[CONF] Apache Sling: Effective Exceptions (page created)

[confluence]

Page Created : SLING : Effective Exceptions Effective Exceptions has been created by Felix Meschberger (Dec 23, 2007). Content: Rethinking the SlingException Status: DRAFT Created: 23. December 2007 Author: fmeschbe Inspired by Barry Ruzek's article Effective Java Exceptions, I went out to revisit the exceptions we have defined in the Sling API. This is what I came out with: We have 4 Exceptions, all of which are checked exceptions The SlingException is a base exception and is declared almost everywhere The HttpStatusCodeException is an IOException not a SlingException and is not declared to be thrown anywhere We have to documented possibilities of throwing a runtime exception: The AccessControlException possibly thrown when accessing a resource through the ResourceResolver. Thinking about these (checked) Exceptions, I propose to change this situation as follows: The SlingException is a RuntimeException and is used as the base exception for all exceptions defined by the Sling API.
