JSP exceptions are hidden by Tiles making debugging difficult
-------------------------------------------------------------
Key: TILES-516
URL: https://issues.apache.org/jira/browse/TILES-516
Project: Tiles
Issue Type: Bug
Reporter: Clayton Rabenda
When using tiles:insertDefinition, any exceptions thrown by the jsp renderer
are being hidden from the logs by TilesContainer.
Based upon apache's logging best
practices(http://commons.apache.org/logging/guide.html), I believe it would be
best if exceptions caught in TilesContainer's render methods were logged before
being rethrown.
"External Boundaries - Expected Exceptions. This classification includes
exceptions such as FileNotFoundException that cross API/SPI boundaries, and are
exposed to the user of a component/toolkit. These are listed in the 'throws'
clause of a method signature.
Appropriate handling of these exceptions depends upon the type of code you are
developing. API's for utility functions and tools should log these at the debug
level, if they are caught at all by internal code.
For higher level frameworks and middleware components, these exceptions should
be caught immediatly prior to crossing the API/SPI interface back to user
code-space, logged with full stack trace at info level, and rethrown. The
assures that the log contains a record of the root cause for future analysis in
the event that the exception is not caught and resolved as expected by the
user's code. "
