Re: [xmlblaster] Pinging the server using Applets

Eduardo Catarino wrote:


When using an Applet how can I check if an established connection went down? (for example if the server is disconnected or if for some reason the communication channel is interrupted) I’m trying to write a ping function to detect this case every 5sec and I used the isConnected() method, however in the situation that the server was up and suddenly was force to go down this function doesn’t detect this situation. Does anyone know how to overcome this problem?

Best regards,

I have added such a ping method, please checkout from svn,
you'll find an example in





* Returns "/qos/state/ at info"="OK" if communication from servlet to xmlBlaster is OK
* <br />
* Returns "/qos/state/ at info"="POLLING" if communication from servlet to xmlBlaster is down but polling
* <br />
* Returns "/qos/state/ at info"="DEAD" if communication from servlet to xmlBlaster is permanently lost
* at return never null, contains QoS in XJPath format
public Hashtable ping(java.lang.String qos) throws Exception;
