Java 从JBossSeam调用私有方法

我想从Servlet类调用Seam组件私有方法。我使用servlet类作为上下文HttpServletRequest，因此可以访问组件bean。检查代码示例

protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException,
        IOException {
    String userId = "U00001";
    String userGroupCd = "00000000";
    FacesContext facesContext = null;
    try {
        facesContext = getFacesContext(request, response);
    } catch (Exception e) {
        e.printStackTrace();
    }
    loginUtility = (ClientUtility) Component.getInstance("utility");
    Method clientInfoMethod = null;
    try {
        clientInfoMethod = getDeclaredMethod(loginUtility, "createClientInfo", String.class, String.class);
        clientInfoMethod.setAccessible(true);
        clientInfoMethod.invoke(loginUtility, userId, userGroupCd);

    } catch (IllegalArgumentException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
    } catch (SecurityException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
    } catch (IllegalAccessException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
    } catch (InvocationTargetException e1) {
        // TODO 自動生成された catch ブロック
        e1.printStackTrace();
        // } catch (NoSuchMethodException e1) {
        // // TODO 自動生成された catch ブロック
        // e1.printStackTrace();
    } finally {
        clientInfoMethod.setAccessible(false);
    }
}

private <T extends Object> Method getDeclaredMethod(T obj, String name, Class<?>... parameters) {
    Method declaredMethod = null;
    Method[] methods = Component.forName("loginUtility").getBeanClass().getDeclaredMethods();
    for (Method var : methods) {
        if (var.getName().contains(name) && parameters.length == var.getParameterTypes().length) {
            declaredMethod = var;
            return declaredMethod;
        }
    }
    return declaredMethod;
}

但在调用ClientInfo.invoke（）方法时，我遇到了以下错误：

有人能帮我或给我一些建议吗？

显示

createClientInfo（）

的声明。抛出异常的那一行具体在哪里？

userId

和

userGroupCd

的值是什么？我已经根据你的问题编辑了我的文章。如果你有任何想法，请告诉我。这是完整的堆栈跟踪吗？如果没有，请全部粘贴。另外，输入一个

System.out.println（userId）；System.out.println（userGroupCd）就在调用（）之前。它打印什么？我已经更新了堆栈跟踪。userId和userGroupCd只是我将传递给实用程序的登录信息。主要的问题是seam组件没有私有方法。当我使用component.getInstance（“实用工具”）.getClass（）.getDeclaredMethods（）时，其中没有私有方法。我不知道为什么。再次查看我更新的帖子。真正的错误是
loginutability.createClientInfo（loginutability.java:794）
上的
NullPointerException
。那是哪一行？另外，在您的
getDeclaredMethod（）
方法中，您通过
component.forName（“loginutability”）
获取组件，而组件名称是
“utility”
。
