tapestry5.1 怎么把log4j 更换为 logback，更换后就出错。
exception javax.servlet.ServletException: PWC1243: Filter execution threw an exception root cause java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory |

问题解决。解决方法：删除tapestry 5.1自带的slf4j-log4j12-1.5.2.jar和log4j-1.2.14.jar，添加logback-core-0.9.17.jar和logback-classic-0.9.17.jar，在WEB-INF\classes下加上logback.xml配置文件即可，slf4j原生支持logback。
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>logs/web.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>logs/web.%d{yyyy-MM-dd}.log.zip</fileNamePattern>
</rollingPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%-20(%d{HH:mm:ss.SSS} [%thread]) %-5level %logger{80} - %msg%n</pattern>
</layout>
</appender>
<root level="WARN">
<appender-ref ref="file" />
</root>
</configuration>
