仅当我尝试在 griffon 中将其作为 webstart 或 applet 运行时，我的应用程序中才会出现以下错误：
net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize application.

我需要在我的代码中添加什么来克服这个问题（我正处于开发阶段，还不想部署）？
我使用了命令：“griffon run-webstart -clean”
这是我的控制器文件：
package test1
import griffon.util.GriffonNameUtils as GNU
import griffon.transform.Threading
class Test1Controller {
def model
def clear = {
model.griffonClass.propertyNames.each { name -> model[name] = ''
}
}
@Threading(Threading.Policy.SKIP)
def submit = {
java.swing.JoptionPane.showMessageDialog(
app.windowManager.windows.find{it.focused},
model.griffonClass.propertyNames.collect([]) {
name -> "${GNU.getNaturalName(name)} = ${model[name]}"
}.join('n')
)
}
}
