大家好！
在我的 EOS 项目中，有一个页面流，共三个元素：“开始”---“视图”----“结束”。其中视图与一个jsp文件(A.jsp)关联。
页面流完成的任务是在 jsp 文件呈现的网页上展示一个 flash （一个饼图），控制饼图的数据是在jsp 文件中生成的，然后把数据传递给一个javascript函数，由此函数具体完成flash的展现。
此饼图来自 http://www.fusioncharts.com/Default.asp， 为了展现饼图需要下载flash 文件，fusioncharts提供许多种flash。在下面的代码中使用的是 Doughnut2D.swf 。因为此论坛的上传附件功能无法使用，所以请想要帮助我的朋友到 www.fusioncharts.com/Default.asp 下载
FusionCharts v3 (链接就在 FusionCharts v3 Links 下方的 'download')。解压缩后，可以看到 Doughnut2D.swf 在 charts 目录下。使用此flash很简单，直接把它放在 项目的webroot (Eclipse) webcontent (EOS Studio, Web Project) 下即可， 我是把它放在webroot / webcontent 的charts目录下。 javascript 文件 FusionCharts.js 在JSClass目录下。
我在 Eclipse 中以及在 EOS Studio 建立 Web Project 都是可以通过的。
但在 EOS Studio 建立的EOS项目中建立上述三元素页面流中无法通过。
如果在 A.jsp 文件中 使用 <<script>> ...... <</script>> 调用javascript函数，似乎调用不到 javascript函数。如果使用<<h:script>>调用javascript函数，感觉能够调到 javascript函数。但会出现下列错误
h:script must be empty according to TLD.
请大家帮助。
jsp文件内容如下

-----------
javascript 程序 FusionCharts.js 如下所示.
（主要作用是展示一个flash swf文件，具体要展示的swf文件名，包含在上面的jsp 文件中的变量strXML里，并通过 myChart1.render("chartDiv"); 语句传进 javascript 函数）FusionCharts.js 可以在下载的fusioncharts的JSClass目录下找到。
