我正在将Spring框架从3.0版更新到4.3版。使用IBM Websphere和使用ANT而不是Maven进行Portlet开发。我检查了类路径，它包含MessageTag的类文件。在以前的版本（3.0）中，MessageTag位于Web.Servlet包中，现在在此版本（4.3）中，此类位于包webmvc中。包名称相同。
但每次尝试运行门户网站时，我都会收到以下错误消息。

我看到了一些关于此的帖子，他们说我需要通过添加'el-ignored'标签来更新web.xml。但这也行不通。
<jsp-config>
<jsp-property-group>
<url-pattern>*.jsp</url-pattern>
<el-ignored>true</el-ignored>
</jsp-property-group>
</jsp-config>
有人可以帮我解决这个问题。此外，如果还有其他信息，请告诉我。谢谢！ ：）
