log4j

问题 I created a simple web application and added log4J's jar in my lib folder and it seems to work fine. Then i created a Ejb module and did the same thing of adding jar file in my classpath, but i am getting this error :- Caused by: javax.ejb.TransactionRolledbackLocalException: Exception thrown from bean: java.lang.NoClassDefFoundError: org/apache/log4j/Logger at com.sun.ejb.containers.BaseContainer.checkExceptionClientTx(BaseContainer.java:4929) at com.sun.ejb.containers.BaseContainer

问题 This is my log4j.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="true"> <appender name="FILE" class="org.apache.log4j.DailyRollingFileAppender"> <param name="File" value="${catalina.base}/logs/server.log" /> <param name="Append" value="true" /> <param name="Threshold" value="INFO" /> <param name="DatePattern" value="'.'yyyy-MM-dd" /> <layout class="org.apache.log4j

问题 I am trying to produce a proof of concept shipping logging from Log4J through JMS using the log4J JMSAppender. I have tried ActiveMQ and the example supplied with it. I have torn this example apart, and made it more generic and compatible with multiple platforms. It looks like I have it all plumbed up OK as I can see a connection to the ActiveMQ happening, but the code hangs when I get the InitialContext ( with -Dlog4j.debug set the ActiveMQ client classes seem to invoke log4J and load the

问题 I try to store all the logs at sentry instance. Accordingly to this thread I tried the following: Added sentry appender to loggin.yml: es.logger.level: INFO rootLogger: ${es.logger.level}, console, sentry ... appender: console: type: console layout: type: consolePattern conversionPattern: "[%d{ISO8601}][%-5p][%-25c] %m%n" sentry: type: net.kencochrane.raven.log4j.SentryAppender dsn: "http://...@..." And copied raven-5.0.jar , raven-log4j-5.0.jar and raven-logback-5.0.jar to es/lib folder. No

问题 When our application throws errors that we catch, we put the message and stacktrace in a log file created specifically for our application (myapp.log). For example: public class SomeClass { OurLogger log = OurLogger.getLogger ("myapp", SomeClass.class); public void someMethod { try { //code } catch (DataAccessException e) { log.error(e.getMessage(), e); } } } We do this because since we are in a environment where multiple apps reside on an application server...ours and every other

问题 I have been looking over these three sites on how to create a map lookup (or any other lookup for that matter) using log4j2: http://logging.apache.org/log4j/2.x/manual/extending.html#Lookups http://logging.apache.org/log4j/2.x/manual/lookups.html http://logging.apache.org/log4j/2.x/manual/configuration.html#PropertySubstitution I understand the general idea behind what I am reading, I am just having a difficult time putting all the bits and pieces together. Goal To be able to place a variable

问题 Configuring log4j I can use the log4j 1.2 pattern %l to give me location of the caller, which outputs: ... com.example.FooBar.doSomething(FooBar.java:123) ... I'm trying to switch to Logger because it is "intended as a successor" to log4j and has all sorts of improvements over log4j 1.2 But Logback has no %l pattern. The closest Logback pattern I can find is %caller{1} , but that gives me something ugly: ... Caller+0 at com.example.FooBar.doSomething(FooBar.java:123) ... Notice that, adding

问题 I'm trying to set up log4j in my app and one of my third party JARs seems to somehow keep turning my log level to "OFF". It only happens when code from that library is executed. I don't know how it can do this because I'm not using a logger it knows the name of, and I'm not using the root logger. I've spent 5 hours on this and so far my only achievement has been to acquire a frustration level of over 9000. I'm using the latest Tomcat (7.0.37) on windows 7 64 bit, Java 6 u23. log4j.properties:

问题 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) Spring – Camel Integration is XMl element : <camelContext xmlns="http://camel.apache.org

问题 I have a class named TraceNoGenerator that works like a Sequence in an Oracle Database; I want to use this class to assign a trace number for each request that comes to my web application to log in a log file. When my application received an error, this trace number will display on a web page so that I can easily find the bug using this trace number in the log file. How can I do this in Log4j? 来源： https://stackoverflow.com/questions/7089241/log-traceno-for-each-request-in-web-application
