weblogic,struts,cewolf图象显示出错，在线等待...

我在项目（weblogic+struts）中需要显示走势图，调用cewolf，总是提示错误：C:\bea\wlserver6.1\config\mydomain\applications\DefaultWebApp\WEB-INF\_tmp_war_myserver_myserver_DefaultWebApp\jsp_servlet\_public\_flagfund\__fundtrend.java:267: cannot resolve symbol
probably occurred due to an error in /public/FlagFund/fundTrend.jsp line 205:
</cewolf:data>

</cewolf:chart>
weblogic显示：
java.io.IOException: Compiler failed executable.exec。...
weblogic.utils.compiler.CompilerInvoker.compileMaybeExit...

cewolf的包都已经加了，web.xml也写了配置。
