Trace/Diagnostics output from ADF BC Web Services using FMC (EM) in OFM 11g R1

When you deploy your ADF BC Application module as a Web Service interface you can take advantage of Fusion Middleware Contol (EM) to trace the web service execution from FMC (EM) itself as I will show here.

Note: This is only applicable to ADF BC Web Services, the same steps won't work for JAX-WS or PLSQL web services created in JDeveloper 11g R1.

The documentation for Service-Enabled application modules can be found here.

Oracle® Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework
11g Release 1 (11.1.1)

Part Number B31974-03
11 Integrating Service-Enabled Application Modules
http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcextservices.htm#CJAJGIEB

In order to do this we need to achieve 3 steps here.

1. Setup Fusion Middleware Control (EM) in your domain

In short your domain will need to be setup as per these steps.

2. Deploy an ADF BC App Module as a Web Service Interface

Note: It is assumed you have a client method exposed in your ADF BC application module. An example of such a method is as follows. You will need to ensure the method is exposed as a client method.


public String getVersion ()
{
return getSession().getVersion();
}

2.1. Right click on your application module XML file and and select "Open {app module name}"
2.2. Select "Service Interface"
2.3. Select the + symbol
2.4. Enter in the service interface details.
2.5. Click next
2.6. Shuttle across the methods you wish to expose.
2.7. Ignore the "Service View Instances" and click next
2.8 Click Finish.

You end up with something as follows in the application navigator.





















2.9. Now we need to create a deployment profile which we do by double clicking on the proejct to invoke the "Project properties" dialog.
2.10. Select "deployment"
2.11. Click New
2.12. Select the archive type as "Business Components service Interface"

2.13. Give it a name and press Ok

At this point you have created an EJB JAR file , which you can deploy by using the menu item for the workspace "Deploy" and targeting an Application Server Connection for your OFM 11g R1 server. Once deployed you should end up with output as follows.

3. Use FMC (EM) to trace the ADF BC web service execution.


3.1 Log into FMC (EM) as follows

http://{server}:{port}/em

3.2 In the navigator pane, expand WebLogic Domain
3.3. Expand the domain
3.4. Select the desired server from the list.
3.5. From the WebLogic Sever menu, select Logs > Log Configuration
3.6. On the "Log Levels" tab you need to select "Loggers with persistent Log Level State", then expand the "Specify Loggers"
3.7. At the bottom and enter the logger name "oracle.webservices" and optionally setup the "
Diagnostic Logging Level" you wish to use.
3.8. Press Apply.

Now at this point we have to restart the server.

Once re-started log back into EM and verify the Log configuration shows "oracle.webservices" as shown below.














Now we can test our web services as shown in this entry and verify we get web services diagnostics logging placed into the log file "debug_ws-diagnostic.log" which would be in a directory as follows $DOMAIN_HOME/servers/{managed-server-name}/logs

An example of the output is as follows

You can also view the log file from FMC (EM) as follows
:

- From the WebLogic Sever menu, select Logs > View Log Messages
- Click on "Target Log Files" button.
- In the log files table select the row containing "debug_ws-diagnostic.log" and press the button "View Log File".
