Hey guys
I'm working on a project with Google App Engine. To get Data from my
devices we're using MQTT. The org.eclipse.paho.client.mqttv3.* library
starts a Thread with "client.connect()". After some researches i found that
you cant just simply create Threads when working with GAE. Following error
is shown:
*java.security.AccessControlException: access denied
("java.lang.RuntimePermission" "modifyThreadGroup")*
I continued searching and someone told to use following code instead of a
"normal" Thread:
*Thread monitoringThread = ThreadManager.createThreadForCurrentRequest( new
Runnable() {..}*
So i decompiled the paho library, looked up where the Thread is created and
changed it. I created a new class exported it as mymqttclient.jar In
eclipse i changed the order of my build at Properties -> Java Build Path ->
Order and Export so mymqttclient.jar is loaded before the
mqtt-client-0.4.0.jar So that it will use my created function with the
monitoringThread.
But how can i change the order of the .jar's in the web-inf/lib ?
Thank you very much for your answers, i couldnt find something useful until
now.
