Hi I am trying to setup a JDBC-ODBC Datasource in Jaspersoft Server V5.5. The same driver and url work correctly in iReport v5.5. I am using the correct driver sun.jdbc.odbc.JdbcOdbcDriver (I assume). The same driver works with ireport. The url I am using is jdbc:odbc:testdbisam (testdbisam is my DSN). The message I get is : [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified Show Details What am I doing wrong ?
