Question

我正在Windows 7（32位）机器上开发一个java应用程序。我在我的应用程序中使用了SWT并通过Java Web Start运行它。它在Windows 7上工作正常，但是当我尝试在MAC OSX 10.6.8上运行它时，它无法启动我的应用程序。我在我的库中添加了“swt-3.7M5-win32-win32-x86.jar”。我在我的jnlp文件中添加了以下行，以便在32位JVM上运行它：

<j2se version="1.6+" java-vm-args="-d32" href="http://java.sun.com/products/autodl/j2se"/>

但仍无效。

抛出以下错误：

这是根本问题：

Caused by: java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
no swt-win32-3721 in java.library.path
no swt-win32 in java.library.path
Can't load library: /Users/Rajivj/.swt/lib/macosx/x86/libswt-win32-3721.jnilib
Can't load library: /Users/Rajivj/.swt/lib/macosx/x86/libswt-win32.jnilib

首先检查这些lib文件是否存在。我相信他们是因为它说“UnsatisfiedLinkError”并且没有抱怨找不到文件。在这种情况下，请检查您的SWT安装。看来这些库与您的JVM不匹配。通常，当例如32位JVM尝试调用64位库时会抛出此类异常，反之亦然。
