[Geoserver-devel] Why in debug mode, the Map Preview page don't display any dynamic information except static lables?

hello all,

I am a new to study Geoserver, and I used the debug mode to study how the
Geosever work, then to
develop my functions.
Here is my quesiton. When I debug the project, it can run. But when I click
the link of Map Preview, there isn't any dynamic data displaying,except some
static labels like Layer (NameSpace:FeatureType) Preview Map. I found in the
source file of MapPreviewAction.java, the size of ftypes (List) is 0, thus,
the the size of Arraylist dsList, ftList,..., all are 0. That maybe why
don't display dynamic data.

So why the size of ftypes (List) is 0 in debug mode? How can I display the
dynamic data in debug mode?

Thanks.

Vincent.

It seems that in debug mode you're playing against an empty data directory? That's the most likely cause at least, that when in debug
your GeoServer is configured differently than when you're not debugging
it.

Yes, you are right. In the debug mode, the data directory is empty. So I copy
some data from a release folder to replace the empty one. And then my
problem is resolved.
Thank you, Andrea.

Hi,

did you start GeoServer with a data directory ? In the Arguments tab, add to VM arguments:

-DGEOSERVER_DATA_DIR=/home/username/geoserver/1.7.x/data/release
