我也遇到了同样的问题，但是现在解决了，如下：ExampleTextAction.javapackage sample;public class ExampleTextAction { public String preview() throws Exception { return "textreport"; } } struts.xml<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <package name="text-example" namespace="/sample-text" extends="struts-default"> <action name="test" class="sample.ExampleTextAction" method="preview"> <result name="textreport" type="plainText"> <param name="location">/test.jsp</param> </result> </action> </package> </struts>说明： struts.xml file should have a result name as textreport with type as plainText and having location param pointing to the actual text file, whose content is to be shown on screen as plain text.
<action name="EA0001Code" method="doCode"
class="ea0001Action">
<result type="plainText">
<param name="location">
/WEB-INF/jsp/debug/expres/aognl/EA0001.jsp
</param>
<param name="charSet">UTF-8</param>
</result>
</action>
<action name="plaintext">
<result type="plainText">
<param name="location">/index.jsp</param>
<param name="charSet">UTF-8</param>
</result>
</action>

public String preview() throws Exception {

}
}
struts.xml<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC

method="preview">
<result name="textreport" type="plainText">
<param name="location">/test.jsp</param>
</result>
</action>
</package>
</struts>说明：
struts.xml file should have a result name as textreport with
type as plainText and having location param pointing to the
actual text file, whose content is to be shown on screen as plain
text.
其结果，是一样的！
