netbeans & java, resourceMap.getString returning null -

-

product version: netbeans ide 6.8 (build 200912041610) java: 1.6.0_17; java hotspot(tm) client vm 14.3-b01 system: windows 7 version 6.1 running on x86; cp1252; en_gb (nb)

hello, newbee java programmer here , wondering if can help, have been having problems updating gui desktop application in netbeans, here details:

my current application gui works great, appearing correctly.

when update gui adding new label netbeans toolbox onto form, , use netbeans preview function, looks great

however when run application new label has disappeared..

to try , understand problem ran app in debug mode , stepped through auto-generated initcomponents() code

from debugging believe problem comes line of code:

test_lbl.settext(resourcemap.getstring("test_lbl.text")); // noi18n

after line of code has executed test_lbl.settext equal null..

so label disappearing when run app because has no text value display...

i opened resource map file in notepad (the .properties file) , contains entry "test_lbl.text=jlabel1" among entries other working controls...

so properties file has correct value, resourcemap.getstring not retrieving it

i can work around problem changing "automatic resource management" option of form "all resources" "off"

as result changes auto-generated "settext" code line to: 

test_lbl.settext("jlabel1");

and makes label display correctly when application runs

my first question be, known bug? or have done silly , accidently changed setting someware?

if not bug, how correct problem without changing resource management setting?

if bug, implications of turning off automatic resource management?

thanks help, - gaz

i assume you're running under nb (run > run main project)?

try clean build (run > clean , build main project). fix it.

it's issue of how build system structured.

when run project in clean repository (run > run main project):

  1. the .class files written $project/build/classes
  2. the non-class files copied tree
  3. the whole thing run there.

that works fine.

if "build" project (run > build main project): 1. .class files written $project/build/classes 2. non-class files copied tree 3. whole thing rolled jar file.

that works fine.

however, if subsequently make changes , run project, class files , resources appear in 2 places:

  • in build/classes
  • in dist/project.jar

this works ok far finding class files. resources, however, found in jar first. so, @ runtime, code finds outdated copy of properties file in jar, not new 1 in filesystem.

also: nb ignores case when finding resource, sun's jvm not (not sure icedtea). so, if wrong case used nb may insist file there, jvm not able find it.
