无法启动Warbler可执行文件

Question

我在使用warbler打包JRuby应用程序并运行它时遇到了一些问题。

我已经用一个模型创建了一个简单的sqlite3-app，它在通过jruby -S rails s运行时运行得很好。

但是，如果我尝试用jruby -S warble executable war打包它，打包后的Winstone-server就会崩溃

这是从哪里来的，我如何让它运行？

Answer 1

这是由于Windows1.5.5及更早版本中的一个错误，该错误会影响在JRuby上运行可执行jar和包含空格的路径。参见JRUBY-4774或WARBLER-15。

尝试将JRuby升级到1.5.6 (gem update jruby-jars)，重新构建war文件，然后重试。
