To get Code Assist for Seam specific resources in an externally generated project, you should enable Seam features in Project Preferences. Right click an imported project and navigate Properties > Seam Settings. Check Seam support box to enable all available Seam Settings.
To import an example Seam project from jboss-eap into your working directory, you should perform the following steps:
Go to New > Other > Java Project from Existing Buildfile
Point to the build.xml of any chosen project by pressing Browse button
Hit Finish to open the project
As these seam examples are non WTP projects, next you should enable Seam support for them. To do that, right click the project and go to Properties > Seam Settings.
You should right-click the project, select Properties > Java Build Path, then switch to the Source tab, select the output folder for src/hot ( src/main) and click Edit to change their output location.
