Re: log4j in two different project
Hi Is there any help I can get in this? * Are you log4j.properties files for each project identical? o No * the config file for you webapp doesn't provide the configuration you require for your DAO o How to do this? What does this mean? * is the DAO project deployed in WEB-INF/lib o What does this mean? how I can check?

That is, is it part of the same classloader as the webapp. That could be an issue as well if it is not.

What does this mean? Because your DAO project (jar file) runs within the context of your webaapp and Log4j provides only a single configuration context per webapp (assuming Log4j.jar is deployed in WEB-INF/lib and you are using child-first classloading), then you need your config file to encompass the configuration for all applicable libraries. In this sense, you shouldn't think of your DAO project as something separate from the webapp. It's really a library dependency of the webapp, making it, for all intents and purposes, part of a single application. * is the DAO project deployed in WEB-INF/lib o What does this mean? how I can check? I presume your DAO project is represented as a jar file, no? If you use it as part of your webapp, then it must a library dependency of the webapp. If it is a library dependency of your webapp, then you normally deploy this in WEB-INF/lib. I'll leave it at that. Jake Thanks, Anjib On 1/9/2012 4:37 PM, Jacob Kjome wrote: Are you log4j.properties files for each project identical?

Re: Log4j and Java7/JDBC4.1's CommonDataSource.getParentLogger()
I have hit the same situation with software that requires use of Apahce commons logging, I use slf4j (and have it feed log4j); it has adapters to let you log from j.u.l and commons logging. I don't know if it's best practice, but it certainly works. ■ DOUGLAS E.

RE: Log4j and Java7/JDBC4.1's CommonDataSource.getParentLogger()
I am not following. I already have slf4j in my stack (needed by other libraries), although I've written no code that directly interacts with it. I assume that you are telling me to implement getParentLogger() in my datasource (so that it compiles in Java7) and that I should put a couple lines of code based on slf4j to get that parent logger so that it really is reflecting the log4j logger.

RE: Log4j and Java7/JDBC4.1's CommonDataSource.getParentLogger()
see http://www.slf4j.org/legacy.html you are looking for SLF4J bound to log4j with redirection of commons-logging and jul calls to SLF4J. See the section on jul-to-slf4j bridge, and the reference to SLF4JBridgeHandler javadocs. I would ask on one of the SLF4J groups for more details, if needed. ■ DOUGLAS E.
