netbeans - Error "main.java.lang.IndexOutOfBoundsException: Index: 0, size: 0" and others in Jar file -

let me describe project first.i have source code in java programming language (not programmed me , it's in netbeans ide) .this programme has 4 classes chksubmission.class , parameters.class , plib.class , final relation.class .the programme accepts input dataset folder named "data" contains .zip files , each 1 of .zip files has c++ source codes.then makes complicated compares , extracts results in .txt file name clustering.txt within folder "results" .the programme passes success clean , build progress , got jar file want phone call in html <object></object> tag.i test programme double click , in command line , produced results expected.but after phone call in html didn't produce anything, , if seek run double click doesn't work.if seek run in command line these errors.are parameters ok run applet?please help me .i got confused.the errors are:

exception in thread main.java.lang.indexoutofboundsexception: index:0 size:0 @ java.util.arraylist.rangecheck<unknown source> @ java.util.arraylist.get<unknown source> @ gr.edu.teikav.lmous.research.deltatbl.max <deltatbl.java:37> @ gr.edu.teikav.lmous.research.acf.clust<acf.clust <acf.java:80> @ gr.edu.teikav.lmous.research.chksubmission.submit <chksubmission.java:113> @ gr.edu.teikav.lmous.research.chksubmission.main <chksubmission.java:122>

so runs applet? applet signed? if no, run in sandbox, , cannot access user files.

heres short peek: http://docs.oracle.com/javase/tutorial/deployment/applet/security.html
