tomcat发布基于jersey的WebService（三）

可恶的异常！

周末的一个下午都被这个异常给耽误了。哎

严重: StandardWrapper.Throwable

很奇怪的原因，之前的jersey测试都是基于myeclipse自带的tomcat进行部署调试的，未发现任何异常。这次我把jersey应用到以前做的project中，然后部署在我安装的tomcat6.0中，结果部署除了这么个异常！google也找不到任何解答。将jersey测试项目也部署到tomcat6.0中也出现这样的异常。但是部署在myeclipse自带的tomcat中就不出现这样的异常，深度不解~

就这样折腾了一个下午的时间~

第二天晚上又打开来调试，问题依旧，没办法登陆jersey官网看看，在guide中发现这样一句：

Non-maven developers require:

jersey-server.jar
,

jersey-core.jar
,

jsr311-api.jar
,

asm.jar

于是将jersey包精简到以上几个，去掉了几个client测试相关的jar和spring支持jar，还有一个jersey-multipart-1.1.2-ea.jar（问题就是个jar）。启动tomcat6，异常消失了。^_^

反复改变部署的jars，直接的方法就是把jersey-multipart-1.1.2-ea.jar去掉。其他的jar目前倒是没有产生影响。

哎，水平有限，我也总结不出个合理的解释，只能告诉大家以后jersey不要部署多余的jar！（好像之前也是参考某个blog建议把contribs和lib下的jar都复制过去）。有知道原因的没？各位。
