taglib definition not consistent with specification version_综合

问题描述：

从TongWeb6、tomcat7及之前老版本上移植到TongWeb7上的应用报错如下：

原因：

JavaEE规范更新对web.xml中的taglib格式做了变更，不兼容老格式。

解决办法：

修改web.xml，如下：

修改前：

<taglib><taglib-uri>/custom</taglib-uri><taglib-location>/WEB-INF/tld/custom.tld</taglib-location>
</taglib>
<taglib><taglib-uri>/test</taglib-uri><taglib-location>/WEB-INF/tld/test.tld</taglib-location>
</taglib>

修改后增加<jsp-config>：

<jsp-config><taglib><taglib-uri>/custom</taglib-uri><taglib-location>/WEB-INF/tld/custom.tld</taglib-location></taglib><taglib><taglib-uri>/test</taglib-uri><taglib-location>/WEB-INF/tld/test.tld</taglib-location></taglib>
</jsp-config>
