Question

我使用IBM Rational Application Developer 9.0创建了一个简单的portlet（JSR-286）。我想写一个junit测试用例。我已按照链接中提供的步骤进行操作：http://www.ibm.com/developerworks/opensource/library/wa-portletunit/index.html 但我无法成功，获得空指针异常。以下是代码段：

public void testdoViewOfGenericBookmarkWithPortletUnit() throws Exception
{
    PortletRunner runner = getPortletRunner();
    PortletUser user = new GenericPortletUser();
    runner.setUser(user);
    WebResponse bookmarkResponse=runner.getResponse();

    WebLink[] links=bookmarkResponse.getLinks();
    assertEquals(links.length,1);
    assertEquals(links[0].getText(),"IBM");

}

private PortletRunner getPortletRunner() throws Exception {
    File webInfDir=new File("/home/akshay/rad_workspace/MyPortal/WebContent");
    Class portletClass = MyPortalPortlet.class;
    PortletRunner runner = PortletRunner.createPortletRunner(portletClass,webInfDir,    
"MyPortal");
return runner;
}

问题在于我们在getPortletRunner方法中获取PortletRunner实例，错误堆栈跟踪如下所示

拜托，有谁可以帮助我。我怀疑portletunit不支持JSR-286。还有哪些其他库可用于使用IBM Rational Application Developer 9.0构建portlet（JSR-286）的junit测试

如何为使用JSR-286创建的IBM Portlet编写junit测试用例？
