JCo version 3.0 - how to set connection properties?

I'm in the process of migrating from SAP JCo 2.1 to the recently release JCo version 3.0. I don't understand the new process of defining destinations and setting connection properties. The SAP JCo 3.0 example is called StepByStepClient, and that example uses a stored properties file, and the JCo 3.0 documentation has the following warning, but does not provide any further info on how you should actually perform this in a real situation:

"For this example the destination configuration is stored in a file that is called by the program. In practice you should avoid this for security reasons."


Properties connectProperties = new Properties();
connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, "value" );
connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR,  "value" );
connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "value" );
connectProperties.setProperty(DestinationDataProvider.JCO_USER,   "value" );
connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, "value" );
connectProperties.setProperty(DestinationDataProvider.JCO_LANG,   "value" );
connectProperties.setProperty(DestinationDataProvider.JCO_POOL_CAPACITY, "value" );
connectProperties.setProperty(DestinationDataProvider.JCO_PEAK_LIMIT, "value" );

createDataFile(ABAP_AS_POOLED, "jcoDestination", connectProperties);

JCoDestination destination = JCoDestinationManager.getDestination(ABAP_AS_POOLED);
JCoFunction function = destination.getRepository().getFunction("BAPI_SALESORDER_GETSTATUS");

I don't understand the connection between getDestination and DestinationDataProvider.

I am building some web-based inquiry screens using Tomcat that use JCo to extract R/3 data and I want to define the connection properties outside of the code for easy manipulation when moving from test to prod. I don't use J2EE - JNDI lookups.

Has anyone else migrated to JCo 3.0? Can you provide an explanation of how this should be perfomed?

Thanks, points to be awarded.
