log4jResource setting in GBean: ApplicationLog4jConfigurationGBean

[viola.lu]

hi, i follow steps in http://cwiki.apache.org/GMOxDOC22/configuring-application-specific-logging-with-log4j.html, and add gbean information in geronimo-web.xml using log4jResource.

<dep:gbean class="org.apache.geronimo.system.logging.log4j.ApplicationLog4jConfigurationGBean" name="testlogLog4jConfiguration">
     
    <dep:attribute name="log4jResource">META-INF/log4j.properties</dep:attribute>
       
    </dep:gbean>

But "Can't find META-INF/log4j.properties " error always exists. if i use log4jFile setting like below:

<dep:gbean class="org.apache.geronimo.system.logging.log4j.ApplicationLog4jConfigurationGBean" name="testlogLog4jConfiguration">
      <dep:attribute name="log4jFile">var/log/log4j.properties</dep:attribute>
    <dep:reference name="ServerInfo"><dep:name>ServerInfo</dep:name></dep:reference>
    <!--<dep:attribute name="log4jResource">META-INF/log4j.properties</dep:attribute>-->      
    </dep:gbean>

it works well.

I looked into ApplicationLog4jConfigurationGBean code:
...
InputStream in;
        if (log4jFile != null) {
            File file = serverInfo.resolveServer(log4jFile);
            in = new FileInputStream(file);
        } else if (log4jResource != null) {
            in = classloader.getResourceAsStream(log4jResource);
            if (in == null) {
                throw new NullPointerException("No log4j properties resource found at " + log4jResource);
            }
        } else {
            return;
        }

...

in = classloader.getResourceAsStream(log4jResource);

ClassLoader will search this file from classpath, and my project structure is:

LogWeb
    ---src(testlog.java
    ---WebContent
          META-INF(log4j.properties)
          WEB-INF
          index.jsp
    ----

Why it can't find out file META-INF/log4j.properties?

Anyone can figure it out? Thanks.

Because that's not in your classpath.

Try WEB-INF/classes/META-INF/log4j.properties.

Thanks david.

 I moved folder META-INF/log4j.properties to WEB-INF/classes/, and then modify deployment plan with :
<dep:attribute name="log4jResource">META-INF/log4j.properties</dep:attribute>

It works oz it's in the classpath now.

I'm trying to do the same thing, but so far my application didn't have a deployment plan yet. Now I'm trying to add one, so I can add the GBean, but it's still not logging the way I want to. Any idea what I might be doing wrong? (I have of course put the properties file in the specified directory.)

Can you attach your application here and your geronimo server version? thanks.

Try WEB-INF/classes/META-INF/log4j.properties.

Hi Ivpal, looks like the plan is correct.

So as you said "it's still not logging the way I want to."?  we'd like to know what's your expectation?
Can you deploy your application successfully? Can it be started successfully?
Is there any exception shown in geronimo.log file?

Well attaching the whole application might be a bit overwhelming. It's a multi-module Maven project. I'm using an aspectJ library to weave in the logging code into several of my modules. This is working, because I am seeing the logging, only it is logging in geronimo.log and based on my log4j.properties I'm expecting it to log into a logfile of my own.

My Geronimo version is 2.1.4 based on Jetty.

This is my log4j.properties file:

# Set root logger level to DEBUG and its only appender to LOGFILE.
#log4j.rootLogger=INFO, CONSOLE
log4j.logger.nl.lunaris.bookdb=DEBUG, LOGFILE

# CONSOLE is set to be a ConsoleAppender
#log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
#log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
#log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# LOGFILE is set to be a FileAppender.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=C:/Projects/Boekenplank/logs/booklog.txt
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d [%t] %-5p %c - %m%n


I had tried to log everything else to console first, but then I read that I can't use the rootLogger (because Geronimo uses that), so I commented that logger out.

Thank You!!! ;-)

Viola,
I'd really we rather not request attachments (especially potentially  
large attachments) on our mailing lists. Would prefer that we either  
use Jira (Attach file) or other file sharing mechanisms...

Thanks David and Viola.

 The document http://cwiki.apache.org/GMOxDOC22/configuring-application-specific-logging-with-log4j.html has been updated with this issue:


You can also use a log4j.properties file in your classpath, for example, in WEB-INF/classes/META-INF. (If you prefer not to place this file under WEB-INF/classes/, the path of this file must be added to your classpath). But this will obstruct anyone trying to configure logging as the file will remain packed in your application somewhere hard to find.

<gbean name="DirectoryLog4jConfiguration" class="org.apache.geronimo.system.logging.log4j.ApplicationLog4jConfigurationGBean">

<attribute name="log4jResource">META-INF/log4j.properties</attribute>
 </gbean>

it works well.

I looked into ApplicationLog4jConfigurationGBean code:
...
InputStream in;

          File file = serverInfo.resolveServer(log4jFile);
          in = new FileInputStream(file);

              throw new NullPointerException("No log4j properties resource
found at " + log4jResource);
          }
      } else {
          return;
      }

...

in = classloader.getResourceAsStream(log4jResource);

ClassLoader will search this file from classpath, and my project structure
is:

LogWeb
  ---src(testlog.java
  ---WebContent
        META-INF(log4j.properties)
        WEB-INF
        index.jsp
  ----

Why it can't find out file META-INF/log4j.properties?

Because that's not in your classpath.

Try WEB-INF/classes/META-INF/log4j.properties.
