It used to work fine. But after a restart it fails to deploy itself. The error message from logs is ERROR com.appiancorp.plugins.LoggingPluginEventListener - Failed to enableen-USTelligent Community 12RE: Hi,<br /><br />After a recent server restart we are facing problems with our smahttps://community.appian.com/thread/10036?ContentTypeID=1Mon, 16 Jun 2014 11:47:03 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:546b35bf-8d6c-426a-be99-6d795f188872sujithakwe created a duplicate version of the plugin with a new name and deployed that again and made it work. But facing this issue again. The following steps result in the error:<br />1) We have 1 single xsd file which contains all the CDTs (around 20) used by the application. We are in early development phase, so we regularly update the XSD and import that into Appian (and do Impact Analysis to make sure everything is mapped correctly). The CDT associated with the smart service has not been modified in the updated XSD and the updated XSD is imported successfully into Appian.<br />2) The smart service continues to work after this import.<br />3) Server is restarted for some maintenance activity. Now, the smart service fails to deploy itself with the error described above.<br />How to avoid this? Should we not import the cdt again if it is associated with the smart service (though in our case there was no modification to the smart service associated CDT)? What would be a quick and easy solution than to recreate and deploy the plugin again?<br /><div style="clear:both;"></div>RE: Hi,<br /><br />After a recent server restart we are facing problems with our smahttps://community.appian.com/thread/9919?ContentTypeID=1Wed, 11 Jun 2014 02:57:54 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:d130c462-e23f-4e89-889d-cb30b1310241Mahesh SangaThis happens if any of the input or output was changed/removed. make sure the data type is same as the new smart service data type. Try to clear the osgi-cache and re-start the server. If you want to change the datatype or any input to the existing smart service change the key of the smart service.<br />see here: <a href="https://forum.appian.com/suite/wiki/73/Custom_Smart_Service_Plug-ins#Deployment">forum.appian.com/.../Custom_Smart_Service_Plug-ins</a> Issues<div style="clear:both;"></div>
