我在 OpenXava 4.6 中创建了一个 portlet。但是一旦部署在 Liferay 6.1.1 CE GA 下，它就不能正常运行。

这些是问题：

a.) OX 4.5.1 和 4.6 创建的 web.xml 无法被 Liferay 6.1 识别

15:23:28,665 INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][AutoDeployDir:182] Processing <..>.war. This is attempt 2.
15:23:28,673 INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][PortletAutoDeployListener:77] Copying portlets for ../liferay-portal-6.1.1-ce-ga2/deploy/<..>.war
15:23:28,676 INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][BaseDeployer:1674] ../liferay-portal-6.1.1-ce-ga2/deploy/<..>.war does not have a WEB-INF/liferay-plugin-package.xml or WEB-INF/liferay-plugin-package.properties
15:23:28,677 INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][BaseDeployer:763] Deploying <..>.war
15:23:33,110 ERROR [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][AutoDeployDir:210] com.liferay.portal.kernel.deploy.auto.AutoDeployException: com.liferay.portal.kernel.deploy.auto.AutoDeployException: web.xml must be updated to the Servlet 2.4 specification

b.) web.xml 文件需要有这个头：

<?xml version="1.0" encoding="UTF-8"?>

<web-app id=".." version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
<http://java.sun.com/xml/ns/j2ee%5C>" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance\
<http://www.w3.org/2001/XMLSchema-instance%5C>"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd\
<http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd%5C>">

<display-name>...</display-name>
...

c.) 即使在按照上述修改“web.xml”文件（并创建一个新的 WAR 文件）之后，Liferay 也能够加载 portlet，并且它出现在可用 portlet 列表中。但是 portlet 不起作用：

15:35:01,457 INFO [com.liferay.portal.kernel.deploy.auto.AutoDeployScanner][PortletAutoDeployListener:87] Portlets for ../liferay-portal-6.1.1-ce-ga2/deploy/<..>.war copied successfully. Deployment will start in a few seconds.

15:35:04,653 INFO  [pool-2-thread-2][PluginPackageUtil:1033] Reading plugin package for <..>
15:35:04,653 WARN  [pool-2-thread-2][PluginPackageUtil:1131] Plugin package on context <..> cannot be tracked because this WAR does not contain a liferay-plugin-package.xml file

d.) 我手动将文件“liferay-plugin-package.xml”添加到 WAR 文件中，但 Liferay 仍然没有正确显示 portlet。

欢迎任何建议。谢谢。

听起来您不是在使用 Liferay IDE 来创建 portlet，我建议您这样做，因为它确实有助于开发！( Liferay IDE 安装指南& Liferay IDE 入门指南)

请注意，您需要包含 liferay-plugin-package。属性、liferay-portlet.xml、portlet.xml、liferay-display.xml 和 web.xml 在您的 portlets docroot/WEB-INF 文件夹中。

每个文件的内容应类似于以下内容：

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" 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">
     <display-name>my-portlet</display-name>
    <jsp-config>
        <taglib>
            <taglib-uri>http://java.sun.com/portlet_2_0</taglib-uri>
            <taglib-location>
                    /WEB-INF/tld/liferay-portlet.tld
            </taglib-location>
         </taglib>
         <taglib>
            <taglib-uri>http://liferay.com/tld/aui</taglib-uri>
            <taglib-location>/WEB-INF/tld/aui.tld</taglib-location>
            </taglib>
    </jsp-config>   
</web-app>

liferay-display.xml

<?xml version="1.0"?>
<!DOCTYPE display PUBLIC "-//Liferay//DTD Display 6.1.0//EN" "http://www.liferay.com/dtd/liferay-display_6_1_0.dtd">

    <category name="category.sample">

OpenXava 还不支持 Liferay 6.1，我们将为未来的 OX 版本添加 Liferay 6.1 支持。

然而，一些 OX 用户已经实现在 Liferay 6.1 上部署 OX 应用程序，只需更新 web.xml，看看 OpenXava 论坛中的下一个主题：

https://sourceforge.net/p/openxava/discussion/419690/thread/79695196/

https://sourceforge.net/p/openxava/discussion/419690/thread/da118e74/

因此，我认为您的问题 d) 与其他问题有关。您是否已将 jta.jar 和 ejb.jar 复制到 Liferay 的 lib 文件夹中？你能把堆栈跟踪产生的 portlet 放在这里吗？
