This appendix describes how to troubleshoot an integrated Excel workbook and generate log files when you encounter problems during development. It also describes possible solutions for a number of errors and problems (such as version mismatch, 404 error, and Oracle ADF tab not visible in integrated Excel workbook) that you may encounter.
This appendix includes the following sections:
Section C.1, "Verifying That Your Fusion Web Application Supports ADF Desktop Integration"
Section C.2, "Verifying End-User Authentication for Integrated Excel Workbooks"
Section C.3, "Generating Log Files for an Integrated Excel Workbook"
Section C.4, "Common ADF Desktop Integration Error Messages and Problems"
The property inspector does not validate that values you enter for a property or combinations of properties are valid. Invalid values may cause runtime errors. To avoid runtime errors, make sure you specify valid values for properties in the property inspector. For more information about the property inspector, see Section 5.6, "Using the Property Inspector."
Using a specific URL, you can verify that the Fusion web application is running the ADF Desktop Integration remote servlet (
adfdiRemote), and the version of ADF Desktop Integration. This information can be useful if you encounter errors with an integrated Excel workbook. For example, you can determine whether the ADF Desktop Integration remote servlet is running when you are troubleshooting an integrated Excel workbook.
To verify that the ADF Desktop Integration remote servlet is running:
Log on to the Fusion web application.
Type the concatenated values of the workbook properties
RemoteServletPath into the address bar of your web browser. This corresponds to a URL similar to the following:
If the ADF Desktop Integration remote servlet is running, a web page returns displaying a message similar to Figure C-1.
If end users of an integrated Excel workbook do not get prompted for user credentials when they invoke an action that interacts with the Fusion web application configured with ADF security, it may mean that security is not configured correctly for either the integrated Excel workbook or the Fusion web application. You can verify that your secure Fusion web application authenticates end users and that it is security-enabled by carrying out the following procedure.
To verify that a secure Fusion web application authenticates end users, in the web browser's address bar, enter the URL that you used to verify whether ADF Desktop Integration remote servlet is running. For more information, see Section C.1, "Verifying That Your Fusion Web Application Supports ADF Desktop Integration." If the Fusion web application is security-enabled, it will request that you enter user credentials.
For more information about securing your integrated Excel workbook, see Chapter 11, "Securing Your Integrated Excel Workbook."
ADF Desktop Integration can generate log files that capture information based on events triggered by the following pieces of software within ADF Desktop Integration:
HTTP filter and the ADF Desktop Integration remote servlet on the web server (server-side logging)
For more information about server-side logging, see Section C.3.1, "About Server-Side Logging."
Excel workbook which you integrate with your Fusion web application (client-side logging)
For more information about client-side logging, see Section C.3.2, "About Client-Side Logging."
To know more about server-side logging, see the "Server-Side Logging" section in Administering Oracle ADF Applications.
You can configure ADF Desktop Integration to save logs of triggered events on the client. By default, no log files are generated. For more information about how to configure ADF Desktop Integration module to save logs, see Section C.3.2.1, "How to Configure ADF Desktop Integration to Save Logs.".
ADF Desktop Integration provides logging tools to generate event logs and make them easily accessible. The logging tools are located in the Logging group of the Oracle ADF tab, and are available in both the design mode and the test mode.
Figure C-2 shows the logging tools in the Oracle ADF tab.
The Logging group provides the following buttons:
Displays the Logging Console window, which enables you to review the recent log entries while you are developing and testing the integrated Excel workbook. The console displays entries that are logged while the console is open. Figure C-3 illustrates the Logging Console window with error log entries.
The console is a resizable, non-modal window with a buffer size of 64,000 characters. When the buffer is full, the old entries are removed. To save log entries, select and copy them to a text file.
The dialog has the following buttons:
Set Level: Click to set the log output level. The button opens the Logging Output Level dialog, where you can choose the desired log output level.
Clear: Click to clear the log buffer.
Close: Click to close the dialog.
