Hi Gareth,
You will probably want to get the latest version of the source. I just
checked in some changes last night that make the appserver package a little
easier to configure. An example program which uses it looks like this:
=========== Begin test.java =================
import org.apache.log4j.examples.appserver.AppServerCategory;
import org.apache.log4j.examples.appserver.AppServerPropConfigurator;
import org.apache.log4j.Category;
import org.apache.log4j.Priority;
public class test
{
public static void main(String[] args)
{
// AppServerPropConfigurator.configure("test.properties");
Category cat = AppServerCategory.getInstance("some.cat");
cat.l7dlog(Priority.DEBUG, "msg01", null);
cat.debug("This is a debug statement.");
cat.info("This is an info statement.");
cat.warn("This is a warning statement.");
cat.error("This is an error statement.");
cat.fatal("This is a fatal statement.");
cat.shutdown();
}
}
=========== End test.java ===========================
Note that the call to the configurator is commented out. I placed it in
there to test it (and this is how one would use it). But the static
initializer in AppServerCategory can also do the job. My configuration
file looks like this:
=========== Begin test.properties ========================
log4j.appserver.factory=org.apache.log4j.examples.appserver.AppServerCategoryFactory
log4j.appserver.factory.server=TestServer
log4j.appserver.factory.component=TestComponent
log4j.appserver.factory.version=SomeVersion
log4j.appserver.factory.msgfile=app_messages
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.examples.appserver.AppServerPatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%h:%s:%b:%v] %m%n
log4j.appender.dispatch=org.apache.log4j.net.SocketAppender
log4j.appender.dispatch.remoteHost=case
log4j.appender.dispatch.port=32496
log4j.appender.dispatch.locationInfo=false
log4j.category.some=DEBUG,stdout
============ End test.properties =========================
And my message file looks like this:
============ Begin app_messages.properties ===============
msg01=This is message number one.
msg02=Second example of a message.
msg03=The parameter is {0}.
============ End app_messages.properties =================
I run the program like this:
java -Dlog4j.defaultInitOverride=true -Dlog4j.configuration=test.properties
test
And I get the following output:
============= Begin Output ======================================
E:\samples\appserv\test>java -Dlog4j.configuration=test.properties
-Dlog4j.defaultInitOverride=true test
[molly:TestServer:TestComponent:SomeVersion] This is message number one.
[molly:TestServer:TestComponent:SomeVersion] This is a debug statement.
[molly:TestServer:TestComponent:SomeVersion] This is an info statement.
[molly:TestServer:TestComponent:SomeVersion] This is a warning statement.
[molly:TestServer:TestComponent:SomeVersion] This is an error statement.
[molly:TestServer:TestComponent:SomeVersion] This is a fatal statement.
E:\samples\appserv\test>
============= End Output ==========================================
If it is not practical for you to download the latest source, let me know.
I can send you a "helper class" (an initialization routine) that will get
everything started under the old system.
