How to add a parameter to a URL in GWT?

I have a Java/GWT application. In that there is a list of items. If I click on any item title then that item is opened with full description.

I am using Anchor for the item title, so what I want is when user clicks on item title then in the URL the id of that item is appended to the current URL.

For example, this is my URL:

"http://127.0.0.1:8888/MyApp.html?gwt.codesvr=127.0.0.1:9997#listItem?list"

and I have to append id to the end of the URL like:

"http://127.0.0.1:8888/MyApp.html?gwt.codesvr=127.0.0.1:9997#listItem?list&itemId=55"

URIBuilder of Apache HttpComponents offers a convenient method to add parameters and will deal with existing query parameters and anchors.

Using Window.Location should do your trick : see the doc here

Something like this :

String url = Window.Location.getHref();
url = url + "&itemId=" + itemId;
Window.Location.replace(url);

Although of course, as Crollster pointed out, you should insert your url parameter before the # sign. Give more details on what you're looking for exactly (why do you have to add the parameter manually, does the page have to reload ...)

You see that # in the URL? Thats an anchor - you will need your parameter to be added before that, so it looks like this:

http://127.0.0.1:8888/MyApp.html?gwt.codesvr=127.0.0.1:9997&itemId=55#listItem?list

You can try with javascript coding.When the user clicks on link, get this URL and appends your id to it and reconstruct the URL.

you can use redirect command in order to add this parameter

response.sendRedirect(your url + itemId=55);

Then you can extract this variable.

I hope this will help.
