Gwt demo

[ylcoca]

No i have not change the name of the java class and yes the reference to the compiled module js is correct!I also came to conclusion that it is not being connected to the server but don't know why.

Hi ylcoca,

I can confirm that from your description we can conclude that the demo stops before contacting the Lightstreamer server. The issue is with the servlet container that fails to execute the GWT code.

To understand why we should proceed with further investigation:
- Could you confirm that your servlet container runs under Eclipse?
- "GWT Compile project" completes successfuly?
- Which version of the Google plugin is in use?
- Could you report the contents of the browser console?

Thank you,
Giuseppe

Although there is some doubts i have how do i know the lightstremer server for this demo is running ,I think probably I'm not properly starting the server or not setting up things properly to conectem alltogether

Hi giuseppe

Got it to work , I’ll make a quick chronology of what I did from scratch
I downloaded the Lightstreamer_Moderato_5_1_1_Colosseo_20130305 and I tried first the demo that ask for this :
get the lib from here:
<Lightstreamer HOME>\DOCS-SDKs\sdk_client_javascript\alternative_libs\
and copy the file named lightstreamer_globals.js into the war/lightstreamer
but never got it to work don’t know why
then I tried the one that says
extract the files included in the
Lightstreamer/DOCS-SDKs/sdk_client_html/lib folder and copy them into the
war/lightstreamer folder of this project.
But the Moderatto I had downloaded didnt had the sdk_client_html folder which have some very important js files that are the ones that makes the connection to the server that was why I couldn’t connect to the server ,I finally downloaded that folder and added the files ,started the lightstreamer server ,and voila and it worked!

Thanks for the help and quick response

Hi ylcoca,

I am pleased that now the demo works.
I confirm you that the two versions of GWT Stock-List demo refer to two different client libraries for Lightstreamer: one is for the brand new Lightstreamer JavaScript Client API 6.0 supported only by Lightstreamer server 5.0 or newer, the other is for Lightstreamer HTML Client API 5.0 that can run both on Lightstreamer server 4.x or 5.x.
Since the 4.x server will soon no longer supported it is important that you're running a 5.x version of Lightstreamer server, preferably the latest version 5.1.1.

However, it is a great pity that you were not able to run the demo with the new JavaScript library for Lightstreamer.
I just have a doubt about why it not work, when you copied the file lightstreamer_globals.js you should synchronize the name with that referred in GWT_StockListDemo_Basic.html in this row:

<script src="lightstreamer/lightstreamer.js"></script>

Anyway, thank you for the feedback.

Hi giuseppe ,
That was exactly it I changed the reference of the js file from

<script src="lightstreamer/lightstreamer.js"></script>
to
<script src="lightstreamer/lightstreamer_globals.js"></script>
and that was it
Thanks a lot
