PushRegistery & ConnectionNotFoundException

[jascco]

Hi guys,

I want to create a midlet (S40 6th edition) that can be started from another midlet.
But I cannot figure out which connector should be used for PushRegistry registration.

I have code which tries to initialize PushRegistry dynamically. But when I call:
PushRegistry.registerConnection(url, midletName, "*");
ConnectionNotFoundException is allways thrown.

I have tried to use following url's:
datagram://ortNumber
socket://ortNumber
and they both give same result

Only url that works is sms://ortNumber, but I cannot use SMS to start my midlet

Is there anyway to get around this problem (like other url's I should use)?

Thanks

Which device have you tested this on? Does the device have network connection?
Do you have all the necessary permissions listed in the JAD file?
Can you provide the exact URLs you have tested this with?

Thanks for the reply Hartti,

I'm testing on C3-00.
Device has both 3G and WIFI networks connections available, and both seem to work (when using browser)
I have to try to add network permission, but I have javax.microedition.io.PushRegistry in JAD-file.
Should it throw SecurityException if permissions are missing?

I have tested with following URLs:
"socket://:5000" -> ConnectionNotFoundException
"datagram://:5000" ->ConnectionNotFoundException
"sms://:5000" -> this works

I have tried someother ports but allways same result

This Exception means
"ConnectionNotFoundException - if the runtime system does not support push delivery for the requested connection protocol"

I do not remember reading that Series 40 would not support network-related push connections, so maybe the network access is not properly set up for Java MIDlets. Could you try if network connection works for a simple HTTP Connection MIDlet (there are plenty of examples around....

Hi,

I tried simple HTTP Midlet and it works correctly.

I also did some tests with my N8 and my MIDlet works correctly in it. When I create network connection from another midlet my pushregistery midlet is started.

Could there be only some ports that work on S40 devices? (I did some test but any of random port from range 5 - 70000 didn't work)

Now I have also following permissions in my JAD-file:
MIDlet-Permissions: javax.microedition.io.PushRegistry,javax.microedition.io.Connector.http,javax.microedition.io.Connector.https,javax.microedition.io.Connector.datagram,javax.microedition.io.Connector.socket

Here's my code:

 
try {
      String dport = "datagram://:5";
      PushRegistry.registerConnection(dport, myName, "*");

      Alert alert = new Alert("REG OK", myName+":"+dport, null, AlertType.WARNING);
      alert.setTimeout(Alert.FOREVER);
      display.setCurrent(alert);
	   			
   } catch (Exception ioe) 
   {
       Alert alert = new Alert("Error", ioe.toString(), null, AlertType.WARNING);
       alert.setTimeout(Alert.FOREVER);
       display.setCurrent(alert);
    }

Any ideas ? =)

Hi,jascco
For doing your task,have you sign your MIDlet?
if yes then it should have signed by operator or manufacturer domain.

Hello jascco,

the list of supported protocols for Push Registry in Series 40 include the following:

-Bluetooth RFCOMM
-Bluetooth L2CAP
-SMS
-MMS

Unfortunately the other protocols are not supported.

This information can be found from the Java Developer's Library:

Java Developer's Library 3.10 > Developer's guides > Networking > Networking in Java ME

http://library.developer.nokia.com/i...505254584.html

Thanks r2j7,

That's what I was looking for, just couldn't find it =)

According to Developer's Library it applies to JRT 1.0.0, do all S40 devices come with JRT 1.0.0
or is there any S40 devices that could support newer JRT (which could have some other PushRegistry methos available)?

pradip7: I have not signed my midlet, but according to r2j7's post it wouldnät help =)?

Hello jascco,

you can find all the devices which support Java Runtime 1.0.0 for Series 40 by using the device search tool online by Nokia Developer web site: http://www.developer.nokia.com/Devic...vaRuntime1.0.0

Regarding the latest features on Java Runtime 1.0.0 for Series 40, you can find more information from Java Developer's Library:

Java Developer's Library 3.10 > Introduction to Java ME > New features in Java Runtime 1.0.0 for Series 40

Thanks again r2j7,

I allways forget that Nokia has created these great web pages for us =)

I'm going with solution found on link:
http://library.developer.nokia.com/i...5CC29F94F.html

-> S40 devices should support Content Handler API, which might solve my case

[hartti]

Thanks r2j7,

Funny that I went through the Nokia Developer Library materials looking for this information, but I was not able to find the note either. Odd..

the list of supported protocols for Push Registry in Series 40 include the following:

-Bluetooth RFCOMM
-Bluetooth L2CAP
-SMS
-MMS

And CBS and Bluetooth OBEX. Nevertheless jascco, this is not the answer you where looking for. In Series 40, there is a private API to call other MIDlets, however, because it is private and signing is involved, I do not know anything else.
