报表开发之birt与web项目整合

从首到尾整合birt与web项目，一边操作，一边记录。

本文章将报表与web项目整合，在web项目中访问报表，并连接数据库

1、在上一篇的birt文件的基础上，把报表整合到web项目中

2、找一个web项目，本实例为自己写的基于MySQL的一个简单小程序。

3、下图为我的web项目SMM的目录结构；

4、把birt/WEB-INF文件下lib、platform、tlds、jrun.web.xml、server-config.wsdd、viewer.properties复制到SMM的\ WEB-INF下

5、将birt/ webcontent文件夹复制到SMM根目录下

6、更改SMM/WEB-INF下web.xml文件（若不更改系统会报404错误）

  在web.xml原基础上，添加下面的代码，但要写在</web-app>之前。

<span style="font-size:14px;"><display-name>Eclipse BIRT Report Viewer</display-name><!-- Default locale setting --><context-param><param-name>BIRT_VIEWER_LOCALE</param-name><param-value>en-US</param-value></context-param><!-- Report resources directory for preview.

7、把要运行的报表复制到SMM根目录下，本实例为smm.rptdesign文件，故在index.jsp中添加

       超链接：<a href="frameset?__report=smm.rptdesign">进入报表</a>

8、在SMM\WEB-INF\platform\plugins\org.eclipse.birt.report.data.oda.jdbc_2.2.0.v20070615\drivers下，添加你要连接数据库的驱动

9、把SMM添加到D:\Tomcat 6.0\webapps下运行tomcat

10、在浏览器输入http://localhost:8080/SMM/，点击"进入报表"连接，运行成功
