websphere 7(和Spring Roo)与javax.el.ELException不兼容
|
我有一个前端基于Spring Roo 1.1.2 jspx文件的应用程序。
每个想法在Tomcat 6中都可以正常工作,但是如果我在Websphere 7中部署相同的应用程序(类加载器:最后一个父级),则会出现异常:
java.lang.ClassCastException:java.lang.NullPointerException与javax.el.ELException不兼容

该应用程序具有Flex / BlazeDS部分,可以正常工作。但是也有这个JSP(x)部分。 Spring控制器可以工作,但是JSPX出问题了,我不知道从哪里开始,当我理解规范权利时,比WAS7提供的JSP 2.1还要多,这正是我所需要的。
WAR的POM的相关部分是:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>com.springsource.javax.servlet.jsp.jstl</artifactId>
<version>1.2.0</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>
有人可以给我提示吗?

异常的原因是WEB-INF / layout / default.jspx中的line4ѭ行),我绝对不知道为什么,因为所有其他tagx都可以工作(我整晚都在这里度过)。最简单的工作方法是\手动直接在default.jspx中“包含\” / WEB-INF / tags / util / load-scripts.tagx的相关内容(然后可以删除load-scripts.tagx) 将会发生一个新的验证错误:这是因为IBM似乎在解析
中的jstl函数时遇到了问题。例如:
。这恰好是在步骤1中从
复制到
的行之一。我的工作方式是:替换为:
通过:
现在您将看到一些内容,但是我将看到输出,您将看到,IBM Websphere 7不会从divs除去名称空间定义。但是在模板中,您将会有很多
元素,因此您需要做的就是将它们全部提取到
元素中(在所有jspx文件中)。这样文件看起来像这样:
我不确定是否需要执行此步骤,但您不确定是否需要100%的下一步。 现在,除了Java脚本之外,其他所有东西都可以使用。那是因为IBM Websphere 7,规范化JSPX输出。这样的行:
不幸成为
IE和Firefox(3)忽略了此脚本标签。解决方法是在步骤1中复制的所有(3)相关脚本标记的脚本部分中添加ѭ16。
至少您的default.jspx看起来像这样:

此外,Websphere 7还没有内置的对png文件的支持,除非将它们转换为jpg并编辑标签以使用jpg而不是png文件,否则它们将不会呈现,或者您可以为Websphere 7安装png支持的插件 编辑: 在web.xml中添加以下内容也可以解决问题
