java.lang.NoClassDefFoundError:无法初始化类javax.swing.UIManager

Question

我遇到了这个错误,有谁知道为什么会这样？Java版本:1.6.0_16

java.lang.NoClassDefFoundError: Could not initialize class javax.swing.UIManager
    at javax.swing.LookAndFeel.installColorsAndFont(LookAndFeel.java:191)
    at ilog.views.chart.IlvChart.updateUI(Unknown Source)

并打印另一个错误:

java.lang.UnsatisfiedLinkError: shell32.dll: Cannot load shell32.dll from system directories.
    at sun.awt.windows.WDesktopProperties.init(Native Method)
    at sun.awt.windows.WDesktopProperties.<init>(WDesktopProperties.java:66)

他们有任何关系吗？

假设您在Windows上运行,shell32.dll应该在您的system32文件夹中,例如c:\Windows\System32\shell32.dll.

没有它你似乎不可能运行Windows ...也许你的JDK/JRE已经腐败了？也许注册表项误入歧途？可能值得重新安装JDK/JRE - 如果您使用的是64位计算机,请确保安装64位版本.虽然我希望32位版本也可以工作(就像在64位Windows上的任何其他32位应用程序一样),但可以想象它会导致这种问题.
