我正在寻找一种将两个 Axis 数据类型（由 WSDL2Java 生成）相互转换的可能性。两种数据类型都包含完全相同的属性，因为它们都来自相同的 XSD。

问题是 Axis 将它们生成为分离的数据类型。

数据类型1：

public static class AbstractAsynchronousResponse extends AbstractResponse implements org.apache.axis2.databinding.ADBBean {

        /*
         * This type was generated from the piece of schema that had name =
         * AbstractAsynchronousResponse Namespace URI =
         * http://www.example.org/AllCallbackTypes Namespace Prefix = ns2
         */
.........}

数据类型2：

public static class AbstractAsynchronousResponse extends AbstractResponse implements org.apache.axis2.databinding.ADBBean {

        /*
         * This type was generated from the piece of schema that had name =
         * AbstractAsynchronousResponse Namespace URI =
         * http://www.example.org/AllCallbackTypes Namespace Prefix = ns2
         */
.........}

现在我想做这样的事情：

AbstractAsynchronousResponse1 response1 = new AbstractAsynchronousResponse1();
AbstractAsynchronousResponse2 response2 = (AbstractAsynchronousResponse2) response1;

有解决办法吗？

这是我为解决此问题而创建的方法。然而，这并不是很好，但它确实有效。

/**
     * This will cast an {@link ADBBean} implementation to another
     * {@link ADBBean}, but the Implementation will be a subClass of
     * <b>parentLocationOfSourceClass</b>.<br>
     * This only is possible because of the structure of all ADBBean
     * implementations created by <code>Axis2 ADB-Databinding</code>. If you
     * cange the Databinding you probably have to adapt this Method.
     * 
     * @param inputADBBean

     * @param parentLocationOfSourceClass
     *            This is meant to be the <code>ClientStub</code> Class created
     *            by <code>Axis2 ADB-Databinding</code>. The Implementation of
     *            the <code>inputADBBean</code> has to be available with the
     *            same name in the <code>ClientStub</code>
     * @return An {@link ADBBean} implementation defined as SubClass of the

    public static ADBBean castADBBean(ADBBean inputADBBean, String parentLocationOfSourceClass) throws Exception {
