I'm using Struts 2.2.1 and tiles 2.1.4.
Wanted to know if there is a way to have multiple tiles-def xml files as my tiles-def xml file is becoming really big.
Not sure but i believe you need to pass param
to Tiles listener in web.xml
something like
<context-param id="struts_tiles">
<param-name>org.apache.tiles.impl.BasicTilesContainer.DEFINITIONS_CONFIG</param-name>
<param-value>/WEB-INF/classes/file1.xml,/WEB-INF/classes/file2.xml</param-value>
</context-param>
Code above is not tested :)
