We are developing a software in Java to conduct an online test.We have used three files ,the first is the "question_bank" containing 1500 questions having 500 questions each in C,Computer fundamentals and analytical reasoning .The second file is "question_paper"that is created at runtime by selecting 90 questions(30 each)from the first file ,the third file keeps records of all candidates who have attennded the online exam.
Ourproblem is that we are unable to read or save record to a local file using the applet.In order to do that we follow the following three approaches
We made changes in the default polic file ie: java.policy
We made a new security policy and call the applet with the new security policy in effect.
We specified a number of URLs in policy .URL.n properties in the security proiperty file(java.security) to get all the designated policy files created.
None of the above approaches have worked .Can anybody help us?
