Error parsing tiles-defs.xml when starting test server after store migration

After migrating your store assets project, you get an error when starting your test server.

Problem

An exception similar to the following example occurs:

[12/22/09 13:13:11:859 PST] 00000012 WASSessionCor I SessionContextRegistry getSessionContext SESN0176I: Will create a new session context for application key WC_default_host/webapp/wcs/stores

                                 javax.servlet.ServletException: org.apache.struts.tiles.DefinitionsFactoryException: IO Error while parsing file '/WEB-INF/tiles-defs.xml'. Connection timed out:

Solution

Your tiles-defs.xml file has the wrong DTD version in its <!DOCTYPE> element. Your element may look similar to the following sample:

<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration//EN" 
   "http://jakarta.apache.org/struts/dtds/tiles-config.dtd">

Change this element as shown in the following sample:

<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 1.1//EN"
                                   "http://struts.apache.org/dtds/tiles-config_1_1.dtd">

Note: After making this change, restart your test server.
