配置Launch4J只使用32位JVM [英] Configure Launch4J to use 32-bit JVM only

问题描述

我用Launch4J开始我的Java应用程序，如果一个64位JRE是present系统上，Launch4J似乎preFER吧。

I'm using Launch4J to start my Java application and if an x64 JRE is present on the system, Launch4J seems to prefer it.

不幸的是我的应用程序无法在64位JVM上运行，因为我加载一个32位的DLL，这是不可能的，导致了的UnsatisfiedLinkError。

Unfortunately my application cannot run on a 64 bit JVM because I'm loading a 32 bit DLL, which is not possible and leads to an UnsatisfiedLinkError.

有没有办法强迫/招Launch4J只使用一个32位JVM？

Is there any way to force/trick Launch4J to use a 32 bit JVM only?

推荐答案

我有大约一年前，这个确切的问题，使用Lauch4J包装，需要一个32位的DLL（SWT-win32.dll一个小型的Java程序，如它的发生）。

I had this exact problem about a year ago, using Lauch4J to wrap a small Java program that required a 32-bit DLL (swt-win32.dll, as it happened).

我发现，如果有安装了32位和64位JVM，Launch4J将总是青睐有64位之一。这将如果64位JVM卸载，这显然不是一个可行的解决方案才有效。

I found that if there were 32-bit and 64-bit JVMs installed, Launch4J would always favour the 64-bit one. It would only work if the 64-bit JVM was uninstalled, which was obviously not a practical solution.

我发现没有办法让Launch4J至preFER的（并且要求）的32位JVM，搜索颇有几分张贴在其论坛上的问题之后。

I found no way of getting Launch4J to prefer (and require) the 32-bit JVM, after searching quite a bit and posting questions on its forum.

所以，我评估了其他的JRE转换器（我用这个列表中的好一些：<一href="http://www.excelsior-usa.com/articles/java-to-exe.html">http://www.excelsior-usa.com/articles/java-to-exe.html).

Therefore, I evaluated a good number of alternative JRE converters (I used this list: http://www.excelsior-usa.com/articles/java-to-exe.html).

我最终定居在Jar2Exe，这是唯一一个有我需要的功能。这不是免费的，但有一个评估版本，而且我认为这是不贵的。

I ended up settling on Jar2Exe, which was the only one that had the features I needed. It's not free, though there is an evaluation version, and I think it wasn't expensive.
