javax.faces.component.html.HtmlInputText.getOnfocusout()Ljava/lang/String;

因为要在列表中选中一条记录，做修改删除。JSF框架中的datatable遍历出来的每个单选按钮都可以选中。所以想用myfaces的<%@ taglib uri="http://myfaces.apache.org/tomahawk" prefix="t"%>标签，于是给工程添加了myfaces1.1.jar包，web.xml 额外添加了一下配置：

 

  <!-- Extensions Filter -->
<filter>
        <filter-name>extensionsFilter</filter-name>
        <filter-class>
                org.apache.myfaces.component.html.util.ExtensionsFilter
        </filter-class>
        <init-param>
                <description>
                        Set the size limit for uploaded files. Format: 10 - 10
                        bytes 10k - 10 KB 10m - 10 MB 1g - 1 GB
                </description>
                <param-name>uploadMaxFileSize</param-name>
                <param-value>100m</param-value>
        </init-param>
        <init-param>
                <description>
                        Set the threshold size - files below this limit are
                        stored in memory, files above this limit are stored on
                        disk.
                        Format: 10 - 10 bytes 10k - 10 KB 10m - 10 MB 1g - 1 GB
                </description>
                <param-name>uploadThresholdSize</param-name>
                <param-value>100k</param-value>
        </init-param>
        <!--
        <init-param>
                <param-name>uploadRepositoryPath</param-name>
                <param-value>/temp</param-value>
                <description>Set the path where the intermediary files will be stored.
                </description>
        </init-param>
        -->
</filter>
<filter-mapping>
        <filter-name>extensionsFilter</filter-name>
        <url-pattern>*.faces</url-pattern>
</filter-mapping>
<filter-mapping>
        <filter-name>extensionsFilter</filter-name>
        <url-pattern>/faces/*</url-pattern>
</filter-mapping>

可以正常启动服务，但是打开页面时，报以下错误（JSP页面有这样的代码才报错 value="#{importTestcaseBackingBean.uploadExcelFile}"）。

解决办法：1.去掉工程中的myfaces1.1.jar,重新启动即可（不能解决遍历单选按钮的问题）。

2.在添加el-api.jar包重启服务。

3.去掉工程里头原有4的个JAR包：

javax.faces-2.1.27.jar（留该包，打开页面会报空指针错误）

jsf-api.jar

jsf-impl.jar

jsp-2.0.jar
