Hello!

I am developing a kind of content management system. Uploading files with the cms will generate folders with these content in the webapp directory. When i republish the webapp all created folders and the content is deleted.

Is it possible to exclude some files/folders from deletion while republishing a webapp?

I am using eclipse Galileo and Web Developer Tools 3.1.1

Thanks
Tarek

Server publishing is designed to keep the published project synchronized
with the project in the workspace. If something exists in the published
project that doesn't exist in the workspace project, it assumes you
deleted it from the workspace project and therefore deletes it from the
published project. I don't know of any way to work around this behavior.

Cheers,
Larry

Hi Larry,

thanks for the fast answer. The tools do their synchronzing jobs very good:-) But we are developing an uploading tool which generates some gigs of jpegs and movies which must be downloadable within the same webapp. We dont want to put this data in our workspace project.
Do you have a hint were i can start hacking/changing the publishing? We just changed from old eclipse 3.3 with sysdeo tomcat plugin to 3.5 with WTP and we dont want to go back.

Regards
Tarek

If you grab source for the org.eclipse.tomcat.core plug-in and start
with PublishOperation2.publishDir(). This method is responsible for
publishing the web content of the project when the Server Location is
configured for the default "Use workspace metadata(...)" and "Serve
modules without publishing" is not enabled. I suspect
org.eclipse.wst.server.core.util.PublishHelper is the class that will
need hacking.

An alternative that is more Servlet Spec compliant is to store the data
external of the web application and provide a servlet that can serve the
content from the external location.

Cheers,
Larry

Thanks!

I had the same issue. I had the application create the set of folders
and content "beside" the main project

TomCat/webapps/mainproject
TimCat/webapps/foldersystem

Since "foldersystem" is not part of he project within Eclipse, then it
is not touched. yet Tomcat can see it as it is in its webb application
system.

@Larry: why is this not Spec compliant?

Thanks for the hint! I will have a look if this works with our application, too.

The Servlet Spec only says guarantees you can deploy a WAR to the
servlet container and it will serve it. It makes no guarantees about
how the web application will be served. Serving the web application via
the file system is not required. This is why
ServletContext.getRealPath() is allowed to return null. By making your
web application self-modifying, you may be creating portability and
security issues. It would depend on your use case how much these mattered.

Cheers,
Larry

Hi Larry,

Thanks
