测试了几个get和post方式的webservice请求，并模拟客户端测 试调用情况。在google中找到了这么一篇相关的文章：

结果做到一半出了问题，服务端总是获取不到客户端请求的数据流内容！调试了一个下午未果，却在第二天如梦方醒般的找到了原因。教训1：学习下http协 议；教训2：老外的东西不一定是对的。
周末的 测试主要还是基于jersey的webservice服务。对get和post两种方式发送请求的几种情况都做了简单的示例（上传文件的情况未测试，待续）。

客户端可以采用两种方式测试。
1，采用jersey实现的测试api：jersey-twitter-client-1.0-SNAPSHOT-jar-with-dependencies.jar
2，采用apache httpclient 模拟客户端的各种请求。
上面提到的参考e文中是采用的第二种方式。在这里我使用jersey测试api来实现。

过程中遇到的问题就是提交流的时候，错误的参考了e文中 “@Consumes ( "application/xml" ) ”的请求类型！ 结果导致service 端 接受请求的方法参数InputStream 得不到内容。换作@Context HttpServeltRequest request 参数也无济于事。于是在网上搜索，在一个国外论坛中有人提到相似的问题“上传文件得不到流里的内容，但是jetty里可以，tomcat里不可以。？”。 好像没有太大参考，但我也试了下，还是失败。。。
今天修改提交类型注解为：@Consumes("application/x-www-form-urlencoded") ，测试通过！终于才恍然大悟：application/xml是客户端接受的内容类型。哎，是应该学习下http协议的相关知识，这样的问题耽误了大半天 的时间！
另外，对于jax-ws中几个注解，简单总结下：
QueryParam--url ? 后面表示的参数 . get post 通用.
PathParam---url中的一部分，例如用{}表示的url中的一部分。get post 通用。
FormParam---post提交的form表单参数。 用于 post
（ 其他几个param稍后再学习）。

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。
