Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
Hi Don: For 4.3 do the following: 1) you need to have these jars in your application's classpath: slf4j-log4j12-1.7.5.jar log4j-1.2.17.jar 2) now you need a log4j.xml file, also in your classpath, heres a minimal one: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <log4j:configuration xmlns:log4j='http://jakarta.apache.org/log4j/'> <appender name="applog" class="org.apache.log4j.RollingFileAppender"> <param name="File" value="mylog/app.log"/> <param name="MaxFileSize" value="10MB"/> <param name="MaxBackupIndex" value="10"/> </appender> <root> <level value="WARN"/> <appender-ref ref="applog"/> </root> </log4j:configuration> this would suppress all messages except WARN and ERROR and log those to "mylog/app.log" keeping up to 10 10MB logs. So make your changes as needed. In 4.4 we have switched to log4j2, so the config file is a bit different. Ill try to update the web pages.
