Navigation from a Work Item to other Website

Desktop desktop=Desktop.getDesktop();
                    try{
                        desktop.browse(new URI("www.google.com"));
                    }catch(Exception e){
                        e.printStackTrace();
                    }

Is that your working version?

Yes.
When i save a workitem, i will get workitem id.
As soon as i got the workitem id i need to pass it to my web application to retrieve all the contents in my application and modify the WI using oslc

Then the snippet above does not make that much sense to me.
If this is on a work item save

1. You should use a Follow Up Action, because you want to modify the work item.
2. You would not browse to that page, you would use REST calls under the cover, invisible to the user and perform your modification in a second save.
3. Please note, if you try to use an advisor instead: https://rsjazz.wordpress.com/2012/12/14/do-not-modify-the-triggering-element-in-an-operationadvisor/
   

Hi Ralph,

I will explain my scenario.

I created a new task in ALM by entering the attributes.
On click of save, task is created as well as a new task has to get created in my custom web application.

To do this, on click of save , i took the WI id and pass it to my application.
From the URL , i will pick up my id and through OSLC i query the values which i entered during the creation of task in ALM and display in my application.

User will press save so that all the values also will get save in my application also.
This will reduce human effort of entering data twice.

Suppose, if user changes somethings in my application, i will update the WI using OSLC.

This is mainly to have sync with both the tools.

Regards
Chandan
