[forge-issues] [JBoss JIRA] (FORGE-1422) REST addon should support generation of exception mappers for validation errors

[Vineet Reynolds (JIRA)]

    [ https://issues.jboss.org/browse/FORGE-1422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934296#comment-12934296 ] 

Vineet Reynolds commented on FORGE-1422:
----------------------------------------

We'll need to bring in exception mapping support like the one in Jersey: https://jersey.java.net/documentation/latest/bean-validation.html#d0e11775

Unfortunately, that is not standardized. For JBoss EAP based REST resources, we may wish to do something similar in RESTEasy, to serialize BV errors into HTTP responses.

> Currently a HTTP 500 response is generated for validation errors encountered during processing of POST/PUT requests that create or update JPA entities. The 500 response contains a stacktrace that cannot be parsed by clients to evaluate what failed.
> We should generate exception mappers that can map Bean validation errors to help generate parseable responses (for the REST clients).
