[jboss-user] [JBoss Seam] - Worst possible situation

[yuriy_zubarev]

Greeting,

The subject line is grim but true. I was developing Seam app on Windows box and everything worked fine, I put it on a Linux box and it doesn't work and doesn't spit out any exceptions.

Ok, a bit of details. I use Seam 2.0.1 and tomcat 6 on Java 5. Windows and Linux environments have the very same versions of all components. When I started debugging this problem I created a very simple TestWidget entity with two pages to see the list and details for test widgets.


  | @Entity
  | @Table(name = "test_widgets")
  | public class TestWidget implements Serializable {
  | 
  |   private int id;
  |   private String name;
  | 
  |   @Id
  |   @GeneratedValue
  |   @Column
  |   public int getId() {
  |     return id;
  |   }
  | 
  |   public void setId(int id) {
  |     this.id = id;
  |   }
  | 
  |   @Column
  |   public String getName() {
  |     return name;
  |   }
  | 
  |   public void setName(String name) {
  |     this.name = name;
  |   }
  | }
  | 

TestWidget class is coming from a maven sub-project and the generated JAR also includes persistence.xml:


  | persistence.xml
  |

  | <framework:entity-query name="testWidgets" ejbql="select w from TestWidget w" />
  | 


  | @Name("testWidgetHome")
  | public class TestWidgetHome extends EntityHome<TestWidget> {
  | 
  |   @Factory("testWidget")
  |   public TestWidget initModule() {
  |     return getInstance();
  |   }
  | }

When I run the app on a windows box everything works. When I run it on a Linux box, I can create widgets and see the list of widgets but when I click to see details of a particular widget, I get a screen with no details information. The screen looks like as if I'm trying to create a new widget. #{testWidget.id} shows "0" and "name" textbox is empty. No exception or warnings in a log file. I'm totally puzzled. This is a very basic set-up and everything works fine on a Windows box.

Any clues would be highly appreciated.

Thank you,
Yuriy
