Setting Up Your Development Environment

The first time you run the test suite or any application using Log4JNA, Log4JNA attempts to write the necessary entries in WindowsTM Registry. If you don't have Administrator privileges the run fails.

Running Tests

In order for the tests to pass you must run them as Administrator or set up the registry before your first run.

Open a command window as administrator and execute mvn test.

If you are using an IDE launch it as Administrator import the Maven projects and run the tests.

IDE Setup

Please be careful and do not check IDE configuration files into GitHub, you can add the project to your IDE following the instructions bellow.

Eclipse configuration files are already added to .gitignore, please add any configuration file created by your IDE to the ignore file.

Eclipse

See this article to import the Maven projects.

IteliJ IDEA

See this article to import the Maven projects.

NetBeans

See this article to import the Maven projects.

Set up the Registry manually

For Log4JNA Api Tests

The Win32EventlogAppender.dll file is provided in the source as a test asset in <project-location>/log4jna-api/src/test/resources.

The tests configure Log4J programmatically and write into Event Viewer-->Windows Logs-->Application.

  1. Open regedit and browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\
  2. Right click and select New Key, name it Log4jnaTest
  3. Add the following entries to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\Log4jnaTest
Entry name Entry Type Value
TypesSupported DWORD (32 bit) Value (REG_DWORD) 0x7
CategoryCount DWORD (32 bit) Value (REG_DWORD) 0x6
EventMessageFile String Value (REG_SZ) <Full path to>\Win32EventlogAppender.dll
CategoryMessageFile String Value (REG_SZ) <Full path to>\Win32EventlogAppender.dll

The registry should look like this:

For the Demo Application Tests

The Win32EventlogAppender.dll and Log4J 2 configuration files are provided in the source as an application asset in <project-location>/log4jna-demo/src/main/resources.

The default Log4J configuration is log4j2.xml and writes into Event Viewer-->Application and Service Logs-->Win32LogApplication.

  1. Open regedit and browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\
  2. Right click and select New Key, name it Win32LogApplication
    1. Add another key to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Win32LogApplication, name it WinLogger
  3. Add the following entries to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Win32LogApplication\WinLogger
Entry name Entry Type Value
TypesSupported DWORD (32 bit) Value (REG_DWORD) 0x7
CategoryCount DWORD (32 bit) Value (REG_DWORD) 0x6
EventMessageFile String Value (REG_SZ) <Full path to>\Win32EventlogAppender.dll
CategoryMessageFile String Value (REG_SZ) <Full path to>\Win32EventlogAppender.dll

The registry should look like this:
