Pay attention to this below:
protected void makeResults(Class<?> actionClass, String path, String
resultPrefix,
Map<String, ResultConfig> results, PackageConfig packageConfig,
Map<String, ResultTypeConfig> resultsByExtension) {
if (path.startsWith(resultPrefix)) {
"if (path.startsWith(resultPrefix)) {", it is important.
Not all backup files ended with "bak" will cause this error.it must satisfied
the condition:
====================================================
path.startsWith(resultPrefix)
====================================================
> Unable to find a result type for extension

> Key: WW-3564
> URL: https://issues.apache.org/jira/browse/WW-3564
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Convention
> Affects Versions: 2.2.1
> Environment: windows xp, spring 2.5, tomcat 5.0.28,
> struts2-convention-plugin-2.2.1.jar
> Reporter: Dan Du
> Priority: Blocker

>
> I set a convention constant like this below:
> ==========================================================================================
> <constant name="struts.convention.result.path" value="/WEB-INF/jsp" />
> ==========================================================================================
> After I deployed my project to tomcat server, I backup a file "search.jsp"
> and named the backup file with "search.jsp.bak", There is a class named with
> "SearchAction"。The action's search method is annotated by @Action, like this:
> ==========================================================================================
> @Action(value = "search", results = { @Result(name = "search", location =
> "/WEB-INF/jsp/search.jsp") })
> ==========================================================================================
> When I startup tomcat server, I recieved some message:
> ==========================================================================================
> Unable to find a result type for extension [bak] in location attribute
> [/WEB-INF/jsp/search.jsp.bak]. - [unknown location]
> ==========================================================================================
> Then I checked org.apache.struts2.convention.DefaultResultMapBuilder.java, I
> found this exception throwing at line 527。
> I debug that snippet, At line 269, I found some
> problems,ServletContext.getResourcePaths() method will scan a directory and
> its sub-directory and return all files in these directories, If a file's
> extension is not jsp, jspx,vm,ftl,html or htm。 I would get the error。
> So I think this code need to be change to fix this problem。
