Touchkit addon - The server cannot be reached

Flow
1

Hello,

I have problem with touchkit addon.
Touchkit has OfflineModeEntrypoint class. In that class is timer scheduled for 5 seconds and after that if applicaiton didn’t start the followed message is shown:
“The server cannot be reached
The application didn’t start properly”
Could someone please tell me what should I do to increase this time or disable this message?

Best regards,
Lukasz

Unfortunately the 5 second timeout is not directly configurable. What you can do though, is use
GWT’s deferred binding
 and replace the entry point with your own custom class. So, in your *.gwt.xml, do something like:

<replace-with class="com.example.client.MyCustomOfflineModeEntrypoint">
    <when-type-is class="com.vaadin.addon.touchkit.gwt.client.offlinemode.OfflineModeEntrypoint" />
</replace-with>

And then implement MyCustomOfflineModeEntrypoint with whatever timeout you prefer.

Thank you fo reply.
I have alredy tried this and this didn’t work and I don’t know why.

I tried to do this in two ways.
Common file is MyCustomOfflineModeEntrypoint (except package which wolud be change):

[code]
package com.vaadin.addon.touchkit.gwt.client.offlinemode;

import com.google.gwt.core.client.EntryPoint;

public class MyCustomOfflineModeEntrypoint implements EntryPoint {

@Override
public void onModuleLoad() {
    System.out.println("Here I am!");
}

}
[/code]1)
In my *.gwt.xml I added:

<replace-with class="com.example.client.MyCustomOfflineModeEntrypoint"> <when-type-is class="com.vaadin.addon.touchkit.gwt.client.offlinemode.OfflineModeEntrypoint" /> </replace-with> And I have following error during building:

In my *.gwt.xml I added:

<replace-with class="com.vaadin.addon.touchkit.gwt.client.offlinemode.MyCustomOfflineModeEntrypoint"> <when-type-is class="com.vaadin.addon.touchkit.gwt.client.offlinemode.OfflineModeEntrypoint" /> </replace-with> During project building I got following message:

[INFO]

    [ERROR]
 Could not find module entry point class 'com.vaadin.addon.touchkit.gwt.client.offlinemode.OfflineModeEntrypoint'

Do you have any idea why these errors are shown?

With deferred binding you always have to extend the class you’re replacing, just implementing the same interfaces isn’t enough. Sorry if I was unclear on that earlier. So, instead of public class MyCustomOfflineModeEntrypoint implements EntryPoint { do this:

public class MyCustomOfflineModeEntrypoint extends OfflineModeEntrypoint { Then it should compile just fine.

As for the package names, they shouldn’t matter as long as the class is in the source path of your module. If I were you though, I’d use the default source path which is the
client
 package inside the package your *.gwt.xml file is in.

It works!
Thanky you very much for help :slight_smile:
