Trying to use Preferences in java but need admin rights (need to work on windows and MAC) -


i trying save settings program.

i instance asking user pick folder when program run first time.

this working , wonderfull, not saved.

prefs = preferences.userroot().node(this.getclass().getname());

returns warning: not open/create prefs root node software\javasoft\prefs @ root 0x80000002. windows regcreatekeyex(...) returned error code 5.

error code 5 (access denied)

how ask admin rights? both on windows , mac, thank time!

i found out when using userroot(), program indeed makes key. throws warning because java tries make in systemroot() aswell, incase ever need in systemroot. when using userroot() never will.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
