我已经在我的eclipse版本:3.3.2中集成了JFormDesigner，我所面临的错误并不完全在主题中，因为它受150个字符的限制。
所以我在下面列出了:

上面是我在运行JPanel类时遇到的错误日志，该类从JFormDesigner转换为Java程序。
我的程序运行没有错误，但它没有显示我的UI框架。我一直在寻找这个问题，也得到了一些新的结果。
删除下列文件
.metadata.pluginsorg.eclipse.ui.workbenchworkbench.xml
.metadata.pluginsorg.eclipse.core.resources.snap
但这并没有解决我的问题。我想知道的是，当我们在Eclipse中安装JFormDesigner插件时，我们需要注意的事情。
有人能解决吗?请让我知道。

这是从JFormDesigner转换过来的代码。当我运行这个，没有输出零错误。它至少应该向我展示设计好的GUI。
代码试图找到一个构造函数
public BrowserInformationControl(Shell parent, int shellStyle, int style, String statusFieldText)
表示内部类org.eclipse.jface.internal.text.html.BrowserInformationControl。这在包括3.3在内的旧版本的Eclipse中曾经存在，但在以后的版本中不存在。
您需要使用具有此版本BrowserInformationControl的旧版本Eclipse运行，或者更新到更最新的代码。
由于BrowserInformationControl是一个内部类，这段代码违反了Eclipse API的参与规则，因此在不同版本的Eclipse上运行是不安全的。
