Re: UDP packets & GWT
For an update, what I did is output the data to an xml file on the server, then fetch the data with a simple http GET using RequestBuilder. To deal with SOP, I had to put the xml file on the same domain as my shindig container. Thanks for the help, it is always appreciated.

UDP packets & GWT
Greetings, I know this is not a pure GWT question, but a related one. I have a web device that continuously sends UDP packets to a specific IP and port. I have a java application that is able to listen to the port and receive the packets. What I want to do is create an OpenSocial gadget in GWT that will somehow take the data and be displayed in the gadget. I understand that I am not able to use the java.net.DatagramSocket and java.net.DatagramPacket classes in GWT because javascript does not support socket listening. Anyone out there have a simple solution that would enable me to get the datagram data somehow. I would appreciate any suggestions.

Re: Character encoding issue with my gadget
I finally figured it out, It's actually an opensocial issue. The data being posted on an opensocial container is sanitized to prevent malicious code injection. Problem resolved by using: URL.encodeComponent(newText.getText()) URL.decodeComponent(text) Now I know :) Andre --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Character encoding issue with my gadget
Thanks Paulo and HW for the reply. I already have the Eclipse workspace setup to use UTF-8. Any other ideas out there?

Character encoding issue with my gadget
Greetings, I have researched this issue a lot and tried many potential solution to no avail. Here I am requesting your help. I have a opensocial gadget that is deployed in a Friend Connect container, where text is captured using the following Java code (GWT v1.6.4, Eclipse v3.4.2): String text = newText.getText(); and is later displayed in a FlexTable using the following code: textDisplay.setText(0, 0, text); My problem: Whenever some specific characters are inputed in the gadget, they are displayed in the FlexTable in an encoded form, for example: " (quote) displays: " ' (single quote) displays: ' & displays: & The problem is consistent in all browsers I have tried (FF, IE, Opera, Chrome). It is important to note that I have no problem with French specific characters é, à, etc. My XML & HTML file are set to UTF-8 encoding, and Eclipse is configured to use UTF-8 encoding. I specifically verified that each Java files are also encoded in UTF-8.

Re: Testing gadgets during development
Thanks for the reply. However, I found what I was looking for with the Eclipse plugin OpenSocial Development Environment (OSDE). http://code.google.com/p/opensocial-development-environment/ Andre On Fri, Jun 5, 2009 at 10:39 PM, Eric Ayers wrote: > The gwt-gadgets library (http://code.google.com/p/gwt-google-apis will > allow debugging in hosted mode, but unfortunately does not support the open > social spec for gadgets yet. > > -- > Eric Z.

Testing gadgets during development
Hello,
With the objective of learning more on gadget development, I am currently
modifying the StockWatcher Tutorial code to make it work in Orkut as a
social gadget (opensocial-0.8) using Eclipse 3.4.2 with GWT 1.6.4 &
GWT-gadgets. I got the first portion to run in the Orkut sandbox.
It is my understanding that it is not possible to test in hosted mode when
developping a gadget ("run as web application"). However, I would like to
know if there is an easier way to test changes, other than copying the
relevant files to a web accessible folder and adding the gadget (XML file)
in the Orkut sandbox.
Thanks for the help,
Andre
