netbeans - java - Sharing an executable .jar file -

-

i wrote program in netbeans, , want share coworker. however, when tries running on computer, gets error message:

"could not find main class: excelcomparator.excelcomparator. program exit."

here's confusing part: wrote on laptop has netbeans, , make sure worked, copied dist folder onto flash drive, , ran on computer. worked fine. when emailed coworker, got error.

based on i've seen, solutions run .jar command line. while might work, need file double-clickable.

i sent coworker file via email in zipped folder, possible unzipping entire folder messed .jar file (don't see why should, included might help)?

this manifest.mf that's within .jar file. there carriage return @ end of file, doesn't copy text box:

manifest-version: 1.0 ant-version: apache ant 1.9.4 created-by: 1.7.0_71-b14 (oracle corporation) class-path: lib/poi-3.12-20150511.jar lib/poi-examples-3.12-20150511.j  ar lib/poi-excelant-3.12-20150511.jar lib/poi-ooxml-3.12-20150511.jar   lib/poi-ooxml-schemas-3.12-20150511.jar lib/poi-scratchpad-3.12-2015  0511.jar x-comment: main-class added automatically build main-class: excelcomparator.excelcomparator

i sent dist folder, includes lib folder contains additional .jars.

if there's other relevant information need include, let me know. thanks!

if want jar double-clickable should bundle dependencies single jar file.

you achieve using maven assembly plugin: http://maven.apache.org/plugins/maven-assembly-plugin/usage.html

if don't know how use maven, eclipse has nice wizard. i'm not sure how works on netbeans same question has been asked many times, e.g. here netbeans export jar, include library files

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
