see the "allowLinking" property.
As far as how to create the symlink when the app is deployed, not sure beyond running some sort of script when the application loads (using a context listener perhaps).

Hi All,
Does anyone know of a way to set an alias to an external directory that contains images to be displayed on a web page?
Maybe explaining what I need to do would help:
I have a directory, for example: /tmp/images I have a webapp in: /opt/tomcat/webapps/myapp
I need to be able to store uploaded images in /tmp/images (which I have working fine) and I need to be able to display those images via the jsp's in myapp. Is it possible to have an alias called myapp/images that points to /tmp/images or can I maybe use a symlink(can tomcat follow the symlink?) or is there some other way I can do this, other than using a servlet to retrieve/return the images?
I need to be able to do this so that when the webapp is updated/redeployed, the images will not get deleted.
I am running tomcat 5.0.28 on SUN's Java 1.4.2_08 on a variety or Linux/UNIX systems.
Thanks in advance,
Matt
