This page of the JPP Wiki provides a list of the Java libraries needed to build and run OpenJUMP. These are also known as "build dependencies".
| Library Name | File Name | Library Home Page | Dependency Description |
| Bouy | Bouy.jar | http://buoy.sourceforge.net/ | Provides functionality for some GUI components in OpenJUMP. |
| JAMA (A Java Matrix Package) | Jama-1.0.1.jar | http://math.nist.gov/javanumerics/jama/ | ? |
| Batik | batik-all.jar | http://xmlgraphics.apache.org/batik/ | Provides SVG rendering and import/exp |
Spatial Relationships
I'd like to get some comments and advice on an implementation of spatial relationships for OpenJUMP using JTS as the underlying geometry model. I've written a coupel of articles about spatial relationships for the OSGeo Journal and this implementation will be part of an effort to provide working open source code as an example of the concepts discussed in the article.
Here is a list of the possible ways that I imagine a library or OpenJUMP plug-in that added support for spatial relationships could be used:
Enhanced Spatial Query Functionality
The spatial relationship code be used to add support for enhanced spatial queries. For example the user could ask for the billboard (represented by a point) that was closest to a segment of freeway (represented by a line string).
The spatial relationship code would enhance queries in two (2)

Here is a HOWTO for creating a new Open Wizard, excluding a File Layer
which uses the Open File plug-in mechanism.
1. Define your wizard class to implement
org.openjump.core.ui.swing
org.openjump.core.ui.swing
AbstractWizard group there are 3 arguments, the display name and icon to
display in the Open Wizard and the last is the ID of the first wizard panel.
public class WFSWizard extends AbstractWizardGroup {
private static final String KEY = WFSWizard.class.getName();
public WFSWizard() {
super(I18N.get(KEY), IconLoader.icon("wfs.gif"), WfsWizardPanel.getClass().getName());
}
:
}
2. Implement the initialize method on your wizard to create the panels
for each time the wizard is shown. The reason you don't do this in the
constructor is that the information you need may not be
