Resin 報錯 javax.servlet.UnavailableException

解決辦法，在 resin 配置中加入 一下 語句就可以了

<system-property javax.xml.transform.TransformerFactory="org.apache.xalan.processor.TransformerFactoryImpl"/>
<system-property javax.xml.parsers.DocumentBuilderFactory="org.apache.xerces.jaxp.DocumentBuilderFactoryImpl"/>
<system-property javax.xml.parsers.SAXParserFactory="org.apache.xerces.jaxp.SAXParserFactoryImpl"/>
<system-property org.xml.sax.driver="org.apache.xerces.parsers.SAXParser"/>

 

例如：

<host id=www.xx.com.cn>
    <web-app id="/" document-directory="/data/www/www.xx.com.cn">

           <system-property javax.xml.transform.TransformerFactory="org.apache.xalan.processor.TransformerFactoryImpl"/>
           <system-property javax.xml.parsers.DocumentBuilderFactory="org.apache.xerces.jaxp.DocumentBuilderFactoryImpl"/>
           <system-property javax.xml.parsers.SAXParserFactory="org.apache.xerces.jaxp.SAXParserFactoryImpl"/>
           <system-property org.xml.sax.driver="org.apache.xerces.parsers.SAXParser"/>
        </web-app>
</host>
