Ant task to run the jsp compiler. +
-
This task takes the given jsp files and compiles them into java files. It -is then up to the user to compile the java files into classes. +It can be used to precompile jsp pages for fast initial invocation +of JSP pages, deployment on a server without the full JDK installed, +or simply to syntax check the pages without deploying them. +In most cases, a javac task is usually the next stage in the build process. +The task does basic dependency checking to prevent unnecessary recompilation -this +checking compares source and destination timestamps, and does not factor +in class or taglib dependencies. + +
+ +The task needs jasper.jar and jasper-runtime.jar, which come with +builds of Tomcat 4/Catalina from the +Jakarta Tomcat project + + +
