I created a trigger and class in by Sandbox and deployed them to production. Now, I would like to drop the class and trigger in production but I cannot do so. I have attempted using the Apex and Force.com toolkits. The best I have been able to do is comment out the code so they do nothing and then redeploy.

Here's the message from the Apex Toolkit log:
DEBUG [2008-01-22 09:50:38,490 {HH:mm:ss}] (ApexArtifactService.java:compileTestSave:330) - Delete [1] Apex Triggers

And from the Force.com log (Not showing full stack track for error... let me know if you need it):
ERROR [2008-01-22 09:39:09,325 {HH:mm:ss}] (RefactorService.java:performRemoteDelete:664) - Unable to perform server delete
com.salesforce.toolkit.remote.ToolkitConnectionException: java.lang.RuntimeException: Failed deployment: UNKNOWN_EXCEPTION msg:null: Cannot complete this operation. Cannot delete classes/triggers in production.  Use compileAndTest verb to delete. : null

Thanks,
