jasperreports flash预览报表功能

jasperreports FLash预览报表功能

???? 几天前，在做预览报表功能的时候，预览总是不成功，但是后台有没有抛出异常，

因为自己的配置以及都成功了，觉着没问题，jar包也导入了，该有的都有了。

后来无意间发现，原来是我的版本不对，我jar包的版本是5.0.1的，但是flash的版本：jasperreports-flash-4.0.0.swf

导致最后总是预览不出来，后来我把flash版本换成匹配的版本即：jasperreports-flash-4.5.0.swf??之后就成功了。

注意：在预览报表的之前，需要先将数据填充到报表中，然后才能进行预览，不然会抛异常

主要的配置是:1、web.xml 需要加入如下信息：

  <servlet>
  	<servlet-name>Xml4SwfServlet</servlet-name>
  	<servlet-class>net.sf.jasperreports.j2ee.servlets.Xml4SwfServlet</servlet-class>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>Xml4SwfServlet</servlet-name>
  	<url-pattern>/servlets/xml4swf</url-pattern>
  </servlet-mapping>
?<servlet>
? ?? ?<servlet-name>ImageServlet</servlet-name>
? ?? ?<servlet-class>net.sf.jasperreports.j2ee.servlets.ImageServlet</servlet-class>
? </servlet>
? 
? <servlet-mapping>
? ?? ?<servlet-name>ImageServlet</servlet-name>
? ?? ?<url-pattern>/servlets/image</url-pattern>
? </servlet-mapping>?
