java - How to override struts 2.2.3.1 file upload messages? -

-

the struts.messages.error.file.too.large or struts.messages.error.content.type.not.allowed keys pose interest me. i've tried put them in "global.properties", "struts-messages.properties", , "actionname_en_us.properties" file , have not seen either 1 of messages wrote. have three <s:file> fields in form , action submitted has interceptors:

<interceptor-ref name="fileupload">     <param name="maximumsize">2097152</param>     <param name="allowedtypes">         image/png,image/gif,image/jpeg,image/pjpeg     </param> </interceptor-ref> <interceptor-ref name="securestack"></interceptor-ref>

the securestack interceptor not throw errors.
edit: here's definition of it: 

    <interceptor name="authenticationinterceptor"         class="client.interceptors.authentication" />      <interceptor-stack name="securestack">         <interceptor-ref name="authenticationinterceptor" />         <interceptor-ref name="defaultstack" />     </interceptor-stack>  </interceptors>

i used this answer , seems work when 1 file exceeds maximum size, error message appears on other 2 fields also.

since comment long answering question.

struts.xml

<constant name="struts.custom.i18n.resources" value="global" />

you can put other properties / constant in xml file

create global.properties file following

struts.messages.error.file.too.large=message struts.messages.error.uploading=message struts.messages.error.content.type.not.allowed=message

place property file in same location struts.xml file. make sure clean & build before deploying , running. sure should work.
