If instead I disconnect from the network then the application starts without problems, connecting to localhost, however then in the demos practically no data is downloaded and the only thing I can do is then to buildup knowledge networks myself by adding semantic media wiki code …

can you please describe how to fix it on windows so that it works also when the laptop is connected to the internet ?

furthermore, it is not clear to me how to customise it … namely how to include my own data/ knowledge bases / triplestores … by programming or by configuration ? where ? how ?

This pretty much looks like either a firewall problem or a problem with a
port already in use by another application to me. If it is possible,
try to switch off the firewall or open up port 8888, since I do not
think that any other application uses port 8888 ba default.

Hello,

I also have a problem, running the Demo (on Windows 7, IW-Version fiwb0.9_build202_dist). My error, when I try to search, e.g., for http://localhost:8888/ws/Earthquake is the following:

Hi Benedikt,

we released and uploaded a new version
of the Information Workbench Open Source edition (v1.0.1 SDK), please
use this one instead since many problems with the old version have been
fixed and a lot of new features have been added, one of these problems
is the DB-driver-problem you experienced.

Additionally,
there will be a first version of a detailed documentation for setting
up, using and administering the Information Workbench, until then please
contact me via this forum or via email if you encounter any other
problems.

Regards,

Tobias
