Changes in 5.6

The following changes in 5.6 and later can significantly affect your deployment:

Removal of commercial JDBC drivers: if you're using a commercial JDBC driver, you need to copy it to the correct location in your upgraded JasperReports Server.
Changes to OLAP engine: Due to change between version of the OLAP engine, if you use Jaspersoft OLAP’s XML/A functionality to connect to a remote JasperReports Server’s XML/A sources, you must take additional steps to complete your upgrade to 5.6.

Removal of Commercial JDBC Drivers

The following commercial database drivers were removed from the JasperReports Server 5.6 package: Oracle, SQL Server, or DB2. You'll need to obtain a JDBC driver before running the upgrade. In this case, for Oracle, because you most likely have an Oracle JDBC driver in your existing JasperReports Server instance, it's simplest to copy it from that location:

Copy from: <js-install-existing>/buildomatic/conf_source/db/oracle/jdbc/<driver-name>.jar

Copy to: <js-install-5.6>/buildomatic/conf_source/db/oracle/jdbc

Changes to OLAP Engine

If you use Jaspersoft OLAP’s XML/A functionality to connect to a remote JasperReports Server’s XML/A sources, you must take additional steps to complete your upgrade to 5.6. This is because of a change between versions of the OLAP engine.

Once the new version of JasperReports Server is installed and running, locate all the XML/A connections that point to a remote JasperReports Server instance. Then edit the DataSource field to specify JRS as the DataSource portion of its value.

For example, in previous versions, the Foodmart XML/A connection specified:

Provider=Mondrian;DataSource=Foodmart;

During upgrade, this connection must be changed to:

Provider=Mondrian;DataSource=JR

Note that for 5.6, the trailing semicolon should be removed (the older 5.5 syntax includes a semicolon at the end).

For more information about creating and editing XML/A connections, refer to the Jaspersoft OLAP User Guide.

Note that if your instance hosts multiple organizations, XML/A connections will fail for superuser. This limitation applies exclusively to the superuser account. To test connections in servers that host multiple organizations, we recommend that you log in as jasperadmin or another administrative account other than superuser.

One reason you might have XML/A connections to remote instances of JasperReports Server is to create a load-balanced Jaspersoft OLAP environment. For more information, refer to the Jaspersoft OLAP Ultimate Guide.
