Re: [Dev] [UUF] [IS] Invoke an OSGI service from a client side JS

[SajithAR Ariyarathna]

Hi Indunil,

Can you explain your exact requirement? Seems that what you want to do is,
save some data (obtained in a HTML form) using an OSGi service in a form
POST submit.

If so, then you can do this in the onRequest function. Don't specify any
'action' for your HTML form, so when you submit it the POST request goes to
the same page (URL). In the onRequest function of your page, you can check
whether the request is a POST or not with env.request.method == "POST"
condition. If that condition is true, then you can extract POST parameters
from the request and call the desired OSGi service.

e.g.

function onRequest(env) {
if (env.request.method == "POST") {
// this is a POST request, so lets call the OSGi service
callOSGiService("org.wso2.Foo", "barMethod", ["some", "parameters"]);
// more stuff you want to do ...
}
}

Please refer the file upload sample [1][2] in the "Feature App" sample (URL
https://localhost:9292/Features-app/file-upload).

Thanks.

[Dev] [UUF] [IS] Invoke an OSGI service from a client side JS

[Indunil Upeksha Rathnayake]

Hi,

As mentioned in the Web App Developer’s Guide for Unified UI Framework [1],
"callOSGiService" is a function call of a server side JS API. So that
AFAIK, that can't be called from JS files in the public folder, where
client side logic resides.
I have requirement to call an OSGI service from a client side JS. Is it a
way to do that using UUF?

Following are the steps of the exact requirement.

   1. Invoke an OSGI service in onRequest() and will be filled the content
   of .hbs from the value returned in onRequest().
   2. Have a "submit" button in .hbs, where the onClick function is been
   implemented in a JS resides in the "public" folder.
   3. Inside the onClick function, need to call another OSGI service.

Without implementing the onClick function in "public" folder, is there any
other way to achieve that and call the OSGI service?


And I would like to know how the "module" function works? Is that cater our
requirement? Included module will be executed before the onRequest() method
or after? Please share if there are any sample using the module function.
