我在尝试在tomcat上运行Oracle ADF时会得到以下异常

当我打印BindingContext.keySet()的键时，我会看到找不到的<ObjectName>，但它具有以下名称结构<ObjectName>@<Path_to_databindings>_DataBindings_cpx。任何帮助将不胜感激。

我在使用以下代码编程中找到了此错误的小解决方法;

BindingContext bc = // Load BindingContext
for (Object k:bc.keySet()) {
    if(k.toString().endsWith("@<Path_to_databindings>_DataBindings_cpx")) {
        String newKey = k.toString().substring(0, k.toString().indexOf('@'));
        bc.put(newKey, bc.get(k));
    }
}
