The eclipse I use is 3.2.1,3.2.* should all be the same
First to http://www.eclipse.org/vep/.
Download Emf-sdo-runtime-2.2.0.zip,gef-runtime-3.2.zip,ve-runtime-1.2.zip and unzip them to your favorite catalogue.
Mine is g:/smarteclipse/plugins/3.2/visual.editor.runtime.
These plugins are then installed in links mode.
I initially chose Emf-sdo-runtime-2.2.1.zip, the result is installed after the error: cannot Create Remote JVM for Visual Editor for Java
It would be nice to change into a emf-sdo-runtime-2.2.0.zip later.
The reason is I think my eclipse is 3.2.1 version, so I should choose emf-sdo-runtime-2.2.1, and I was wrong, and Visual editor was too demanding on the version requirements of the dependency plugin.
Unlike SWT Designer, Visual Editro does not have a corresponding option in the new project, nor is there a preference inside. At first I thought it was not a successful installation.
After knowing the new Java class icon on the toolbar, click on the small arrow on the right, and "visual Calss" appears on the extended menu below. This is the entrance to Visual editor.
You can also set it in a Window->customize perspective pop-up window:
Submenus Select New, shortcut categories hook on java->swing.
Write it down for backup.
