so i'm trying write first program pulls data web, , since it's financial program, decided use (allegedly) easy , simple yahoo! finance api. downloaded api .jar files, , save, imported whole lot of them eclipse via add external jars tool.
problem is, whenever try run it, socketexception: permission denied runtime error.
the code i'm running incredibly basic:
stock stock = yahoofinance.get("orcl"); that 1 line of code should value of oracle (orcl) stock yahoo finance. instead throws exception.
i have tried can think of:
1) disabled firewalls 2) double checked .jar imports 3) tested running line part of separate thread (a desperate, blind move reaching @ point).
i have exhausted every possible angle of research can think of, , i've found far this: sending email using jsp
this looks similar problem, attempted solution suggested: adding line "-djava.net.preferipv4stack=true" eclipse.ini file. seems have had no effect.
just in case, i'm pasting contents of eclipse.ini file here too, in case put in wrong spot or something:
-startup plugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar --launcher.library plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20140603-1326 -product org.eclipse.epp.package.standard.product --launcher.defaultaction openfile --launcher.xxmaxpermsize 256m -showsplash org.eclipse.platform --launcher.xxmaxpermsize 256m --launcher.defaultaction openfile --launcher.appendvmargs -vmargs -djava.net.preferipv4stack=true -dosgi.requiredjavaversion=1.7 -xms40m -xmx512m i'm out of ideas right now. want know why exception being thrown, , can prevent it.
thanks in advance.
edit: request, full stack trace.

i think i'm having same problem: takes little bit hard, managed information wanted being little bit boring, mean, recursively:
void searchquote(symbol) throws interruptedexception { try{ stock stock = yahoofinance.get(symbol); }catch(exception e){ if(e.getclass().getname().equals("java.net.socketexception") || e.getclass().getname().equals("java.net.sockettimeoutexception")){ thread.sleep(60000); searchquote(symbol); } } } for me, worked.
