[Resolved] How to open a file from Alfresco without authenti

[unknown-user]

Hi All

I am using a hyperlink in my jsp page. when i click on this link, it opens a new window and connect to the alfresco server. I want to open a file directly which exists on Alfresco server. For achiveing this functionality, I am using URL Addressability.
Now i can open the file directly from alfresco server . Before showing this file, it's showing alfrseco web client screen for authentication.after entering username & password only, it is showing the file.I want to open this file without alfrseco web client authentication screen.

To overcome this authentication screen problem, i am passing ticket id with the URL in the below code but still it is not working.
See the error after the code–

Code
public String searchAndDownload(){

WebServiceFactory.setEndpointAddress("http://localhost:8080/alfresco/api");
AuthenticationUtils.startSession(USERNAME, PASSWORD);
—————————————————————
————————————————————–
ticket = AuthenticationUtils.getTicket();
—————————————————-
—————————————————
String url = "http://localhost:8080/alfresco/d/d/workspace/SpacesStore/'+nodeId+'/'+file+'?ticket='+ticket;
return url;
}

Error

Hi All

Now If i pass ticket id with URL then it is showing authentication screen and then it is not taking "admin" as a username and "admin" as a password.
if i use URL without ticket means like http://localhost:8080/alfresco/d/d/workspace/SpacesStore/'+nodeId+'/'+file
then only it takes username & password.
