在 Mac 上启动我的 java 应用程序（swt）时出错

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 上运行良好，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"/>

但它仍然无法正常工作。

它抛出以下错误：

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。这些库似乎与您的 JVM 不匹配。通常，当 32 位 JVM 尝试调用 64 位库时会引发此类异常，反之亦然。
