YUZU requires JDK 1.4. To compile YUZU for JSP 1.2 (tomcat 4.x), edit "build.xml" for your environment, and run "ant" in "jsp12" subdirectory. To compile YUZU for JSP 2.0 (tomcat 5.x), edit "build.xml" for your environment, and run "ant" in "jsp20" subdirectory. By default, the name of the build target file is "yuzu.jar". You can place a file named "build.properties" here or in each subdirectory (jsp12/jsp20) with a line "jarfile=XXX" to override the default. HTML/MIME parsers are written using JavaCC ("https://javacc.dev.java.net/"). If you need to modify the parser, you need to install JavaCC and compile the following files: src/common/com/micronova/util/cc/html/Parser.jj src/common/com/micronova/util/cc/mime/Parser.jj src/common/com/micronova/util/cc/json/Parser.jj
