when running jar file created maven project such:

java -jar basictool.jar

i error exception:

i created jar file using maven jar creation wizard: right-click on project, select export > java > runnable jar file options

launch configuration: basictool - work

export destination: c:\users\victor\documents\basictool.jar

library handling: package required libraries generated jar

the version.properties file kept inside of src/main/resources, com/kit/version.properties.

i have checked version.properties file found inside of jar file running:

jar tf basictool.jar > output.txt

where find version.properties file such:

resources/com/kit/version.properties

i attempt load resource this:

resourcebundle.getbundle("com/kit/version");

my machine , environment specifications followed: windows 7, spring version: 3.7.2.

note: found many questions similar 1 have, answers have found point properties file being named or placed in correct location. answers learned version.properties fine, since resourcebundle.getbundle("com/kit/version") first version.class version.properties default. version_en_us.properties before looking base name version.properties. seem in line above, since file version.properties in correct location , named correctly. seem in line other answers have offered :(

i point out finds resource fine when run program spring, brings me suspect jar's creation process cause of problem.

and important note properties file in maven project.

i hope offered enough/clear details. appreciated, thank in advance!

if application calls resourcebundle.getbundle("com/kit/version"); in eclipse works fine.

but when create jar file in way described (export -> java -> runnable jar), version.properties placed within jar file @ resources/com/kit/version.properties. mind "resources" in front of path.
if call jar java -jar basictool.jar outside eclipse version.properties cannot found , java.util.missingresourceexceptionis thrown.

if change path , call resourcebundle.getbundle("resources/com/kit/version"); won't work within eclipse java -jar basictool.jar do.

it seems exporting project eclipse causes problem.

i suggest create jar file use without eclipse maven-assembly-plugin.
example can found here. plugin creates jar file without resources directory , call of resourcebundle.getbundle("com/kit/version"); works within and outside of eclipse.

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
