flex+blazeds在线编译
第一次在CSDN上写东西，小试一下，呵呵！
我的环境是Eclipse3.4.2+Flex Builder3.0.2 + Flex SDK3.3 + Tomcat6.0.18
这次用了BlazeDS.war和WebTier.war的结合，单独的BlazeDs.war不能在线编译啊
弄了好长时间的环境，终于把目前的问题解决了
首先说一点，在学校上网示范是用Dr.COM客户端的同学，请暂时不要用3.72版本的，虽然说城市热点提供的3.72版本的客户端增加了断线自动登录，可是3.72版本的客户端与Tomcat发生冲突，在安装3.72客户端的情况下Tomcat启动不了(从外部启动可以实现，既cmd - net start tomcat6，而在Eclipse里面无法启动)。这个问题困扰了我很长时间，万万没想到竟然是和学校上网客户端冲突
FlexModule_j2ee中有个WebTier.war(从国外某Blog上找到的地址,既然上面写latest应该就是最新版本的吧)

BlazeDS.war下载

Eclipse + Flex Builder的插件应该不用多说了
用了lcds2.6里头的war文件也是不能在线编译，现在说BlazeDS是新出来的用与Flex连接Java的新东东
在新建工程的时候
Flex War File： 则选用BlazeDS.war，其实就是WebContent里面的一些配置文件而已
然后将Web Tier里头的WEB-INF文件夹下lib文件拷贝到工程下的WEB-INF对应文件夹下
WEB-INF文件夹下flex文件夹内除了service-config.xml文件外，都拷贝到工程对应的文件夹下
然后把WebContent/WEB-INF/web.xml内容替换如下

这样Run as就可以在线编译了
不过每次这样复制很麻烦啊，那么在WebContent文件夹下Shift右键w 在当前窗口打开控制台(WinNT6.0后的操作系统)然后 jar -cvf BlazeDS.war *
完成之后就做出了个BlazeDS.war文件，下次新建工程的时候直接加载这个Flex War File就可以了
俺是新手啊，尝试一下，写个小文章，呵呵，多多指教
