I’m having problems with the robot actions, it only responds to the WAVELET_SELF_ADDED event, it even don’t works with the BLIP_SUBMITTED event included into the application.

I’m trying to develop a WAVELET_PARTICIPANTS_CHANGED event listener, but I don’t get it. I’ve defined the bean inside the applicationContext.xml, and inside the class I’ve copied the OnSelfAddedListenerImpl.java code (because it works).

In the application logs, when the WAVELET_SELF_ADDED is generated i have two entries:

07-06 02:28AM 35.226 /_wave/robot/jsonrpc 200 29ms 38cpu_ms 0kb WaveRobotGateway
07-06 02:28AM 35.120 /_wave/capabilities.xml 200 15ms 19cpu_ms 0kb WaveRobotGateway

But when I change the wave participants, there is no new logs.

This is the capabilities of my robot:

0
0.21

I don’t know where the error is, somo ideas? Maybe the issue is about the Google Wave API version.

Thanks!

The gadget can communicate with any server side application.
With the deployment of the bot there are sources included that demonstrate how the gadget can call your server and the server replies with data in JSON format.
Once you receive the data you can make changes in the gadget.
The server side sample file that handles the request for the gadget is

src/main/java//your/package/gadget/handler/impl/GadgetServiceImpl.java

To invoke your service which is actually configured with spring at

/war/WEB-INF/conf/applicationContext.xml

You can simply use some javascript with jquery for a jsonp request similar to the one below.

urlParams.push(“param=” + value);
$.getJSON(
“yourgadgetdeploymenturl” + “?” + urlParams.join(“&”) + “callback=?”,
function(data) {
//doSomethingWithData
);
}

We bundle com.withwaves.commons.utils.view.JSONPSupportView with the generator so you should have a View generator in your bot that already supports the callback replacement for JSONP.

You can use the same technique with any other server that you’d like to fetch data from that supports jsonp, for example ebay.

Let us know if you have any more questions and glad you found the generator useful.

I have a question about bot-gadget communications: I have a Wave Bot, working and all fine, and I have a Gadget, also working fine (built using the generator from this page…). What I want is to initialize the gadget from within the bot with data I have for it. Basically the end result I’m aiming to is something like your ebay bot, where the participant types something, and the gadget is added with contents (search results in that case) relating to what was typed. I couldn’t find a way to do that, but I’m probably missing something trivial… am I?

thank you

For the maven archetype wizard just type anything. The generated project contains the source code that you can modify to not actually call the alchemy api.
OnBlipSubmittedListenerImpl (lines 31-40)

Anyway to set it up without downloading the jar, pom files again unless there’s an update?
