Subject Re: Exception running RunOptimizerTest
Date Fri, 18 Dec 2015 22:11:19 GMT
Hi Bryan,

thanks for your response; my answers below.

Yes, this is a version of Derby I have built from source; specifically,
trunk revision 1720848

The steps I take are:

I build per build page
<http://svn.apache.org/repos/asf/db/derby/code/trunk/BUILDING.html>.
http://svn.apache.org/repos/asf/db/derby/code/trunk/BUILDING.html
The jardriftcheck step fails (see error below), but the jars are built (see
listing below).

Then, I run RunOptimizerTest.java within netbeans by right clicking on the
file and selecting "Run File".
This gives the output shown in my first mail.

It seems like some setup is missing; do I need to create a database before
attempting to run the test?  Is the jardriftcheck error
a blocker? Do I need to resolve that before trying to test?

The netbeans project does show errors in some modules (mostly not being
able to resolve packages like javax.servlet)
I followed the instructions here to load derby in netbeans:
http://wiki.apache.org/db-derby/BuildingDerby#Using_NetBeans_to_Build_Derby

I'd like to get to the stage where I can debug/step through the derby code,
so any help much appreciated!

Thanks,
Colm.
