Re: [udig-devel] Logging in uDig, DB2 JDBC driver setup

[David Adler <dadler@xxxxxxxxxxx>]

Hi Jody, thanks for the quick response.

I'm using uDig 1.1.1.

Does uDig access the JDBC drivers from the location specified in the 
preferences or does it copy them to the uDig install tree?  It looks 
like it does the latter.

These are the log messages from the attempted connection to the DB2 for 
z/OS database.  This is after filling in the all the connection 
parameters & database name and then clicking on the drop-down box for 
Schema:
!ENTRY net.refractions.udig.catalog.ui 4 0 2008-12-02 06:45:30.343
!MESSAGE
!STACK 0
java.lang.NullPointerException
   at 
net.refractions.udig.catalog.internal.db2.ui.DB2WizardPage.getConnection(Unknown 
Source)
   at 
net.refractions.udig.catalog.internal.db2.ui.DB2WizardPage.populateSchema(Unknown 
Source)
   at 
net.refractions.udig.catalog.ui.wizard.DataBaseRegistryWizardPage.focusGained(Unknown 
Source)

There is no error message displayed.  It just shows the progress bar for 
a few seconds and stays in the same state.

The same symptoms occur if you specify some invalid parameters like port 
number for a valid DB2 LUW database.

Is the uDig source still available?  I looked in 
http://svn.geotools.org/tags/udig1.1 but this seemed to be a version of 
GeoTools source.
