java - JSP exception when I try to import static file -

I'm trying to import the JavaScript from a file in my Jesp used to be a line of script Can:

  & lt;% @ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core"% & gt; & Lt; Script & gt; & Lt; C: import url = "/ path / to / file.js" /> & Lt; / Script & gt;   
 The above code works 99% of the time, but I Tnkt give such notice some errors in the log:

 I found the code that throws the above exception ImportSupport.java:  
  // inappropriate to JSTL space Make foreplay reject code (irw.getStatus () & lt; 200 || Irw.getStatus () & gt; 29 9) {new Jesp Teng Akspesheshn (Irv .getStatus () + "+ + strip session (Lcshyuarel)); }   
 It seems that the servicelet response code is 304.  
 Why is the question? Is this a bug or am I missing something?  
  Update:   
 The problem only occurs when the incoming request is modified-  
  Update 2:   
 I solved this problem - since removed the static files and removed the header from each request.   
  itemprop = "text"> 
 I have been using ResourceHttpRequestHandler of Spring MVC (with MVC configured: resource) using my fixed resources By serving / processing / * and it returns 304 returns to incoming requests, which use-modified-as headers. If there is an import and incoming request since the modified header I get javax.servlet.jsp.JspTagException :: So when I include such a static resource with C Error 304  
 I have a choice, including the dynamic @, is not an option, and uses resources in an illegal manner in JSP, in which the resource is attempting to incorporate the URLs operated by the HTTPPequesthandler. So I was included in my own writing which reads from the file and writes it in JSP:  
  & lt;% @ page import = "org.springframework.web.context .support. SerialcontactRSourceloader, org.springframework.core.io.Resource "%> & Lt;% @ Page Import = "org.apache.commons.io.IOUtils"%> & Lt;% string path = "/resources/fileName.html"; ServletContextResourceLoader Loader = New ServletContextResourceLoader (getServletConfig). GetServletContext ()); Resource processing = loader.getResource (path); IOUtils.copy (contentResource.getInputStream (), pageContext.getOut ()); & Gt%;
