Sub1.jsp and sub2.jsp both have only displayed text, such as slkdjflksdflakdsflasd.

Note that the forward of sub1 and sub2 in the struts-config.xml is different, and the above error occurs when sub1 is used.

My understanding: because I used the extends attribute of defination in the tiles-defs.xml, so the above error will appear, and then I did not use extends, switched to the path attribute, <definition name = "testtilessub1" Path = "/WEB-INF/pages/tilestest/sub1.jsp"/> so you can
