>             Project: Cayenne

>         Environment: Windows 10

> When selecting a custom class generation template in Modeler, DataMap - Class Generation
panel, the exception as below occurs.
> 1) As root cause, line URI/URL to Path conversion in line #170 of org.apache.cayenne.modeler.CodeTemplateManager.java
could be identified: The prior conversion from the data map 'root path' to an URI inserts
a trailing '/' in front of the drive letter on Windows systems. This slash is not removed
by the used sequence
> {code:java}
> rootPath.getURL().getPath(){code}
> anymore and causes the exception. The pattern 
> {code:java}
> rootPath.getURL().toURI()
> {code}
> works (on Windows).
>  
> 2) After fixing the issue above, the template selection worked but the template files
have not been loaded by cgen. Root cause: Modeler creates template paths relative to the location
of the DataMap.xml file. This relative path cannot be resolved by cgen.
> Possible solution: Add DataMap root path to the base path map of the generator action
> {code:java}
> org.apache.cayenne.gen.ClassGenerationAction.java#285, getTemplate(...)
> if (cgenConfiguration.getRootPath() != null) {
>      props.put("cayenne.resource.loader.path", cgenConfiguration.getRootPath().toString());
> }
> {code}
>  
> Please see attached patch addressing both tightly related issues for details.
