How are pre-compiled JSPs handled?
As an IBM enhancement to JSP support, IBM WebSphere Application Server provides a batch JSP compiler. Use this function to batch compile your JSP files and thereby enable faster responses to the initial client requests for the JSP files on your production Web server. It is best to batch compile all of the JSP files associated with an application. Batch compiling saves system resources and provides security on the application server by specifying if and/or when the server is to check for a class file or recompile a JSP file. Unless you have configured the web application otherwise, the application server will monitor the compiled JSP file for changes, and will automatically recompile and reload the JSP file whenever the application server detects that the JSP file has changed. Use the JSPBatchCompiler tool. It works for 4.0 AEs. To make it work for beta Advanced Edition code, make a copy of the bat file, and replace org.apache.jasper.compiler.ibmtools.BatchC with org.apache.jasper.compi
