i learning seam framework , going through examples given seam package. trying declare property in seam component , refer in jsf. but, getting error saying class not have property.
my seam component follows:
register.java interface
package org.jboss.seam.example.registration; import javax.ejb.local; @local public interface register { public string register(); } registeraction.java class
@stateless @name("register") public class registeraction implements register { private string college; public string getcollege() { return college; } public void setcollege(string college) { this.college = college; } register.xhtml file
<h:inputtext id="college" value="#{register.college}" required="true"/> while deploying application , accessing link: http://localhost:8080/seam-registration/register.seam
i getting below error:

the exception speaking itself, seam proxy class , mapp interface result #{register} value expression refers interface not contain getter/setter college field. don't need use ejb of time remove interface , use class only.
@name("register") //or better @name("registeraction") @scope(conversation) public class registeraction { private string college; public string getcollege() { return college; } public void setcollege(string college) { this.college = college; } }
