[jboss-user] [JBoss Portal] - how can we redirect from a portlet to a servlet ?

Monday, 26 May 2008

hello,

i am working on :
    - sdk 6,
    - seam 2.0.0 GA
    - Jboss portal 2.6.

I am trying to redirect from a portlet to a servlet view :

portlet controler :

  | 	
  | 	private String amount = "200";
  | 	private String devise = "euro";
  | 	
  | 	private PaiementController payCtrl = null; 
  | 	
  | 	public String getAmount() {
  | 		return amount;
  | 	}
  | 	public void setAmount(String amount) {
  | 		this.amount = amount;
  | 	}
  | 	public String getDevise() {
  | 		return devise;
  | 	}
  | 	public void setDevise(String devise) {
  | 		this.devise = devise;
  | 	}
  | 	
  | 	public PaiementController getPayCtrl() {
  | 		if (this.payCtrl == null) {
  | 			this.payCtrl = new PaiementController();
  | 		}
  | 		return this.payCtrl;
  | 	}
  | 	
  | }
