CSS configuration
by Benoit Xhenseval 09 Feb '11

09 Feb '11

Hi * Our flagship product has been using SLF4J for years but we're switching to LogBack and so far...loving it! We have a question about the CSS builder we could be using for HTML emails. We noticed the DefaultCssBuilder and the UrlCssBuilder, however is there a way to either include the CSS in a jar file, or to specify the CSS in the XML file directly? Something like: <cssBuilder class="ch.qos.logback.classic.html.ExplicitCssBuilder">  <cssText> ...the CSS Text itself.... </cssText> </cssBuilder> Is it something that exists or something that somebody would be willing to provide code or guidelines?

LOGback XML configuration schema
by Grzegorz Szpetkowski 09 Feb '11

09 Feb '11

Could you provide XML Schema (XSD) for XML configuration files ? In Eclipse there is smart code completion for XML files associated with XSD, I found for Log4j there is DTD: http://wiki.apache.org/logging-log4j/Log4jXmlFormat I found some discussion here: http://www.mail-archive.com/logback-user@qos.ch/msg00055.html "There is no DTD to logback configuration files because this is pretty difficult to give a description that is not too strict of the possibilities that the components of logback may offer. " Actually DTD is very primitive, I think that XSD is much more appreciate way. I prepared XSD for Open Street Map (http://forum.openstreetmap.org/viewtopic.php?id=7186) please let me know if you interested in my any help. Regards, Grzegorz Szpetkowski

Help with logback configuration
by jaybytez 09 Feb '11

09 Feb '11

Thanks for your help...I just switched from log4j to slf4j/logback and this is one issue holding us up from moving to QA/UAT...so I am on a fire drill. If what I have here is not the right way to think about logging for my scenario...please let me know. I have multiple variations I have tried, but I will list the two here. WLS 11g, in my war [SLF4J 1.6.1 api/ext, Logback 0.9.27 core/classic, log4j-over-slf4j 1.6.1, jcl-over-slf4j 1.6.1] I have multiple wars that run in 1+ managed instances of WLS that write to the same central log files. Trying to have one central log and each application have their individual log files (but one across the managed instances...unless it's easier for each managed instance to have its own copy). 1) I included slf4j/logback jars in WLS lib directory and add one logback.xml file into the main/resources directory so when the war is built it gets put into WEB-INF/classes of the war. - No log files are produced at all, not even writing a 0 byte file. 2) I included slf4j/logback in a preclasspath folder that I add into WLS startup scripts and I also added -Dlogback.configurationFile=%DOMAIN_HOME%\lib\logback.xml into the startup script. I excluded a configuration file from the war. - Log files are created, but nothing is printed to any of the log files. Here is my config: <configuration> <appender name="sc-resources.log" class="ch.qos.logback.core.rolling.RollingFileAppender"> <prudent>true</prudent> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  <fileNamePattern>./logs/sc-resources.%d{yyyy-MM-dd}.log</fileNamePattern>  <maxHistory>30</maxHistory> </rollingPolicy> <encoder> <pattern>%d [%thread] %level %logger - %m%n</pattern> </encoder> </appender> <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d [%thread] %level %logger - %m%n</pattern> </encoder> </appender> <logger name="com.foo.service.mem" level="trace"> <appender-ref ref="MemberSearchBusinessService" /> </logger> <appender name="MemberBusinessService" class="ch.qos.logback.core.rolling.RollingFileAppender"> <prudent>true</prudent> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">  <fileNamePattern>./logs/MemberBusinessService%d{yyyy-MM-dd}.log</fileNamePattern>  <maxHistory>30</maxHistory> </rollingPolicy> <encoder> <pattern>%d [%thread] %level %logger - %m%n</pattern> </encoder> </appender> <logger name="com.foo.service.mem" level="trace"> <appender-ref ref="MemberBusinessService" /> </logger> <logger name="org.apache.cxf" level="debug"> <appender-ref ref="sc-resources.log" /> </logger> <logger name="org.hibernate" level="warn"> <appender-ref ref="sc-resources.log" /> </logger> <logger name="org.quartz" level="warn"> <appender-ref ref="sc-resources.log" /> </logger> <logger name="org.springframework" level="warn"> <appender-ref ref="sc-resources.log" /> </logger> <root level="trace"> <appender-ref ref="stdout" /> <appender-ref ref="sc-resources.log"/> </root> </configuration> Thanks for your help....jay -- View this message in context: http://old.nabble.com/Help-with-logback-configuration-tp30846851p30846851.h… Sent from the Logback User mailing list archive at Nabble.com.

