security - Cannot launch applet using Java 7u21 -


so installed java 7u21 release supposed tighten security applets. unfortunately tightened our applet not run anymore. not good.

the interesting thing stopped working while operate jws. if launch standard applet standard web page works fine.

in jws mode security issues on @ least reflection , java.lang.thread.setdefaultuncaughtexceptionhandler.

the certificates ok.

the release notes oracle not provide input on related jws.

my question community hence: have idea or (even better) solution this?

additional info related given suggestions/comments:

this applet run hundreds of third-party clients worldwide changing security policy unfortunately not option. issue reproducible clients. can confirm changing policy file resolves issue.

when run applet tomcat launched eclipse (thereby of course not having signed applet) brings warning notification in browser expected. being gullible person allow applet run since launched own dev environment. still causes security failure.

i have contemplated if bug in java want see if there else seeing same issue. think know oracle turnaround time fixing bugs not best...

thanks input.

thanks lot tony, suggestion me able create applets in 7u21, propperly; considered forward step fact signing , waking many applets yet on browsers, these on 7u21. culdn't today earlier. trapped since hours, in fact have not reached wake first third party applet legacy app have (i.e. working fine in jvm 1.6 or older).

the applets involved, signed them, error: securityexception - "bad applet class name". have applets, , html code calling them, problem first applet in chain (neither other in invoke chain) might not behave other signed applet doing propperly (these applets java web site training), 3th party applet simple not run , throw de exception above mentioned. thrid part applet dont know internally. sorry might asking particullar case no easy solve without source code, however, please trust tell me idea no matter wich is.

best regards

here page explains it.

oracle code on mixed code

what need take of jars new trustedlibrary line in manifest file. me meant recompile of older code. unjar current jars , rejar including trustedlibrary line.

you must sign of code. not applet. means if have 3 jars code in 3 jars must signed also.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
