Hi, I try to invoke portlet from JBoss Portal and I keep receiving an exception org.Jboss.Portal.wsrp.core.OperationFailedFault. And this is the stack trace: Exceptions at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall) at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters) at Pavonis.Wsrp.Proxy.WSRP_v1_Markup_Binding_SOAP.getMarkup(getMarkup getMarkup1) in C:\WSRP\WsrpViewerControl2005\WsrpService\WsrpProxy.cs:line 601 at Pavonis.Wsrp.WsrpService.wsrpGetMarkup() in C:\WSRP\WsrpViewerControl2005\WsrpService\WsrpService.cs:line 1525 A first chance exception of type 'System.Net.WebException' occurred in System.dll A first chance exception of type 'System.Web.Services.Protocols.SoapException' occurred in System.Web.Services.dll A first chance exception of type 'System.NullReferenceException' occurred in Wsrp.Service.dll A first chance exception of type 'Pavonis.Wsrp.WsrpServiceException' occurred in Wsrp.Service.dll I still can get the list of Remote Portlet offered by JBoss Portal like Weather Portlet or News Feed, Test Portlet etc, but none of them can display because I can't get the correct Markup. Any idea that I can fix it. Thank you very much. PS: I'm using an example of writing WSRP Consumer from MSDN Magazine and it works well with Portlets from NetUnity website, but not from my local Jboss Portal.
