java - Is it acceptable to globally and finally store the check for a SecurityManager -

-

is acceptable globally , store check security manager?

given following line of code:

public static final boolean sec_on = (system.getsecuritymanager() != null);

would acceptable place in library , reuse result throughout lifetime of jvm?

why? or why not?

[update] similar code exists in reference implementation of java ee - jsp specification. app server/servlet container uses not support dynamic configuration of securitymanager.

no. security manager can installed @ time if not present initially.

c++ - NetBeans Remote Development with additional configuration -

-
i'm trying use netbeans (7.3.1) work on remote project. my configuration following: my local machine windows 7 laptop. doesn't have tools. in particular neither compiler nor debugger. have netbeans ide , putty example. source code, make scripts , (eventually) build results located on remote storage shared across servers , "locals". (i might switch single server storage faster don't think matters @ all.) i'm accessing using sshfs manager . sshfs manager takes server name, path on server, user name , ssh private key. in result mounts directory on server disk on windows. works fine. (although directories, possibly links, represented files in windows explorer, don't know if matters...) netbeans project located on local machine don't think matters , place remotely well. prefer keep "off source" don't have add ignores version control. in netbeans did procedure described in remote developement tutorial . seems successful. netbeans c...
