Question

SSH + jfreechart 的时候，启动tomcat,报错显示找不到CategoryData这个类..但是明明导入了包的

报错信息为：
严重: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pssVisBarAction' defined in file [F:\EPSSproject\学长代码JAVA\.metadata\.me_tcat\webapps\coSys\WEB-INF\classes\applicationContext.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/jfree/data/category/CategoryDataset
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.instantiateBean(AbstractAutowireCapableBeanFactory.java:997)
at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBeanInstance(AbstractAutowireCapableBeanFactory.java:943)
............................................（此后应该没有有，省略）

我的xml定义：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<package name="actionPss" namespace="/actionPss"
extends="jfreechart-default">

<action name="pssVisBarAction" class="pssVisBarAction">
<result type="chart">
<param name="width">600</param>
<param name="height">450</param>
</result>
</action>

</package>
</struts>

Answer 1

中文可能导致路径取值问题，将路径中的中文换成英文，再试试

Answer 2

看样子，应该是plugin的配置问题
