Исключение при использовании JWrapper

Question

Я пытаюсь построить exe из jar-файла с помощью jWrapper. Почему я получаю ошибку, как показано ниже, при попытке генерировать exe с помощью JWrapper? Просьба помочь

Answer 1

была такая же проблема. В моем случае это было из JRE, которое НЕ было включено в jwrapper.jar. Я загрузил Windows JRE6 from here (читал где-то, что JRE7 не круто включать?) И скопировал полный каталог jre6 в мой каталог jwrapper. То же самое для linux от here. Windows просто 32bit, Linux 32 и 64 бит.

<!-- Here's where you specify your Windows 32 bit JRE, note that you can use a 32 bit JRE on 64 bit Windows --> 
<Windows32JRE>jre6</Windows32JRE> 
<Windows64JRE>jre6</Windows64JRE> 
<Linux32JRE>jre1.7.0_17_32</Linux32JRE> 
<Linux64JRE>jre1.7.0_17_64</Linux64JRE> 

моя проблема в том, что текущий рабочий каталог не совпадает с размещенным .exe. возможно, я смогу найти решение для этого.
