请问apache camel如何实现webservice的转发？

可以的，按照你上面说的A就是个反向代理服务器的话。

Camel就没必要用Webservice了，就用servlet到http就可以了

from(servlet:///as).to(http://xxx.xxx.xxx.xxx/as?bridgeEndpoint=true)

Web.xml配置：

jar包依赖见http://my.oschina.net/u/574870/blog/164215

版本我用的2.6.0用新版本的话，jar包依赖会少一些。

要工程的话，你把邮箱发给我

@滄海一夢 我也有同样的问题，麻烦给我也发一下工程吧，我的邮箱是10024940@qq.com，非常感谢！

根据上面的配置信息，我自己搭建了一下环境，已经解决了，不过我用2.6这版在jboss5.1下运行不起来，后来改用2.8就没事了。

我也遇到同样的问题。谢谢 88103596@qq.com
