If you are using Device Manager server to change the bundle list URL, make sure the following is in your config.ini file:
com.ibm.rfid.bundle.loader.bootstrap=true
When this property is set to true, the bundle loader copies its relevant system properties into ConfigAdmin so that a Device Manager server job can be submitted later to update the values, including the value for the bundle list URL. When this property is set to false, there is no configuration in ConfigAdmin and Device Manager server is unable to update or create properties. By default the property is set to true.
