Java JSP在CQ5中不编译？

JSP does not compile in CQ5?

提问by Oliver

I am currently working on Adobe CQ 5.5, few days back I tried connecting to and External Database i.e. Oracle.

我目前正在使用 Adob​​e CQ 5.5，几天前我尝试连接到外部数据库，即 Oracle。

I succedded in that but later on I suddenly started getting weird errors.

我成功了，但后来我突然开始遇到奇怪的错误。

When ever I create new component i.e. JSP , the JSP doesn't get compiled and Classfile is not created under /var/classes/org/apache/jsp/apps

当我创建新组件即 JSP 时，JSP 不会被编译并且 Classfile 不会在 /var/classes/org/apache/jsp/apps 下创建

WHY ?????When I was trying to connect to Database I added dependent OSGi Jars in Felix console, can these jars be reponsible for the Error ??? Just guessing.. I tried removing the jars still JSP doesn't compile . sometimes it say Class cast sometimes something else ....

为什么 ？？？？？当我尝试连接到数据库时，我在 Felix 控制台中添加了依赖的 OSGi 罐子，这些罐子可以对错误负责吗？？？只是猜测.. 我尝试删除罐子仍然 JSP 不编译。有时它会说 Class cast 有时是别的东西......

Edited:: First It said taglib not found,and now it says something else this is another trace. sometimes it works,sometimes it doesn't what do I do ?? CQ is behaving weird

编辑：：首先它说没有找到 taglib，现在它说别的东西，这是另一个跟踪。有时它有效，有时它不起作用我该怎么办？？CQ表现得很奇怪

Tada it works !!

多田它有效！！

回答by anotherdave

Your error mentions that it can't resolve the Sling tag library. Are you including a reference to it in your JSP (either directly or via the global.jsp script that references it?). I.e. within your JSP:

您的错误提到它无法解析 Sling 标签库。您是否在 JSP 中包含对它的引用（直接或通过引用它的 global.jsp 脚本？）。即在您的 JSP 中：

<%@taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0" %>

<%@taglib prefix="sling" uri="http://sling.apache.org/taglibs/sling/1.0" %>

or

或者

<%@include file="/libs/foundation/global.jsp" %>

<%@include file="/libs/foundation/global.jsp" %>