Autoscan logback configuration using Glassfish V 3.0.1
by cinhtau 09 Feb '11

09 Feb '11

Dear users, based on http://hwellmann.blogspot.com/2010/12/glassfish-logging-with-slf4j-part-2.h… this blog I manage to use logback with Glassfish V 3.0.1. I created a simple web application to test the logback features. I use logback.xml and add the scan parameters. <configuration scan="true" scanPeriod="30 seconds"> ... </configuration> If I modify the contents, e. g. change LEVEL from ERROR to INFO, there is no automatic reloading. If I restart the web application, the changes applied. Did anybody manage to solve this with Glassfish V 3.0.1 or could point me to the right direction? Thanks in advance. -- View this message in context: http://old.nabble.com/Autoscan-logback-configuration-using-Glassfish-V-3.0.… Sent from the Logback User mailing list archive at Nabble.com.

Log4j to Logback migration, logback.xml question
by Fabio Erculiani 09 Feb '11

09 Feb '11

Hi there, I'm migrating my stuff from log4j to logback and I've gotten to the log4j.xml -> logback.xml porting. Besides not having a .dtd makes the work quite hard, I am trying to understand one thing: In log4j I had <category> supporting the class= attribute (while <logger>, which would be its replacement from my understanding, doesn't). Is there anything similar in logback.xml? I wrote a custom Logger (implementing Logger interface) and I would like to tell the logger to use it instead of org.slf4j.Logger. Thanks a lot. -- Fabio Erculiani

Using conditional processing
by Michael C Rosenstein 04 Feb '11

04 Feb '11

Hello, I've been experimenting with logback core/classic 0.9.27 (and slf4j 1.6.1) with Tomcat 6.0.29, Java 1.6 on Solaris for the past couple days, and have hit a wall viz conditional configuration processing. When I include a conditional like the following in my configuration file, nothing in the file is processed beginning with and after that directive: <if condition='property("HOSTNAME").contains("hactar")'> <then> <property name="foo" value="bar"/> </then> </if> Even a conditional as simple as the following causes processing to abort: <if condition='"foo".equals("foo")'> <then> <property name="foo" value="bar"/> </then> </if> No errors seen in the ViewStatusMessagesServlet. Am I doing something wrong? Thanks. /mcr

SyslogAppender not logging Throwable message
by Gustav Karlsson 04 Feb '11

04 Feb '11

Hi, We are using the SyslogAppender in logback 0.9.27 and are having an issue with the logging of Throwables. When we are logging an entry like LOG.debug("My message", throwable), "My message" and the throwable's stacktrace is appended to the log, but not the throwable's message. Has anyone else experienced this and know the cause? Regards, Gustav

MDC and env-entry
by José Juan Montiel 04 Feb '11

04 Feb '11

Hi, again with another question. With aspectj, in injecting a var in MCD, something like this... MDC.put("code",var); in some places, depending something, and i'm using this to generate a diferent file for this something like <appender name="APPENDER" class="ch.qos.logback.classic.sift.SiftingAppender"> <filter class="ch.qos.logback.core.filter.EvaluatorFilter"> <evaluator class="ch.qos.logback.classic.boolex.JaninoEventEvaluator"> <expression> (marker != null) && ( (marker.contains("ASPECTJ")) || (marker.contains("SOAP"))) </expression> </evaluator> <onMatch>DENY</onMatch> </filter> <discriminator> <Key>code</Key> <DefaultValue>0000</DefaultValue> </discriminator> <sift> <appender name="FILE-${code}" class="ch.qos.logback.core.rolling.RollingFileAppender"> <prudent>${prudent}</prudent>  <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <Pattern>%date - [%thread] - %.-20M - %L - cn=%contextName - [%thread] - [%X{code}] - %message%n %exception{5}</Pattern> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>${USER_HOME}/${backupDir}${code}.%d${patronRolling}</FileNamePattern> <MaxHistory>${maxHistory}</MaxHistory> </rollingPolicy> </appender> </sift> </appender> ASPECTJ and SOAP are Markers of other traces, that i don't want to see here. This way i get in my root log directory ${USER_HOME}/${backupDir} files like 0001.log 0002.log But, now i have multile apps (wars and ejbs) where i use web.xml <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns=" http://java.sun.com/xml/ns/javaee" xmlns:web=" http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> ... <env-entry> <description>JNDI logging context for this app</description> <env-entry-name>logback/context-name</env-entry-name> <env-entry-type>java.lang.String</env-entry-type> <env-entry-value>APP1</env-entry-value> </env-entry> <env-entry> <description>URL for configuring logback context</description> <env-entry-name>logback/configuration-resource</env-entry-name> <env-entry-type>java.lang.String</env-entry-type> <env-entry-value>logback.xml</env-entry-value> </env-entry> ... </web-app> ejb-jar.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 2.0//EN" "http://java.sun.com/dtd/ejb-jar_2_0.dtd"> <ejb-jar> <enterprise-beans> <session> ... <env-entry> <description>JNDI logging context for this app</description> <env-entry-name>logback/context-name</env-entry-name> <env-entry-type>java.lang.String</env-entry-type> <env-entry-value>EJB1</env-entry-value> </env-entry> <env-entry> <description>URL for configuring logback context</description> <env-entry-name>logback/configuration-resource</env-entry-name> <env-entry-type>java.lang.String</env-entry-type> <env-entry-value>logback.xml</env-entry-value> </env-entry> ... </session> </enterprise-beans> ... </ejb-jar> a env-entry to identificate. I know that insede file, i use cn=%contextName to see this context but... How could i use this context like i use ${code} to separete this files (0001.log, 0002.log) in diferents directories.

