如何为JSF应用程序实现GZipFilter

如何解决如何为JSF应用程序实现GZipFilter

您好，所有iam目前都在致力于JSF 2.1应用程序的性能改进。我尝试了以下链接Which compression (is GZIP the most popular) servlet filter would you suggest?，我试图在IBM Websphere上实现，但是应用程序无法启动并在下面显示错误。我会错过任何罐子吗

<filter>
    <filter-name>CompressionFilter</filter-name>
    <filter-class>com.utilities.CompressionFilter</filter-class>
    </filter>

    <!-- FILTER MAPPINGS -->
    <filter-mapping>
    <filter-name>CompressionFilter</filter-name>
    <url-pattern>*.js</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>CompressionFilter</filter-name>
    <url-pattern>*.css</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>CompressionFilter</filter-name>
    <url-pattern>*.html</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>CompressionFilter</filter-name>
    <url-pattern>*.jsp</url-pattern>
</filter-mapping>
