I was playing around with the DataSource Service Factory today, and I found out how to do a few things. I created datasources, and used them, but I couldn't figure out how to get it to save the datasource. Anyways here's how you create a datasource, it took me a few tries to figure out the ordering of the setDatasource method (since reflection only tells you the datatypes, I had to figure out what each argument was for):

<cfset dsService = CreateObject("java", "coldfusion.server.ServiceFactory").DataSourceService>
<cfset dsManager = dsService.getDman()>
<cfset map = dsService.getDefaults()>
<!--- name, driver class, description, username, password, url, isPooled, timeout, interval, map --->
<cfset dsManager.setDatasource("datasource_name", 
 "macromedia.jdbc.MacromediaDriver",
 "description",
 "username",
 "password",
 "jdbc:macromedia:sqlserver://localhost:1433;databaseName=tester;SelectMethod=direct;sendStringParametersAsUnicode=false;MaxPooledStatements=1000",
 true, 
 1200,
 420,
 map)>

The map variable has some more values you can set (mostly the permissions), but check out the default values by doing a cfdump of the map variable.

The above code will create a datasource that you can use, but it does not persist after the server is rebooted. If you can find a way to make that work please post a comment.

The next code example will list all the installed JDBC drivers, note that we are using the dsService variable from above.

<cfdump var="#dsService.getDrivers()#" label="Installed JDBC Drivers">

To test if a datasource exists:

<cfif dsManager.exists("datasource_name")>
	it exists...
<cfelse>
	it does not exist
</cfif>

To remove a datasource (not sure if this will persist after the server is restarted):

<cfset dsManager.removeDatasource("datasource_name")>

To list all installed datasources:

<table border="1">
 <tr>
 	<td>Name</td>
 	<td>Description</td>
 	<td>JDBC Class</td>
 	<td>JDBC URL</td>
 	<td>JDBC User</td>
 	<td>JDBC Password</td>
 	<td>Interval</td>
 	<td>Pooled</td>
 	<td>Timeout</td>
 </tr>
<cfset nameArray = dsManager.getNames()>
<cfloop from="1" to="#ArrayLen(nameArray)#" index="i">
	<cfset name =nameArray[i]>
	<cfoutput>
	<tr>
		<td>#name#</td>
		<td>#dsManager.getDescription(name)#</td>
		<td>#dsManager.getJdbcClass(name)#</td>
		<td>#dsManager.getJdbcUrl(name)#</td>
		<td>#dsManager.getJdbcUsername(name)#</td>
		<td>#dsManager.getJdbcPassword(name)#</td>
		<td>#dsManager.getInterval(name)#</td>
		<td>#YesNoFormat(dsManager.isPooled(name))#</td>
		<td>#dsManager.getTimeout(name)#</td>
	</tr>
	</cfoutput>
</cfloop>

To purge query cache:

<cfset dsService.purgeQueryCache()>

To verify a datasource (test connection):

<cfif dsService.verifyDatasource("datasource_name")>
	verified
<cfelse>
	not verified
</cfif>

As always remember that this undocumented stuff is subject to change from version to version.