Hi, i'm implementing a loggin via AspectJ in a Maven project. My aspect class is something like this... public aspect TraceMethodCalls { static Marker ASPECTJ_TRACE_ENTER = MarkerFactory.getMarker("ASPECTJ_TRACE_ENTER"); final Logger logger = LoggerFactory.getLogger(TraceMethodCalls.class); TraceMethodCalls() { } pointcut traceMethods() //give me all method calls of every class with every visibility : (execution(* *.*(..)) //give me also constructor calls || execution(*.new(..))) && !execution(* toString(..)) && !execution(* hashCode(..)) //stop recursion don't get method calls in this aspect class itself && !within(TraceMethodCalls); //advice before: do something before method is really executed before() : traceMethods() { if (logger.isDebugEnabled()) { //get info about captured method and log it Signature sig = thisJoinPointStaticPart.getSignature(); logger.trace(ASPECTJ_TRACE_ENTER, "---> [" + sig.toShortString() + "]"); } } //advice before: do something before method is really executed after() returning (Object o): traceMethods() { if (logger.isDebugEnabled()) { //get info about captured method and log it Signature sig = thisJoinPointStaticPart.getSignature(); logger.trace(ASPECTJ_TRACE_ENTER, "<--- [" + sig.toShortString() + "]"); } } and logback appender <appender name="ASPECTJ_TRACE_ENTER" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="ch.qos.logback.core.filter.EvaluatorFilter"> <evaluator class="ch.qos.logback.classic.boolex.JaninoEventEvaluator"> <expression> (marker != null) && (marker.contains("ASPECTJ_TRACE_ENTER")) </expression> </evaluator> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <prudent>${prudent}</prudent>  <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder"> <Pattern>%date %-5level - cn=%contextName - [%thread] - %message%n</Pattern> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>${USER_HOME}/${backupDir}aspectj.enter_exit.%d${patronRolling}</FileNamePattern> <MaxHistory>${maxHistory}</MaxHistory> </rollingPolicy> </appender> I see that that support to NDC is disabled in logback, how could i implement a TAB of this messages without NCD? --->Method1 ------>Method2 --------->Method3 <---------Method3 <------Method2 <---Method1 Thanks. -- Jose Juan Montiel Martinez Eurobits Technologies Calle Musgo 3, 1ª Planta 28023 Madrid T +34-917080300 F +34-913077480 josejuan.montiel(a)eurobits.es http://www.eurobits.com

Logback with WebLogic Server - Suggestions
by jaybytez 03 Feb '11

03 Feb '11

I am totally new to SLF4J/Logback, and I am using WebLogic Server 11. We previously were using log4j and used an external file and some custom class so that we could update the log4j file at runtime and not have to reboot the server or application. We didn't use the WebLogic Server console to change the logging level. So if I want to use slf4j/logback, is there anything special I have to do for placing jars in the bootclasspath or lib directory. As well as when I want to have runtime changes to the log level, what is the best way to do this with slf4j/logback and WebLogic Server? I read this blog for help: http://blog.kares.org/2009/10/log4j-logging-without-log4j.html Thanks for your help...jay -- View this message in context: http://old.nabble.com/Logback-with-WebLogic-Server---Suggestions-tp30829362… Sent from the Logback User mailing list archive at Nabble.com.
