liferay 6.1.1 中的 xml 解析错误

Question

我尝试在 liferay 6.1.1 上部署我的应用程序并收到此错误(当我在 6.0.6 上测试此应用程序时一切正常)。这意味着什么？

Caused by: com.liferay.portal.kernel.xml.DocumentException: Error on line 1 of document : The value following "version" in the XML declaration must be a quoted string. Nested exception: The value following "version" in the XML declaration must be a quoted string.

up: 不知道是哪个文件报错了。 完整日志

Answer 1

问题可能与您的 web.xml 文件有关。我有一个类似的问题，一个 portlet 在 6.1GA1 下运行良好，但在 6.1GA2 下运行良好。当 Liferay 部署 portlet(和 Hook 等)时，它会重写文件和其他文件以添加过滤器、库等。因此错误可能不是您最初创建的文件，而是 Liferay 生成的文件。

在我的例子中，Liferay 将 web.xml 的第一部分从

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

类似于

<?xml version=<filters>[other stuff]</filters>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

所以是修改的第一行导致了这个问题。我使用 <!-- --> 注释掉了一些 XML并删除这些部分解决了问题。但恕我直言，这是一个错误。
