Tomcat6和7版本对web.xml中taglib标签的配置差异

原来部署在Tomcat6中的应用在Tomcat7中运行时报错如下错误：

java.lang.IllegalArgumentException: taglib definition not consistent with specification version

严重: Parse error in application web.xml file at jndi:/localhost/iot/WEB-INF/web.xml
org.xml.sax.SAXParseException; systemId: jndi:/localhost/iot/WEB-INF/web.xml; lineNumber: 217; columnNumber: 10; Error at (217, 10) : taglib definition not consistent with specification version

经百度发现，Tomcat7中对Web应用web.xml中的taglib标签配置稍有不同，需要在taglib标签外添加“jsp-config”标签进行包裹才行。

TomcatV6中的配置：

<taglib>
    <taglib-uri>sys</taglib-uri>
    <taglib-location>/WEB-INF/SysTag.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>tiles</taglib-uri>
    <taglib-location>/WEB-INF/tiles-jsp.tld</taglib-location>
</taglib>
<taglib>
    <taglib-uri>struts-tags</taglib-uri>
    <taglib-location>/WEB-INF/struts-tags.tld</taglib-location>
</taglib>

TomcatV7中的配置：

<jsp-config>
    <taglib>
        <taglib-uri>sys</taglib-uri>
        <taglib-location>/WEB-INF/SysTag.tld</taglib-location>
    </taglib>
    <taglib>
        <taglib-uri>tiles</taglib-uri>
        <taglib-location>/WEB-INF/tiles-jsp.tld</taglib-location>
    </taglib>
    <taglib>
        <taglib-uri>struts-tags</taglib-uri>
        <taglib-location>/WEB-INF/struts-tags.tld</taglib-location>
    </taglib>
</jsp-config>

更新配置后即可正常启动。
