这一段时间快被这个晕死人的软件工程大作业折腾死了,总体感觉倒也不是说有多难,但理解这个juddi做的接口要uddi基础知识,像我这样菜鸟级用户,连web service都没怎么听说过,摸到门都花了好多时间和精力。网上这方面的资料实在是太少了,中文的帖子全是讲juddi的安装配置的,而且都是转来转去的,有的安装时遇到的关键[size=medium][/size]性的问题都没有人回答,英文都说实话又看不太进去...= =诶诶诶~
由于参考资料少,又没有花太多心思去读,我们一开始绕到 IBM的uddi4j上去了,花了半天调试通了能够findBusiness了,总算对uddi有了一个初步的概念。但是这段路也算是个小小的弯路吧~后来才意识到uddi4j的那个测试的代码和juddi的jsp界面提供的应该都是注册和查询服务等的API,晕~真够笨的。
现在差不多把这个作业弄了大半部分了,自己先做个初步的总结,留在这里备忘。
0.老师给的课程作业要求
基于JUDDI的WEB服务注册中心,增加WEB服务非功能属性描述模块。利用第1组从WORDNET获取的语义信息在JUDDI注册中心查询用户需要的服务, 查询利用JUDDI的查询API自动完成。(并可根据查询结果对服务进行进一步分类,包括严格按功能、输入/输出的个数、类型完全一致和部分一致的分类.)
JUDDI是Apache基金会下Web Services小组的一个开源项目,也是基于java并且符合UDDI规范的实现。主要具有以下特点:
开放源代码,底层包可以采用jdk1.3及其以后版本(后来证明juddi是不完全支持JDK1.6的,这一点上花了太多的时间,好在丁丁同学目光如炬),具有平台无关性;
后台数据库可以采用任何支持ANSI标准的数据库,例如MySQL,DB2等;
可以将其发布到任何支持Servlet2.3标准的java应用服务器上,例如JakartaTomcat, WebSphere,WebLogic等;
1.安装
网上说安装的帖子很多,基本流程还是对的,我这里主要参考了http://www.cnblogs.com/kevin- wu/archive/2007/05/21/754157.html 这篇帖子
但是一定要注意JDK版本不能是1.6 ,因为如果是JDK1.6,在测试安装是否成功的页面http://localhost:8080/juddi/happyjuddi.jsp 时,就会有SOAPMessage和SAXParserFactory两个类Found in an unknown location,其中SOAPMessage还是很重要的,应该是和SOAP通信有关,如果找不到就会导致后面findBusiness等不能执行,出现fault string and possibly fault code is not set的错误,网上提问的很多但都没有找到答案,这里要鸣谢丁丁同学,不然后面都做不下去了。
如果运行环境是JRE1.5的版本那么这个包就能找到
Looking for: javax.xml.soap.SOAPMessage
+Found in: D:/Program Files/Tomcat/webapps/juddi/WEB-INF/lib/saaj.jar
2.使用
观察到 Tomcat/webapps/juddi/console目录下的jsp文件,每个api都用一个jsp文件实现,最终都提交表单到 controller.jsp文件。对这个controller.jsp,它内部实现了SOAP的一些通信机制,这里我们没有深究,只是简单地把它拿来用。
我们在数据库中设计了一个service的非功能属性的table用来拓展juddi功能
USE juddi;
CREATE TABLE service_quality (
SERVICE_KEY varchar(41),
PRICE varchar(10),
USER_VALUATION varchar(5),
EXECUTE_TIME varchar(10),
RELIABILITY varchar(5),
APPLICABILITY varchar(5),
LANGUAGE varchar(10),
SECURITY varchar(5),
PRIMARY KEY (SERVICE_KEY)
);
下一步要解决的是
改动这个目录下的API,查找服务时既能查出原有的服务的属性,又能查出我们新加入的非功能属性。
简单分析了一下(这里可能会有不确切的地方),要注册一个服务,首先要得到一个authToken,然后根据它注册bussinessEntity信息,然后注册tModel信息,最后注册service信息。
2.1 get_authToken
打开 http://localhost:8080/juddi/console/get_authToken.jsp,可以看到默认提交的表单是一个SOAP 请求,代码表示它将soap_request传递给controller.jsp,然后将返回的消息responseMessage显示在下面的文本区中。***表示可能需要填写的部分,在这里*号部分是我们要提交的内容userID和cred,如果用户名userID不正确则会返回一个SOAP应答,但是cred随便填一个数也能得到authToken,不知道是为什么了。填写juddi和juddi,然后submit,得到一个authToken,即authToken:8FE01220-DD7D-11DD-ADFB-B7B7EF162770。
