.
At this point, mid-2009, this is somewhat outdated. The actual WebCenter 11g release (not available for download by Oracle) has quite an enhanced environment, features, etc. I don’t know the timing details exactly, but I imagine that the tech preview was put together before the BEA acquisition decisions were finalized and certainly before they were fully integrated.
WebCenter 11g should be a fantastic product taking the best of many Enterprise 2.0 products and services that Oracle has either acquired or partnered with.
Stay tuned for more information as releases get closer.
Below is a link to a PDF document containing all (or most of the screens) you will find when going through the JDeveloper 11g install on Windows (XP or Server 2003).
The install itself is very easy without many options, so you will not see any commentary alongside the screenshots. However, if you do have questions about it, feel free to ask.

I find myself going through installers sometimes and wondering what all the words were that were flashing in front of me. Someone certainly put some real thought and care into the wizards as well as some of the slight advertising that is generally part of installers like JDeveloper’s. So, this time around, I just included them all for your perusal.
I was running into issues with my Jdev being inadequately slow, hanging, or freezing when working with large BPEL process even though the computer CPU and memory were not even close to maxed out. A little trick I learned in the past to help this problem is increasing the heap size for JDev to use.
If you haven’t already, download Oracle JDeveloper 11g for free using the links below or directly from the JDeveloper 11g Download Page. The Oracle JDeveloper team has been hard at work making this IDE really work as it becomes even more central to developing the next generation of Oracle products.
Below are the links to the various JDeveloper 11g Update 2 (Build 5205)
