[Gistoolkit-editor] gistoolkit and DB2 spatial extender

[Johannes <joh...@od...>]

Hi,
I am trying to build an application with gistoolkit and the db2 spatial
extender. i am more or less a newbie in Java programming so  i have a few
questions. Trying the binary code and setting up the a layer (an shapefile
example) i was asked on the client site to install the java plugin version
1.3.1.2. is there a way to change the version of this required plugin,
because i only have java 1.4 installed. Probably i have to build the
source code by myself, to get rid of the plugin version. therefore i
wanted to checkout the cvs on sourceforge, but it doesnt work: after 
cvs -d:pserver:ano...@cv...:/cvsroot/gistoolkit login
i got the message 
cvs [login aborted]: end of file from server (consult
above messages if any)
for the password i just pressed the enter key as described at sourceforge.
any ideas?
is there a simple way to integrate the gistoolkit into tomcat?


Thanks for any help

Johannes

[Gistoolkit-editor] gistoolkit and DB2 spatial extender

[<it...@at...>]

Hi, and welcome to the GISToolkit lists.  We are
still developing the GISToolkit, and are working
on an Oracle connector at the moment.  The DB2
Spatial extender Data source is operational and
well tested.  It works with Jdk 1.2.0 and above,
so there should be no trouble working with 1.4.

I just noticed the other day that the GISToolkit
Server sends HTML to the client that requests the
specific version of Java.  I did this because of
problems with compatibility and the JDK 1.1 that
exists on most Windows machines.  This can be
easilly changed to a different version by editing
one of the class files.

gistoolkit.server.mapservice.clientextender.ClientExtender

But you can use the htmlclient just as easilly.
This will not require a jdk version.

If you are having trouble with the CVS archives,
the source code for the GISToolkit can be
downloaded in .zip format from a link on the home
page, developers corner.  This is the cutting
edge, most recent build of the toolkit, and should
be consistent with what is in CVS.

I have been giving the "Tomcat" problem some
thought lately.  We have written tomcat servlets
which just access the Web Map Service and server
the images that way.  It may or may not be simple
depending on how you wish to go about it.

Finally.  Feel free to send me e-mail directly.

Thanks,
Ithaqua

Hi Ithaqua,
i have also discussed the use of gistoolkit with the db2 spatial extender
with knut solze one of the main developers of ibm.
he pointed to use queries like=20

" ...
> This code is also not documented and, thus, simply not
> supported.=A0=A0For=A0all
> your purposes, there aren't any tables like "db2gse.gse_*".=A0=A0Stick=A0=

> WHERE=A0=A0srs_id=A0=3D=A0..."

instead the one used in the current version of gistoolkit.=20
i thing it might be a good idea to write some java code which can be easily
used in other opensource gis applications like geotools or geoserver as
well. Is there a road map for the future development of the gistoolkit??

I'm not from the Gistoolkit team, but have noticed that no one is respondin=
g=20
to this list anymore.

With regards to CVS, I've noticed that there have been problems with CVS on=
=20
sourceforge lately.  It is probably working again now.  It not, try using t=
he=20
ssh interface to sourceforge.  It has been more reliable lately.  Eg:
cvs -d:ext:cam...@cv...:/cvsroot/geotools checkout geotools

Also of note, if you are looking for a java gis project with an active=20
development community behind it, you might want to check http://geotools.or=
g=20
=2E  (I think gistoolkit-editor is based on early versions of geotools).

i have already looked at it, but as far as i know there havent developed 
an DB2 Spatial Extender Connector. Thats why i looked at the gistoolkit.
The first try didnt work with my db2 8.1 spatial extender
(new funktions). so i changed the code a little bit for my personal use,
and it worked. 
But anyway, perhaps its better to use a programm of an active developing
community like geotools or geoserver. it should not be so difficult to
make use of the gistoolkit code and implement it into the other programms. 
i will try to do it. 
Perhaps someone else want to work with db2 spatial extender too.
