Hi, Isaac and Rajeev and everyone else ...
I got a good result by following this advice, though with a few bumps.
I'm posting a (hopefully) good accounting here so that this post can
be helpful to others.
As originally described, I was trying to create a project that
contains common constants in a .java file. I expected other projects
to "import static ..." to get to the constants.
To do this, I created a GWT project and then adjusted it. I added a
<source> directive to the Definitions.gwt.xml file, and I removed
unneeded client, server, and Public directories. As a result, my
Definitions project directory and the referencing project looks as
show below.
PALMS_Definitions
+bin
+src
+org
+paceproject
+palms
+definitions
+schema
ClassDefinitions.java
Definitions.gwt.xml
.classpath
.project
The ClassDefinitions.java file contains the common constants.
The Definitions.gwt.xml file contains:
<module>
<inherits name="com.google.gwt.user.User"/>
<source path="schema"/>
</module>
I assume that the gwt-user.jar is already available to the project via
the .classpath file.
For completeness, my .classpath file has:
<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path="src"/>
<classpathentry kind="con"
path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry kind="var" path="GWT_HOME/gwt-user.jar"/>
<classpathentry kind="output" path="bin"/>
</classpath>
My .project file has:
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>PALMS_Definitions</name>

</buildSpec>
<natures>
<nature>org.eclipse.jdt.core.javanature</nature>
<nature>com.swtdesigner.gwt.GWTNature</nature>
</natures>
</projectDescription>
As for the project that references this project, the Projects tab in
the Build Path dialog most have PALMS_Definitions added in.
Once all of this is true (and, maybe, the projects are all rebuilt),
there should be no more source errors deriving from the GWT
compilation.
