其中
   DWREngine.XMLHttpRequest 是ajax方式；
   DWREngine.IFrame是在activex被禁用时使用的方式；
  DWREngine.ScriptTag 是在跨域调用时使用的方式。
我在使用DWREngine.ScriptTag 方式时遇到一个问题，出现错误“please specify scriptTagBase property”.
如果有朋友知道解决的办法，请告诉我，不胜感激！

]]>如何开始一个基于oracle数据库的appfuse项目http://www.blogjava.net/maja/archive/2005/08/26/11173.html蚂蚱蚂蚱Fri, 26 Aug 2005 02:20:00 GMThttp://www.blogjava.net/maja/archive/2005/08/26/11173.htmlhttp://www.blogjava.net/maja/comments/11173.htmlhttp://www.blogjava.net/maja/archive/2005/08/26/11173.html#Feedback0http://www.blogjava.net/maja/comments/commentRss/11173.htmlhttp://www.blogjava.net/maja/services/trackbacks/11173.html 二、下载ant1.6.5并解压
三、下载并安装tomcat5.0+
    如果数据库放在本机请更改tomcat的监听端口（因为oracle的tnslistner的监听端口为8080，
    会引起端口冲突！）
四、设置环境变量
   1、jdk：JAVA_HOME=

   2、tomcat ：CATALINA_HOME=

   3、ant ：ANT_HOME

五、 oracle
   1、创建用户
CREATE USER appftest IDENTIFIED BY appftest;  
GRANT CONNECT TO appftest;
GRANT RESOURCE TO appftest;

   2、oracle jdbc driver
copy ojdbc14.jar to {AppFuse home}/lib directory

   3、在{appfuse path}/build.properties中加入下面属性
database.jar=${lib.dir}/oracle/ojdbc14.jar
database.type=oracle
database.host=localhost
#use the database schema owner and password created in step #1 above here
database.username=appfuse
database.password=appfuse

hibernate.dialect=net.sf.hibernate.dialect.Oracle9Dialect
database.driver_class=oracle.jdbc.driver.OracleDriver
database.url=jdbc:oracle:thin:@localhost:1521:oracledb


六、修改 web/WEB-INF/classes/mail.properties

七、生成应用
   cd {appfuse path}
   ant new -Dapp.name=myappname -Ddb.name=appftest

   cd ..\myappname
   ant setup
八、检验
   启动tomcat
   在浏览器敲入url：http://localhost:port/myappname检验是否成功！

  好了，一切都完成了，祝你好运！

4、编译（编译java源文件、copy属性文件和xml等文件、编码转换）
5、建立WAR包
6、发布