A common Logging Console window logs entries for all open integrated Excel workbooks.
Set Output Level
Prompts you to choose the log output level. Table C-1 describes the log levels that client-side logging supports.
Table C-1 Client-Side Logging Levels
Captures critical information.
Captures information about severe errors and exceptions.
Captures irrecoverable conditions.
Captures lifecycle and control flow events.
Captures detailed information about the execution flow of the application.
No logs are captured. This is the default value.
The log output level applies to all listeners for a given logger.
Add Log Output File
Creates a new temporary logging listener to direct logging output to the specified file or format. In the Add New Temporary Logging Output File dialog, choose the desired file output type (text or XML), and specify the path and file name of the log output file.
The temporary listener directs the logging output for the current Excel session only, and is not registered in the ADF Desktop Integration configuration file. After you close the integrated Excel workbook, the temporary listener is removed.
When you click the Add Log Output File button, a new listener is created. The new listener does not replace any existing listener defined in the ADF Desktop Integration configuration file, or any other temporary listener.
Reloads the ADF Desktop Integration configuration file. The ADF Desktop Integration configuration file determines the type of information logged by ADF Desktop Integration. It also determines the location and the output format of the log file.
For more information about the creation and configuration of the ADF Desktop Integration configuration file, see Section C.3.2.2, "About the ADF Desktop Integration Configuration File."
The ADF Desktop Integration configuration file is saved as
adfdi-excel-addin.dll.config in the Designer edition, and as
adfdi-excel-addin-runtime.dll.config in the Runtime edition. To determine the correct file name and location, click the About button in the Workbook group of the Oracle ADF tab. In the dialog that opens, click the Properties tab, and consult the Configuration entry for file name and location of configuration file.
For more information about elements of the configuration file, see the "Configuration File Schema for the .NET Framework" section in Microsoft Developer Network documentation. For more information about trace and debug settings, see the "Trace and Debug Settings Schema" section in Microsoft Developer Network documentation.
Example C-1 shows a sample configuration file, one of many valid ways to configure client-side logging, that generates two different log files with different formats (
.xml). The file captures different types of information such as
DateTime at a
Verbose logging level.
Example C-1 Sample Configuration File
<?xml version="1.0"?> <configuration> <system.diagnostics> <sources> <source name="adfdi-common" switchValue="Verbose"> <listeners> <add type="System.Diagnostics.DelimitedListTraceListener" name="adfdi-common-excel.txt" initializeData="c:\logs\adfdi-common-excel.txt" delimiter="|" traceOutputOptions="ThreadId, ProcessId, DateTime"/> <add type="System.Diagnostics.XmlWriterTraceListener" name="adfdi-common-excel.xml" initializeData="c:\logs\adfdi-common-excel.xml" traceOutputOptions="None"/> </listeners> </source> </sources> </system.diagnostics> </configuration>
Users who do not have access to the directory that stores the ADF Desktop Integration configuration file can change the location where log files are saved, and the logging level by setting values for user environment variables. You can add two user environment variables to configure the logging level and location for XML log files.
To add or configure user environment variables on Windows:
Click the Windows Start button and then click Control Panel.
In the Control Panel, click System, and then Advanced System Settings.
In the Advanced tab of System Properties dialog, click Environment Variables.
In the Environment Variables dialog, click New under the User variables for username input field, and add variables as described in the Table C-2.
Table C-2 User Environment Variables to Configure Logging
|Enter a variable named...||With a value...|
That defines the directory path and file name for the XML file that captures logging information.
The directory that you specify here must exist before you add the
That specifies the level of logging. Table C-1 lists valid values.
adfdi-common object is an instance of the
TraceSource class from the
System.Diagnostics namespace in the Microsoft .NET Framework. This object is used to generate log files that capture information about events triggered by the Excel workbook that you integrate with your Fusion web application. To know the location of the log file, check the Log Files attribute in the Properties tab of the About dialog.
For more information about the
TraceSource class, see Microsoft Developer Network documentation.
