步骤

1、? 新建web工程

2、? 解压birt-runtime-2_5_2.zip，将其中的WebViewerExample目录（解压birt.war也可以）下的logs、report、scriptlib、webcontent目录拷贝到新建项目的web根目录（如WebContent），将WebViewerExample/WEB-INF下的lib、platform、tlds目录及jrun.web.xml、server-config.wsdd、viewer.properties文件拷到新建项目的WEB-INF目录下。

3、? 打开WebViewerExample/WEB-INF的web.xml文件，拷贝里的配置到新建项目的web.xml里，内容如下：

4、? 如果开发需要连接数据库，则需要将数据库驱动包拷贝到新建项目的WEB-INF/platform/plugins/org.eclipse.birt.report.data.oda.jdbc_2.5.2.v20100205/drivers里；如果使用的是tomcat6.0,还需要下载commons-logging-api.jar并导入到新建项目（加到WEB-INF/lib中）。

5、? 在web根目录(如WebContent)下新建文件夹reports，之后的报表文件(*.rptdesign)就统一放到这里进行管理了。这一步不必要，在2、3、4步时已经完成嵌入birt的工作了。

6、? 这一步也不必要，有需要的话再看吧，否则请忽视。修改web配置里面的BIRT_VIEWER_LOG_DIR 、BIRT_VIEWER_IMAGE_DIR 、BIRT_VIEWER_SCRIPTLIB_DIR的配置，指定到你想要的目录，可以指定的WEB-INF目录里，默认的路径是

log -- <web根目录>/ logs、

image -- <web根目录>/report/images、

scriptlib -- <web根目录>/ scriptlib、

documents -- <web根目录>/ documents。

注：以上步骤只是在web项目里嵌入birt的运行支持，至于开发.rptdesign的插件就要读者自己找了，可以下载一个rcp（文件是birt-rcp-report-designer-2_5_2.zip）来编辑.rptdesign文件，rcp也在这个地址http://download.eclipse.org/birt/downloads/build.php?build=R-R1-2_5_2-201002221500下载。birt-rcp-report-designer-2_5_2.zip是一个eclipse，但是里面只有.rptdesign文件的开发插件，没有其他，想当的轻量级的eclipse。把开发好的.rptdesign放到上面新建项目的web根目录里就行了，或者放到其下的reports目录里，但是访问路径要记得写正确了，你懂的，不多说了。

嵌入birt 3.7.2

准备

下载birt-runtime-3_7_2.zip

地址http://download.eclipse.org/birt/downloads/build.php?build=R-R1-3_7_2-201202141408

步骤

嵌入版本3.7.2和2.5.2的方法差不多，最大的区别就是3.7.2的没有了platform目录，在tomcat6.0的运行环境也无需导入commons-logging-api.jar包。

可参考嵌入birt 2.5.2的步骤，在第2步中拷贝的文件一样，只是没有platform目录，在第4步中无需拷贝commons-logging-api.jar包，只需要将数据库驱动包加到WEB-INF/lib就行了。
