Question:

I am facing one strange problem , I am working on one batch application using below tech STACK Spring (IOC container) , spring batch , Hibernate , camel and Log4J for logging I have configured log4J for file appender only and my all application logs goes to my log file , but strange thing is that all Camel logs goes to console appender (I have no console apender configured on my log4J properties file)

<strong>Spring – Camel Integration is XMl element :</strong>

<camelContext xmlns="http://camel.apache.org/schema/spring"> <routeBuilder ref="smtBatchRouter" /> </camelContext>

<strong>My Log4J configuration:</strong>

log4j.rootLogger=TRACE, file log4j.logger.org.apache=TRACE log4j.logger.org.directwebremoting=OFF log4j.logger.org.hibernate=OFF log4j.logger.org.springframework=WARN log4j.appender.file=org.apache.log4j.DailyRollingFileAppender log4j.appender.file.file=myapp.log log4j.appender.file.ImmediateFlush=true log4j.appender.file.bufferedIO=false log4j.appender.file.DatePattern='.' dd-MM-yyyy log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%d [%-15.15t] %-5p %-30.30c{1} - %m%n log4j.appender.file.threshold=TRACE

<strong>Sample Camel Log that I am getting in console :</strong>

[main] INFO org.apache.camel.spring.SpringCamelContext - Apache Camel 2.11.0 (CamelContext: camel-1) started in 4.009 seconds [Camel (camel-1) thread #0 - sftp://xyz.com/smtDataFolder] INFO org.apache.camel.component.file.remote.SftpOperations - JSCH -> Connecting to localhost port 22 [Camel (camel-1) thread #0 - sftp://xyz.com/smtDataFolder] INFO org.apache.camel.component.file.remote.SftpOperations - JSCH -> Connection established [Camel (camel-1) thread #0 - sftp://xyz.com/smtDataFolder] INFO org.apache.camel.component.file.remote.SftpOperations - JSCH -> Remote version string: SSH-1.99-OpenSSH_4.6

Have you checked Apache Camel docs - <a href="http://camel.apache.org/how-do-i-use-log4j.html" rel="nofollow">http://camel.apache.org/how-do-i-use-log4j.html</a>

I had the same issue and solved it. Run your application with the flag:<br />-Dlog4j.debug<br /> It will add diagnostic information to your console. In my case it was

SLF4J: Class path contains multiple SLF4J bindings.

So I just deleted redundant slf4j-jdk14-1.7.9.jar and left only slf4j-log4j12-1.7.19.jar.
