How do I execute a PreparedStatement for every JDBC Connection

[chancelanding]

For every database connection, the legacy application executes a prepared statement on the JDBC connection, that effectively sets what the connection can read in the database. For every database connection I need to execute a simple script on that connection before executing any additional queries.

How should I go about getting a JDBC connection with this statement executed.  I have looked into creating a DataAdapter that models the Mondian adapter, adding the additional configuration value.  I can do this however I am stuck on how I can get the DataAdapterServiceFactory registered in the ExtensionsRegistry. 

I have solved this in our application by passing the report a JDBC Connection object where I have execute the PreparedStatement ahead of passing the connection to the report.  How do I do the same thing in Jasper Studio/Server, i.e. an external entity?
