如何从Java写入Windows事件日志？

Answer 1

Log4J is a Java-based logging utility. The class NTEventLogAppender can be used to "append to the NT event log system". See the documentation here:

http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/nt/NTEventLogAppender.html

Edit: There is a newer version, Log4j 2 "that provides significant improvements over its predecessor."

Answer 2

You can use JNA to write to the Event Log directly without the need of any native DLLs. See Advapi32 and Advapi32Util classes for various event log methods (ships since JNA 3.2.8).

If you're using Log4j, consider Log4jna instead of NTEventLogAppender.

Answer 3

Back in 2001 JavaWorld published an article on how to write messages to the Windows NT Event Log. Or, you can take a look at the Log4j NTEventLogAppender class.

Answer 4

You can also use the eventcreate command on Windows XP Pro and above.

String command = "eventcreate "
               + " /l APPLICATION"
               + " /so \"" + applicationObjectName + "\""
               + " /t " + lvl
               + " /id " + id
               + " /d \"" + description + "\"";

Runtime.getRuntime().exec(command);

For XP home and lower, you could create a vbs application that writes using the wscript.shell.eventcreate method. However you sacrifice the ability to specify source.
