Flash Builder 4.5 and Deploying to Tomcat 6
When using Flash Builder 4.5.x with Eclipse Helios, if you try and deploy your integrated Flex and Data Services project to Tomcat 6, you get the following error being reported:
The server does not support version 3.0 of the J2EE Module
The quickest and easiest way to allow for deloyment onto Tomcat, is to:
- Find your Project folder on the file system
- Open up “project_loc/.settings/org.eclipse.wst.common.project.facet.core.xml”
- Change the value for <installed facet=”jst.web” version=”3.0″/>, to <installed facet=”jst.web” version=”2.5″/>
- Save the file, refresh your Eclipse project, and you are good to go.
You can then deploy your project onto Tomcat 6
