Hi Paul,
I am looking for a way by which we could differentiate between template
errors and code errors through JET tags.
For example, I have a scenario where I create a DAO file through template.
During file creation,another file exists with name 'Dao'.
Currently,the error thrown by JET is:
Error: org.eclipse.core.internal.resources.ResourceException: A resource
exists with a different case:
'/credentials-integration-dao/src/test/java/com/accenture/ad sj/credentials/dao/PersonDaoHibernateTest.java'.
And then, a pop up window appears saying:
An internal error occurred during: "Launching web-templates
(FlowTest.xml)".
java.lang.NullPointerException
This error message seems to look like
org.eclipse.core.internal.resources.ResourceException - eclipse framework
exception and it is a naming/runtime exception.
Actually,is there a way to catch this exception and give different error
message.
Ideally,error/exception can be logged but flow should be allowed to
continue in template execution which does not happen here as a model
pop-up window appears stopping flow.
Is there a way to achieve this exception handling?
Kindly let us know soon.
Best regards,
Justin.

Justin:
Sorry for the slow reply.
I'm a little confused by the situation. I understand the ResourceException.
But I don't know what's happening to cause the pop-up and the NPE. What
version of JET are you using?
In general, JET doesn't have a good exeception/error mechanism. The tag
handlers trap any exceptions, log them and then let execution proceed as
normally as possible. The file IO does actually happen until after all
templates have executed - perhaps the exception handling isn't right in
there.
Any snippets of could you can share would be helpful.
