Geoserver在Tomcat中无法启动，JAI not found

今天在将geoserver部署到tomcat时发现无法运行，费了很大的劲发现是gvSIG将JAI相关的jar包导入了jre里面，版本不一样发生了冲突。后来将geoserver下面的jai覆盖jdk和jre中的，问题就解决了。

This problem is solved just now although I cannot tell why it casued and solved. I replace the jai related jars in C:\Program Files\Java\jdk1.6.0_24\jre\lib\ext folder and C:\Program Files\Java\jre6\lib\ext folder by the jai related jars in geoserver, such as E:\Program Files\Servers\apache-tomcat-6.0.18\webapps\geoserver\WEB-INF\lib

BTW, the jai related jars are jai_codec-1.1.3.jar, jai_core-1.1.3.jar and jai_imageio-1.1.jar
