[jira] [Commented] (OPENEJB-1408) Allow another logging framework to be used

["Michael Glauche (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENEJB-1408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13014494#comment-13014494 ] 

Michael Glauche commented on OPENEJB-1408:
------------------------------------------

The attached patch provides a slf4j logging facility. To use it you'll need slf4-api in your classpath and add a line like this before the openejb server is started:

	System.setProperty("openejb.log.factory", "org.apache.openejb.util.Slf4jLogStreamFactory");

To exclude other logging frameworks needed by openejb or its dependencies i'm using the following with maven2:

		<dependency>
			<groupId>org.apache.openejb</groupId>
			<artifactId>openejb-core</artifactId>
			<version>3.1.4</version>
			<scope>test</scope>
			<!-- exclude logging libraries -->
				<exclusions>
					<exclusion>
						<groupId>commons-logging</groupId>
						<artifactId>commons-logging</artifactId>
					</exclusion>
					<exclusion>
						<groupId>log4j</groupId>
						<artifactId>log4j</artifactId>
					</exclusion>
				</exclusions>
		</dependency>

> Would be nice not to force a logging framework.  
> OpenEJB drags log4j into a project which causes issues.
> If OpenEJB stuck to "Public" Log4J API, it would be possible to switch logging implementations using SLF4J & Wrappers.
> Currently:
> There is a HardCoded dependency on: org.apache.log4j.Layout
> Caused by org.apache.log4j.Layout
