Working with the Datasource Service Factory
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):
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:
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.
