  1. Hi all!I'm doing a report with two connections. In the main, I use a JSON, for the subreport the following parameter:<parameter name="SUBREPORT_CONNECTION" class="java.sql.Connection" isForPrompting="false"> <defaultValueExpression><![CDATA[java.sql.DriverManager.getConnection("jdbc:oracle:thin:@IP:PORT/DB","USER","PASS")]]></defaultValueExpression> </parameter> <subreport> <reportElement x="0" y="10" width="595" height="200" uuid="693d33ec-8ad9-4e8f-bab9-0339d80b8d94"/> <connectionExpression><![CDATA[$P{SUBREPORT_CONNECTION}]]></connectionExpression> <subreportExpression><![CDATA["name.jasper"]]></subreportExpression> </subreport> The problem is that I get the error Error evaluating expression for java.sql.DriverManager.getConnection("jdbc:oracle:thin.....)Caused by: java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@ The classpath is declared (tested with the ojdbc8 and ojdbc6 drivers in the plugins folder)HELP!
