JSP 预编译工具

　　---------------------------------------------------
　　Post Server Startup JSP File Compiler and Validator
　　---------------------------------------------------
　　This utility helps to
　　1. Simulate a precompilation of jsp's after the server has already started up.
　　This way, we do not have to wait for all the jsp's to be precompiled before starting up the server.
　　2. Test the validity of all the jsp's. If any jsp does not compile, a response code of 500 is returned. The tool lists that jsp, so it can be worked on.
　　
　　The list of jsp targets to be precompiled must be supplied in a plain text file.
　　
　　A sample is below:
　　#---------------------------------------------
　　/console/index.jsp
　　/console/standards/home.jsp
　　#---------------------------------------------
　　
　　All the targets defined in there a hit sequentially, the response code monitored and such information relayed to the user.
　　
　　Usage:
　　java TestJSPFiles <fName>
　　
　　If you specify no parameters, this help will be displayed
　　At least one parameter, the fileName should be specified
　　
　　Below simulates the default argument list (if no parameters are passed in)jsp-pages.txt
　　
　　If form based authentication is required, then send the username and parameters
　　
　　System Properties, passed using the -D flag, are used to set the argument
　　list. They are listed below:
　　host the hostname or ip address of the machine port the port the server is listening on
　　debug If true, extra information like the actual output string is written to std error stream
　　If authentication is required to view some of the pages, the following will be required.
　　username The username to login as
　　password The password for that user formauthtarget The j_security_check target. By default, it is/j_security_check. It can be specified as the login page may vary.
　　
　　Sample Usage is below:
　　java -Ddebug=false -Dhost=localhost -Dport=7701 -Dusername=system -Dpassword=system_password -Dformauthtarget=/console/login/j_security_check TestJSPFiles jsp-pages.txt
　　
　　At the end, we tell you how many pages were OK (returned 200)
　　and how many were broken (including list of broken pages).
　　This will help you know which pages are broken immediately.
　　
　　Any pages already precompiled will not precompile again.
　　Thus, there is no performance hit on running this script multiple times.
　　
　　**** NOTE ****
　　The file passed should have the full path of pages to precompile
　　Example Scenario:
　　webapp context-path is /console
　　to precompile the jsp pages, index.jsp and standards/home.jsp in there
　　File should be as below
　　#---------------------------------------------
　　/console/index.jsp
　　/console/standards/home.jsp
