Thanks I will create the JIRA ticket. However I don’t understand your answer about my first question. What is the cause I always find the charset even if it’s not specified as a parameter ? For example if content type is application/pdf served from StreamResult I find it adds the charset even with no charset parameter on the struts.xml.
