You have to import project, not create a new one. In my case project is simple dynamic web project with one java class Report.java: package test; public class Report { private String value; public Report() { } public void send( int value) { } } and seam-beans.xml: <?xml version= "1.0" ?> <beans xmlns= "http: //java.sun.com/xml/ns/javaee" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation= "http: //java.sun.com/xml/ns/javaee http://jboss.org/schema/cdi/beans_1_0.xsd" xmlns:s= "urn:java:ee" xmlns:r= "urn:java:test" > <r:Report> <r:valueBroken> </r:valueBroken> <s:parameters> <s: int /> </s:parameters> <r:send> <s:Produces/> <s:parameters> <s: String /> </s:parameters> </r:send> </r:Report> <r:Broken> </r:Broken> </beans> If you import this project into fresh workspace, clean the project, there are no errors found. However, if you edit seam-beans.xml and save it, 4 errors found are correctly found.
