what is wrong with log analyser

[ashu bhardwaj]

when i try to open any log file other than activity.log my log analyser tool gives IOException regarding the file format is not valid. i want to view stderr and stdout logs in some better tool than a text editor.how these files can be opened in a log analyser

Today, I used Java Console. From this console, I started log analyzer and found a similar problem. Invalid log format problem. Does somebody know this?
