I have just tried the new Toolkit with a remote C-gate. First of all, I had to update C-Gate on the remote box, as Toolkit said that it was too old. That update included rebuilding the wrapper (it runs as a Windows service). Now, I am getting a bit further. This is what I am seeing in the log: INFO | jvm 1 | 2005/10/02 17:51:18 | Clipsal C-Gate(TM) v2.3.25 (build 2057) INFO | jvm 1 | 2005/10/02 17:51:18 | Warning: unknown parameter clock.updtate-interval INFO | jvm 1 | 2005/10/02 17:51:18 | License file found: INFO | jvm 1 | 2005/10/02 17:51:18 | Customer Name: PUBLIC INFO | jvm 1 | 2005/10/02 17:51:18 | Location: PUBLIC INFO | jvm 1 | 2005/10/02 17:51:18 | License type: PUBLIC INFO | jvm 1 | 2005/10/02 17:51:18 | Network licenses: 2 INFO | jvm 1 | 2005/10/02 17:51:18 | Expiry: 31 December 2099 INFO | jvm 1 | 2005/10/02 17:51:18 | Total network licenses: 2 INFO | jvm 1 | 2005/10/02 17:51:19 | WARNING - System.in can not be used when the JVM is being controlled by the Java Service Wrapper.

Clues welcome! Thanks, Nick.
