I have created a jasper report using jasper studio:
-main query from oracle DB
-another dataset from SQLServer
-load the jdbc driver using parameter and assign the "Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver")" to its Default-Expression
-making a connection for a new dataset(SQLServer) using parameter and assigning connection string of sqlserver in default-expression.
-the report is running successfully local with jasper studio but when call it from oracle apex this error is shown to me

• i tried to send connection string as parameter , but i still have the problem with JasperReportIntegration to declare these classes
