NullPointer Exception when tiles servlet is not defined
-------------------------------------------------------
Key: TILES-134
URL: https://issues.apache.org/struts/browse/TILES-134
Project: Tiles
Issue Type: Improvement
Components: tiles-jsp (jsp support)
Affects Versions: 2.0.2
Environment: Tomcat 5.5.20, jre1.5_06
Reporter: Scot Meyer
When implementing a simple template and the tiles servlet is not defined in the
web.xml you get a NullPointer exception at line 144 when running. This can be
difficult for the implementer to realize what they did wrong. A suggestion
would be to throw and exception when the context is null. It might be better
to throw a TilesException however the interface defines a JspException so I
used it.
