Question

我遇到Liferay 5.2扩展系统的麻烦，问题是在某些环境中工作而在其他环境中工作。在失败的环境中，它会抛出这些异常。

23:32:24,363 ERROR [IncludeTag:78] Current URL /web/guest;jsessionid=BFE790BBC107B870740C0268238CEA16 generates exception: Unable to compile class for JSP:

32:         if (tabs1.equals("available-AWR")) {
33:             groupCat = GroupConstants.COMM_CATEGORY_AWR;
34:             catTitle = GroupConstants.COMM_CATEGORY_AWR_LABEL;
35:         } else if(tabs1.equals("available-HOT")) {
36:             groupCat = GroupConstants.COMM_CATEGORY_HOT;

环境安装了相同的Ant，Tomcat和Java。我还授予了我的Tomcat目录的所有权限。有什么想法吗？

Answer 1

判断，因为它是编译问题而且GroupConstants.COMM_CATEGORY_AWR不是GroupConstants的标准Liferay常量。我会仔细检查以确保您导入正确的GroupConstants类并且您已正确部署了代码。

Liferay无法为JSP编译类
