How to prevent startup console log info?

[fangzx]

In My Web app startup time, I can see following info in the console:

- Welcome to Seam 2.0.0.GA
- scanning: /D:/workspace-fzx/Divo2/WEB-INF/lib/jboss-seam.jar
- scanning: /D:/workspace-fzx/Divo2/WEB-INF/lib/jboss-seam-remoting.jar
- scanning: /D:/workspace-fzx/Divo2/WEB-INF/lib/jboss-seam-ui.jar
- Namespace: http://jboss.com/products/seam/async, package: org.jboss.seam.async, prefix: org.jboss.seam.async
- Namespace: http://jboss.com/products/seam/framework, package: org.jboss.seam.framework, prefix: org.jboss.seam.core.framework
- Namespace: http://jboss.com/products/seam/theme, package: org.jboss.seam.theme, prefix: org.jboss.seam.theme
more ...

--------------------------
Can I use log4j.xml to turn off above log info?

[appendix]

Just increase the log level for javax.servlet.ServletContextListener (Generic Welcome Message), org.jboss.seam.deployment.* and org.jboss.seam.init.* to WARN or higher.
