Hi All,

I need help ...

  I'm using the Tomahawk library in our project. In web.xml I have an= entry as follows ...,
--------------------
   = <filter>
   <filter-name>MyFacesExtens= ionsFilter</filter-name>
   <filter-class>org.apache.myfaces.component.html= .util.ExtensionsFilter</filter-class>
     <= ;/filter>


&= nbsp;    <filter-mapping>
   &= nbsp;      <filter-name>MyFacesExtensionsFilter&l= t;/filter-name>
                    <servlet-name>Face= s Servlet</servlet-name>
     </filte= r-mapping>

          <filter-mapping>
  &nbs= p;      <filter-name>MyFacesExtensionsFilte= r</filter-name>
          <url-pattern>/f= aces/myFacesExtensionResource/*</url-pattern>
   &n= bsp; </filter-mapping>
      &= nbsp; <filter-mapping>
      &= nbsp;    <filter-name>MyFacesExtensionsFilter</filt= er-name>
           <url-pa= ttern>*.jsf</url-pattern>
       = </filter-mapping>
       = <filter-mapping>
       =     <filter-name>MyFacesExtensionsFilter</filter-na= me>
           <= url-pattern>*.jsp</url-pattern>
   </filter-mapping>
------------------= -------

In the project I have download code as follows :

pr= ivate void copyFileToResponse(HttpServletResponse response, FileInputStream= fileIn) throws IOException {
       = int BUFF_SIZE=3D4096;
   byte[] buffer =3D new byt= e[BUFF_SIZE];
   ServletOutputStream responseOutStream =3D response.ge= tOutputStream();
         Buffer= edInputStream buf =3D new BufferedInputStream(fileIn);
   = ;      int n =3D 0;
    &nb= sp;    int count =3D 0;

  while= ((n =3D buf.read (buffer)) !=3D -1) {

       = ;
//     &= nbsp;      responseOutStream.write(buffer);
&nb= sp;            LOGGE= R.info("while loop : before write to Buffer and count =3D> " += count);
          &nb= sp; responseOutStream.write (buffer,0,n);
         &nbs= p;   count +=3D n;
       &= nbsp;
         = ;    LOGGER.info("while loop : copyFileToResponse flush= ");
          &nb= sp; responseOutStream.flush();
      = ;       LOGGER.info("while loop : copyFi= leToResponse flushBuffer");
            = ; LOGGER.info("while loop : after buffer read");
  &= nbsp;      }
     &nbs= p;   LOGGER.info("after while loop : before flushbuffer"= ;);
         buf.close();
&nb= sp;        LOGGER.info("after while= loop : before flushbuffer");
         response.flushBuffer()= ;
         responseOutStream.clo= se();
         LOGGER.info("= ;after while loop : after flushbuffer");
}

= ;
My problem is as follows,

If I hav= e the mentioned entries in the web xml and I'm trying to downlaod > 100 = MB file,=20

the above code, throws

"java.l= ang.OutOfMemoryException : Java heap space"

org.ap= ache.catalina.connector.CoyoteOutputStream.

But it works= fine if I remove the entries from the=20 web.xml file.

I have debuuged and found that if I keep a= bove "MyFacesExtensionsFilter" related entries in web.xml, the re= sponse is instantiated from org.apache.myfaces.component.html.util.Extensio= nsResponseWrapper , in which case flush() doesn't work and causes the "java.lang.OutOfMe= moryException : Java heap space" error.

If I remove= the MyFacesExtensionsFilter related entries, the response gets instantiate= d by
"org.apache.catalina.connector.CoyoteOutputStream", in whic= h case flush works fine.


Can anyone tell= me how to avoid this situation by still maintaing the "MyFacesExtensi= onsFilter" related entries in the=20 web.xml.
