Hello,
since yesterday I have this publish-exception in my java software (paho based) on tomcat:

MqttException (0) - java.io.FileNotFoundException: /Library/apache-tomcat-7.0.11/bin/applicationStatus6-tcp9524030961883/s-2.msg (No such file or directory)

the folder applicationStatus6-tcp9524030961883 (where applicationstatus6 it's the client-id) doesn't exist, if I make it manually the application works.
It's strange because i hadn't this error before.
Of course when I restart the connection the framework deletes the folder. could be a permissions problem?
How can I fix it?
thanks
marco

Hi Marco,

It seems like a permissions issue in creating the directory.

You said you created the directory and then it worked; were you able to create it as the same user tomcat runs as, or did you have to use root?

You could tell the client to use a different directory entirely for the persistence data by:
1. create your own instance of MqttDefaultFilePersistence passing in your desired directory to the constructor
2. pass this instance of persistence to the appropriate MqttClient constructor.

Hope that helps,

Nick
