The only thing I can think of is to look at the code in JBossAS that reads the *-ds.xml file to configure a datasource, and use that code as the basis for your code to read your configuration file to configure a data source. Of course, you could instead create a *-ds.xml file based on your configuration file and then use that. My guess is that the first alternative (first paragraph above) would take several months of effort, and the second alternative (second paragraph above) would take several minutes.
