[jboss-user] [JBoss Seam] - Component.getInstance and 64bit java

[Stankar]

Hello,

I have custom servlet,  when I call


  | 209: PictureShowAction psa = (PictureShowAction) Component.getInstance(PictureShowAction.class);
  | 210: Picture mi = psa.getImage(idLong);
  | 

in this servlet, I get sometimes null value into psa variable.

On my developer notebook (32bit java, tomcat 6.0.10) all works fine, on server (64bit java, tomcat 6.0.13) I get sometimes NullPointerException.

Exception:
java.lang.NullPointerException
