Both JDataStore Server (JDSServer) and JDataStore Explorer (JDSE) are launched with an option that points to its documentation. This parameter used to be -h. Now it is -doc. The Start Menu shortcut that the JBuilder installer creates for JDSServer and JDSE still has the old -h parameter.

In order to fix this bug you need to change the parameter of both tools from:

-h=..\doc to -doc=..\doc

Here are the steps Windows:

1. Right-click on the Start button and select Explore.
2. Navigate to the JBuilder program folder.
3. Right-click on top of the "JDataStore Server" short-cut and select Properties.
4. Modify the command-line as indicated above.

Repeat for the "JDataStore Explorer" short-cut.
