Hello, I have recently been having issues with this myself. What you need to do is set the environment variable FOP_OPTS to set the location of the log4j configuration file. In linux, on the command line you would type:
export FOP_OPTS="-Dlog4j.configuration=file:///<location of log4j xml file>" In windows, I think you: 1) Right click My Computer 2) Advanced Settings 3) Environment Variables button 4) Add the variable FOP_OPTS and give it the value "-Dlog4j.configuration=file:///<location of log4j xml file>" 5) Remember to close and re-open the prompt for the changes to take effect. I have my log4j.xml file located in the base fop directory and configured like the following: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE log4j:configuration PUBLIC "-//LOGGER" "http://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/xml/doc-files/log4j.dtd";> <log4j:configuration> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <layout class="org.apache.log4j.PatternLayout"></layout> </appender> <appender name="logfile" class="org.apache.log4j.FileAppender"> <param name="file" value="myFile.log" /> <layout class="org.apache.log4j.PatternLayout"></layout> </appender> <logger name="org.apache.fop"> <level value="warn"/> <appender-ref ref="console" /> </logger> <logger name="org.apache.xmlgraphics"> <level value="warn"/> <appender-ref ref="console" /> </logger> <!-- Any specific class log requests e.g. <logger name="org.apache.fop.pdf.AbstractPDFStream"> <level value="debug"/> <appender-ref ref="logfile" /> </logger> ... --> <!-- ALL | DEBUG | INFO | WARN | ERROR | FATAL | OFF --> <root> <priority value ="debug" /> <appender-ref ref="console" /> <appender-ref ref="logfile" /> </root> </log4j:configuration> Then you simply run FOP and it should output the logging from the classes you specified to the file. Alternatively, change the org.apache.fop / xmlgraphics to the desired logging level and watch it output to the console. If you are still having issues, please post your full log4j.xml file with any reply.
