Ali-Tomcat and Pandora are containers in which EDAS depends to run services. They integrate core features such as service publishing, service subscription, and trace query. Applications must be published to Ali-Tomcat and Pandora for running.

1. Download the Ali-Tomcat package and decompress the downloaded package to a directory, such as d:\work\tomcat\.
2. Download the Pandora package and decompress the downloaded package to the deploy directory (d:\work\tomcat\deploy) where Ali-Tomcat is saved.
3. View the Pandora directory structure.
   • In a Linux system, run the tree -L 2 deploy/ command in the relevant path to view the directory structure.

     d:\work\tomcat >  tree -L 2 deploy/
                 deploy/
                     └── taobao-hsf.sar
