Bit #29 - Dynamically configure ADF trace logs in WebLogic

ADF-specific logging can be dynamically configured in WebLogic via the wlst script. Ensure that you run the wlst script that is located in oracle common directory (and not the one in the WebLogic server home). Then connect to the administration server and use the setLogLevel() command to change the appropriate logger's level. To configure Business Components logs specify oracle.jbo as the logger. Similarly to configure the ADF Controller and ADF Faces logs use the oracle.adf.controller and oracle.adf.faces loggers respectively. For the example below, the ADF application is deployed on ManagedServer1. As mentioned, these changes to the logging configuration can be done at run-time without the need to re-start the server.


Example:

wlst
connect('weblogic','weblogic1', 't3://192.168.5.134:7001')
setLogLevel(target='ManagedServer1', logger='oracle.jbo', level='FINEST')


Context:

ADF BC
ADF Faces
ADF Controller

Bit #8 - Executing an operation binding programmatically from a backing bean

To access an OperationBinding in a backing bean, call getOperationBinding() on the DCBindingContainer - the data control binding container - and specify the operation binding identifier that you assigned to the operation during the declarative binding process. Once you have the OperationBinding call its execute() method to execute it. If you need to pass any arguments to the operation, call getParamsMap() to get the operation parameters map and put() on the map the specific argument. Call getResult() after the call to execute() to retrieve the result of the execution. Here is an example.


Example:

        // in the context of a backing bean

         OperationBinding operation = bindings.getOperationBinding("operation_name");

         operation.getParamsMap().put("parameter_name", parameterValue);

         operation.execute();

         if (operation.getResult() != null) {
                  Boolean result = (Boolean) operation.getResult(); // cast to the expected result type
        }

Backing Bean
