After you have restart your tomcat,you should figure out this values for your system: submit the simplest program to get the base memory of each language. for g++ and gcc int main(){} for freepascal begin end. after submit these programs,you can check the memory used by them,and adjust the values stated in LanguageExtMemory. then restart your tomcat(or just reload the JudgeOnline from Tomcat Web Application Manager). Now if you submit the simplest program again,you should see all of them use 0K memory. This process will be done automatically in future version. 4.Administration --the default admin account of JudgeOnline is 'root',and password='rootpass' --admin's main page /JudgeOnline/admin (be sure,there's not a '/' at the end,or you will get error) --you can add/modify problems,add contest... --after add problem ,JudgeOnline will make a new directory using the problem_id as its name in d:\data\; you should copy your test data of this problem to this directory. JudgeOnline support mutiple input and output files. each input and output file's format is stated in the problem's input and output description. Make sure the input and output files name is like *.in *.out ("in" and "out" must in lower case); and the corresponding input and output files must have the same main file name. Take d:\data\1000 for example,it has three input and output files. problem 1000 have 3 pairs of input and output data1.in data1.out data2.in data2.out data3.in data3.out --You can use html tags when you add problem, such as <img ...>. --If you want add images in your problem,just put the image in somewhere accessible from web, and then put the url of image in <img > tag. --If you want rejudge some problem:login as an administrator, access /JudgeOnline/admin.rejudge?problem_id=pid replace pid with the problem_id you want rejudge.You will see a simple page indicating the time when server receive this request. --When you add or modify a problem, if there are any contest scheduled,you can add this problem to the contest by choosing contest in the problem adding or modifying page. --by now administration is too weak, later i will enhance it. 5.Limitation --this is a free version of JudgeOnline and has following limitations: (1).It's not secure enough:it can't permit users from access disk files or other vicious activities such as delete important files. BE CAREFULL ABOUT THIS. (2).Not support special judge. (3).Only have 3 languages in this package (g++,gcc and pascal), especially remove the support of java5.0. Later i will publish new version and also with more detailed help information:) At last ,sorry for my terrible english.
