Problem Description:
You are getting this error when running a new report:
[toc]
"Processor of type com.jaspersoft.jasperserver.inputcontrols.cascade.handlers.converters.DataConverter for class net.sourceforge.jtds.jdbc.ClobImpl not configured."
Workaround:
You might get this error even when clob datatype is not used. For example, you may be using a JTDS jdbc driver. The trouble may be with a column with datatype of nvarchar(max).
This datatype is interpreted by jasperserver as clob and hence the failure. Try using something like this: nvarchar(400)
