You should be able to use a ModelControllerClient and change everything you can from the CLI.

thanks for your quick reply.

I dont want change the configuration in the xml file by program. What i want is change it dynamically.

[nickarls]

The changes made through the ModelControllerClient are automatically persisted to the xml.

I think i was not clear, i dont want change the xml. I have read a post about application level log with log4j in jboss 7. But i want to use jboss logging system, so i ask if I can configure my log in my application withou touching standalone.xml and module.

There appear to have been some work done for it according to

https://issues.jboss.org/browse/AS7-514

https://docs.jboss.org/author/display/AS72/Logging+Configuration#LoggingConfiguration-PerdeploymentLogging

but I'm not sure what can be done in runtime.

You can change application logging using the command line:

{code:bash}bin/jboss-cli.sh --connect "/subsystem=logging/logger=com.your.package.name:add(level=DEBUG)"{code}

but this will be persisted in the xml for you.

You can also place the CLI commands in a batch file and execute a bunch of them at once if you want. I think that counts as "programmatically".

Have a look at AS71 CLI Recipes - ScriptedConfiguration.

yes this is what i need, but I must wait till the release of 7.2?

[nickarls]

It's also included in the 7.1.(2/3/4) releases so you could build from those tags. For the community version, you'll have to wait for 7.2.

hi,

I am trying per-deployment log wiht a jboss-as-7.1.3, i try to use jboss-logging, i removed log4j.jar and common-logging jar in my application.

my log4j.properties is loaded, I can see it in the console, my log file is created, but nothing is logged in the file. and my log is not going in the server.log neither.

what i understand is jboss-logging is a log facade, it choose jboss logmanager, log4j, slf4j-logback or jul logmanager when it find it in the class path.  correct me if i am wrong? So how do i know which logmanager is chosen?

thanks in advance.

If used within JBoss AS it will choose JBoss Log Manager. If you want your application to use it's own configuration you'd need to use a logging.properties file. It's very similar to a log4j style properties file.

Here is an example logging.properties file

# Additional logger names to configure (root logger is always configured)
loggers=com.example

# Dump system environment at boot by default
logger.com.example.level=DEBUG

# Root logger level
logger.level=INFO
# Root logger handlers
logger.handlers=CONSOLE

# Console handler configuration
handler.CONSOLE=org.jboss.logmanager.handlers.ConsoleHandler
handler.CONSOLE.properties=autoFlush
handler.CONSOLE.level=INFO
handler.CONSOLE.autoFlush=true
handler.CONSOLE.formatter=PATTERN

# Formatter pattern configuration
formatter.PATTERN=org.jboss.logmanager.formatters.PatternFormatter
formatter.PATTERN.properties=pattern
formatter.PATTERN.pattern=%d{HH:mm:ss,SSS} %-5p [%c] %s%E%n
