Pinned topic How do I define a virtual directory in WASCE?

‏2012-05-01T19:27:41Z |
I am face lifting an already built web application .war from WAS 6.1 to WASCE 3.0.0.1. The previous deployment relied on a virtual or symbolically linked directory in the web_app_home pointing to a directory outside the web application. So inside the app.war directory was a symlink called tagdocs that pointed to another directory on the server. This worked well and for reasons out of my control we would like to keep the data model the same. However, on WASCE out of the box this doesn't seem work. I have searched and found that you should be able to update the Tomcat deployment to look for external directories. However, WASCE isn't like a normal tomcat install and I am unclear what would need to be updated.

As an aside, this works on Tomcat 7.0.27 with symlink (locally in dev env using plain tomcat). However I have tried several instances of WASCE and none will recognize a symlinked directory. I don't know if this is a bug in the embedded Tomcat of WASCE or simply because they work differently. Any help appreciated!

    In Geronimo side, a latest change[1] added the expanded war deployment support for Geronimo 3.0-beta, I guess it can solve your problem, Hope it helps.

    You can ask for a latest geronimo-beta snapshot link to try in geronimo mailing list. This change might be integrated into next CE release.

    Thanks for the feedback. I may try that route.

    However, I did try to define the directories within the webapp itself and dynamically reference created directories. Specifically, in the Web Content folder I create a folder called tags. As the user interacts w/ the site, a new directory and file under the dir tags will get created. For simplicity it would create web_app_home/tags/dir1/tag1.tagFile. I then dynmaiclly create an anchor tag link (nothing fancy, just build the url) to link to the newly created tag file so it can be read. ie, link will be http:server:port/context_root/tags/dir1/tag1. I always get a 404.

    In summation, I can't seem to link to the directory via symlink nor within the web app. I suppose it could be a bug, but seems like something that is somewhat common?

    In WASCE 3.0.0.0 or 3.0.0.1, there's no expanded app deployment, that means the application will be a packaged bundle after being deployed.

    One way to plugin your dynamical content is to add things to related runtime data location for the deployed application. (I can't remember exactly which one is.) The location is WASCE_HOME/var/catalina/work or WASCE_HOME/var/catalina/resources

    You can put your links there to have a try.

    Thanks for further info. I didn't end up needing to try that as I was able to resolve the problem by adding the following config options in the <wasce_install_home>/etc/system.properties file:

    org.apache.geronimo.tomcat.GeronimoStandardContext.allowLinking=true
    org.apache.geronimo.webapplication.stage=development

    Not everyone can run w/ the development option but for our purposes it was fine as we are running public data and simply keep it for tracking records.
