Upgrade to tiles 3 jcl-over-slf4j

Should jcl-over-slf4j be in the tiles-core pom?

It seems to be an option for migrating from Jakarta Commons Logging which
some might not want to do.

<dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>jcl-over-slf4j</artifactId>
</dependency>


http://www.slf4j.org/legacy.html

To ease migration to SLF4J from JCL

#####

I use Jakarta Commons Logging.


slf4j-jcl is used to delegate all SLF4J logging to Commons Logging.

<dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-jcl</artifactId>
</dependency>


and then log4j-jcl to delegate all to Commons Logging to log4j 2

<dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-jcl</artifactId>
            <version>2.5</version>
</dependency>



Cheers Greg.

There is!

Re: Upgrade to tiles 3 jcl-over-slf4j

Posted by Paul Benedict <pb...@apache.org>.

I could be wrong, but I thought log4j2 provides the equivalent bridging
functionality to other logging frameworks.

Cheers,
Paul

Re: Upgrade to tiles 3 jcl-over-slf4j

Posted by Greg Huber <gr...@gmail.com>.

Yes, if you are logging directly to log4j2 but if other jars use slf4j you
need to delegate the logging (create a log4j2.xml if upgrading from v1,
note the format is also different!)


<dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.14</version>
</dependency>
<dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-slf4j-impl</artifactId>
            <version>2.5</version>
</dependency>

Cheers Greg

Re: Upgrade to tiles 3 jcl-over-slf4j

Posted by Greg Huber <gr...@gmail.com>.

I plan to, but not really motivated at the moment as its quite a job
converting all my poorly formatted logging to use the new format.

Cheers Greg

btw does any body know how to get velocity to log correctly to log4j 2?

Hi Greg-

can you confirm these dependencies for log4j?

  <dependencies>    <dependency>      <groupId>org.apache.logging.log4j</groupId>      <artifactId>log4j-api</artifactId>      <version>2.5</version>

Re: Upgrade to tiles 3 jcl-over-slf4j

Posted by Greg Huber <gr...@gmail.com>.

Well, I currently log with commons, but to get struts logging working I
have had to upgrade to v2 and use the log4j2.xml file.

Also a good idea to bypass the commons for slf4j and go directly.

Cheers Greg

I see that it is currently the case but I do not need it.

SLF4J can be forwarded to log4j 2 directly with log4j-slf4j-impl. There is 
no need to include Commons Logging (if you don't need it for other reasons 
than forwarding).

 <dependency>
       <groupId>org.apache.logging.log4j</groupId>
       <artifactId>log4j-slf4j-impl</artifactId>
 </dependency>

Christoph
