Plugins are not correctly deployed in webapp mode

• Key: FOR-735

Description

(At this point I didn't try this scenario step by step any more; basically it is what we did to setup the site, except that we copied our project data from forrest 0.6 before trying the pdf links)

- run forrest webapp to create an empty webapp
- configure Tomcat to run the webapp (we did it by creating a context descriptor and put it onder Tomcat's config directory)
- the pdf links give an error "Resource Not Found"

I have not investigated this but it sounds like plugins are not being correctly packaged in the WAR.

Changed subject to reflect the wider implications of this issue.

There is various discussion in the thread:

 "Using plugins with forrest as webapp"

[Ross Gardler]

The "webapp" target does not include the plugin files, but the "war" target does:

WORKAROUND:

Build the war file with "forrest war" and deploy that instead. Your servlet engine should unpack it when it is first used, but you could always unpack manually if necessary.

[Gunther Sablon]

I ran forrest war, and then manually moved the build/plugins directory into the root directory of each of our forrest webapps..
Restarted Tomcat and... it works!

Thanks!

Can it be because the plugins got downloaded even we have them on the hard drive?

[Ross Gardler]

The problem is simply that the plugins are not located in the war file in a place Forrest expects to find them. They are not downloaded when running a war, ony when building a war. And even then they are only downloaded if they are not already present on the local machine (either in build or in the plugins src directory.

To get it running (forrest-0.7-377981, tomcat 5.5.15)

1. Adapt web.xml, see http://tinyurl.com/cn5ep (Mail archive)
   Now Forrest runs and produces some output but *not a single*
   plugin works.

2. Copy Forrest-0.7/build/plugins into the webapp dir and change
   the plugins entry in
      webapps\my-project\WEB-INF\xconf\forrest-core.xconf
   to
     <plugins>@context.home@/plugins</plugins>
   as described in http://issues.apache.org/jira/browse/FOR-403

Note: you must run Forrest first to get the plugins you need into the forrest/build directory.

[Johannes Schaefer]

seems to work in 0.8, too.

it's better to create a war-file using 'forrest war',
this will include the plugins (see Ross' comment above)

step 2 needs to be then
  <plugins>@context.home@/build/plugins</plugins>
