Hello,

we are trying to redirect from a controler portlet to an website like www.google.fr or a servlet.

We are working on :
- sdk 6,
- seam 2.0.0 GA
- Jboss portal 2.6.
- protletBridge 1.0.0.B2
- richfaces.

I am trying to redirect from a portlet to a servlet view. So, I have a session bean. This session Bean is the portlet controler, and has an subcontroler. The subcontroler has the responsability to redirect to an external resource.

We invoque the method of the subcontroler with a <h:commandButton/>.
But an java.lang.IllegalStateException is throwed.

java.lang.IllegalStateException: sendRedirect cannot be called after setPortletMode/setWindowState/setRenderParameter/setRenderParameters has been called previously

i have tryed several ways to redirect :

FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
externalContext.redirect("http://www.amazon.com/exec/obidos/ASIN/0596005393");
facesContext.responseComplete();

FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
ActionResponse actionResponse = (ActionResponse) objresp;
actionResponse.sendRedirect("http://www.amazon.com/exec/obidos/ASIN/0596005393");

FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
JBossActionResponse objresp = (JBossActionResponse) externalContext.getResponse();
objresp.sendRedirect("http://www.amazon.com/exec/obidos/ASIN/0596005393");

So, i have tryed to launch the redirection by an ActionListener. In this case, the same exception is appeared.

I need to know :
- my code is wrong ? in this case, what is the correct way to redirect ?
- this is a limitation or a bug of portlet bridge ? So, do you fix it ? and can you give us a date ?
- are they alternate solutions ?

I am disappointed. Indeed, with Liferay, it is really easy to redirect to an external resource. Liferay give us tools to do it. But, with portal + seam + portlet bridge, it seems terribly difficult.

I give you all details :

portlet controler :

@Name("testControler4Buy")
@Scope(ScopeType.SESSION)
public class TestControler4Buy {

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;
}

}

SubController :

public class PaiementController {


public void listen(ActionEvent event) {

FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();

try {
JBossActionResponse objresp = (JBossActionResponse) externalContext.getResponse();
objresp.sendRedirect("http://www.amazon.com/exec/obidos/ASIN/0596005393");
}catch(IOException e) {
e.printStackTrace();
}



}

public void goToPaiementView() {

FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();



try {

if (objresp instance of JBossActionResponse ) {

JBossActionResponse objresp = (JBossActionResponse); externalContext.getResponse(); objresp.sendRedirect("http://www.amazon.com/exec/obidos/ASIN/0596005393");
}
}catch(IOException e) {
e.printStackTrace();
}

try { externalContext.redirect("http://www.amazon.com/exec/obidos/ASIN/0596005393");
facesContext.responseComplete();

} catch(Exception e) {
e.printStackTrace();
e.toString();
}

}
}

Portlet View :
