SmartGWT *.ds.xml files can be accessed via web browser

I have a Web Maven project that uses SmartGWT. After doing maven install, several *.ds.xml files are created in the install folder under sc/schema subfolder. These files are:

DataSource.ds.xml
DataSourceField.ds.xml
DataSourceStore.ds.xml
DBListDS.ds.xml
DBSchema.ds.xml
JVMClassTreeDS.ds.xml
QuartzJobs.ds.xml
QuartzScheduler.ds.xml
QuartzTriggers.ds.xml
SchemaSet.ds.xml
SimpleType.ds.xml
Validator.ds.xml
WebService.ds.xml
WebServiceOperation.ds.xml
WSDLMessage.ds.xml
WSOperationHeader.ds.xml
XSComplexType.ds.xml
XSElement.ds.xml

They can be accessed via browser at my website link my_site/*.ds.xml, which the browser display a red error message. I have searched around and found nothing related to accessibility via browser of these files.

How do I restrict access to these files? Will the pose any vulnerability issue? Is it safe to let them be?

Thanks

Solution

It is perfectly safe to leave those files accessible.

In fact the application may need to access them from the client site to function correctly.
