Hello,
I am trying to deploy my project under cocoon. I change my project properties and I set my web context root as : /cocoon/project1 instead of /project1. Then I try to deploy it, I select the project ( exploted archive ), and the server ( tomcat 5 ) and I get NOT VALID as “deploy location”.
It is critical for me use Cocoon. It there someway to fool my eclipse ?
Please help,
JesusThe multi-segment context-root restriction you are encountering is due to the fact that MyEclipse exploits the automatic deployment capability of most appservers which does not allow multi-segment context-roots. If you absolutely required a multi-segment context-root then you must resort an appserver specific deployment extension. For Tomcat this implies manual modification of the server.xml or the newer Tomcat5 context-descriptor http://jakarta.apache.org/tomcat/tomcat-5.0-doc/deployer-howto.html.
Explanation:
The convention used by the appservers is to designate a special directory under which all packaged and exploded archives reside, e.g., <tomcat>/webapps. All contents of this directory are assumed to be J2EE applications (WAR, JAR, EAR) either in packaged or exploded archive form. Since WARs can not directly specify their context-root, the auto-deploy convention of the appservers is to use the name of the WAR archive or exploded WAR directory as the application’s context-root. MyEclipse uses your web project’s context-root as the archive name for both deployment forms. For example if myProject’s context root is /foo then the exploded deployment to Tomcat will mirror myProject to <tomcat_home>/webapps/foo. Here is the crux of the multi-segment context-root restriction. The extra segments in the context-root translate to pushing the root directory of an exploded web project into a subdirectory under appserver’s auto-deployment directory. This violates the deployment convention of the appserver and thus the server will not deploy your app. A similar problem applies to packaged deployment since the multi-segment path can not be converted to the name of archive.I hope this is not too confusing. At this time MyEclipse takes a conservative approach to deployment and relies on conventions and standards for 90% coverage of most deployment scenarios. We will evaluate other options over time for even better coverage.
Sorry for the long note.

MyEclipse SupportSo, that means that in Tomcat myEclipse can only can deploy under the folder /webapps ? So if I need to process XML pages with a engine like cocoon what can I do ? Is there some way to fool my eclipse and deploy the application under a different directory ?
JesusDeployment locations other than <tomcat_home>/webapps require explicit modification of Tomcat’s server.xml file. You can configure the Tomcat server.xml to deploy your project directly from your project’s web-root directory. Doing this gives you the option to use a multi-segment context-root also. If you use this process do not use MyEclipse deployment for this application since it may conflict with your manual configuration, i.e., non-unique context-root exception or other problem.
Note: if you want to manually override the deployment location please submit this as an enhancement request. I know that development discussed this at length and retracted the functionality due to support concerns since it is so easy to mess up a deployment if you don’t know all the details. Note they will probably not concede to modifying application server specific files since the consequence of dorking such a file is a total server crash and because servers are so different in how and when they can be configured [static vs runtime].
