我尝试创建自己的taglib，它扩展了现有的taglib：来自liferay-ui的input-asset-links。因此，我创建文件的Liferay-UI-ext.tld在WEB-INF/TLD我-EXT-网蒙山此xml：在添加自己的taglib之后，在视图中发生错误
<taglib
version="2.1"
xmlns="http://java.sun.com/xml/ns/j2ee"

我还添加了在web.xml这段代码：
<jsp-config>
<taglib>
<taglib-uri>http://liferay.com/tld/ui-ext</taglib-uri>
<taglib-location>path-to-file-with-tld/taglib-location>
</taglib>
</jsp-config>
最后我写了我自己的InputAssetLinksTagExt类，它扩展了my-ext-impl中的InputAssetLinksTag。
之后，我部署了一个ext插件。我打开浏览器控制面板，在那里我想添加新的文章（JournalArticle）。而我得到这个错误：

我没有改变任何东西。当我尝试访问控制面板中的网站页面时，会发生同样的情况。我有这个错误：
13:48:19,661 ERROR [http-bio-8080-exec-22][IncludeTag:129] Current URL /group/control_panel?refererPlid=10648&doAsGroupId=10182&controlPanelCategory=current_site.pages&p_p_id=156 generates exception: /html/portlet/layouts_admin/view.jsp (line: 98, column: 2) Unable to find setter method for attribute: displayStyle org.apache.jasper.JasperException: /html/portlet/layouts_admin/view.jsp (line: 98, column: 2) Unable to find setter method for attribute: displayStyle at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:42) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:443)
我使用liferay 6.2 GA3 CE和JDK 1.7。
我想念什么？
