Solution 1:[1]

The path attribute should be absolute. According to the struts-config_1.3.dtd

path - The module-relative path to the resources that is encapsulated by the logical name of this ActionForward. This value should begin with a slash ("/") character.

But it is different if you use a tiles request processor. Put the following line to the struts-config.xml:

<controller processorClass="org.apache.struts.tiles.TilesRequestProcessor"/>
