Hello,
her is my solution tot he problem above, solved with JBoss Seam and Facelets
1.) First I follow the discription
http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossSeamGettingStartedGuide and installed JBoss
IDE and SEAM as described.
2.) Now the steps in Eclipse for an new ?Enterprise Application Project?
Project Name: statelessSb
J2EE Modules -> New Module: statelessSbEJB, statelessSbWeb
The Workspace is defined as V:\seam-workspace
Under Win CMD type as follow: (the same like 1.)
V:\seam-workspace\jboss-seam-1.0.1.GA\seam-gen>seam new-wtp-project statelessSb
V:\seam-workspace\jboss-seam-1.0.1.GA\seam-gen>seam new-stateless-action statelessSb
StatelessCalculator
V:\seam-workspace\jboss-seam-1.0.1.GA\seam-gen>seam new-action-page statelessSb home
StatelessCalculator
Now Refresh statelssSb, statelessSbEJB and statelessWeb in Eclipse and set ?Configure
Buildpath? from statelessSbEJB (also see in 1.)

| public String doAction();
|
| //add additional interface methods here

|
| public String getResultString() {
| return resultString;
| }
|
| public void setResultString(String resultString) {
| this.resultString = resultString;
| }
|
| }
|
Finally ADD the Project to JBoss Server, start and see the result by typing
http://localhost:8080/statelessSb in browser
Have fun
