Re: [Trustedjava-support] Problem with SOAP bindings: Core service connection failed

[Ronald T. <ron...@ia...>]

Hi Benedikt,

To narrow down the problem, please (re)start the daemon and immediately 
connect to http://localhost:30004 using a web browser (before attempting 
any TPM/jTSS operation). If you find the services, it is most likely an 
issue with device access permissions.

If you don't, there is a problem with starting the daemon. What's 
written in the log file?
Also see the debain package for an example on how to configure jTSS for 
your platform.

Regards,
Ronald
