Re: Send data (keep alive probe) across GWT RPC connection

I have a web application running on an Amazon server using a Elastic load balancer and when I make a RPC call between my client and the server it is timing out after 1 minute, because there is no activity on the RPC connection for more then a minute. The reason there is no activity on the connection is because the process invoked by the client takes 2-3 minutes to run on the server. I have 2 solutions to this problem which are 1) have amazon increase the idle timeout to 2-3 minutes, or 2) send data ever 50 seconds over the RPC. I am in the process of getting Amazon to increase the idle timeout, but in the meantime does anyone know how to do option 2. I know how to send a message every 50 seconds between the client and server after the RPC is made, but this does not solve the problem because the message is not sent across the original RPC connection and it has to be in order to keep the connection up. I'm new to GWT and JAVA and don't know if option 2 is even doable, but I would really appreciate any suggestions or help with this that anyone can give me.

I doubt option 2 is doable: sending any data (e.g. from the server to the client) would likely break decoding of the response on the client-side.

You have option 3 though: have your server spawn the processing in an asynchronous task and respond early to the client (if possible, you could also possibly wait for the task to complete, but no more than 50 seconds; if it's shorter then you'll send the task result right to the browser, otherwise you'll tell the browser that it's being processed asynchronously). The client then makes another request for the status of the task.

This is a major refactoring though…

Re: The method isCompleteHtml(String) is undefined for the type SafeHtmlHostedModeUtils

isCompleteHtml is public since 2.5.0. Make sure you don't have some pre-2.5.0 libraries (e.g. gwt-servlet.jar) in your classpath that could conflict with your updated GWT 2.6.0 libs.

There must be other errors up in the log. There's a reason why deferred binding failed.

To change the property of .cellTableEvenRow , .cellTableOddRow in
CellTableStyle.css. Inject your CellTableStyle.css in client side
code.

//client side code
interface TableResources extends CellTable.Resources

Re: How to access a web page in Frame

Perhaps you have cross domain problem. Is URL in your iframe from the same domain as main application? If not you need something like proxy servlet to simulate you getting data from your server side.

If you need that more often then you should probably extend GWTs Frame class and make a public method to access the content document.

Keep in mind that you should wait until the frame is loaded using frame.addLoadHandler().
