未找到Liferay jsp页面

Question

我遇到了重定向到jsp页面的问题。

    <portlet:renderURL var="DLMSnewSearch">
    <portlet:param name="mvcPath" value="/view.jsp" />
</portlet:renderURL>
<p>
    <a href="<%=DLMSnewSearch%>">&larr; New Search</a>
</p>

Eclipse抛出警告：未找到“/view.jsp”。

抛出异常：

一直有效，直到我重新安装了我的Linux Mint并从现有源添加了Liferay项目......这是我从之前的Mint保存的备份。 提前谢谢。

由于您使用Eclipse IDE为Liferay开发，我相信以下内容将适用。您可以通过跟踪此错误跟踪器来获取该软件的修补程序，或者等待将其合并到滚动版本中。

Eclipse Java IDE

听起来你受到Liferay软件中已知错误的影响。通过在IDE中执行以下步骤来解决此问题：

1. 打开“项目属性”对话框。
2. 选择＆＃34;验证＆＃34;页。
3. 选中复选框，＆＃34;启用项目特定设置。＆＃34;
4. 找到＆＃34; JSP参考验证，＆＃34;设置并将其关闭以进行手动和构建。
