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).
