Enhancement trouble

Question

Kodo newbie seeks explanation of exception occurring during
enhancement. My 'package.jdo' contains mappings for a dozen or so
classes to an existing schema. Most of the classes contain no JDO code
and get enhanced with no problem. Two of the classes are intended for
readonly use; they're sort-of-singletons that initialize all allowable
instances of themselves from storage at class load time. The only
thing that differentiates these classes from the others is their
initialization code. When I run the enhancer over these classes, I get
the following exception:
Exception in thread "main" java.lang.IllegalArgumentException: The
specified class "com.commercehub.
carrier.ServiceLevel" could not be loaded. null
at
com.techtrader.modules.tools.compiler.ClassArgParser.parseClasses(ClassArgParser.java:65)
at
com.techtrader.modules.jdo.enhance.JDOEnhancer.main(JDOEnhancer.java:80)
Here's the method that contains JDO code: (The JDOFactory mentioned in
the code is the same one distributed with the Kodo tutorials.)
private static void allInstances() {
PersistenceManager pm = JDOFactory.getPersistenceManager();
Extent cln = pm.getExtent( ServiceLevel.class, false );
Query qry = pm.newQuery( ServiceLevel.class, cln );
Collection results = (Collection) qry.execute();
Iterator it = results.iterator();
while (it.hasNext()) {
ServiceLevel nextType = (ServiceLevel) it.next();
String key = nextType.getCarrierString() +
nextType.getCode();
cache.put( key, nextType );
Could I impose on someone with source code to look at the line in
question and suggest what might be failing?
Thanks,

an artifact of your post, or did the error message have that newline
in it? If the latter, what was the command that you executed in order
to run the enhancer, and can you post the contents of your
package.jdo, system.jdo, or ServiceLevel.jdo file?
