As an addition to Buknin's post /opt is considered as "static" (vs dynamic ) and so any data variable or dynamic files for the application's configuration etc should be played in /var/opt/<app-name>, it has its importance if you have limited time frame for e.g. backups, you know that what is important to you on a daily basis check is in /var/opt for all your applications which should be save with your data...

NAME
jlex - lexical analyser generator for Java(tm) SYNOPSIS
jlex specfile DESCRIPTION
JLex takes the language specification in specfile and generates Java(tm) source code for a lexical analyser corresponding to the specifica- tion. The lexical analyzer source code is placed in a file whose name is the name of the JLex specification file, with the string ".java" added to the end. For example, if the JLex specification file is called foo.lex, the lexical analyzer source code file that JLex produces will be called foo.lex.java.) The resulting lexical analyzer source code should be compiled with a Java compiler. This produces a lexical analyzer class file, which can then be used in your application. If the default settings have not been changed, the lexical analyzer class will be called Yylex and the class files will named Yylex.class and Yytoken.class. For more information, see the JLex manual in /usr/share/doc/jlex/manual.html. SEE ALSO
