Hey Guys.. I am working with Jasper Server for 2 days now, so I am completly new with this. My problem is that a don't know how to create an new Datasource in the Respository. I also tried it from iReport but it didn't work. I used the JasperServer-Plugin to copy the in iReport created Report to the server. That worked perfect but when I want to view the report there is an error: com.jaspersoft.jasperserver.api.JSExceptionWrapper: com.microsoft.sqlserver.jdbc.SQLServerDrivercom.jaspersoft.jasperserver.api.JSExceptionWrapper: java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriverIt seems like there is a Problem with the SQL-Server driver, but i imported it with the Report from iReport an there it worked.The datasource is a MS SQL-Server.How can I fix this Problem?Thanks in advance...
