  Important changes

Due to fundamental changes in the Java-Technology since the Java Runtime 1.7.0_25 You can only start CityGuide DMS via Http-Connections !

For this, please read the following changes ...

The use of CityGuide DMS via the file-protocol for local file-level apps or network-drives is not longer allowed for security reasons and will not longer be supported !
When you start CityGuide DMS via an Internet-address, there are no changes in running the software. You can start the software as usual on the Web-page of the provider and use it.

For the execution of CityGuide DMS via a local network, you should use for the future a local HTTP Server (such as IIS or Apache), as the file-protocol is not longer allowed.

To use CityGuide DMS via a local application/CDROM/DVD you should use the new Starter. Read more about this in the next sections ...

If you have any questions about these changes, please contact your administrator or contact our Online-Support, we will help you to find a solution.


  Local Application/CDROM/DVD

To use a local application/CDROM/DVD of CityGuide DMS you should use the Starter. This is a mini-webserver, which can be used locally only in conjunction with the used application of CityGuide DMS on the same workstation.

The job of the Starter lies in providing your local CityGuide-version to the Java-Runtime over an HTTP connection, because local file connections are no longer allowed.

To do this, open your file manager and execute the file "Starter.jar" in the main directory of the application. When using on CDROM/DVD's on Windows, the Starter should be executed automatically via Autorun after inserting the media ...

Now you should see the Desktop of the Starter ...


The Starter is now offering you the opportunity to use the specified product of CityGuide DMS at the the given address in a browser of your choice ...

Starts the specified version of CityGuide DMS in your default browser on the specified address.
Copies the given address to your clipboard. Now start a browser program of your choice and paste the address there in.
Displays this help page.
Exits the Starter. The application is no longer available at the given address.

 Important notes:

If the Starter is missing on the CDROM/DVD, your product contains an older version of CityGuide DMS. In this case, you can use the product only with a Java-Runtime version 1.7.0_21 or earlier! !

When executing the Starter please ensure, that a local port address between 8888 and 8899 is available, which has not previously been occupied or blocked by other programs !

If you have further questions about the Starter, please contact your administrator or our Online-Support. We're here to help.
