I have a JSP that uses an ActionTag <s:action> to call a Struts 2 action
class directly from the JSP. But in the action class, the HTTP response
has already been committed. This makes it impossible for me to set cookies
from my action class.
I tested this by calling HttpServletResponse.isCommitted() is my execute()
method of my action class, and it returns true.
Is this a bug? Why is the response committed if the JSP hasn't finished
rendering?
--somePage.jsp--
<s:action name="someAction" executeResult="true"
ignoreContextParams="false" />
--struts.xml--
<action name="someAction" class="com.dev.MyAction" method="execute">
<result>/page.jsp</result>
</action>
--MyAction.java--
public String execute()
{
System.out.println("response.isCommitted() = " + response.isCommitted());
//this prints true
}
Thanks,
David
